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.
