~Andrew.. lol There is nought you can do to make your voice deeper. When you hear it cracking when you speech, it's beginning to loose change. Only time will help you out.~
i hear that snorting dog dookie makes you smarter but ego really rather not...
Haven't hear that one sorry.
But this isn't going to be good but you will freshly have to hang about.
Sorry.
Probably a testosterone boost, which will help a short time, but quite insignificantly.
Other than that, nil else scientific I know of.
Hope this help :D
