I hate to lend some validity to this thread but there is some truth in that if your test/DHT levels are sub-normal for long enough, some atrophy will likely occur, which can generally be reversed upon resumption of normal hormonal levels. On the other hand, keeping test/DHT levels optimal or above normal, along with an active sex life will assure you are at maximum potential. And during puberty test/DHT levels are critical to proper development of the forearm.
