This Clen is unreal!

I got a bottle of clen from my buddy and have used it this last week and have all ready dropped 6 pounds but I am curious I can not find it on this board. It is called "Liquid Research" It comes in a clear bottle with a light blue label on it. It says USP24 Liquid-Clen 125mcg/ml
What does USP24 mean? And also has anybody every used anything like this or know anything about it! Thanks so much!

A little late for these questions isn't it?

usp24 i believe is the purtiy/quality of the clen powder they use.
