Proviron is a modified derivative of dihydrotestosterone (DHT) via the addition of a methyl group on its first carbon (1-methyl dihydrotestosterone). As previously mentioned, it is an extremely weak anabolic, which is why Proviron is almost always referred to as an androgen (or androgenic steroid). Studies have demonstrated the reason for its weak anabolic effects: it shares with its parent compound (DHT) a similar property – it is rapidly metabolized and broken down into inactive metabolites once it enters into muscle tissue.
This has always been the problem with dihydrotestosterone itself – once it enters muscle tissue, the enzyme 3-hydroxysteroid dehydrogenase (where it is in very high concentration in muscle tissue) binds to it, and renders it inactive by converting it into a compound that has no anabolic effects. This is the real reason for Proviron’s weak anabolic effects. There have been false rumors about Proviron’s weak anabolic nature in circulation among bodybuilding communities that Proviron “blocks the androgen receptor in muscle tissue”, which is wrong, and this rumor should therefore be put to rest.
Proviron Cycles and Uses
Being that Proviron is not an anabolic steroid and possesses extremely weak anabolic effects, it is not utilized in the form of cycles. It is instead normally utilized as anancillary compound, as an adjunct to anabolic steroid cycles in order to minimize or mitigate the effects of Estrogen on the body. It is also used for its aesthetic effects in enhancing the ‘hard’ look of the physique both through its effects as an anti-estrogen, as well as its effects as a strong androgen.
When used as an ancillary, it can be taken by male athletes and bodybuilders allthroughout their cycle length at 50 – 100mg per day, as there is no limit to how long it can be utilized for. Some individuals prefer to also run Proviron as a PCT (Post Cycle Therapy) drug in order to reduce Estrogen levels and boost fertility. Although this can be done, there are much better compounds with similar (and stronger) effects for PCT. When the risk of even weak endogenous Testosterone suppression is thrown into the mix with Proviron, it is advised to avoid the use of Proviron for PCT purposes unless there are no other options available.
