Trust me my libido is not fucked up by Proscar. Not at all. I even made a blood test to be sure everything was normal, and everything's fine. I have a prescription for it and while I'm gonna be on cycle I will continue to use it.
Concerning libido side you're talking, it could be a possibility if you take the whole pill which is 5mg during a certain amount of Time. But as far as I concern, I take 1,25 mg everyday for 5 years and no sides at all. Try it and you'll se by yourself, and if you experiencing a side, well, just stop it.
