MAST-200 (DE 200) Drostanolone Enanathate Oil Steroids Injectable 200mg/ml

Description

Masteron Drostanolone DHT Derivative Injectable Research

Pharmacodynamics

The pharmacology of Drostanolone Enanthate is rooted in its high affinity for the nuclear androgen receptor (AR) and its lack of interaction with the aromatase enzyme. Drostanolone Enanthate functions as a high-affinity ligand for the AR, promoting the translocation of the receptor complex into the nucleus to initiate myogenic gene transcription. The 2-methyl group provides metabolic stability against enzymatic breakdown in skeletal muscle, ensuring the compound remains active longer than native DHT. Furthermore, the Enanthate ester regulates the liberation rate of the steroid from the intramuscular depot, resulting in a terminal half-life of approximately 7 to 10 days. Quantitative binding assays indicate that Drostanolone also exhibits mild anti-estrogenic properties by potentially competing for the aromatase enzyme or modulating estrogen receptor (ER) sensitivity. This unique dual action makes it a focal point for research involving body composition and hormonal homeostasis.

About This Compound

Drostanolone Enanthate, known in research circles as MAST, is a long-estered synthetic derivative of dihydrotestosterone (DHT) characterized by a 2-methyl group modification. This structural alteration enhances the molecule’s anabolic potency while providing significant resistance to metabolic deactivation by 3α-hydroxysteroid dehydrogenase. Researchers utilize this compound to investigate late-stage tissue hardening and the modulation of estrogenic signaling in advanced biological models. Unlike its propionate counterpart, the Enanthate variant is engineered for a sustained release profile, reducing the frequency of administration in chronic studies.
