Mesterolone was developed medically to treat hypogonadism in men
which causes low testosterone. Although it is sometimes loosely
considered to be an AAS (androgen and anabolic steroid), it contains
little anabolic capacity and so has only weak anabolic benefits.
For this reason Mesterolone Proviron is not one of the those compounds that you will use for mass building or bulking, but it can still have some specific purposes for bodybuilders and some benefits that will interest those who make use of other anabolic steroids.
This is an oral product based on dihydrotestosterone (DHT) with some modifications. The weak anabolic effects of Proviron come about because of the way it is broken down and made inactive once it is in the muscle tissue – something that also occurs with DHT itself.
The lack of anabolic effects is why Mesterolone Proviron is sometimes named simply as an androgen rather than an anabolic steroid and is the reason why this isn’t a compound to use for mass gaining; simply increasing the dose and hoping it will deliver muscle gains is not the way to use Proviron but it can be an easy mistake for a beginner to make with any steroid.
That’s why we need to fully understand the purpose of Mesterolone for bodybuilders and steroid users, so you can best decide where it will fit into your cycles and overall goals.
