Surge with actual performance boosters with Styr Surge Stim Pre-Workout. Not your run-of-the mill pre-workout. Styr Surge is designed to fuel your workouts from the first set to your last workout set.

Energy & Focus

Caffeine anhydrous delivers clean, fast-acting energy, while L-tyrosine supports mental clarity when fatigue sets in. Choline bitartrate rounds it out by supporting the mind-muscle connection, so your head stays in the set.

Pumps & Blood Flow

L-citrulline drives nitric oxide production for the pumps you train for, with agmatine sulfate and L-arginine working alongside it to support vascularity and blood flow throughout the session.

Endurance & Output

Beta-alanine helps buffer fatigue so you can push deeper into high-rep sets, taurine supports hydration and muscle function, and L-carnitine supports energy metabolism during exercise.

Styr Surge has no proprietary blends, every milligram on the label.
