Hi, I'm on a hairloss drug called Propecia at the moment. I suffering from minor erectile dysfunction as a result of it, so I was thinking of going off it for a while. I've been on this drug for a 2 months now (since the 10th of november). However I just want to know will this drug (since it's a DHT inhibitor) prevent any further penile growth? I was going through a growth spurt around october november time where my cock grew further 1/4 of an inch (8 1/4 to 8 1/2), which I was amazed about it. However I've not noticed anything since. I'm only 20, don't turn 21 till august and I believe I'm still going through some form of puberty (I've only just began to grow hairs on my chest, facial hair is beginning to get increasingly thick and I'm still getting spots lol). I'd be devistated if I knew that my penis would go close to 9" and I didn't forfill it because of this drug. I still probably have 6 months to a year of growth left I reckon so all is not lost (if that were the case), but I beginning to wonder whether or not I should delay using this drug for another year or so just make sure everything's fully grown.
