My guess is that the doping scandals in major league sports likely has a lot to do with it. Face it, steroids work, and result in a substantial improvement in athletic performance, creating an incentive for 16 year old aspiring Division I college football players to start taking them when they absolutely should not be doing so. Unfortunately, that effort sweeps us 40 year old men up in the same dragnet.
Would be nice to see more and more physicians prescribing test for guys who are in the "acceptable" range, but want to be on the high side of normal. Would also like to see GH laws changed, as that really does have significant positive effects for aging men. I won't hold my breath, but perhaps these types of articles get a more healthy discussion of the topic happening.
