Small update on these, my buddy had a leftover cap and tasted it. Apparently there was an overwhelmingly obvious presence of... flour. Sad as it is to say, this makes me have to revise my verdict (for at least our batch of capsules, plus god knows how many more...) from "methylone" to "methylone cut with flour." While it looks like the actual dose will forever wallow in anonymity, I thank dear sweet newborn baby Jesus there was at least enough to feel something from.
Somewhere along the distribution line, someone really decided to get their asshole on. I only pray that karma sends a bus their way. Or better yet, a super dose of doXX sold to them as acid, followed by a bus 24 hours later, so the last day of their life is utter misery.
