Hey im a 20 year old already losing my hair. My dad had the same issue still has hair but has a recedeed hairline and loss of hair at the vertex. I was prescribed proscar at 1.25mg a day and started 4 days ago. Now Ive read that in some people it can affect muscle gains and ive been working out since i was about 16. Anyways ever since i have started it i have felt a weakness in my muscles,mostly in my biceps. I can still lift as heavy as i normally do but even when im not at the gym i feel a weakness especially in the biceps. I work out 4-5 times a week and have not had this issue before. I did do some research before to see if it would affect my gains... Is there anybody else thats had this happen to them? Is it maybe my body that is not used to having so many hormonal changes in the body and needs time to get used to? Will it actually effect my gains? Sorry for the bombardment of questions im just worried and would like you guys opinion. Thanks
