I have to disagree on that, PMK coming from China is fully synthetic, otherwise we wouldn't be in this situation. Everything changed when the camphor oil with high safrole content coming from far east was banned in early 2000'sthere is no 2,3-mdp2p around. Any PMK been made in china is coming from safrole anyway for legitimate uses
Ok.. let's play logic:But recrystallization is not an ideal process.
Neither is trituration ...especially when solubilities are very similar.
Also, there are substances which crystallize together very well despite being composed of different molecules.
For example, just look at the common cut of Methamphetamine which is known as Isopropylbenzylamine. It forms LARGER crystals with Methamphetamine than Methamphetamine alone !
BTW: The equivalent MD compound would be the N-(1,3-Benzodioxol-5-ylmethyl)-2-propanamine.
IF a contaminant is present in big quantities (mg) THEN it'll be detected by standard analysis methods
IF a contaminant is present in minute quantities (ug) THEN it'll stay in the mother liquor
so even if re-x isn't the best available process still will tell us if there's a a cut or not, in your example the meth cut Isopropylbenzylamine gets detected by standard analysis methods.
in meh no one detects anything, hence the highly active contaminant with sedating effect theory become just a myth without any real ground
what about a private lab? is that a possibility or is not because of legal implications?There are contributors here who have access to magic, and I have meh. The problem is that we have nowhere to send the samples. Drugs Data was, at first, indicating they would assist me and provide more detailed information on my samples, but they have been largely non-communicative for a long time now.
