It must be a powerful drug, I take 0.4 mg per day. I cap at night before bed. That's the usual dose. Doc said sometimes that is doubled if you need more. I think If that doesn't work then they'll go for a drug that decreases dht.
Look up the literature on the net and see what it says. I dont know where you'd get some unless you see a doctor. I cant imagine its sold in the black market, but you never know.
To get mine I just saw my GP and he did a prostate exam, yeah that sucks! This drug is the first step in treating enlarged prostate.
If you dont have issues when you're off gear, I dont see any issues with going off. I know that I used to be that way when I was younger. Eventually that swelling you get while on steroids can become permanent. Genes play a role I think.
