V-Med Oral Proviron 25

Proviron is a purely androgenic steroid with no anabolic qualities. The drug was used both as an anti-estrogen that “prevents” estrogen from being produced through the aromatization of sex steroids, and for its hardening effect upon musculature. Unlike Nolvadex (which only keeps estrogen from bonding with its receptors by blocking them), Proviron actually prevents the formation of estrogen. Due to lower estrogen levels, athletes retained less water and prevented (for the most part) the formation of gyno and female pattern fat deposits.
