Not that I question your research abilities, banana, I know you are a wealth of knowledge but I gotta push back on this one.
I've run all kinds of androgens this past year and have yet to lose a single hair on my head. I actually have more hair than when I started. Sure it's on my back and shoulders but that's besides the point.
Funny thing is I have a younger brother (same parents) and he's been balding for years with no gear usage. It really does seem to be highly individual.
Edit: and no I have never used anything that prevent hair loss
