Some questions about propecia from a newbie

[bigmanoncampus]

OK im 21 year old male and have a receeding hair line only in the temple areas at the moment.

I have just brought some nizoral shampoo, i havent brought regaine as ive heard it doesnt help with the temple area?

With regard to Propecia, is it worth taking it now? Does it help with the temple area?

Also whats the cheapest way of buying it in the UK?

Final question, has anyone here suffered permanant loss of libido as result of taking propecia?

Thanks in advance
