Usnic Acid is an uncoupling protein that works the same way DNP does, although it is not nearly as potent....essentially it depletes ATP levels, resulting in rapid weight/fat loss....however, you feel like shit when on it....it does work wonders..i eat everything in site while using it and still never gained a lb....on it, just a little dieting does wonders......
HOWEVER, there have been some studies that suggest that it may cause chromosome damage, which can result in cancer.....Brock Strasser and Bill Roberts published a few well known articles on this issue....personally, i think they are both biased and attacking their competitors with a weak argument (they work for BIOTEST, and usnic acid was sold by SYNTRAX in their product Lipokinetix)........although, I personally play it safe and do not use Usnic Acid.......it does certainly work wonders, but It is a gamble....
