Mast E

Masteron Enanthate, commonly known as Mast E, is a long-acting injectable DHT-derived anabolic steroid (Drostanolone Enanthate) prized for its hardening, aesthetic-enhancing, and anti-estrogenic properties. Originally developed to treat breast cancer, Masteron has become a favorite among bodybuilders, especially during cutting cycles and contest prep, due to its ability to enhance muscle definition and vascularity without water retention.

Its enanthate ester provides a slow, steady release, requiring fewer injections than the propionate version (Mast P), making it more convenient for longer cycles.
