Prolactin inhibitor in a testosterone booster - is something completely new! Several years ago experts from Olimp Laboratories stopped designing dietary supplements aimed at increasing the internal production of testosterone affecting the body by using only one biochemical mechanism. As science develops and the demands of professional athletes concerning the quality of products continue to increase (it is now required that as well as increasing the level of testosterone, that products neutralise the adverse effects of elevated concentrations of oestrogen and prolactin), the whole potential currently offered by completely legal and safe active substances has been implemented in one advanced product stimulating the production of testosterone - the DAA Xtreme PROLACT-BLOCK. At the same time, it is also a viable alternative to extremely harmful anabolic-androgenic steroid-like products. Nowadays, virtually all sports based on strength or speed and strength workouts, directly connect workout results with the body’s level of testosterone.
