Could My Weightlifting 3 Times a Week Make Propecia Not Show Any Benefits?

Hi. I am 21 years old. About 9 months ago I noticed that my hair was thinning at the top. I consulted my GP and he said it was male pattern baldness. He prescribed propecia but after 7 months of taking it I experienced side effects and did not see any improvement. I lift weights for 30 mins 3 times a week and have a protein shake daily could this have any effect? Any advise would be greatly appreciated. many thanks

I doubt that there is any connection unless your protein shake has steroids in it.
