The notion of the Uzbeki source (a university in Uzbekistan) being the one true supplier of proper ecdysterone was a myth. The problem is that ecdysterone is an expensive chemical to source for anyone and everyone, and weighed against the tried-and-true compounds it's not worth it (it's more expensive than hGH). There is no economic reality under which any supplement company can make money selling it, so it's all severely underdosed as I mentioned in the informal review. It does work: you will notice an appetite boost if you take enough of a decent ecdy supplement. If you don't notice an appetite boost you're not taking very much.
And yea my guy's source for turk was from a university in uzbekistan, I remember when he sent me the link with all their contact info. This is where I believe tonvara and gorilla mode source their turk too.
