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!

Mix 1 scoop of Pre JYM in 12-32 oz. of water and drink 30-45 minutes before workouts. Consider allowing Pre JYM to mix for 10-15 minutes before drinking. Also consider drinking it over the course of 15-30 minutes.
Produced on shared equipment that also produces products that may contain EGG, FISH, MILK, PEANUT, SHELLFISH, SOY, TREE NUTS, and WHEAT.


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. Pre JYM is an incredibly strong pre-workout matrix that contains 300mg caffeine per serving, the equivalent of approximately 3 cups of coffee. Avoid using with any other caffeinated products. Too much caffeine may cause nervousness, irritability, sleeplessness, and, occasionally, rapid heartbeat. Always begin use with 1/2 scoop or less and assess your tolerance. Once tolerance is assessed, take a maximum dose of 1 scoop. To avoid sleeplessness, do not consume within 6 hours of bedtime. This product contains chemicals known to the State of California to cause cancer and birth defects or reproductive harm. KEEP OUT OF REACH OF CHILDREN.

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.

Not impressed
My order of pre jym came hard as a rock and my email to gnc for a trade for a new tub went unanswered. I may just order from from now on. Also, I wasnâ??t able to log into the site after registering. Frustrating experience.

great energy and focus
The energy nd focus gained from this pwo is awesome. Also great how it contains creatine and aminos all in one product. Helps with the workout and recovery. If you take this and Post JYM you have everything you need...minus protein

Lives up to its claims!
Me and my sons use this product religiously. You can definitely feel a difference when you workout without Pre Jym
