Proviron 25mg, 100 pills per bottle
Proviron is an oral DHT steroid compound similar to Masteron. Although it is not an ideal compound for building muscle, Proviron is helpful in stacks because of its unique ability to keep the body from turning testosterone into estrogen, thus giving the testosterone a better anabolic effect. This aids the bodybuilder in many ways. First, it helps reduce estrogenic side effects of other steroids water-retention, lowered sex drive, gynocomastia, etc.
Proviron can help boost the potency of testosterone in the body by freeing testosterone from its binding to sex hormone-binding globulin, therefore best stacked with testosterone, which makes taking anti-estrogen compounds unnecessary.
