Interesting. Maybe it's a psychological thing? Like, you start wanting to be on T so badly, or you're imagining being on T so much, that you're actually producing more T.
I've been exercising a lot more, in an attempt to raise my T level, and so far, I think it's working. You can actually see my stomach hairs now, they're dark brown, and my little trail is coming along nicely. Not to mention I just feel better in general. So, if you haven't been exercising on a regular basis, I definitely suggest it.
