Review: Great value for the price, good taste, and it works! - I spent 30 years in the military training with both body and free weights. After retiring a few years ago, I slowly started working out less and drinking more (alcohol). After about 2 years I lost almost 20lbs. I finally decided to get in better shape and return to lifting heavy. In 3 months, I went from 172lbs to 186.4lbs using this product. I limit my dose to 3 scoops, 3 days a week. Definitely worth the money and it works!
Review: Muy bueno - Realmente me gusta mucho esta proteina desde su sabor hasta el resultado que produce en el volumen del cuerpo recomendado
