In all seriousness, you can buy the APIs directly from China/India and compound them yourself. It's easy and dirt cheap, in most cases. This is typically how underground steroid labs and other illicit pharmacies work. It's in some cases how legitimate compounding pharmacies work.
So how do you know what you're getting is pure, or even real? Simple, before shipping it to the US, you send it over to an analytical lab in China and have them run GC/MS or LC/MS on the chemical raw material. Since it's supposedly a pure compound, that should be easy, and there's very rarely any ambiguity as to the results. This also ensures that you're not inadvertently importing anything on the DEA's scheduled list.
I assume communities exist on the Internet for this kind of "drug piracy"?
Nootropics were a pretty popular trend around the same time, and I knew a lot of guys who would import weird drugs and peptides from Russia and China. It's the same sort of procedure I outlined in my last post, in that you're ordering drugs or drug-active-ingredient-powder from abroad... And then hopefully testing it.
Roughly 10 years ago, when [redacted breakthrough drug] was released, I helped some friends set up a pirate pharmacy. Those were good times.
