How exactly does the body shut off natural production of testosterone when you take AAS? Is it an on/off switch or rather dose-dependent? Is it possible to keep natty test levels up by using D-Aspartic Acid (DAA), which raises test and LH production?

I did a search on DAA in this forum. Lots of posts are when DAA was too expensive for the average bodybuilder. Now it's cheap and worth the money. But can it keep natty test up while you're using an AAS?
