Sensational. A complete supplement that meets all the needs of those who practice sports or bodybuilding. After taking 2 in the morning I feel more energy the 3rd volume after lunch. It has greatly improved my disposition and reasoning. A damaged shaft, I hope to get in touch with the evitamins and change. About the supplement, it is an almost impossible mission to find one of this quality in Brazil. Another differential is that it comes with Tribulus Terrestris, Peruvian Maca, ginseng and MCT, giving a sinister energy to the training, not counting bcaas that even in a small amount help a lot. Unlike many vitamins, I have not had any adverse reactions, perhaps because the best ingredients are used in your compost. Using beta-carotene instead of retinol acetate was also a major drawback, thus avoiding vitamin A hypervitaminosis. Overall, my next guaranteed purchase is when they're done. Delivery came quickly and I am very pleased with the whole purchase.
