Rating: 4.5 (out of 5)

Welcome to this review of the Stoppani Supplement Science Shred JYM fat loss exercise product. This product, as developed by the well respected Dr. Jim Stoppani, is designed to facilitate fat loss in bodybuilders. But does it work? That’s what this review is all about. This review will cover ingredients, manufacturing, product quality, product guarantee, customer reviews and whether or not it works. (You can read more bodybuilding supplement product reviews here within this site.)

Let’s now get into the nuances of this product.

Shred Jym Features & Benefits

Let’s first talk about product quality. While this product appears to have been designed after rigorous clinical research by Dr. Jim Stoppani, PhD, there is a potential negative here. Supplement fraud used to be utterly rampant in the supplement industry, but in the past 10 to 15 years, strides have been taken to remedy that.

One of those is ensuring the manufacturing operations are registered under the NSF International, The Public Health and Safety Company, Good Manufacturing Practices (GMP) Program. Companies that do this successfully complete an audit that certifies products and standards for dietary supplements. These standards cover product manufacturing but also bottling, the non-inclusion of banned substances, raw product purity, even employee training. This certification is also an ongoing certification and is not a one-time thing.

Jim Stoppani, PhDNone of the Stoppani Supplement Science products are made in GMP certified facilities. This is a negative. Does it mean that the JYM product line is inferior? No, not necessarily. Many companies like Optimum Nutrition, BSN, Dymatize and others have this certification. Stoppani Supplement Science is a relatively new company so this may be on the agenda to achieve, but for now, as of this writing, they do not have it.  Jim Stoppani, PhD is the founder and CEO of this company and says he designs all of its products from the ground up. (Stoppani is the well regarded author of “Jim Stoppani’s Encyclopedia of Muscle & Strength” and is a well-regarded expert in the areas of bodybuilding nutrition and strength training.)

Another mitigating factor as to the quality of the JYM products is that a few products have been nominated, in their various categories, for awards from This is a positive. Customer testimonials is another mitigating factor as these Stoppani Supplement Science products are very popular and are growing in that popularity.

So, no, the lack of GMP certification is not a death knell to Jym Supplement Science.

Let’s talk now about the core competencies and capabilities that are being made about this fat loss product.

While this product can be used by generic, amateur fitness enthusiasts, it is designed to be used by weight trainers or bodybuilders. Bodybuilders in particular want to lose adipose tissue (fat cells) that blur muscle definition. Dr. Stoppani says:

Shred JYM attacks body fat from three different angles that all work together to provide you the most effective strategy for cutting body fat. The ingredients in Shred JYM work in synergy with one another to create a 3-stage fat burning system. The ingredients I selected for Shred JYM work to increase the release of fat from the fat cells, help to carry more of that fat into the mitochondria, and increase your metabolic rate to burn up more of that fat.

Furthermore, Stoppani says this product’s specific ingredients allow this three-stage process to occur. Not just the ingredients but their balance and potency will bring about the thermogenesis or fat-loss inducing effect. Stoppani says, “…one ѕеrvіng оf Shrеd JYM рrоvіdеѕ уоu with 2,750 mg оf асtіvе fаt-burnіng ingredients that аrе bасkеd bу science.”

Those three stages, Stoppani says, are: release, transport and burn. So, what are those ingredients? They are:

  • Acetyl-L-Carnitine HCI — 1.5 grams
  • L-Tyrosine — 500 miligrams
  • Green tea leaf extract — 500 miligrams
  • Caffeine anhydrous — 200 milligrams
  • Cayenne pepper extract as Capsimax — 50 miligrams
  • Synephrine as Citrus aurantium fruit extract — 20 miligrams

Its filler and capsule ingredients are gelatin, magnesium stearate, rice flour and silica. In order to understand better this product, let’s now delve more in depth as to what each of these ingredients can do.

  • Acetyl-L-Carnitine HCI — Studies show that ѕuррlеmеntіng wіth саrnіtіnе еnhаnсеѕ fаt burning, nоt juѕt durіng exercise, but also at rest. This particular form of L-Carnitine is better absorbed and can also not only support thermogenesis but also mood enhancement.
  • L-Tyrosine — This nutrient enhances mood but also mental alertness and focus while also providing energy. According to Stoppani, “Thе mаіn wау that tуrоѕіnе ассоmрlіѕhеѕ аll thіѕ іѕ duе tо thе fact thаt іt іѕ uѕеd іn the body tо рrоduсе several important hоrmоnеѕ аnd nеurоtrаnѕmіttеrѕ ѕuсh аѕ dopamine, еріnерhrіnе (аdrеnаlіnе), norepinephrine аnd thуrоіd hоrmоnеѕ. Inсrеаѕеd lеvеlѕ оf these hormones and nеurоtrаnѕmіttеrѕ rаmрѕ you uр, mаkіng уоu more аlеrt and fосuѕеd.”
  • Green tea leaf extract — A popular tea or supplement, it aids fаt lоѕѕ among a large list of other health benefits including a rеduсеd risk оf саnсеr, hеаrt dіѕеаѕе, аnd diabetes. For fitness enthusiasts and bodybuilders, it also may promote enhanced muѕсlе аnd jоіnt recovery, which are essential to bodybuilders.
  • Caffeine anhydrous —     It еnhаnсеs аlеrtnеѕѕ and helps to increase fat loss by supporting calorie burn. Moreover,  it helps to release fat from fat cells and prevent fat storage. Its negative is that it’s addictive and contributes to varicose veins. (Small amounts may mitigate those negatives, though.)
  • Cayenne pepper extract as Capsimax® — Cayenne has many health benefits and is called at by this author, “the king of the herbs.” It is magnificent for the heart grapefruitand all blood vessels, promotes fat loss, and has anti-aging ability due to its antioxidant activity.
  • Synephrine as Citrus aurantium fruit extract — Sуnреhrіnе is the асtіvе іngrеdіеnt іn the рlаnt Cіtruѕ аurаntіum, more commonly knоwn аѕ bіttеr оrаngе. It increases metabolic rate while аlѕо decreasing appetite.  Advantra Z® іѕ a patented fоrm оf Citrus аurаntіum extract thаt dеlіvеrѕ a precise аnd potent dose оf synephrine.

Here is some of the core information elements regarding the product:

  • Serving size: 4 capsules
  • Servings per container: 60
  • There is no powder option; it is available only in capsules at this point in time
  • This product is produced іn a facility that аlѕо рrосеѕѕеѕ peanuts, eggs, wheat and cow’s milk

Side Effects of Shred JYM

There are no reported side effects of this fat loss supplement product. However, one of its ingredients can cause potential side effects, namely, cayenne but as the amounts are small in the Jym Shred formula, it should not do so. The cayenne pepper extract is a whopping 300,000 SHU (Scoville Heat Units) and if taken in the powder form and not in the extract form, it has an emetic (vomit-inducing) effect. By comparison, most grocery store cayenne is not only irradiated but also comes in at 35,000 to 40,000 SHUs. Generally speaking, this formula should not produce any side effects, and currently, reviews on it do not mention any.

A 9.1 score is certainly outstanding. Here are a few testimonials taken from those 168 reviews.

I like this product since it tells you whats in it and you can stack it with the other brands. No weird chemicals, just pure elements on the right dose. 4 capsules, 2 times a day for maximum performance. Avoid after 4pm to avoid insomnia. No jitters, no crash, no blurry sight with this product. You will feel some heat and some sweating with this meaning is working. As with any other product, strict diet and a workout program is required in order to work properly.

Great product! I appreciate the formula combining the needed ingredients to burn fat, provide energy and alleviate the need to take many different capsules. Thanks Jim!

I love this product. I’ve seen results that I expected without the crazy jitters. Helps me with minimizing my appetite while burning fat. My work outs have been consistent with use of this product. If you don’t mind taking a bunch of capsules throughout the day, this product is perfect.

l am sure the formula is good. But even with low doses l experience extreme anxiety, dizziness, tachycardia, (although l am a strong coffee addict ! ) and no energy boost at all ! l also suspect it’s been upsetting my Gl tract. So if burners generally make you sick, don’t think this one is any different. Luckily l only bought one bottle.

First off I would never give a product in but I must say in 3 days worth of time I lost 3 pounds without even eating right or working out grant it I had a decent diet but I had a lot of cheating now I’m starting the diet and the product with a great workout plan using the rewired plan from this site and so far I’m feeling good I’m also stacking but just to let you guys know a product when you can lose 3 pounds with cheating on your diet in a matter of 3 days without working out or drinking water properly it’s a great product I plan on continue taking the product but also at the same time continue the stacking with CLA and clear muscle and a good protein regiment anyone who’s looking to shred fat or just reduce a little bit of your body fat percentage this is a perfect product to start I will post more about the product once I complete a full bottle. keep in mind everyone’s body is not the same what’s good for you or me might not be good for another well work for another.

I’ve tried a lot of fat burners. I’ve also been to YouTube to find info as well in my research. I like this product as it does seem to work. I need to test it more thoroughly but so far I’m happy w/ the results.

Where Can I Buy It?

Jym Shred JymYou can buy it here at, but you are free to choose. What’s the verdict? I give this product a 4.5 out of 5.00. I would give it a perfect 5.00 but as it’s not manufactured under strict NSF for Sport GMP guidelines, I cannot do that. Plus, its lack of a product guarantee and the usage of questionable additives is troubling as well. That said, this is undoubtedly a quality product produced by the venerable Dr. Jim Stoppani. It has many laudatory customer testimonials and has a very unique ingredient profile. Its inclusion of a cayenne pepper extract was especially interesting to me (I’m the webmaster of, a very popular website on all things cayenne) as cayenne has numerous therapeutic health benefits. This product is certainly worthy of your consideration. I hope this review of the Shred JYM product has been useful to you.
