As a bulking agent, the effects of Masteron will prove to be rather weak. It is possible the hormone could provide gains in mass similar to Primobolan (which wouldn’t be that strong either) if the total dose was sufficiently high. However, the relative gain in size will be moderate with many anabolic steroids being far more suited for this period of steroidal supplementation. Masteron does not aromatize and is not estrogenic; in fact, it shows anti-estrogenic traits in the body and binds to aromatase instead of other substrates. This is why it has been effective in the treatment of breast cancer.
To summarize, drostanolone acts very similar to stanozolol, however it does not have side effects typical for Winstrol, namely it does not increase tendon brittleness, does not dry out the joint fluid and does not have such an adverse effect on blood cholesterol as stanozolol does. If one were to choose between drostanolone and stanozolol for a cutting cycle, drostanolone would be a more reasonable and safer option!
