Yes.....Mesterolone (Proviron) is an oral form of Drostanolone (Masteron)
No.......Proviron and Masteron DOES NOT kick in your own testosteron (quite suppressive of natural testosterone).
Drostanolone (Masteron) is structurally a 2-methylated form of the hormone dihydrotestosterone (DHT). Proviron is a 1-methylated form of the hormone dihydrotestosterone (DHT).
If you looking to reduce body-fat and water retention, Drostanolone, is literally a dream. Being 5-alpha reduced, cannot form estrogen upon interaction with the aromatase enzyme yet still shows a very high affinity for it. Because it takes up so much of the aromatase enzyme, yet is refrained from actually using it by its structural make-up, it reduces the amount of estrogen formed from other steroids as well because there are less aromatase enzymes to be used by those compounds to form estrogen with.
The reduction of estrogenic capacity of course makes drostanolone ill-suited for use as a mass-builder. In fact, the gains on it are quite limited. Someone seeking to gain muscle mass rarely, if ever, resorted to a DHT compound. But coupled to its extreme androgenic qualities it leads to the perfect compound to retain strength and mass while shedding body-fat.
Drostanolone enhances the potency of testosterone. Testosterone in the body at normal physiological levels is mostly inactive. As much as 97 or 98 percent of testosterone in that amount is bound to sex hormone binding globulin (SHBG) and albumin, two proteins. In such a form testosterone is mostly inactive. But as with the aromatase enzyme, DHT has a higher affinity for these proteins than testosterone does, so when administered simultaneously the mesterolone will attach to the SHBG and albumin, leaving larger amounts of free testosterone to mediate anabolic activities such as protein synthesis.
Perhaps the most favorable effect of drostanolone is that it can increase muscle hardness and density.
