Information about Mesterolone
Proviron contains mesterolone at a dose of 25 mg per tablet. It is not an anabolic steroid but a very powerful anti-estrogen. It prevents gynecomastia while reducing water and fat retention, it allows the resumption of testosterone production in the testicles, prevents the aromatization of anabolic steroids, and also reduces water retention.
Proviron acts as a anti-aromaticIt prevents the aromatization (the conversion) of anabolic steroids into estrogen. This prevents gynecomastia and it can be combined with Nolvadex to increase its effectiveness. It's important to note that Proviron and Nolvadex are both anti-estrogens with different yet complementary mechanisms of action, which is why combining these two products is so effective: while Proviron prevents the aromatization of anabolic steroids, Nolvadex blocks estrogen receptor cells, preventing estrogen from acting. It is therefore a formidable combination.
Proviron is not only an excellent anti-estrogen: by maintaining low estrogen levels, Proviron also reduces water retention. It thus gives the user the ripped look sought after by so many bodybuilders, especially during competition preparations.
It should be noted that Proviron tends to limit muscle gains from a steroid cycle because it binds to androgen receptor cells instead of other steroids present in the body, which then remain blocked outside and therefore ineffective. This is why many bodybuilders take a minimal dose of Proviron, just to avoid gynecomastia.
As for the side effects of mesterolone, they are rare below 100 mg per day. Indeed, the tablets of Proviron are not alpha-alkylated 17 and do not present any harmfulness for the liver. On the other hand, if we start to exceed 75 to 100 mg per day, we frequently see phenomena such as priapism (is a painful situation in which the penis after erection does not regain its normal flaccidity) in the man or virilization in women.
One to two 25mg tablets per day are sufficient to prevent gynecomastia.
