I’m loving the Gymbros Frenzy Pre-Workout before hitting the gym. The clarity and stimulation it provides is second to none. It’s definitely a keeper in my supplement cupboard.

Great tasting pre workout without the crash!

Great energy, great pumps without crashing hard like other pre workouts. Good amount of caffeine that doesn’t give you the jitters but you definitely feel it.

I’m usually not a big fan of caffeinated pre workouts but this one is different! Tastes incredible and no weird aftertaste! The training sessions iv had while using this have been another level, keen to get in and smash it out and don’t feel like leaving the gym even once the session is over. Highly Recommend!
