Pre JYM Pre-Workout

Pre JYM was formulated by Dr. Jim Stoppani, an exercise physiologist, and is sold under the JYM Supplement Science brand. It is known for fully transparent labeling with no proprietary blends, meaning every ingredient and its exact dose is disclosed on the supplement facts panel.

Creatine nitrate, used in Pre JYM, bonds creatine to a nitrate molecule, which may improve water solubility and potentially support nitric oxide production for better pumps during training. Creatine monohydrate is the most extensively studied form, but creatine nitrate is marketed as combining creatine and nitrate benefits in a single compound.

Pre JYM uses fully disclosed dosing, meaning every ingredient — including citrulline malate, beta-alanine, and creatine nitrate — is listed with its exact amount on the label. This was a deliberate decision by Dr. Jim Stoppani to differentiate Pre JYM from competitors that hide individual ingredient amounts behind proprietary blend names.

Pre JYM is marketed with performance ingredients like creatine nitrate, beta-alanine, and citrulline malate, but you should carefully review the full label for any stimulant content before using it if you are stimulant-sensitive. Starting with a half serving is a common approach to assess your tolerance to any pre-workout supplement.
