Fin is the key. It's perfectly benign unless you are overdosing on it. It has a long half life so its effects can be felt with as little as 0.5mg every 3 days. The sexual side effects meme is confirmation bias, studies show that the placebo group had the same rate of sexual complications ~5%, men just have sex issues these days and if they're on fin they blame the fin.

I did a shit ton of research before going on it as I'm a weightlifter and take pride in my test and strength, it's been 6 years now, no issues, thick head of hair. So take that advice, or don't, doesn't matter to me if you want to be a baldy.
