Proviron is a synthetic, orally effective androgen which does not have any androgenic characteristics. Proviron is used in school medicine to ease or cure disturbances eaused by a deficiency of male sex hormones. There are other better suited compounds for this (see HCG and Clomid). For this reason Proviron is unfortunately cunsidered by many to be a useless and unnecessary compound. You should be aware that Proviron is also an estrogen antagonist which prevents the aromatization. Unlike the antiestrogen Nolvadex which only blocks the estrogen receptors (see Nolvadex) Proviron already prevents the aromatizing. Therefore gynecomastia and increased water retention are successfully blocked. Today Clenbuterol is usually taken over the entire year since possible virilization symptoms cannot occur which is not yet the case with Proviron. Since Proviron is very effective users usually need only 50 mg/day which means that the users usually takes one 25 mg tablet in the morning and another 25 mg tablet in the evening. In some cases one 25 mg tablet per day is sufficient. When combining Proviron with Nolvadex (50 mg Proviron/day and 20 mg Nolvadex/day) this will lead to an almost complete suppression of estrogen.
