Dht is responsible to penis growth; Proviron(steroid) is a DHT derivative and boy does it give you mega hard oms and constant sex drive. i usually take 50 mg for 2 weeks then 100 mg for 4 more weeks totallying 6 weeks. If your going to juice just avoid Deca and always add proviron and ask the juice gurus always as this is a Penis Enlargement forum not steroid forum
