Usnic acid source

Does any body know of a secure/working usnic acid source. www.vialsandcrimpers.com doesn't carry it anymore (even though it's on the page; I got an email from them). Don't flame me because this stuff is legal, otherwise I wouldn't be asking.

I don't think I can mention sources but you can get usnic acid from the guy in China who is often called "Bruce Lee". He has been mentioned on this board many times.

Usnic acid took away all of my energy so if you use it you might not have enough energy to train.
