BP Proviron 25

Proviron, also known as Mesterolone, is an orally active compound that has been prescribed to men struggling with hypogonadism – a condition in which they are unable to produce as much testosterone as they should be.

Mesterolone, known also by the brand name Proviron, is a compound that’s very similar to Masteron – as you might be able to tell from their similar names. Mesterolone is an orally active compound that’s similar to dihydrotestosterone. Specifically, it’s a 1-methylated dihydrotestosterone molecule.

One of the main changes that methylating DHT in this particular place does is allows Proviron to be consumed orally. This is much different than a lot of other steroids which need to be injected for any effect to be felt.
