Description
Mastex
Masteron is a steroid that’s derived from dihydrotestosterone (DHT) with a slight chemical alteration that gives Masteron a higher miscellaneous rating than DHT itself. By suppressing the aromatase enzyme, Masteron Propionate has the ability to block the alteration of free testosterone to estrogen by the aromatization pathway and thus prevents any side effects to occur which would have occurred if it would have converted into estrogen.
