Shredz is a fat burner from Beyond Genetics Supplements. We searched the official website for the supplement and could not find a detailed ingredient list. We found several references to caffeine, but that cannot be the only ingredient and if it is, how much caffeine is included? We searched a little more and found the supplement listed for sale on Amazon but the Beyond Genetics company. This time around the company includes the ingredient list but there is no amount listed for each ingredient. So, Beyond Genetics is willing to tell you what is in Shredz, but you can’t know how much of each ingredient you are taking. In a market with thousands of fat burners competing for the same dieter – that is not a good marketing tactic.

List of Ingredients


  • Caffeine Anhydrous
  • Green Tea Extract
  • Alpha Lipoic Acid
  • Acetyl L-Carnitine
  • Choline Bitartrate
  • Synephrine HCL
  • Synthetic Guggulsterones
  • Vitamin B5
  • Yohimbine HCL

Product Features

The first and foremost problem we have with Shredz is the fact that we have no idea how much caffeine, green tea extract and other ingredients are in the formula. Caffeine is of particular interest because too much caffeine can cause negative side effects that could lead to hospitalization and long-term side effects. Some stimulant fat burners contain up to 400 mg of caffeine per pill. If the dieter overdoses on caffeine is can cause a heart attack.

We are also a little concerned that the ingredient list is not easy to find on the official website (if it is there at all). We pulled the ingredients in our review from the product sales page on Amazon. There the dieter can find a detailed description, ingredient list and instructions on how to take the supplement. There is also a warning about taking the supplement, including a warning for dieters with psychiatric disease, recurrent headaches or asthma.

  • We found a list of ingredients for Shredz.
  • May increase metabolism and calorie burn.
  • The product is available from an official website.


  • The product reviews for Shredz appear to be fake as none are from verified buyers.
  • There are no ingredient amounts available before buying.
  • Could contain too much caffeine for the average dieter.
  • May cause negative side effects like jitters and nausea.


When a company refuses to tell the dieter how much of each ingredient is included in the formula, the dieter should refuse to buy the supplement. We were able to find a list of ingredients, but not on the official website and not one that told us what we really needed to know – how much caffeine are you giving the dieter?

    How do I get the tea in delta state

    Im 17 and a dancer, I just started their 30 day challange and I am on my 3rd day. The first day I took the pills I had forgotten to eat and that made me very jittery and nauseous. I lost 4 pounds with doing just dance on the first day. With this diet you cant take the supplements with just a salad or something small. Eat a steak!! I know a few of the wwe divas use Shredz and clearly it works for them. Dont just take these pills and sit on your butt. You NEED to move around! So far I LOVE Shredz. I recomend it to a lot of my friends and family. Remember everyones body is different and it going to react a different way.


    Hi kindly which is the best product for waist tone.

    Been taking this about a week…. no energy, no jitters, feel the same. Preworkout drink is nauseating. Wrote them with no reply. I don’t feel any energy – I’m always tired…. i lost about 2 lbs in 3 days and gained 5 in about 5 days. Lost appetite then i get super hungry late at night. .. always thirsty. So… why did i pay to gain weight and get no assistance from them? Oh yeah. To make them money smh

    Today is my first day taking Shredz for women, the fat burner. So far I feel good. I took it with my vita-pack from GNC (energy and metabolism). I felt really good at the gym and have no side effects. I see all these negative reviews about rashes and vomiting. It must vary from person to person. Don’t be discouraged! Just because some people have problems with this product, it doesn’t mean you will too!

    I love this product I started with fat burner. One in the morning to test out how I would react with food. I usually drink a gallon of water everyday. Gives me focused energy and serious pumps at the gym. After about a week I went to one pill in the morning and one at lunch. I absolutely love this product. The only time I’ve ever felt nauseous or with insomnia is if I don’t drink enough water or if I take it too late. I’m getting get results and it’s forcing me to develop a habit of drinking a lot of water.

    I don’t know why everyone is saying such horrible things about the Alpha Stack. Or maybe they have just made some changes. I have been taking it for one week. Yes the first day was rough with jitters. However everyday since has only gotten better. I have continued working out, drinking water and strict diet. I have however continued eating as many super foods (fruits and vegetables) as possible. I feel great and am losing weight. Everyone needs to remember this is NOT a magic pack. You have to actually put in an effort on your side to make it work. This is only to assist with losing the weight.

    I purchased the multivitamin and fat burner for women and they gave me a severe allergic reaction all over my entire body!!!! It set in about 10 mins after I took both (both recommend 2x day). Rash was severe on legs, arms, chest, stomach and face. Only after 2 benadryl and 35 mins did the itch and rash lessen but the heat lingered as well as feeling faint of breath. I DO NOT RECOMMEND YOU PURCHASE! I also didn’t realize they are not FDA approved and had I known that I would have never taken them.

    I tried the apha female stack for the first time today…and about 2hrs later I had my first and hopefully last allergic reaction in my entire life. If my boss hadn’t given me a double dose of Benadryl before taking me to the emergency room I would have gone into epileptic shock and had a seizure before even reaching the clinic. These products can be very harmful and the company is rude and in denial and won’t do anything for those who suffer from this. Now I have to carry epipens with me anywhere I go incase of a flare or a burst of any type of an allergic reaction….great healthy product right?


    What were the symptoms of your initial reaction?

    My wife turned me on to it since some people she new had tried it with good results. The only other diet pill I’ve tried is the old hydroxycut and that used to give me the gitters bad. With Shredz it gives you energy but not like being wired and the results are good not only am I trimming my belt but seems to help with strength too. Im not a big diet pill person but after using shredz for a couple of weeks I’m liking the results.

    I got so jittery from alpha female I switched to RokStak from rokhardbody and beyond happy with the results.

  • 12

    Honestly, i used this to cut down fast for my bikini comp. It helped, but the withdrawal symptoms are serve. If you suffer from anxiety,depression, or dp/dr I would not recommend this product. After with drawling I have major mood swings,increased hunger, racing thoughts, fatigue, and serve depression


    I started taking the suppliments and had so many panic attacks so come off them but I have been so ill past few days feel sick dizzy, panic attacks how long do the withdrawals last ??

  • 13

    I’ve been taking the alpha female stack for about 6 months now. I love it. I work out every day at 5am. I do however cut back on the dosage. I only take one fat burner preworkout and then one with lunch. Also only one creazine a day also preworkout. I used to not be able to make it through the work day without passing out but now I’ve got energy all day and I go home and just keep going. Highly recommend. Just play around with the dosages and find what works for you.

    Have seen great results and have not had any side effects. Follow the label and have it with a meal not a salad!

  • 15

    I have been taking Shredz for a few months now and I have not had any negative side effects from it. I only take one vitamin a day and one fat burner/creazine with breakfast and before a workout. I don’t feel jittery and alternate 30 days on/off with the creazine. With any supplement I have always started off under the recommended amount and build up so it doesn’t all come as a shock. Like I said earlier, no negative side effects so far. Some things work for people and some don’t. Hope this helps.

  • 16

    Ordered the fat burner & had to stop taking them after 2 weeks cause I always felt naseous & felt like I was going to pass out. I followed directions & drank plently of water (that’s all I drink ). I would not reccomend. Waste of $50.00

    I started taking taking alpha male from shredz, and in a week I started seeing improvement in my workouts. Really love the product.

    I just bought the Shredz Fatburner for her. Its been a week, I found myself with more energy and I was able to push throught my workouts harder then usual. I do not feel the jitters, I still drink one cup of coffee in the mornings. The first night I did have a hard time falling asleep, what usually takes me 15 min to pass out I was maybe laying around 45 min before I passed out. After a few days I was back to a normal sleep pattern. I haven’t noticed any weightloss yet, but probably because I didnt give it enough time. Just wanted to comment on how this product makes me feel.

    I started taking the alpha female stack 4 days ago. The first day, I took the recommended amount of each supplement. I felt extremely jittery and like my eyes were going to pop out of my head. I also could not fall asleep the first night. I decided to only take 2 creazine per day instead of the recommended 4 pills a day. I still felt like something was wrong. In fact, I felt like I was going to pass out from it today.
    I must say that even though I feel leaner, it’s not worth the awful feeling I get from taking this product. I have decided to stop taking it. The only good that came out of these 4 days, is that I have been drinking a TON of water!! I just feel like I can’t quench my thirst, so I’m just constantly downing my 20 oz water bottle! Can’t believe I just wasted all that money!:(

    My sister emailed them and got a full refund.

    Okay so I bought it on promotion and got the alpha female stack. I train for half/full-marathons and lift already. Diet was so-so

    Okay so first day I tried this I didn’t read the instructions really about waiting 30-60 minutes before working out and taking this thing with food. This thing does dehydrate you. I am a runner and I don’t drink water until my 3rd mile but 14 minutes into running I had to stop because I was going to vomit. Then I drank water and felt amazing.

    I took a few weeks off because I also got sick with the flu…

    But I got back on it…it makes you sweat a lot, and you need to eat healthy to fully benefit from this product.

    Do NOT drink coffee or ANYTHING caffeinated with this product. I got stuck in traffic and was running late and thought I was having a panic attack after having a latte. Drink a LOT of water.

    There must be a LOT of caffeine in this thing.

    Pros? I am seeing results and am super happy with this product.

    Cons? Nausea, can’t drink coffee.

    Please send a complete list of the ingredients, instructions on taking this product and a complete list of side effects and warnings please.

    I’ve been taking it for almost a week and I noticed that my pump is better and the amount of calories and sweat is far greater with here products than others. I’m taking the Alpha Male stack by the way.

  • 23

    I bought the Alpha Female Stack also which includes Shredz for women, Creazine, and Vitamin Z. Usually after about 20 mins of taking the 3 products I get horrible cramps until I begin my workout. I also feel quite nauseous the entire day. I did how ever lose 4 pounds in 3 continuous days of working out which I have never been able to do before. The pills also make me have to pee like a pregnant woman. Swear to God, every 30 mins or less. If I drink anything other than water, it gives you pasty cotton mouth. Don’t know if I want to continue using them or not. I keep getting a low grade fever every time I take them. Has anyone else felt like this? I hoped to find some ingredient that could possibly be making me sick…


    i started them this morning and feel sick to my stomach and been feeling noxious


    yes!!! omg!! i had the STOMACH FLU for Days and a fever!!


    I took it for the first time today….I see have exactly the same symptoms. Cotton mouth, cramps and nausea…

    I started the Alpha Female Stack which includes Shredz for women and their creatine and vitamin z tabs. I felt fine during the day but had horrible insomnia. I stopped for a week then retried the tabs earlier in the day. Didn’t make a difference; still had incomnia. Planning to contact Customer Service on Monday for assistance. I only drink one cup of coffee in the morning. I avoid caffeinated pop so I’m not sure what else to do.

    what are the results from this product like? and what are the side effects?


    noone i know has taken these supplements I am going to try and test them out I will leave a review as soon as i am done. the bottle says take 1 capsule with breakfast and one in the aternoon or take as a preworkout.


    Honestly, I have been taking for a month, it gives me energy for my workouts but it makes me jittery, if I don’t workout right away or don’t eat enough with it, it makes me feel super jittery and I really don’t like it. So I’m pretty sure I will not be ordering it again.

    Besides all that was mentioned above when you go to their website to look at the reviews they don’t upload completely and only show reviews from 2012 if this product was as safe and good as they say they are why don’t they have more reviews and reviews that actually shows what they are saying


    They only go for the money not for the health of there customers, just ignore this company hopefully USAD will knock them out soon.


    Lol it pretty much says do not buy or trust that product. All about money, go to the website and see what the descriptions are for the products thier not even detailed, it’s ashame businesses these days they try to make it look good by the eye but really the product can be harmful and dangerous, all the reviews say insomnia and dehydration not good to have those sideffects at all. People should really ask questions to coustomer service, get specifics out of them that’s what I would do of I were to get it, thier are a lot of better and proven supplements out thier just do your research hope this post helped everyone!
