Clean energy without the jitters. I've tried at least a dozen pre-workouts and this is the first one that doesn't make me feel wired. The L-Theanine pairing is smart.

Finally a pre-workout with transparent dosing. No proprietary blends, every ingredient listed. The pumps from the citrulline are real.

Great formula. Mixes well and the unflavored option makes it easy to add to whatever I'm drinking. Would love a slight mint flavor option in the future.

I'm sensitive to most pre-workouts but this one sits well. The beta-alanine tingling is there but mild. Solid focus for early morning sessions.
