JYM Nutritionals – Pre JYM

Pre JYM: JYM Supplement is best known for its founder and lead researcher, Dr. Jim Stoppani, PhD. JYM started as a strategic partnership with Bodybuilding.com as an exclusive brand for the site. The unique blend of being one of the first exclusive online brands with the backing of a Doctorate PhD in Exercise Physiology made JYM supplements like PreJYM an instant success.  They can be credited with clincical doses of L-Citrulline and pushing the caffeine content of the post-1,3-DMAA preworkout market to a new threshold in the early to mid 2010’s.

Currently, JYM has raised itself to the top of the hill with representation at retail outlets like GNC, Vitamin Shoppe, and e-retailers like Amazon. They have a full line up of pre, peri, and post workouts products designed to address any need of the fitness elite or just a gym newbie looking to get the most out their initial gains.

Pre JYM is the flagship of the JYM line up. It represents the turning point of a marked category of supplements that has seen everything from lawsuits to bans, and out of the chaos came PreJYM to break the cycle of shadiness and concentrated prop blend preworkouts. Solid doses, science back, and PhD certified you can guarantee Jim Stoppani is putting his rep on the line with every product, and he has zero hesitation in proving he is here to get you the gains you deserve.
