Performix SST employees, have you ever taken your own product? We decided to take ingredients, side effects, customer service quality and clinical research. There were hundreds of user experiences to scour through. We narrowed down and condensed to give you the info you need.

Performix SST Readers: Click here to find out why we're giving away samples of our product, Dietspotlight Burn.

What is Performix SST?

Firstly, Performix SST is a “super thermogenic” containing caffeine, ashwagandha, bitter orange, synephrine hcl, Huperzine A, yohimbine hcl, mucuna pruriens, Bioperine, medium chain triglycerides and safflower oil. [1] Supposedly, the supplement promotes weight-loss by burning fat and boosting metabolism. The directions say to take two capsules in the morning. The company recommends not using with other caffeine-based products. [2] [3]

The company behind Performix SST was founded in 2005. Purchases can be made through trusted online retailers, but not on the official website. We like that the business has been around for 10 years and that we found some supportive comments, but read on…

Performix SST Side Effects – “Widely Reported?”

The first problem is Performix SST side effects. “If you take the supplement as suggested, you may notice some issues the first time,” said our Research Editor. “Feeling jittery or nauseous is a sign that the product may not be suitable for all users.” [4]

“The first day I took one pill and it gave me a huge energy rush for about half an hour and then dropped for the rest of the day. The second day I tried taking two pills as recommended and I got very jittery,” said one buyer.

Another dieter reported, “My first and last time using this product. I took two pills on an empty stomach around 7:45am, about 30min later I was sweating. When I arrived to work I felt jittery and unable to focus.” [5]

Side effects are rare, so we decided to locate reviews commenting on more positive reactions.

I now love working out in the mornings, and what impressed me was that I felt no jittery side effects,” reported a dieter.

Results – “Not According to Customers”

Another issue we found in Performix SST reviews related to lack of results. “I did not loose any fat or weight that I couldn’t have lost on my own. No significant change for me personally”, reports one user. [6]

Another stated, “I got absolutely nothing out of this product. Complete waste of money.”

While some users didn’t notice results, there were customers talking about their results.

“Recommend for weight loss and a boost of energy. I feel very focused while using this,” said a customer.

This will not make you lose weight by itself. This is a product for over-coming a weight plateau and for people who are cutting fat and water weight,” stated another.

Based upon our research, it takes just one complication, like negative side effects, to thwart chances of long-term results. If SST Performix does cause problems, dieters may not trust it. [7]

The Science – “Legitimate?”

You can easily find clinical research supporting the use of stimulants to increase metabolism, but Performix SST does not bother to list any. Unfortunately, there’s science showing some significant side effects when ingredients, similar to the ones in this formula, are combined with other stimulants. Science is one of the most important aspects for us at DietSpotlight. If Performix SST does not offer positive scientific support, that could be an issue. [8]

The Bottom Line – Does Performix SST Work?

Drum roll please…what’s the deal with this one? Well, we like that Performix SST has been in the business for 10 years and the use off some natural ingredients, but the lack of research connecting it to weight-loss is concerning. We’re also a bit skeptical about it because of customer reviews talking about the lack of results and negative side effects.

If you’d like to melt away those extra pounds, we suggest going with a product that’s not connected to harmful side effects and gives you a list of ingredients supported with published clinical data.

Among the best products we’ve seen this year is our product called Dietspotlight Burn. The supplement is formulated with four clinically-tested ingredients. Results are often found in publications such as The American Journal of Clinical Nutrition.

Also, we’re so confident that you’ll love our supplement that we’re offering a Special Trial Offer, which is a good sign.

Performix SST claims to be a "Super Thermogenic" offering "Ballistic Energy." Most often, this type of language means caffeine, or another stimulant, is the first ingredient in the mix. In this case, that is 100% true. As a matter of fact, there are multiple strong stimulants.

Caffeine [1] is a bitter stimulant that is usually found in coffee, tea, and soda. When consumed in the right amounts, it can have significant health benefits, but in excess, it can cause some negative side effects.

What Is It Supposed To Do?

As a stimulant, caffeine can help boost energy, treat migraines, and aid in mental awareness.

Clinical Research

According to a study published in International Journal of Obesity and Related Metabolic Disorders: Journal of the International Association for the Study of Obesity, “In this 6-month placebo-controlled trial, herbal ephedra/caffeine (90/192 mg/day) promoted body weight and body fat reduction and improved blood lipids without significant adverse events.”

Ashwagandha Extract

Ashwaganda is a plant, and an extract derived from its roots and berries are used in some medicines. It has a very strong smell and is used primarily in Indian, Ayurvedic, and Unani cultures.

What Is It Supposed To Do?

Ashwaganda extract is used to help treat anxiety, insomnia, skin conditions, liver disease, fertility problems, and arthritis.

Clinical Research

According to a study published in the Journal of the International Society of Sports Nutrition, “This study reports that ashwagandha supplementation is associated with significant increases in muscle mass and strength and suggests that ashwagandha supplementation may be useful in conjunction with a resistance training program.” Nothing was said about its ability to aid in thermogenesis. [2]

Bitter Orange

Bitter orange, also known as synephrine, is a plant used as a flavoring agent and an ingredient in supplements. It has become a popular aspect of many weight-loss products.

What Is It Supposed To Do?

Bitter orange is primarily sold under the pretense that it can help aid in weight-loss. However, it is also used to help an upset stomach, gastrointestinal disorders, anemia, diabetes, kidney disease, bladder disease, frostbite, and general pain.

Clinical Research

According to a study published in Journal of Medicine, “Three studies reported increased metabolic rates when ingesting Citrus aurantium products, however, at least two of these studies were acute.”

One that’s on our radar is one called Dietspotlight Burn. It’s backed by science and contains clinically-tested ingredients. Click above to learn more.

Performix SST Side Effects:

In the world of weight-loss supplements, herbal supplements are often mistaken for the option that doesn’t cause negative issues. Every ingredient list has the potential for problems, though often slight. Although Performix SST side effects are relatively rare, that doesn’t mean they don’t exist for some users.


Nausea is a feeling of uneasiness that can be characterized by the need to vomit, though sometimes it does not lead to the action [1]. It is important to consult a physician if it lasts for an extended period.

What causes nausea?

Many different problems can trigger nausea, including pain, motion sickness, infections, food poisoning, heart attacks, and some psychological illnesses. It can also be a common issue with herbal supplements because of their ingredients.

Accelerated Heartbeat

An accelerated heartbeat, also known as tachycardia, it when the heart beats faster than normal. Some symptoms that can be associated with this issue include shortness of breath, chest pain, fainting, lightheadedness, and dizziness.

What causes an accelerated heartbeat?

Medically, an accelerated heartbeat is caused by a disruption in the electrical system of the body. Some outside factors that can cause this include high blood pressure, an overconsumption of alcohol, medication, herbal (stimulant) side effects, exercise, and sometimes, but rarely, heart diseases.


Jitteriness is a “shaky” sensation that can be felt throughout the body.

What causes jitteriness?

Jitteriness can often be caused my caffeine, which can be found in coffee, stimulants, and many herbal supplements. There can also be a connection with anxiety or worry, as well as other psychological triggers.

Shortness of Breath

Shortness of breath is the lack of ability to breath fully, usually including a tightness of the chest, a feeling of suffocation, dizziness, and more.

What causes shortness of breath?

According to the Mayo Clinic, “Your heart and lungs are involved in transporting oxygen to your tissues and removing carbon dioxide, and problems with either of these processes affect your breathing,” which in turn can cause shortness of breath [2]. Other causes include low blood pressure, heart diseases, and pneumonia.

Performix SST side effects are not guaranteed, but some have said they experience nausea, accelerated heartbeat, jitteriness, and shortness of breath. To protect yourself from potential problems, it is always the best idea to consult with your physician before taking any supplement, especially if you’re taking prescription medications, are under 18, have a medical condition of any kind or are pregnant or nursing.



Performix SST contains some stimulants. With these ingredients, there is the likelihood of side effects like jitters, especially if the user is sensitive. Though we rarely found any mention of adverse reactions, there are a few out there.


“Every time I took Performix I would feel nauseous and would just feel sick. I tried to give this product a second, third, and four chances and I would always feel nauseous and sick.”    J. Huitron


“I took 1 pill and felt queasy and anxious all day. I generally don’t have anxiety but I could barely take a deep breath and my heart felt like it was going to burst out of my chest.”    Stephanie


“The first day I took one pill and it gave me a huge energy rush for about half an hour and then dropped for the rest of the day. I saw no change in my appetite. The second day I tried taking two pills as recommended and I got very jittery.”    Veronique


“It may work but even just half the dosage made me feel incredibly shaky and I have a high tolerance.”    Adriana


“I took two pills on an empty stomach around 7:45am, about 30min later I was sweating. When I arrived to work I felt jittery and unable to focus. Around 11am I was shaking to the point where I was unable to write because the shaking was so bad.”    Delarose


“This product did nothing but give me a jittery feeling.”    Laurie


“I took the first dose and started shaking and twitching. It wore off after a while. They make me feel pretty terrible and shaky but not really hungry.”    Kellye


“I took one the first day and it made my head feel a little funny, but it passed after about an hour. No extra energy noted. Took two today and it is definitely doing something!! Stomach queasy, sweating, heart racing, jitters.”    McKinzie


“I took the 2 pills as instructed on the box. after about 2 hours I started to feel shaky and very anxious.”    Bell


“Felt no differences and felt nauseous.”    Eric


“Loved it at First. Then it gave me the worst heart burn ever.”    Kelley


“It is just okay. I noticed that the first time I took it and I was running I felt very out of breath in such a short period of time.”    Corina


“Today I woke up took the two pills and about a half hour later went outside to run. Couldn’t finish 3 miles and I kept having to stop and sit down from nausea and feeling like I was going to puke up my organs. I normally run 5 miles with a slowdown in between.”    Patricia


“It gave me energy I just had to stop taking it is just couldn’t with the nausea that I would get in the morning every time I took it. Made me feel really sick.”    Yvonne


“I took 1 this morning and I’m a nervous wreck. No more for me!”    Deborah


We know that side effects are rare, so one that’s caught our attention is one called Dietspotlight Burn. There’s no mention of harmful adverse reactions and dieters are seeing great results. Want to learn more about it? Click above.

Performix SST Scientific Abstracts:

Caffeine Anhydrous

One of the world’s most common and well liked substances is caffeine. Caffeine’s effect on enhancing physical performance and stamina has been researched for decades. Categorized as a soft stimulant used by athletes for the mere intention of increasing activeness, many studies frequently found that caffeine enhances cardiovascular activity and that the effect on short term high power exercises is less notable. While athletes are not only ones that use caffeine for performance and body structure reasons, there is an absence of research on the effects of caffeine for recreational use. [1]

Ashwagandha Extract

It has been speculated by scientists that ashwagandha has a lot of health enhancing properties that come from its antioxidant steroidal alkaloids and lactones, mostly the withanolides. Performing as an innate adaptogen in the body ashwagandha could battle stress and help with weight loss. Cortisol is a stress hormone in the body that can also promote obesity, it has been reported that ashwagandha has the ability to decrease levels of cortisol up to 26 percent. Antioxidants in ashwagandha could make general health better and encourage the burning of fat. It has been suggested that ashwagandha be used as a supplemental approach for increasing energy and weight loss through the reduction of stress. [2]

Advantra Z

Bitter orange (Advantra Z) has been researched for years, more than 30 scientific studies and reviews back the safety and effectiveness of bitter orange. Through research studies it has been shown that bitter orange or supplements that include bitter orange have a positive effect on metabolic rate, weight loss, and decreasing body fat with no harmful effects. Studies have also found that there bitter orange is safe and does not have a negative effect on heart rate or blood pressure. It has been stated that there have been no reports of harmful effects of bitter orange since 1969. [3]

Synephrine HCL

Synephrine is another form of bitter orange and studies propose that bitter orange boosts the disbursement of energy and fat breakdown as well as it slightly suppressing appetite. Bitter orange has replaced the ingredient ephedra in a lot of products since ephedra was banned by the FDA in 2004. Many studies have been done on bitter orange and its influence on weight loss, but it is difficult to understand results because the bitter orange is most often mixed with other ingredients in weight loss supplements. [4]

Huperzine A Extract

Typically used for Alzheimer’s disease, huperzine A is a Chinese herb extract. Studies have found that it seems to have positive results on the enhancement of mental function and everyday living activities in those with the disease. [5]

Yohimbine HCL

A chemical that is found in yohimbine bark could increase metabolic rate, decrease hunger, and boost fat burning to assist with weight loss. One initial trial did find that yohimbine was not effective for weight loss. A double blind study conducted showed that women taking 5mg of yohimbine four times daily along with a weight loss diet plan lost a considerable amount of weight as compared to those who took a placebo. Another related study found no weight loss advantage of yohimbine compared with a placebo. [6]

How long do I have to wait after taking this product if I want to have a beer?

Victoria (Editor)

Hi! For detailed product and usage instructions, please refer to the Performix SST official website for more information.


Is it safe to take it while being on my period?


Hi Ramya! For detailed product and usage instructions, please refer to the Performix SST official website for more information.


Today my first day!! I hope performix wok !! I


I started this 5 days ago… Im 29 yr old, 5’5″, 177lbs, mother to 3 under 8yrs old and work a full time job. GNC recommended this product to help me boost my weight loss. I was told to take it with a daily vitamin and on an empty stomach. Day 1— took as recommended and boy did I get the boost of energy and also got really hot!!! I pulled the AC down to 60 in my house and was running around cleaning like crazy. I felt great!! About 2 hours later I got a horrible headache and felt very dizzy. The headache lasted off and on all day. I ate my recommended calories in healthy foods, but still it still didnt go away. Day 2— took 1 pill and the vitamin and experienced about the same with the headache and dizzy spells. Day 3— after research I decided to drop the vitamin and just take 1 pill and WOW Im in love!! I feel great during the day at work and have been staying on top of my recommended calorie intake. I haven’t weighed myself yet… Im trying to hold out till the week mark, but I feel a lot better. The boost of energy does fall during the afternoon and during my late afternoon workouts it does seem really hard. I sweat more than ever and get tired a lot faster, but sadly due to my work schedule this is my only time to workout. I would suggest to anyone that is starting this product to start with 1 pill and workout shortly after taking it so that you have the energy. Good luck to all!!


I have purchases it but never started using it; do I take it with water?

Jenny Jasso

We love me and my husband have been taking it since starting it 3 weeks ago we have each lost over 20 pounds with changing our diets and exercising a bit


Performing SST- I’m pretty much your average Joe. In my opinion, it works great for me. I just took my last capsule 2 days ago and I’m out…need more. This product does its job, but you got to stay on top of your workout/diet. As soon as i start my 1hr of cardio/calisthenics, I’m a little more focused and I seriously pour sweat. At the end of my workout, shirt is drenched in sweat. No side effects that I’ve noticed. So far, so good. This is just me though.


I’m on day 3. I am 5’5, 275lbs, and have hypothyroidism and lupus. I am obviously not in the best of shape. Definately hand to mouth disease. I decided to take this product out of curiosity because in the past I’ve tried it all without results. I recently have been trying to educate myself and repair my body with more natural foods, less crap. That by itself is hard after 40yrs of eating unhealthy. I expect side effects even if the sales person said may cause some caffeine related jitteriness. I asked about bathroom issues (yes I have IBS), they said no, no problems. Well so far he was true to his word. I did have to #1 a lot but that’s to be expected if people really thought about what heating up the core means. Plus it made me thirsty. No issues with #2, although I expected to have that problem and didn’t. I made the first day classic mistake of still having a tea in the am and soda with lunch but I honestly didn’t feel jittery at all. My heart didn’t feel like it was pounding either. I did find myself easily bored and wanted to find things to clean or do. I did notice I wasn’t snacking and not as hungry with my meals. But the first night I didn’t sleep. My eyes couldn’t stay open but my body and mind was restless. The next day I was able to go about my day with the same amount of energy and not tired. I did sleep very well the 22nd night though. I know it’s only been 2 days but I got on the scale and no was 4.2 pounds lighter, which could be the amount of water loss, but I’m going to see this through. Today being the third day I have a little heartburn but I can’t blame that on the product. I took this product with hope but no expectations and I will check in again by the end of the month to progress or not. Years of unhealthy habits, I am not one to expect miracles but even miracles need a little help.

Your NameAngela

This is my third day on the Pill pill it turn my stool blue in color same as pill is this normal??

Victoria (Editor)

Hi. Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you were experiencing.

Darius Velasquez

Im 19 years old and ive been trying nuerotropics back and forth for years, when i first bought the product i took two pills on an empty stomach and within 10 minutes got a huge rush of energy and focus. Throughout the day I stayed active and work was a breeze. Ill probably stay withbit

Military female

I’ve been taking performix for 3 weeks now and work out 2-3 times a week due to my schedule. I wouldn’t say it’s that bad, I do feel like my pants are more loose. I don’t feel as bloated, I drink a lot of water/green tea. I use the bathroom a lot (number 1) due to drinking too much water, but that’s a good thing. The only complaint I have is, an hour or so after taking these pills, I get really hungry. Sometimes I feel like I’m starving. However I am 5’0 – 130lbs. I do get the cold sweats 30mins-1hour after taking these pills. I guess we will see what happens after I’m done with the bottle!


I take this and have talked to a diet doctor and the extreme hunger feeling is your metabolism working extra! So, its a GOOD thing. 🙂 ive lost 30 pounds in these things and CLA with it as well works awesome.

Your NameMare

I’ve been taking Performix SST for about 6 months now. At first, it gave me plenty of energy and I HAVE lost 12 pounds. 🙂 However, I’m not feeling the energy that I was when I first started taking it. Is it ok to take 3?

Jesse Joe Springfield

You need to cycle the product. Ether take it 8 weeks on then 2 weeks off or 12 weeks on the 4 weeks off. You will notice you are a lot more tired once you are off them. I was for me at least.

Victoria (Editor)

Hello! For detailed product and usage instructions, please refer to the Performix SST official website for more information.


if you dont follow the instruction it feels bad so must follow what the instruction said..


I went to GNC because I’m 50yrs old now, don’t drink or smoke but have been feeling very fatigued lately. Wanted something for good energy and as I read these reviews I see this stuff is for weight loss, not what I asked for!!!!! Made me very hot, very sweaty, very itchy and today being day 4 I thought I had the flu most of the day!!! A garbage product!!!! Going in this week for a full refund!!


Been taken it for two weak now along with the yellow bottle and going to the gym 6 days a weak. I have lost 12 pounds I have great energy it’s a good product. My only complaint is I have been itching I’m guessing it’s from the niacin should I just use one of the bottles and stead of mixing them .


What time of day did you take it? I’m sorry in school and workout right after, I’ve been taking it in the morning


Hello Charles. All users are different and can experience different side effects. Please refer to the Performix SST official website to learn more.


I’m 36 yrs old, 5’6″ 197 lbs. I started taking performix sst 3 weeks ago with no set routine at the gym. I work a pretty hectic schedule so time is not in my favor. However with performix sst I have the energy and focus all day. I haven’t changed anything in my diet and lost an amazing 14 lbs. I definitely feel the difference and look forward to seeing the end result once I get in the gym. I take mine around 9am with no side effects what so ever and I take them on a empty stomach.

Yourjessica Name

Love it.


Started 8/16/2016. I am 51 years old 5ft9in 161lbs, a soccer player and have a family schedule that is crazy. I have taken other products and had some weird feelings and outcomes. Day one took 2 as directed felt okay not very hungry in any way but not wanting to over eat by the thought of I am on a diet supplement. I am not doing an exercise program with this just my daily routine, meaning playing soccer and walking when I can get it in. Still taking my vitamins and trying to maintain normal for whatever normal is for you personally. So well see what day 2 has in store.


My husband and I have been taking this product for 3 months. His results have been much better since he faithfully goes to the gym and eats very well. In not getting the hang of it and the pounds are dripping off!!! You need to follow the directions. Start with 1 pill a day then try 2 a few weeks later. Don’t just jump to 2 off the bat! I have to eat within 10 minutes of mine or I get sick. I have energy all day and it curbs my appetite. A well balance diet and gym routine paired with this is the key! Don’t go to the gym?… Don’t eat right?… DON’T EXPECT RESULTS!!!!!!


I am taking this product SST glow female thermogenic for a month now.I have a very excellent results.. Lose 7 lbs until my blood pressure go up..so what do you think …is there any ingredients of SST glow that makes my blood pressure up.pls help me I love this product and I still have two bottle stocked.


HI Anna are you still having that issue with your blood pressure

Victoria (Editor)

Hi Mildred. All users are different and can experience different side effects, but we have noticed that users have experienced somewhat similar side effects. Please make sure to consult with your physician before continuing taking this product if you are still having side effects.

Margo Gauthier

I have been in the SST performix Iridium for a little over two months now and love it. I am more focused, I have lost 25 lbs so far. I also do the Syntha-6 edge with the pills too which is a protein shake. I feel amazing and I really need the energy for what I do at home.


I absolutely love the product and the energy that it gives me. My only concern is if it could cause false positive on drug tests as an amphetamine since I’m required to drug test monthly. Any feedback would be greatly appreciated. .

Victoria (Editor)

Hi! For detailed product and usage instructions, please refer to the Perfomix official website for more information.


this product gives me insane amounts of energy and I absolutely love it. My only concern is that it could cause false
Positive on drug tests which I am required to take monthly. Are the ingredients safe to take while being drug test. I would hate to stop taking the product.

Victoria (Editor)

Hi! For detailed product and usage instructions, please refer to the Performix official website for more information.


I think the people who had problem that this product didn’t take it correctly…I mean as I was reading the reciews, none of them said that they go to the gym at all. You can’t just take it and expect results, it’s also meant to be a preworkout, that’s why they feel jittery. So it’s their own damn fault that they had bad experiences. Don’t expect results if you don’t put your own time and effort into it.


I’ve lost 6 lbs in the 8 days on SST. I’m in the gym 4-5 days a week and feel focused for the 1-2 hrs I’m there. Im 28 yrs old, 6’1 260 and plan to get down to 225 in 3 months with SST and a good diet. Feel no side effects at all. I take two pills at 9:00am and eat breakfast at 9:45. I also take the Preformix Super Malet every night before bed. The two products seem like a good combination for my body. Good luck to everyone on the road to weight loss


I have always used hydroxycut products but was recommended Performix at gnc . Returning today due to lack of results and going back to Hydroxycut

Your Nameangela

I don’t have any complaints about the product. I have lost 20 pounds and I also go to the gym 5 days a week. I needed the energy and so far so good.


How long have you been on product?

This is high dose pill expensive too. I hope it will work make my skin glow


Not worth it. Feeling super anxious and jittery. I drink coffee regularly so I thought that the caffeine wouldn’t bug me but it does. Its better just to eat healthy and work out. Taking it back

  Will this fail a drug test ?

I have been taking performix SST for about a month now, and have noticed that my pants feel a bit looser and my stomach is more toned, without me having to change my exercise routine. I do, however get the “cold sweats” some people have mentioned, but isn’t that because it’s a thermogenic? It’s supposed to increase your core temperature and kick start your metabolism…and Craig, I too have ADHD and am taking a medication for that (non stimulant tho) and yes, it makes me jittery, but once i have food in my system, the jitteriness goes away for me.
Overall, I do like the product. My one concern is a drug screen (I just got a full-time job) and the company has been calling me (while I’ve been at work so I was unable to answer). I’m worried that the SST caused me to fail…(keep in mind I havent been able to speak with the person from my company so I don’t know the reason for their call). Does anyone know if failing a drug test is possible due to taking an SST?

There aren’t ingredients in the formula to suggest you would fail your drug test, SZ.


i am also concerned about taking drug tests since I take them monthly, are you certain that this would not cause a false positive as an amphetamine? Thanks

Hi! For detailed product and usage instructions, please refer to the Probioslim official website for more information.

  Highly recommended !

Sst iridium is a phenomenal addition to any strict workout/diet regimen. Sustained energy with zero crash is almost impossible to find. The red (flush) that occurs is your body’s natural response to the B vitamin Niacin, and should only last a few moments. I’d recommend this product to anyone who isn’t hyper sensitive to what is equivalent to a medium sized Starbucks coffee. 10/10

  It works !

Well it definitely works! First day taking it… Super focused, tons of energy. Beware… You won’t feel like eating… At all! Make sure to eat or you’ll end up awake for hours on end like me! Trying to sleep now…. Good luck

  Not feeling well after 2nd dose !

I purchased Performix Iridium SSTI – I have only been taking it for 5 days. I don’t think that I will continue to take them. I am not sensitive to Caffeine at all but these made me shake and I felt cold all day even though I put the heater in my office at the highest setting possible. Also, stomach issues have been a problem. Cramping mostly and just a general feeling of being “off”. I purchased at GNC after consulting with the sales person. Cost of $109 as I purchased the GNC membership to get the discounted rate. Not worth it.


If you didn’t want to feel shake, burn, or have a cold feeling, a thermogenic is probably not for you…


I purchase mines at gnc for 80$ plus membership to get discound and is not worthy stomach pain, nausea, vomiting, shaking,cold , unable toeat because the pain in my stomach was really bad. I took both of my pills with a lean shake of cookies and cream after I spoke with someone at gnc. I will try 2nd day 1 pill to see and will let everyone know.


I bought the product on Wednesday afternoon took first 2 on Thursday morning went to work out and felt the heat throughout my body but my ears got really hot and then it went away. Took it Friday morning went to work out and my ears got hot again and got swollen and still swollen and hot and today is Sunday morning last pills were Friday morning.

  I'm exhausted again
Michelle (Verified User)

i started taking this about 4 days ago and only gives me energy for about 2-3 hours then I’m exhausted again. I constantly have a headache and feel off (sick feeling).
Think I am going to stop taking it as its making me more blah than I was before.

  Never again

DEAR GOD!!! Why am I still awake??? Never again!!! 0/5

   Hopefully, I'll be responding

My hubby bought me the SST Glow (Female Beauty Thermogenic), which I believe was designed for women specifically. I haven’t experienced any of the above reactions and found this product to be great thus far. There’s no bad taste or stinky burp, as I’ve experienced with Hydroxycut and Xenadrine. I have tons of energy and I don’t feel the “sudden drop” that tends to come after your typical high. Once I started the full dose, I did have a few hot sweats which is pretty customary with a fat burner. No vomiting, no breakouts, everything is good so far. Hopefully, I’ll be responding with fat loss soon. (fingers-crossed)

  I wanted this to give me a boost
Mel (Verified User)

Took two pills as advised at 8am, immediately after my ears, elbows, and nose turned bright red and itched! After that I became extremely jittery and nauseous which lasted the entire day. I couldn’t even hold my phone because the shaking was so bad. I wanted this to give me a boost for workouts but I couldn’t even go because the shaking and nausea combined is very overwhelming.


Do not know why people can’t read instructions, my bottle says one in the morning on am empty stomach then I take again at lunch time, no where does it say to take after eating and not 6hrs prior to bed
