I like that it had 200mg of caffeine. It’s nice to have if I have a later workout and won’t keep me up. Good pumps 💪🏼

👍

Part of my morning routine.

One of my favorite pre workouts the favor is great and the pre workout gets out through those hard workouts sessions.

Nitraflex Sport has been a game changer for my workouts. The energy boost is clean and lasts through my entire training session without the crash I’ve had with other pre-workouts. I also noticed improved focus and endurance, especially on heavier lifts. The taste is great and it mixes easily, which makes it super convenient. Definitely something I’d recommend to anyone serious about getting the most out of their gym sessions
