Sustenol 250 (Drostanozol) is typically used as a muscle hardener and strength increaser. It has been notably able to sharpen the appearance of individuals that already carry a low bodyfat percentage. Drostanozol has a chemical structure that may assist in recovery from bouts of extreme body stress including heavy weight training. Upon administration of Drostanozol, subdermal water levels may drop dramatically. Users often report of the skin taking on an almost paper thin appearance.
