Funciton of Mesterolone

Mesterolone is a dihydrotestosterone (DHT) derived anabolic androgenic steroid. Specifically it is a structurally altered DHT hormone possessing the addition of a methyl group at the carbon one position. This allows the hormone to survive oral ingestion by protecting it from hepatic breakdown. This is one of the only oral anabolic steroids that is not C17-alpha alkylated (C17-aa) but instead carries the added methyl group. Oral Primobolan is the other most well-known oral steroid that carries this same methyl group. While the added methyl group does in fact protect it from breakdown, the total bioavailability of Proviron will be far less than most all C17-aa oral steroids.


Effects of Proviron

During a bulking phase Proviron is not going to be a foundational steroid, and for most men it will not have a place in an off-season cycle. There are exceptions and we’ll go over those here. Adding in Proviron could possibly help the individual breakthrough a sticking point during his cycle. At some point and time in all cycles the progress begins to wane, and in some cases come to a complete halt. By the way Proviron enhances the total free state of the other steroids being used in a stack, it could possibly help the individual breakthrough this sticking point. During the off-season, this is where most will use the largest amount of testosterone. Many will use large amounts during cutting cycles too, especially competitive bodybuilders but lower testosterone plans are more common during the cutting phase. However, there are those for numerous reasons who choose to run off-season cycles with limited testosterone doses. In such plans, including Proviron could give them a slight needed androgen boost. While it may not always be necessary it could prove to be beneficial.
