Suspecting, and knowing are completely different things.

I am mid 50's and do not take supplements. I have to admit some consideration to talking to my HCP about it as I have absolutely zero energy, zero drive, zero stamina for anything. I am also concerned about the possibility of the side effects and concerns about having to be on it from then forward especially where policy changes and whatnot could make such 'drugs' less available or harder to get.

A buddy of mine who is within months in age to me started supplementing about a year ago and his life is much like mine was in my early 40's as far as his own musculature and energy levels. He was already balding, so that aspect didn't matter.
