By inhibiting the aromatase enzyme, Masteron blocks the conversion of free testosterone to estrogen at the receptor level. This makes it efficient in increasing the amount of active free testosterone in circulation, additionally, it prevents estrogenic side-effects. It lowers the chance of water retention caused by some anabolic steroids and is especially beneficial for competing bodybuilders and athletes.
