I am lookin to switch from duta to propecia. i have been taking both for about 5 days now. I was wonderin if this is ok and how much longer should I take the duta before the fina starts to work its magic. 2 weeks? Also, is duta a proscription yet or just a chem? I have a bad case of mpb and the duta doesnt seem to be doing the trick 100%, so im switching to propecia so I dont have to worry about the quality. I know duta could work better so a part of me is scared to switch to fina. any input would be greatly appreciated.
