# Masteron Enanthate

*Also known as: Drostanolone Enth, Mast E*

Longer-acting drostanolone ester. Simple model — peak calibrated.

## Overview

Masteron enanthate (drostanolone enanthate, Mast E) is an injectable DHT-derived anabolic steroid and the longer-acting sibling of drostanolone propionate. The enanthate ester extends the depot release so it needs less frequent injection than the propionate version. As a DHT derivative, drostanolone cannot aromatize to estrogen, and it competes with estrogen at receptor sites, which is the basis for its reputation as a hardening or anti-estrogenic cutting agent. The dataset lists a half-life of 8 days (192 hours), Cmax near 96 ng/dL, and bioavailability around 73%. Research and athletic protocols inject it twice weekly, reflecting that long ester. It is not hepatotoxic and does not aromatize, which lowers the estrogen-management burden.
