Pre-JYM is a pre-workout supplement by Jim Stoppani.
It prides itself on a robust formula, aiming for the inclusion of a range of ingredients at the proven effective doses.

Huperzine-A and Alpha-GPC Choline may have a synergistic effect, boosting and preserving acetylcholine levels (the “learning” neurotransmitter).
Pre-JYM supplies a huge range of performance-boosting ingredients, mostly at effective doses. This covers many bases for increasing strength and endurance for effective workouts.
Creatine HCl is claimed to require a smaller dose than the usual monohydrate (3-5g), but research has not proved this.
The beta-alanine dose is low, but this may be to prevent the tingling sensation felt with larger doses.
The amount of beet extract in a serving doesn’t provide enough nitrates to have a significant effect.
The creatine and beet extract servings are too small to make much impact in this category.
Pre-JYM gives you a dose of BCAAs that you’d typically find in a pure BCAA product – basically giving you the benefit of two supplements in one, which is a huge bonus.

Pre-JYM definitely lives up to the hype in terms of its ingredient profile.
A variety of proven ingredients are included at effective doses, resulting in an off-the-chart score for performance, and a maxed out rating for pumps!
Scores for stimulants and mood/focus are also above average.
The extra 6g of BCAAs and added Piperine for increased absorption make Pre-JYM even more appealing.
