Mesterolone is rather a weak aromatase inhibitor, but it also interferes with estrogenic manifestations. Long-term experience shows that it is almost not able to suppress gynecomastia, formation of fatty deposits on the female type, and other consequences of the flavoring.
Proviron does not affect the production of testosterone, but at the same time increases the concentration of "dough" in the blood due to activation of globulin, sex hormone binding. Because of this steroid Proviron is a welcome tool in the cycle of AAS. No less often the drug is used as PCT, though not all consider it advisable due to lack of ability to restore the secretion of testosterone.

Mesterolone Cycle / Dosage
Mesterolone cycle is not used solo. Typically, this steroid is used in mixed cycle with other AAS as an anti-estrogen. The choice of such moments, usually is between Tamoxifen and Mesterolone. The first means, though, and blocks the activity of estrogen receptors, does not interfere to their production. Tamoxifen, given its ability to stimulate testosterone production, is able to influence the pituitary gland, as well as reduce the anabolic activity of parallel use of AAS. That is why it is taken only during the PCT. Mesterolone, on the contrary, is the prerogative in a cycle of steroids.
As for how to take Proviron, it usually means is used from the second week of the cycle at a dose of 50 milligrams, in conjunction with aromatase inhibitors. But after 2-3 weeks at the end of the cycle you should take Tamoxifen at a dose of 20 mg daily.
Mesterolone Side Effects
Possible side effects of Mesterolone are such as baldness and prostate hypertrophy caused by the chemical nature of the active substance and its similarity to Dihydrotestosterone. During the cycle of steroid it is recommended to carry out periodic examinations of the prostate. Possible, though extremely rare, benign and malignant tumors of the liver. Also, when exceeding the recommended dosage, and dosage regimen are not excluded such negative reactions such as abdominal bleeding, enlarged liver and pain in the upper abdomen. There are some erroneous information that Mesterolone reduces the effect of anabolic steroids, as having them act on the same receptors. Rebuttal to the obvious: first, high affinity binding of the drug to the proteins on the contrary increases the concentration of free speakers, and secondly, the anti-estrogen is very rapidly destroyed in the muscle due to inactive metabolites.
