Synedrex Review - Does This Weight-Loss Formula Work? Are side effects and ineffectiveness deal breakers?

PUBLISHED: 05/03/2016 | BY: SUMMER BANKS, SENIOR REVIEWER
Editor's Review: 3.5 / 5.0
Synedrex Review

A diet product’s worth depends on whether it actually helps people lose weight. Let’s find out if Synedrex really works. We needed to learn as much as possible about the ingredients, side effects, clinical support and customer service. We also took a long, hard look at customer experiences. We processed and condensed to give you the info you need.

EDITOR'S TIP: Substitute Synedrex with a proven fat burner such as Leptigen for better results.

What You Need to Know

Let’s start with the fact that Synedrex is a “thermogenic” supplement with B vitamins, caffeine, sulbutiamine, yohimbine extract and other ingredients. You can take up to two capsules a day, though you may want to start with one according to the directions. The small container means there’s no trouble taking them on the go.

The start date of Metabolic Nutrition, the company behind Synedrex, is not listed on the official website, but we know the business started online in 1997. That’s quite a while to be on the supplement market. We like that the ingredients are available for the dieter and the BBB rating for several locations is good, but read on…

Side Effects – “Do You Need to Worry?”

The first negative we found was with Synedrex side effects. “No dieter wants to feel shaky and jittery after taking a product,” says our Research Editor. “You can have increased energy and metabolism without the problems.”

As one dieter puts it, “The side effects while on it included excessive sweating, jitters and insomnia.”

Another user reports even more Synedrex side effects, ”It gave good energy, but it was too much. It made my heart feel racy.”

During our research, we did stumble on a few dieters who didn’t have the same problem. One said, “The first day I started I got incredibly hot and enough energy to last a week, had a little trouble sleeping but by day 2 that pretty much went away.”

A customer shared, “I haven’t had any of the side effects listed in any of these reviews.”

Ineffective – “Frequent Complaint”

Probably one of the biggest issues with a weight-loss supplement like this is effectiveness. According to some, Synedrex ingredients do nothing to help you lose. “II didn’t lose any weight. I will look for a better fat burner,” a user reports.

Another dieter with the same problem says, ”There was no change in my weight at all.”

We did read some supportive comments along the way. As one user said, “Keeps me going. Makes me sweat.”

Another commented, “I only take one pill per day, in the morning and feel it helps sustain my energy all day.”

You only need one negative, like a negative reaction, to ruin your chance of long-term weight-loss success. In the case of Synedrex, if the side effects are as harsh as dieters report, that’s a bad sign.

The Science – “Is There Proof?”

We visited the Science Center portion of the Metabolic Nutrition website to see if there was any support for the weight-loss product. We found articles about supplements and exercise, but no research. The most important parts are caffeine and yohimbe, two stimulants. We know these ingredients boost energy and promote a stronger metabolism, but too much can do more harm than good. Based on the side effects there may be too much in Synedrex. At DietSpotlight, we need proven facts to support claims. If there’s none out there, or if the formula may cause issues, that’s not a good sign.

The Bottom Line – Does Synedrex Work?

Yeah, so what’s our final take on this one? The business has been around for 20 years and some dieters do report positive results, but we feel uncomfortable giving our support because of the lack of clinical support and potential for side effects. Plus, it bothers us that the bottle only contains 22.5 servings.

If the time has come to shed off the extra weight, our suggestion is to find a supplement that contains clinically supported ingredients, with no known side effects offered at a price you can afford.

Among the best products we’ve found in 2016 is one called Leptigen. The ingredients are a proprietary blend with published scientific research to spur metabolism and boost fat loss. Dieter’s aren’t talking about negative side effects and users report seeing great results.

Also, the company that makes Leptigen is so confident in the formula they’re offering a Special Trial Offer, which we like.

How Does Synedrex Compare?

Previous Synedrex Review (Updated July 9, 2014):

What You Should Know

Click Here To See Our Highest Rated Review

Synedrex is a pill form diet supplement that is advertised to help dieters shed fat and water weight by controlling food cravings. This diet pill is also supposed to give dieters an endless supply of energy, block carbohydrates and help to curb food cravings. Synedrex is manufactured and marketed by the company Metabolic Nutrition. The company unfortunately has an unpleasing BBB rating. Looking at the ingredients one can see that there are some fat burners on the list; both green tea and garcinia cambogia are well known fat burners that have been shown in some studies to produce results. There does seem to be some disparity among websites that claim this product does not work as well due to insufficient amounts of these fat burners.

List of Ingredients

Chromium, caffeine anhydrous, green tea extract, garcinia cambogia, l-tyrosine, l-carnitine, HPMC, cocoa extract, 5-HTP, and jojoba bean.

Product Features

Synedrex is a diet pill that is advertised to give energy, block carbohydrates, raise metabolism and help dieters to lose extra pounds. Identical claims are made by Plexus Block. Dieters are instructed to take one or two capsules twice daily. On average the product carries a hefty price tag of $50 or more for a bottle of 90 capsules. If an individual two capsules twice daily as the label suggests the 90 capsules will last less than a month.

Advantages

  • Synedrex does have added vitamins and minerals in addition to the fat burning ingredients.
  • The website has nutritional information and other diet related information as well as supplements.
  • The website also contains customer reviews and testimonials.

Disadvantages

  • Synedrex contains copious amounts of caffeine with over 350 mg per dose. This large amount has been known to cause serious jitters, agitation and dehydration when taken over time.
  • At over $50 per bottle on average, this is one of the more expensive diet pills on the market.
  • There is no real diet plan or exercise plan included on their official site, just the pills to be taken along with a health and fitness plan of the dieter’s choosing.
  • Once dieters stop taking the pills, there is the chance that weight could return since there was not a learned modification to eating and lifestyle habits.

Conclusion

Synedrex does have many customer reviews and seems to help some dieters to achieve results. It is suggested, as with all diet pills, that users follow a sensible eating and exercise plan to achieve the best results. Overall this looks to be an average diet pill with a very large amount of caffeine in addition to other energy substances. Synedrex is almost like an energy drink in pill form and as such will pose the risks of the same side effects such as agitation, jitters and insomnia as well as dehydration. Read up on Synedrex Side Effects. Similar side effects are often reported with uncertain doses of stimulants like with Adaptogen or Absolute Nutrition Garcinia Cambogia. While the product may provide results it is important to remember that there are much less expensive ways to get caffeine.

Synedrex Ingredients:

We researched Synedrex ingredients in order to give you the information you need.

Methylxanthine

Methylxanthine, also known as xanthine, is a chemical found naturally in body tissues and fluids.

What Is It Supposed To Do?

The main purpose of methylxanthine is increasing alertness in the nervous system, although it may also help asthma.

Clinical Research

According to a study published in Canadian Journal of Applied Physiology, “The effects of ephedrine, in conjunction with methylxanthines and aspirin, in humans appear unequivocal but include various cardiovascular side effects. None of these compounds have been tested for their effectiveness or safety over prolonged periods of time.”

You may want to try Leptigen, which has clinically tested ingredients.

Sulbutiamine

Sulbutiamine is a chemical containing two thiamine molecules. It is thought to be found in the brain.

What Is It Supposed To Do?

Not to be confused with sibutramine, an appetite suppressant, sulbutiamine is a compound used for memory, fatigue, and the health of the nervous system.

Clinical Research

According to information published by the American Society of Health System Pharmacists, “Although thiamine has not been shown by well-controlled trials to have any therapeutic value, the drug has been used for the management of poor appetite, ulcerative colitis, chronic diarrhea, other GI disorders, and the cerebella syndrome.”

Sandalwood Extract

Also known as East Indian sandalwood, the sandalwood tree, where the sandalwood extract is derived from, is not easy to grow due to the specific conditions it needs for proper cultivation.

What Is It Supposed To Do?

Sandalwood extract is used traditionally for aromatherapy, spiritual use, and commercially for perfumes.

Clinical Research

In a study published Phytotherapy Research, researchers concluded about sandalwood extract that, “However, until further studies are conducted to determine safety regarding internal use, this herb warrants caution with use.”

Yohimbe

Yohimbe is a tree found in Africa. The bark is used to make medicines.

What Is It Supposed To Do?

Yohimbe has been used for a wide variety of treatment, including erectile dysfunction, depression, athletic performance, weight-loss, high blood pressure, and much more.

Clinical Research

In a study published in Research in Sports Medicine, researchers studied the effects of yohimbe on athletes. In conclusion, “Nonetheless, yohimbine supplementation appears to be suitable as a fat loss strategy in elite athletes.” This does not hold promising results for those who are not at this level of exercise.

Is There Anything Out There That TRULY Works?

Before you give up on weight-loss, we suggest you try the Special Trial Offer from Leptigen. They have clinically-tested ingredients and consistently positive customer reviews. Click here to try out the supplement.

    You can take up to two capsules a day, though you may want to start with one according to the directions before breakfast. A vegetable based diet is good but may be hard to stick to. Try to switch it up.

    I started this week on Monday…I felt awful all day and had trouble going to sleep. It suppressed my appetite but that is because I felt as though I was on the verge of vomiting all day. I skipped the second day so today is my 3rd day and 2nd pill and I feel terrible again. I have been feeling sick to my stomach all day. I like that my appetite is suppressed, but I DO NOT like feeling sick all day. This feeling is terrible and I am not sure if it is worth it. My friend is taking these and she gave me 4 to try and see how I do on them…I do not think I am going to purchase a bottle because the side effects are to much for me. My friend said she felt bad but started feeling better after day 5, but I do not want to suffer for 3 more days feeling like this. I will have to try something else.

    It made me feel that same way at first. After I tried “sandwiching” it between food. (Eating a little, taking the supplement, and then eating a little more) The stomach ache went away!

    I’m fascinated by the comments that I read though the effects are real, I sampled to try to find a solution. First of all this product although a weight loss supplement, isn’t designed for those who don’t exert themselves in the gym, no consume a greater amount of water, who may have a weak heart, high blood pressure, diabetes etc. Here’s the solution to the side effects. #1. I purposefully took 2 pills to see the results and yes every side effect was absolutely present. So if this is the effect of taking too much for my body mass and health condition then number 2 should be your choice. #2 I had taken 1 pill for one entire week with zero side effects drinking a decent amount of water and a bite of food. I had an unheard amount of energy that I appreciated very much. So to the solution, #3. Take one half of the daily recommended amount to see what your effects are if any and then begin to modify or increase to a full pill. I will confess that one of the great results was that I spend 3 hours Monday-Friday in the gym so my body was used to working out. All this amazing product has done with the proper dose, has enhanced my overall gym experience to the maximum!

    Ok so I’m sure I’m not the only oerson having penile problems with this product. The negative, it’s hard to stay erect. It seems to effect my testicles either enlarging one or shrinking the sack to the point of where my testicles move around which is weird and painful. Burning urination that can make you feel like you have an std…….. Maybe it’s an allergic reaction to me. I’m not being oerverted or funny. This has happened both times I used it. I wish the original oxyelite was still being made. If you have any questions or you can relate feel free to email me

    Ive been taking these for a year now on and off. They are wonderful but they are very strong. They come in a case that allows you to dump some out which Is what I would do your first time. Dump about a quarter until your body gets used to it. These aren’t for everyone especially if you have a weak stomach. But they do work. I haven’t been exercising so ive only lost about 15 pounds on and off. But they DO CURB HUNGER like a beast. They do make you jittery and sweaty because its speeding up your metabolism. I know when I first started taking them I couldn’t sleep because I was wired but im used to it now. Im actually going to start using both this product and their phenolox product together. Don’t be scared they do work just very strong! you are welcome!

    I started using Synedrex on the 1st of February and it’s damn awesome. At the beginning I was taking half of a cap so that my body could get used to it and after 1,5 week I went for a full cap. It works great but you have to drink a lot of water. I’ve ignored that warning and believe me that waking up with your head spinning and vomiting for few hours wasn’t cool. Apart from that I can’t say any bad things about the Synedrex. I’ve lost nearly 7 kilograms in 29 days and I feel good.

    The last article seems accurate, I got slimmer the first week, I do moderate training everyday, no more than an hour, i run 30-50 bleachers three times a week, my lower stomach and waist went nuts(thinner) in no time, I eat any where from 1,000-1,400 a day some days less, consistently my meals are at least two slim fast, with 20grams of protein per shake, and I have the regular(usually drink whichever). Definition came really fast! It does give me a ton of energy! Too much!!! But I do use the energy, I workout about an hour after taking the pill(one pill a day, sometimes every other day) yes it is hard to sleep but I will catch up! So no biggie, it’s worth it to me.

I have NO side effect at all other than ZERO food cravings! We do drink lots of water to keep hydrated. This pill must be taken as soon as you wake in the AM to avoid insomnia. According to my man, there is no penile issues and he likes the way the pill makes him feel during sex. Five stars for that! LOL

    First day of Synedrex i did not eat before i took it and it DID make me feel shakey until after i ate. the rest of the days i took it i ate before and had several SMALL meals throughout the day and had no adverse side effects. it gave me energy and made me want to work out or do something besides lay in bed. i had no trouble sleeping if i took the pill in the morning around or before 10.
    i have had 2 friends take this and had great results without changing diet or exercise. They recommended taking 1 pill a day for 3 days straight and then resting one day then taking 3 days and resting. for a week and a half and lost 5-10 lbs and kept it off.
    i have had great results so far but you need to keep hydrated and not go on an empty stomach.

    1. Apparently the majority of users missed the word: SUPPLEMENT. A person should ALREADY have excellent training protocols and a excellent eating/nutrition program. 2. If you are losing more than 2lbs weekly, it’s water, NOT FAT. 3. Taking a full dose the very first day is NOT recommended. It is recommended to work slowly to full dose. 4. The ab belt DOES NOT replace a gym session EVER. 4. List the ingredients of your “recommended” product please. The amounts used are not even clinical doses.

    ive only been taking this for 2 days. Just the normal effects that any Energy pillbut to those of you saying that you feeling nauseated or really jittery just with any guy journey as a nutritionist key and I would recommend taking it with food. Something with Substance but still healthy. Favorite is a Egg whites and turkey bacon and a slice of whole toast I think that should help with nausea The misconception with dieters is the diet pill is supposed to be the main souce if their weight-loss. If used properly diet pill should only aid to your weight-loss not sure it should not be the main ingredients.nutrition and exercise should be the main reason so that it helps you keep the weight off when you stop taking the diet supplement

AND IF YOU HAVE NO INTENTIONS OF CHANGING YOUR EATING HABBITS AND EXCERCISE, I DONT THINK YOU SHOULD WAISTE YOUR TIME OR MONEY. OTHER THAN THAT IF YOU ARE LOOKING TO SHED THOSE LAST 10-15 AND GET LEAN WITH MORE DEFINITION, THIS IS A GREAT PRODUCT!!!

    So I’ve been taking synedrex for about two weeks and a half, and I’ve lost 4 inches of my waist (I don’t know how many pounds because I don’t have a scale) I’m not working out and I’ve been trying to eat clean but I haven’t been perfect on it.
    Side effects that I have are fast heart rate, I’ve been going to the bathroom like 2 a week so I have to take laxatives and I drink about a gallon of water a day. But I can say I feel great, lots of energy and I feel happy.

    I am just curious if anyone experienced nausea and dizziness (no vomiting) and if you continued taking the product did it go away. I drink a lot for water and I take my pill during my breakfast.
    The energy is great but I feel light headed and dizzy (especially, during a workout. If it’s something my body will get used to, then I’ll continue but if I’m going to feel this crappy every time then I certainly will not continue to take it.

    Thanks

    So i took synedrex years ago and i lost 60 pounds.
    This year i gain like 30 pounds so and my vacation in December is coming so I needed to take this again.
    This is my fifth day taking it and I lost 5 pounds. I feel amazing and the side effects aren’t that bad. I have cramps, dry mouth (I like it), my neck hurts sometimes but its ok.
    I smoke weed before going to bed so no problem trying to sleep.
    I will come back in a couple of months before my vacation to tell you guys how much I lost.

    This stuff is CRAZY!!! Never had more energy….probably too much. It definitely suppresses your appetite but I feel very jittery. Would not recommend if you are sensitive to caffeine….guess I am. Make me feel “not normal” and nauseated/dizzy. Probably not going to take it again. I would recommend it only be taken if you plan on doing an Iron-Man Triathlon.

    I have been taking both the synadrax and the hydravax, I started taking them on July 9th Iv been taking them in the morning and I drink about a gallon to two a day but I also work out side all day long. It has been 4 days I have lost 7 pounds and I work out and for about and hour in half then run for about an hour. I felt jittery the first morning for about 15 mins but after that I have not had any problems I do eat it with some wheat bread and about a bottle of water. And I do not have any problems with sex I actually see my stamina lasting a lot longer and my heart rate only gets higher when I run. It has been working so far. But I do say to take the hydravax with it. It’s not worth it without it.

    I bought my synedrex from nutrition depot 4 days ago , first day was amazing , though i ate abit yet my stomach kept playing games with me as if i was on the urge of vomiting yet i came through it fine, i was energetic the whole day , but today was the worst to me i took synedrex and waited till it kicks in and then after that i drank my Pre-workout , all i can say is im having unlimited energy i worked out for an hour and half, was heavily dizzy and hands were tingly and numb that has never happened before, now im having fast heartbeats, yes i lost in 3 days and 2 days of working out properly i emphasize the PROPERLY and ended up losing 6 lbs , but i dont think it is worth it especially with the uncomfortness that im having right now i took it at 7 pm now its almost 6 pm and i still can’t sit and relax my body is Cold even though no AC. the funny part i thought i was dying lol but you know your mind plays tricks , though take it easy on synedrex would recommend taking it one a day and then cycling it off for 2 days dont over stress your body , you want change and weight loss go out and achieve it dont play with your body like that.

    A little bit about myself before i say anything for 1 i have a very high tolerance for anything i take and before the fda banned ephedra from xenadrine i was back in the market looking for the next best thing and let me tell you if i can gather all the money i spent on diet pills that promise appetite control and energy and if anything a lot of them made me more hungry i found myself very sluggy without any want to do anything.., 2 yrs later i just so happen to walk into a veggie protein smoothie king here in my hometown and the gentlemen there gave me a sample of this synedrine only after i told him my story and my high tolerance and so forth and he told me “trust me i am the same way i take these myself i only take one in the morning and that is it “. he was not a little guy neither he was quit big i said that is b.s he noticed the facial expression i gave him and he gave me a sample because it is 58.00 for 90 caps i said uhm no so i take this sample hime and thinking of my passed experience i read it and it did say 1-2 caps so i took both caps and boy let me just say hands down this is just as good or even maybe better than my old original xenadrine before the modification.., side affects i will only take the 1 cap 2 is not necessary the only thing i did not care for was the nausea “yuck” 🙁 but after drinking some water and multigrain crackers it went away then i was hot stood under my a.c vent lol at 60degrees i will definitely spend the money on this product i wish i discovered this sooner i would already be at my desired weight.., i had so much energy and no desire to eat so i ate fruit for it was light and not so heavy water most of the day and a light dinner exercise alone was not enough it actually boosted my estrogen my husband was very excited about that and i had extra energy to complete the little tasks around my house that never got done love this product i just hope that some nincompoop does not o.d on this product and tries to get it off the market like my xenadrines all in all in a nutshell if you are looking for a product to boost energy mood and everything else this is the only pill that will give you everything you want and some just heed the warning 1 pill and if you are supersensitive to caffeine i recommend 1 pill every other day otherwise enjoy i am on my way and i LOVE IT THANK YOU SYNEDREX 🙂 5 stars cause there is not a 10 star rating

    After visiting a local nutrition store, the clerk suggested I try Synedrex as it was one of their most popular items. I was given 3 sample packs each containing 2 pills. The first day was rough as far as side effects. Within 20 minutes, the effects were very noticeable and intense. I had to force myself to eat breakfast as the appetite suppression was almost immediate upon taking effect. The next few days were not as intense and built up a tolerance. I found myself with consistent energy, focus and in a good mood. After my samples ran out I bought a bottle of it a week later. The first day of taking it again was typical to the 2nd and 3rd days of taking the samples. Taking day 2 from the bottle was a different story. I experienced the severe niacin flush within 15-30 minutes. I felt as if my arms and head were literally on fire. The effects were even more intense than the first day of taking the samples. I have not altered my strict diet or exercise routine during all this time. It makes me wonder if there are inconsistencies with the formulation from pill to pill or bottle to botle. For the first 3 hours after the niacin flush, the effects were very intense but began to taper off. The key is to fight through it, stay calm and drink plenty of water. Too many people go into self induced panic attacks and end of hospitalized from the effects. You bought the ticket, now take the ride. Overall, I have had a great experience with this as far as results. Synedrex, combined with diet and moderate exercise had resulted in a loss of 15 pounds in less 3 weeks.

    I have been on Synedrex for 2 weeks now. The first day, I had that blood rush to my face deal (red face/ears burning), but it went away within 10 minutes. I have a very sensitive stomach, so I decided to eat before to avoid it. I eat eggs and toast before I take the pill and now I have no blood rush to the face problems. It gives me energy all day. I love it. I lost 20 lbs on OxyElite before they changed the ingredients, 2nd bottle I didn’t lose anything. So I decided to try this, and it seems to be working!

    This stuff works. The side effects of taking one pill were to much. Hot flashes and tremors. My appetite was wiped out all day and had trouble falling asleep. On the 2nd day I carefully opened the capsule and dumped out a 1/3 of the contents, put capsule back together and it was still a little to strong. The 4th day I removed half and took it after lunch. It worked perfect!! No side effects and controlled my appetite until bedtime. I can not fathom how anyone can handle 2 of these pills in a day???

    This product is great…but great as it sounds, the last batch that was made is quite alarming when it comes down to the side effects of niacin flush. Calm down! Don’t panic! It will come to pass. If this does happen, get a blanket ready to wrap yourself in, because you will feel the chills later. Drink lots of water to keep the blood pumping. If you want to continue taking this product after having the side effect of niacin flush, I’d suggest taking it every other day, or 1 hour before working out.

    Best luck to everyone!

    i would highly suggest doing what i do…waking up an hour before you have to get up and taking your synedrex with a full glass of water, then going back to sleep. i take all of my pills (allergy, thyroid, pepcid) at the same time with my synedrex. when it is time to get up, i’m awake. and moving. then i have a boiled egg…protein…with coffee or water. that keeps your stomach from getting upset and you are asleep when it kicks in.

    i had no problems with the synedrex. i ran out and tried the phenolox and my arms and legs and face tingled and burned. that was the second day. as with anything, one size does not fit all. i’m going back to the synedrex. if you had that reaction with the synedrex, maybe you won’t have that with the phenolox. synedrex worked well for me as i have a thyroid condition, so exhaustion is something i fight against all the time. i take a stacker xpc i get from walmart an hour before i wake up, so i CAN wake up. around noon i take a synedrex. i’m good the rest of the day and not bouncing off the walls. it’s nice for a change.

    That is the niacin flushing your system. It should pass if you keep taking it on a regular basis. Drink plenty of water, not sodas or caffeine drinks. This is one of the best products I have used to curb appetite. It will give you the jitters, and stomach cramps or nausea. Your shedding water, your body is dehydrating. Drink lots of “water”!! I do not recommend taking this more than once a day and more than a two month cycle. If you goal is to lose weight, you will. Is it worth the side effects, you will have to make your own choice. All the symptoms you all are having is the synedrex doing its job.

    [Reply]

    Jessica

    You just need water and to eat before you take it and you shouldnt have the niacin flush. Try to eat thirty minutes before and drink plenty of water and you will be fine. It happened to me and still does occasionally if I do not eat about 30mins before taking it.

    [Reply]

    If you take a Tylenol with your Synedrex it will calm the flushing from the Niacin down. That’s what I do whenever I take anything that has niacin in it.

    I just took my first pill yesterday and within 20 min my face got hot and bright red and it moved down to my chest. I felt depressed and an emotional all day and was not myself. I had sharp stomach pains and was drinking water all day. It gave me no energy or focus. I just wanted to crawl into a ball and go to bed. I didn’t take a pill today because I did not want to feel like that ever again. Not sure if I will try another pill.

    the combination of ingredients happen to mimic the same effects as an amphetamine contained in medications such as the ADD medication Vyvanse. It does cause mood swings, but you can control it after the first couple of days. Just don’t kill yourself. Your body is probably not used to the blood trying to move like a regular athletes, hence why you’re on the diet. It will feel weird the for a while.

    I have used both Synadrex and Phenolox on 60/off 30 for a couple years and never had any reaction until today. I bought a new bottle of Phenolox and within minutes of taking a pill this morning had the most intense burning and bright red swollen ‘sunburnt’ looking skin. It was awful. It’s somewhat comforting to know this is happening to other people as well. I too LOVE both products but a trip to urgent care is just not worth it.

I started a new bottle because I had finished the previous one; and notice that for the past two days the side effects are worst. maybe 1/2 an hr. after I take it, my body feels like it is on fire and I break out in this terrible rash around my face, arms, & neck.

    This is niacin, it’s not dangerous. You can actually buy it by itself right next to calcium and vitamin C. It’s not a rash or a sunburn or an allergic reaction. It’s blood vessels being flushed to the surface of your skin, hence the dry/tight/itchy feeling. The drug is also a thermogenic-which is why your hot and sweaty, maybe read what your taking before you take it…

    These kind of pills are not for everyone and there are plenty of em out there! But be careful for imitation of anything! And always do your research. From my personal experience thats how i was too when i first tried these pills. Just make sure u eat after 30 mons of taking them and if you think youre sensitive to them take them every other day then eventually take them once early in the morning. It should say all this on the bottle! As far as buying them $100 is way too much!!! It should only be around 45$-50$!!! Try amazon or the actual synedrex web if they have one! Just be careful -once again!! Do not buy imitation ones

    I have took 2 cycles of synedrex and am currently on my 3rd every time I take the pills for 6 weeks and I take 2 a day bc strangely enough they make me sleepy not hyper. The issues with getting an erection and size is true. As stated above the caffeine tightens blood vessels and other ingredients that help suppress your appetite have hormonal effects making you want to have sex yet have no sex drive. The effects typically take about 2-3 days of not taking the pills to wear off and for stuff to go back to normal. Lastly the tightening of the blood vessels as well as prostate side effects cause you to feel like you have to be constantly and make you have to push to urinate and make the urine and sometimes you will be done urinating and go to put your member away and you will leak bc you haven’t been able to properly drain all the urine out. Crazy side effects but product does work and no side effects seem to be permanent.

    Caffeine causes the blood vessels to tighten. This constriction can prevent the proper flow of blood to the penis when a man is sexually aroused. The effects of – caffeinated drinks and foods, such as coffee, soda and chocolate, can last up to 12 hours. I have been taking Synedrex for about a week and the above holds true until it wears off. But, on the upside I have more stamina and NO problems with performance after the effects wear off! Just my opinion.

    Following the directions to take early in the morning was a horrible idea. I vomited throughout the day. I took the second pill after breakfast the following month, hoping that would have made a difference. It didn’t in my case. I should have known better though- I do have acid reflux issues.

    This product is amazing. I’ve been taking it for 5 days and lost 16lbs. I’ve been working out twice a day for (cardio in the morning , lift in the afternoon) 45 min and eating healthy. The first day I was a little dehydrated, but after that no problems. I guess it just depends on your caffeine tolorince. Tons of energy and no crash what so ever. I take it every morning at 7:00 and 20 min later I feel like I could run a marathon. My bench has also increased dramatically.

    I have been taking synedrex on and off for over a year now. I started last feb after I had my baby with oxyelite pro. No results at all. I had a gym friend recommend this and within a week I noticed a big difference. I do work out with it. I eat in the mornings, maybe some egg whites and wheat toast, eat a light lunch, then by the end of the day it’s worn off and I eat again. I am 5’5 and before i got pregant i stayed around 135 – 140.at the end of my pregnancy I was 165 and a year post pregnancy with the help of synedrex I stay around 122. Love the results.

    This stuff is great. I ordered a sample pack of Thyrene, Synedrex, and Phenolox. Each with 2 pills. Basically to see how my body reacted to them. Tried the Thyrene, and nothing. Skipped a day, then tried the Synedrex. Holy crap. I was a hardcore caffeine addict and routine energy drink consumer. I quit the drinks about a month ago when I tried to get serious about dropping baby weight. These pills are insane with the energy, I feel like I have in the past when I had overdosed on caffeine. (it can happen) The amazing part is I have always said I wanted the kind of energy my kids have, and this is it! Also down 4 lbs from yesterday, assuming it was water weight, but happy with it none the less!

    First day I took Synedrex felt like they should have labeled it Thermo-Nuclear. I was go go go. Second day is a lot better, more normal feeling. I did get a very small touch of nausea when working out in the AM. I take it on an empty stomach along with my other supplements, Osteo Biflex, cinnamon, flax seed oil, aleve. I just started working out in the AM instead of PM so it could be anything.

    whoa- this stuff is basically speed! on 2nd day, and seems to be doing everything it says it will. I take it in morning and feel the biggest rush maybe an hour or 2 later, but effects last all day. I didn’t have trouble sleeping. Yesterday I came home after work and scrubbed my grout with a toothbrush– it’s that kind of high! I think i will only take it a few times a week. Important to drink lots of water. I don’t feel urge to “mindlessly” eat, but i have been eating solid, healthy foods to support my metabolic needs.

    Lol me too! I can’t stop moving when I’m on these pills! I just spent 3 hours bleaching and scrubing my house! It’s like speed, but I do feel jittery because I’m not used to caffeine. I don’t drink soda or coffee so my body is on overload. Do you feel lightheaded at all?

    Started Synedrex on Monday and decided to take every other day. So, I’m on my fifth day,have only taken 3 pills thus far and am down 4lbs.

    I am taking every other morning on an empty stomach. First day was very jittery and could feel the energy tingle out my fingers within the hour of taking. With each pill, the jitters have subsided a bit and by 3rd pill there were no tingly feelings.
    I noticed absolutely no hunger pains or cravings the days I take the pill and very little on the days not taking it. I am now very thirsty and drink tons of water.
    I have not worked out yet but plan to start doing so next week.

    I have been on synedrex for exactly one week now. So far, I’ve lost 4.5 lbs. I am a fitness instructor on the side and get plenty of cardio in, lift weights as well 2-3 X week. I am amazed at how my body looks! I have a cruise coming up and want to look crazy good in my swimsuit.
    I started off with 1/2 a capsule mixed in some juice. Felt awake and ready to go. Definitely get jittery if I don’t eat a little with it. Very strong appetite suppressant, I had to force myself to eat lunch most of this week. I have moved on to one whole capsule within 45 minutes of waking. I do find myself having a hard time falling asleep, but when I do, I’m out!
    My day job has me sitting at a desk mostly all day and I have found that now I stand a lot at my desk and move around more because I feel the need to just move.
    STAY HYDRATED!!! Make yes to drink lots of fluids or yoi’ll find yourself with headaches and body aches.

    I am 28 years old and in good athletic condition. I work out regularly and have taken a few supplements in the process to help me out. I started using Synedrex last Sunday. It was working great;it gave me plenty of energy and curbed my appetite to where I didnt even get hungry and had to force myself to eat. On the fifth day I started getting horrible nausea and tingling in my extremities especially in my hands and my heart felt like it was constantly beating out of my chest. I used the prescribed dose only one pill a day after breakfast. I never had any trouble until the fifth day. I took it the same way on the sixth and within 3 or 4 hours I was having bad side effects. My pulse was raising from low 80’s to 130’s suddenly and my blood pressure was shooting up at the same time. It would come and go. It got to where I couldn’t breathe and was unable to stand up. I even passed out a few times. I was taken to the emergency room just for to be cautious. Everything is fine now that I am off of it. It worked great in the beginning but unfortunately its not for me. So please just be careful and if you do start feeling any side effects then please stop using it. My situation could have turned out much worse had I not been around people that knew what to do.

    Yeah, if you don’t eat within 15 minutes you will get really sick. I found that a bowl of oatmeal and a pear worked great.

When I began to do an extensive cardio workout daily that also boosted more loss.

    You’re slowing your metabolism down to shit. Eat 1500 calories a day, evenly over 8 hours and take in no solid food after 6PM. Ephasize lean protiens, leafy greens, and health fats and you’ll shed it. If you want abs stay away from a.b.s. Alchohol. Bread. Sugar

    Wow, Alan. Kinda harsh.
    It is true though, eating less calories wont promote weight loss. I have been on Synedrex for 2 bottles now, with a month break in between and I have had great results. Eat well, keep walking. You need good calories, that’s it. Keep at it. It takes 4 weeks to notice a dfference in yourself, 8 weeks for your spouse to notice and 12 for your friends to notice. Keep it up!

    i dont think some of yall have tried using syndrex… ive been on it for about 2.5 weeks or so and have lost 15lbs. When you are taking syndrex if you eat more than 1000 calories in a day you feel bloated as crap. I usually only take in around 750 on days I take it and that includes drinking cranberry juice. Seriously, how do yall figure 45 minutes of WALKING is TOO MUCH cardio?!? I go to the gym 4 times a week, lift weights for about 1.5 hours and do 30-45 minutes of running on the eliptical. Lastly, I usually take the pill m-f and take off on the weekends and eat a nice meal on saturday and sunday. This will make you gain a couple lbs from the water your body is now retaining since syndrex eliminates water weight, also will promote speeding up metabolism. So basically I have been losing about 5-7 lbs from m-w then start to level off, gain about 2-3 lbs over the weekend, then 5-7 again m-w so avg around 3-5 loss per week. been working for me so far. ALSO note, weight loss is always going to depend on eating habits, exercise, how overweight you already are or arent. I plan on only taking until I finish the bottle to speed up weight loss to where I want to be and then just maintaining weight.
