Product Information


JYM Supplement Science
Muscle Growth - Strength - Energy - Mind*

My Guarantee Inside this bottle is decades of supplement research — from the lab and the gym. As a scientist, I have spent years researching ingredients that will produce results. As a gym rat, I have spent years benefiting from that research. Now it’s your turn. Every ingredient in this formula is in a dose used in clinical studies and my own gym to produce significant gains in size, strength and endurance.* I know it works because this is what I take before every one of my workouts. Let it work for you. Hit the JYM!

Check with a qualified healthcare professional before taking this product. Do not use if you are sensitive to caffeine, pregnant or nursing a baby, under 18 years of age, have any known or suspected medical conditions, and/or if you are taking any prescription or OTC medications.

Once tolerance is assessed, take a maximum dose of 1 scoop. To avoid sleeplessness, do not consume within 6 hours of bedtime.

Rainbow sherbet tastes extremely articificial and no matter whether it’s been dissolved for 30 mins or 2 hrs the betaine will not dissolve. This is the only flavor I’ve had this issue with but the last two sips are awful at best.

I would not recommend. I decided to try the black cherry after reading some reviews and totally regret my decision. The black cherry is so awful and when I finally get it all drank my stomach is nauseous and don’t really feel like doing anything other than lying on the couch. Sorry but I wouldn’t waste my money. I haven’t tried any of the other flavors but I’m not going to take the chance after this.

good energy no jitters
After trying many of the advertised products in magazines I found them to cause my heart to race and I felt tingly. Yes they provided energy but Was it good for my body??? After Starting to use Pre Jym 6 months ago I am in love. No more heart racing, no more jitters, and plenty of energy. Yes they work best if you drink them slow but sometimes I don't have the time to so I drink it faster. It still works great. It is just better drinking it slow. Some of the flavors are a little sweet to me but still taste good.

Great product
I like that this pre workout doesn't have the tingling or burning side effects like a lot of other products. I can definitely see the difference in performance when I take JYM

Overall satisfied
I love the product and all that it has to offer it seems to be working well for me. Lots of energy for my workouts. Not the biggest fan of the island punch flavor but Iâ??ve had worse from other brands.
