So far so good. It makes my body heat. I’m mot sure this is helping me to concentrate though. When I have one scoop, it also gave me a headache so I tried the other day with 2/3 scoop. It’s way better.
Excellent composition in the measure, cost benefit, quality in the training and efficient fulfills what it promises. Taste a delight, It is a pre-workout that the use of it will be part of my routine. Satisfied, stimulating in the measure and a pump!!!! and recommend. I'm a Brazilian lover of pre workouts and this one won me over "Iherb" congratulations for the product and for the logistics on delivery
