WTF is Potion 9?

There must be a hidden ingredient in there responsible for the euphoriant effects because none of what was listed on the front page looks like it could produce legit euphoria. Certainly not MDMA quality.

Sure there's no hidden cathinones or arylcyclohexlamines in there?

A few years back Methylone or 4MMC could've subbed for X but that's long gone.
