Masteron vs. Proviron

Q: What is the difference between Proviron and Masteron? I heard they are both DHT derivates and one was really just an oral form of the other. Could I use Proviron instead of Masteron for contest prep? I lost my source for BD Mastabol.

A: Proviron (oral 1-methyl-dihydrotestosterone) and Masteron (an injectable form of 2-methyl-dihydrotestosterne) are indeed structurally very similar. Both are DHT hormones with a minor modification (methylation) on each. This similarity, however, doesn’t carry over extremely closely when it comes to function. Both steroids are DHT derivatives, yes, and because of this there is no estrogen conversion possible with either drug. They lack a structural trait necessary for their conversion to estrogen. This characteristic may also allow both steroids to offer some level of anti-estrogenic activity, as the non-aromatizable steroid may compete with other aromatizable steroids (like your own endogenous testosterone) for binding to the aromatase enzyme. This should lower estrogen levels and heighten the ratio of relative androgenic to estrogenic activity in the body. As such, both steroids could be used to some extent for cutting or contest preparations. The main value in this regard is that both may help, instead of hinder, the visible retention of fat and subcutaneous water. With less water retained, muscle definition can increase provided body fat is low enough. But this is about where the functional similarities between the two agents end.
