Lastly Proviron is the only androgen that does not effect the natural production of testosterone when the dose is kept moderate and below 150mg per day. Then the HPTA axis does not get suppressed. The fact that it increases androgenic activity without suppressing natural testosterone means that it increases an athlete’s sperm count and it can be used with your PCT (post cycle treatment) if your aim is to procreate (have a child). When a athlete wants to take pure anabolics like Deca or Anavar and he is worried that his natural testosterone level will drop to much it is also very beneficial to include Proviron to ensure you have enough testosterone for normal bodily function. The Proviron on a pure anabolic stack will prevent the testosterone from falling to low.
