Absolutely. The reason BTG is the best var is because they have the technology to make it very bioavailable. The pharmaceutical industry tries to find the best delivery systems to insure that the minimun amount of a drug is needed to minimize side effects. It's not really a matter of the quality of the var, ACS grade, USP23, USP24 and so on but more of an issue of absorption by the body.
The best way to do this is through injection not tabs, patches, snorting or anything else.
That's why Injected Fina(although not 17AA) is so much better when injected than applied with DMSO.
