Might be a stupid question but, I see different grades of powders..USP 24,26,27, etc..Is one better than the other? Or does it have to do with purity? I know nothing is 100% pure, just curious..
 
UPS is a universal standard for classifying powders. USP 24 conforms to the standard of the 24th edition if I am not mistaken.
Im to lazy to but if you really want to know Google it!
