As well as allowing people to lose weight though, methamphetamine also made them feel good and so when it was made illegal, as it was easy to produce, many people started to make it illegally to sell on the streets as a recreational drug. If the takers of this now illegal drug were to learn more about meth and the body they would see that the nice effect it seems to have on the brain, also causes them to become paranoid, irritable and even sometimes aggressive and that they may also start to suffer from insomnia. Although that alone, if people knew, may be enough to stop some people from taking the drug, the fact that it can have even more serious effects on other parts of the body may persuade others not to take it.
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.
