Pre Workout without the Filler

Review by Matt on Jul 16, 2021
I used to be on the pre workout bandwagon many years ago. Tried a lot of brands and after years of varied results I decided to give it a rest. It was all so unregulated and the “proprietary blends” were always changing every four months. Beta alanine is the pre workout without the “proprietary blend” bullcrap. This beta alanine is what you want. Works as advertised; delays muscle fatigue. It’s the ingredient that makes you feel tingly, but without the jitter of the caffeine-laced pre workouts. I’ve noticed it ups my focus, but that could just be placebo, who knows. Either way, it’s a noticeable difference in mid-workout energy and endurance.

worth it

Im cynical as hell. This is my second delivery of beta alanine, though. I POWER through my workouts since starting it. Noticeable difference. Im so pleasantly surprised. So are my glutes.

I tried Optimum Nutrition's Beta-Alanine a few years back and in my comparisons to other companies beta-alanine supps, I've found my way back to ON's Beta-Alanine because NO OTHER companies even come close to the perfected effectiveness that Optimun Nutrition has made! Just taking this alone, I've noticed a difference in my body appearance, plus the added benefits of better endurance!
