Gynecomastia Started Years After Starting Propecia

I am 25 and I started taking propecia about 5 years ago. around two years ago however I took a prohormon called methasterone to increase muscle mass, totally unaware of the side affects. I developed gynocomastia soon after. My question is I no longer take prohormons but I still have gynocomastia with quite a bit of tenderness. Is any of caused from the propecia even though i didn’t have it the first three years of taking it?

That is interesting, and I’m surprised it would start years after the fact. You might want to consider stopping the Propecia for 2-3 weeks and see if the problem goes away. Definitely talk about this with your prescribing doctor before stopping the medication, though.
