Manufacturer's Description:

Masteron is the original given product name for Dromostanolone / Drostanolone. It is a modified derivative of DHT (Dihydrotestosterone). Masteron is a modified form of DHT.

For Masteron Propionate, where ‘Propionate’ is Propanoic acid, but when bound to Masteron it is properly referred to in chemistry as an ester bond. Propanoic acid is bonded to the 17-beta hydroxyl group on the Drostanolone chemical. The addition of this ester modifies the hormone’s half-life and release rate which provides a much longer extended release and half-life.

Because Masteron is a DHT-derivative, it retains some of the same characteristics as DHT, of which is its inability to interact with the aromatase enzyme. The aromatase enzyme is the enzyme responsible for the conversion of androgens into Estrogen. Estrogenic side effects are never an issue with Masteron which eliminates the following side-effects: water retention and bloating, elevated blood pressure (as a result of water retention), possible fat gain/retention, and gynecomastia.

Not only does it completely avoids the conversion into Estrogen, scientific evidence suggests that it acts as an aromatase inhibitor too. Side effects of Estrogen buildup (such as water retention, bloating, fat retention and gain, and the development of gynecomastia) are not an issue whatsoever when using Masteron.

Masteron definitely does hold a lower androgenic strength rating than Testosterone, androgenic side effects are still possible, especially among those who may be sensitive to it. Masteron’s androgenic side effects include: an increase in oily skin and acne, increased facial hair and bodily hair growth, as well as an increased risk of MPB (Male Pattern Baldness) in those whom may be predisposed to it. Virilization which is the development of male characteristics in women may also be a risk with females, though its use in female breast cancer patients.

Masteron may have more of a negative impact on cholesterol and the cardiovascular system than some other anabolic steroid compounds. This may indeed be due to Masteron’s anti-estrogenic properties. This may result in measurable reductions in HDL (‘good’) cholesterol, and increases in LDL (‘bad’) cholesterol[4].

Masteron exhibits no hepatotoxicity, but like any anabolic steroid, it does contribute to suppression/shutdown of the HPTA, thereby reducing endogenous production of Testosterone. Post Cycle Therapy is advised.

Masteron dosages are in the range of 200 – 400mg per week for beginners. Intermediate and even advanced users tend not to take dosages higher than the 400mg/week mark.
