Nitraflex Advanced Pre-Workout Powder, Increases Blood Flow, Boosts Strength and Energy, Improves Exercise Performance (Grape, 30 Servings)

I already wrote a more extensive review of the Black Cherry flavor that i consistently buy from another seller. In the interest of not being repetative and risking Amazon flagging me for being a robot or something, I will make this brief. I order this flavor when the black cherry is out of stock, but it is almost as good. Ive been using Nitraflex exclusively for years. It's the only pre-workout I found that not only has the caffeine boost that I need, but they add a few other things into the mix that assist in improving my workouts and the effects afterwards. As a guy who works out 7days a week and spent over a decade int he health and fitness industry, I highly recommend Nitraflex.

Best product I’ve used worth the price taste and smells good . Helps me focus and works in making you feel great!

This prework out does not disappoint. No jitters after taking it

Very good energy and good taste

I feel a good surge of power when im starting to warm and just gives me the felling of DRIVE im assuming its the Testosterone enhancing it has in it but ive been taking it for 2 weeks now and its been good! Its a big upgrade from Nitro Surge and C4 EXP would recommend 👌

Get up and go go go. Decent taste, nice energy no jitters if taken as directed. Recommend half dosing at first to see personal tolerance. Only drawback is if taken later in the day you will definitely be awake after hours.

Was looking for a different pre-work out alternative, this is one of the best ones I've tried. I would recommend this if your not looking for an extreme jittery feel, but focus and performance. Will buy again!

Been using nitraflex forever. Only pre workout I use, I just get them online here cause at the supplement stores they only have one or two flavors and online I can get other flavors I haven’t tried. Taste good, not too sweet. Love it
