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. Many people prefer to use DHT over testosterone because DHT is more androgenic . It’s actually believed to be more than 3 times as potent as testosterone, and it also can’t be turned into estrogen through the process of aromatization.
