Proviron is pretty useless as an anabolic. However it has some other properties that make it worth adding to a cycle. One of biggest benefits is that it has a stronger affinity for SHBG than test, so it 'sacrifices' itself leaving more free test available in the bloodstream. Secondly it acts as an anti-aromatase similar to arimidex, so it will lower estrogen levels and associated bloat. It's very andorogenic, so it will help your libido but may also accelerate any hair loss.
