My Guarantee

I've taken the decades I've spent in school, the lab, the gym, and the kitchen and distilled them into the very product you hold in your hands. I formulated every JYM Supplement Science product to include the same ingredients at the exact amount I use to reap maximum performance and physique benefits. It's my hope that you, too, will experience similar results.

Suggested Use

As a dietary supplement, mix 1 scoop of PreJYM™ in 16-24 oz. of water and drink 30-45 minutes before workouts. Initially use 1/2 serving or less to assess tolerance. Once tolerance is assessed, take no more than 1 serving. To avoid sleeplessness, do not consume within 6 hours of bedtime.

For better results, consider using Post JYM Recovery Matrix™ after workouts.
