Artica Masteron P 100 is a synthetic derivative of dihydrotestosterone, producing an anabolic effect and promoting protein synthesis as well as creating positive nitrogen balance in humans. Since it is a derivative of dihydrotestosterone, Masteron does not aromatize to estrogens. Master P 100 has significant anabolic and androgenic properties promoting an increase in 2 strength and growth of muscle tissue while acting as an estrogen antagonist. The combination of a short-acting propionate ester with a longacting enanthate ester pro- duces rapid increases in serum Drostanolone levels with a sustained duration of 2-3 days.



Drostanolone aches to androgen receptors; increasing nitrogen retention and protein synthesis. Drostanolone acts on DHT modulated pathways as well. Drostanolone is a potent estrogen antagonist and does not aromatize estrogen, limiting expression of side effects often linked to estrogen such as water retention, gynecomastia, and some types of high blood pressure. Drostanolone undergoes hepatic metabolism with a half- life of 2-3 days after separation of the ester.
