Serious fuel for athletes who train on the edge.
Berserker Stim™ was formulated for lifters and competitors who demand maximum drive, cell-swelling pumps, and locked-in focus—every session, no excuses. One full 2-scoop serving (40.4 g) delivers the clinical doses you need to push harder, last longer, and recover faster between sets.
