Gives a good boost of energy and focus, plus a pretty decent pump. Only thing I can complain about is it seems inconsistent. Might be just me but some days it feels really strong, other days I don't feel much at all. Watermelon flavor is drinkable but not delicious by any means.

Try the tolerance dosage today for the first time and I got a pretty decent pump out of it. I slept like crap last night but still had a great workout. Started feeling it in my hands first, tingly feeling, then the face about 5 min later. At the gym, an itchy face which is pretty standard for me when I use pre-workouts so it really didn't bother me. The only reason I didn't give it a perfect 10 was because of the flavor. Don't get me wrong its good, it's just not great. Still, a solid product and will purchase again.

This is a **** never wrecking product, it gives you the pump you are dreaming off but downside no sleep plus very less amount of citrulline malate leaves you with soreness. PS:Tried on Indian genes here

This is the best pre I have used. Very easy to mix. No clumping and fast to mix. This flavor is great. Fast acting and lasts the workout. Very much worth it.

Product is ok. Black Cherry is identical to Nyquil cough medicine. The flavor gets a 0/10. Its disgusting unless you like taking meds before you work out.

Good pre-workout for any occasion. Pros: Good pump lasting ~1.5 hours Moderate paresthesia - Not too much like old Cellucor C4 but definitely noticeable Great flavor - Could drink this everyday and not hate myself Cons: Noticeable crash after workouts Definitely worth a try.

GAT Nitraflex is an excellent pre workout, it gave me a lot of energy when i didn't want to go to the gym and gave me a lot of energy when i was lifting heavy, on the other side it made me a little bit anxious and kind of felt nervous, it also made my arms a bit itchy for a very short period, but after starting to workout it went away. I find this product very efficient, it definitely gave me an amazing pump. Instagram: Iron_nephilim
