Pre JYM Review: Could it Really give Results? 

I have done numerous reviews but few are of supplements like Pre JYM mainly because most of them are of scam websites. I generally warn people of potential scams and how to avoid them. I have known about this supplement for some time but recently someone asked me to do a review on it as they were unsure if they should order. Though I will not tell you whether to order this or not, I can provide you with some useful information and help you decide.

Wat is Pre JYM?

This is a pre-workout supplement developed by Jim Stoppani who has extensive experience with supplementation and working out in general. He is an expert in the field and claims that his combination of ingredients is better than anything else on the market.

The one thing that is repeated in the website is the fact that they provide a full list of ingredients and the doses of each. They have a point there. Most supplements I have reviewed in the past have a proprietary blend which only offers the list of ingredients but does not provide the actual dosage of each ingredient in the supplement. Usually they claim this is done because this blend needs to be kept secret but for the most part, it’s because if they show the dose it will become obvious that the ingredients are well under-dosed, thus making the supplement ineffective. This I agree with an am very happy to see the dose of every ingredient in the supplement.

This supplement is also advertised to have won the Pre-Workout Supplement of the Year in the 2015 Supplement Awards. Seems legit and considering the ingredients found in the supplement I can believe that. What bothers and worries me quite a bit is the warning they have noted which states that the supplement contains chemicals known to cause cancer, birth defects, or reproductive harm. I was unable to pinpoint exactly which ingredient this was but will continue researching it. Still, this is somewhat worrisome.

Ingredients in Pre JYM

What I like about websites like these is they are very open about the ingredients in their supplements. Also, they offer a Supplement Facts which is essential. In addition to this here they provide you with a brief description, and very informative may I add, that tells you how this ingredient works.


  • Creatine Hydrochloride – 2 g – studies suggest that I may boost muscle strength and power all the while boost muscle growth. Also the hydrochloride group helps lower the pH of creatine which helps make it more acidic thus increasing how the body absorbs creatine and prevents issues with the stomach. The combination with hydrochloride makes creatine far more effective. So much so that taking half a dose of Creatine HCL gives the same results as a full dose of creatine alone. This dose of creatine HCL is considered safe and does not have any side effects.  


  • CarnoSyn Beta Alanine – 2 g – research suggests that it helps boost strength and power all the while improving recovery time, endurance and enables fat loss and muscle growth. It will allow you to maintain more power and strength later in the workouts thus allowing you to do more reps and lift more weight. This dose of creatine HCL is considered safe and does not have any side effects.
  • Betaine (Trimethylglycine) – 1.5 g – studies suggest that it may increase NO levels and help regulate cellular fluid volume. This will further promote the muscle pumps and the muscle size. Other studies suggest that it may improve muscle strength and power, boost number of reps and endurance and boost protein synthesis during workouts. It is considered safe with minor side effects.
  • Taurine – 1 g – this amino acid is important for improving endurance and muscle strength and can help boost production of NO. By exercising you deplete taurine levels and taking supplementation of it before workout out will help you improve your workouts. These statements have not been scientifically confirmed though and there is still not enough evidence confirming them. It is considered safe and there are no reports of side effects.
  • N-Acetyl L-Cysteine – 600 mg – cysteine is an amino acid combined with acetyl group which helps stabilize it. This allows the body to absorb it better and thus use it better. It is known to fight fatigue and promote energy while working out. A study found that it can boost exercise duration by 30%. There are some possible side effects though not dangerous.
  • AlphaSize Alpha-Glyceryl Phosphoryl Choline – 300 mg – this naturally occurring compound helps play a critical role in the way the muscles, brain, and nervous system functions. It boosts mood, helps boost focus, overall brain function and reaction time all the while improving the mind-to-muscle connection while you work out. Combining it with caffeine, Huperzine A, and L-Tyrosine it will boost mental focus and stimulation. Other research suggests that it may support power, endurance, and muscle strength. Though it is considered safe it is important to note that there are possible side effects.
  • Citrulline Malate – 6 g – it is converted to arginine almost immediately when taken which is then converted to NO. Actually studies suggest that it is better at boosting arginine in the body than taking arginine itself. Helps boost energy by 35% and increases recovery between exercise by 20%. These of course are not confirmed statements as it is still being researched. It is considered safe with no reported side effects.
  • Beta Vulgaris L (beet root extract) – 500 mg – it is suggested that it may enhance exercise performance and boost endurance, power, and reduce fatigue. It is still being researched though and more evidence is needed to confirm. It is considered safe with no side effects.
  • Branched Chain Amino Acids – 6 g (L-Leucine – 3 g – L-Isoleucine – 1.5 g – L-Valine – 1.5 g) – These all share a common structure and are used directly by the muscles as an energy source. Leucine is considered the most crucial as it helps stimulate muscle growth while Valine blunts fatigue. Interestingly enough one of the side effects is fatigue. Read further into this and other side effects by clicking the link.
  • L-Tyrosine – 1.5 g – this amino acid increases alertness and boosts mental focus, mood, and energy while you work out and even more so when combined with caffeine. It is confirmed to be possibly effective and has several possible side effects.
  • Caffeine Anhydrous – 300 mg – boosts energy, muscle endurance, and muscle strength while you work out. May also be an NO booster. Note that the dose is equivalent to 3 cups of coffee so avoid taking caffeine with it and don’t take it at least a couple of hours before trying to sleep. There are of course numerous side effects of caffeine to match the benefits.
  • Huperzine A – 50 mcg – this club moss extract helps boost brain function and supports mood and focus. When combined with Alpha-GPC it may increase muscle endurance and strength. There is a long list of possible side effects which you may want to look into.
  • Bioperine (Piper Nigrum Fruit Extract) – 5 mg – studies suggest that this exact dose when combined with other ingredients may increase absorption of said ingredients. I found no study to prove this but there are no side effects of this ingredient and it is considered safe.

Overall, most of the ingredients are still being researched. Though they show signs that they may be effective they are certainly not scientifically confirmed. Some do have side effects but nothing significant or dangerous, at least from what I found.

To Buy Pre JYM or Not to Buy Pre JYM?

Pre JYM is available in 20 servings for $35.57 or 30 servings for $47.97 which is a reasonable price and has 3 different flavors. I think that considering the price and the fact that for the most part the ingredients are safe and possibly effective Pre JYM could be a good option, but research it further before you buy and make sure you peak with your doctor first.
