Mesterolone is an orally applicable androgen and dihydrotestosterone (DHT) derivative.In the late 70s and early 80s, it was used with some success in controlled studies of men suffering from various forms of depression.
Just as with DHT, the activity of this steroid is that of a strong androgen which does not aromatize into estrogen. Mesterolone is generally used to treat various types of sexual dysfunction, which often result from a low endogenous testosterone level. It can usually reverse problems of sexual disinterest and impotency, and is sometimes used to increase the sperm count.
Although this steroid is strongly androgenic, the anabolic effect of it is considered too weak for muscle building purposes.Proviron/Mesterolone may actually work to potentate the activity of other steroids by displacing a higher percentage into a free, unbound state. Among athletes Proviron® is primarily used as an antiestrogen.Mesterolone is believed to act as an antiaromatase in the body, preventing or slowing the conversion of steroids into estrogen. Proviro can supplement a wellneeded androgen, and bring about an increase in the hardness and density of the muscles. Women in particular find a single 25mg tablet will efficiently shift the androgen/estrogen ratio, and can have a great impact on the physique.
Mesterolone supplements ones natural testosterone, sperm production (spermatogenesis) is unimpaired by mesterolone when compared with other drugs used in this area
During the late 1970s, doctors who performed studies on mesterolone concluded that the drug could be used to treat depression in some men. Patients with symptoms of anxiety and low sex drive reported improvement with low doses of the steroid. During the study, higher doses proved helpful to patients with dysthymia and bipolar depression as well. Since this time, newer studies have shown that patients taking a placebo improved at the same rate as patients taking mesterolone, leading medical professionals to believe that better drug options exit.
Mesterolone is often used as an antiestrogenic treatment and may be used by those who have had a poor reaction to testosterone treatments. The drug has shown to be beneficial in treating sexual dysfunction, impotency and low libido. Mesterolone binds to estrogen receptors, reducing their activity, which not only reduces estrogen production, but also encourages natural testosterone production in the body.

Mesterolone had seen widespread use in bodybuilding primarily for antiestrogenic activity in anabolic steroid stacks but such use has declined after introduction of aromatase inhibitors and SERMs. Most significant benefits of current Mesterolone use are considered to be maintaining libido off-cycle and also relatively and temporarily improving vascularity.
