USP25, USP24 definition please

[buckwheat1]

Note I said "some will argue" concerning the 1% negating some effect of the drug.

I don't think it's a coincidence that BTG var which is USP25 works much better than an equally dosed chinese var which claims to be USP23. Could be other expedients in the BTG, but higher quality drugs do seem to be more effective.

Generic drugs supposedly contain the exact same active ingredient, but I have heard that sometimes the generics don't work as well. This may be due absorption issues. The name brand may have a better delivery system.

Still waiting on a textbook description on the USP grading system. Seems somebody got to know where this can be found.
