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.
Man, masteron is my fav drug so far. I literally feel like i'm on steroids when i'm injecting that **** into my body. It's like a having rock hard shelf under your skin. My current cycle is 250mg test e and 400mg of masteron e . i also take letro with these. Masteron gives you the agression to train hard, increases your stamina during the workouts, i also feel like it enhance with my cardio training in a very good way. It is prolly the most underrated compound, but man trut me, if you are a experienced bodybuilder and have enough lbm on you, masteron will take you to the next level. Ask pros.
