Real, verified feedback from athletes who train with OMEN.
The energy is clean and the pumps are unreal. No jitters, no crash. Raspberry Crush tastes incredible and mixes without a single clump. I've cycled through every big-name pre on the market and nothing hits this smooth while still being fully dosed.Raspberry Crush

I feel dialed in the second it kicks in. The Alpha-GPC and tyrosine combo is no joke — it gets me through my heaviest leg days without my mind wandering. The energy lasts the full session and tapers off cleanly instead of dropping me off a cliff.Gummy Bear

Definitely potent, so start with half a scoop to assess tolerance. Once I dialed it in, the endurance boost from the beta-alanine is obvious. Great value for a fully transparent, clinically dosed formula. Knocking one star only because I wish there were more flavors.Raspberry Crush

Most high-stim pres wreck my gut. OMEN sits clean and I get all the energy with none of the discomfort. The pumps on push days are insane. This is my daily driver now.Gummy Bear
