He claimed that this produces a mix of the two isomers and swears that those batches are much more sexual, as in you wanna jump at your partner and vice versa. Perhaps there is some kind of synergy between the levo and dextro?"Disclaimer: I'm not a chemist and not even a cook (no bullshit, never done it). That said, I've been around long enough to remember the Hive, and I just can't believe that would actually help the reaction along. I2 + H2O + heat yield HI, which reduces pfed to iodoephedrine then to d-methamphetamine. Start with pfed, end up with d-meth. The RP regenerates the HI to keep it going. RP/I2 shouldn't produce any l-meth at all, if what I've read is accurate (been awhile though). The only thing I can see the addition of zinc doing is at best nothing, and at worst inhibiting the reaction and leaving the cook with a dirty jar full of some meth, some iodoephedrine, and some unreacted pseudo. And however much zinc got thrown in to begin with.Honestly it wouldn't surprise me if that's actually closer to what the guy was after, in the end. If a mix of dextro and levo really is what grabs you by the dick like a vice and doesn't let go, I'd believe a dirty product would get you closer than pure d-meth. If my memory's not failing me here (and that's a big if), the anhydrous ammonia + lithium route yields a racemic mixture (not in the same proportion as P2P though).Of course, we could all just be full of it and a d,l mix may actually have fuck all to do with it. Supposedly l-meth has almost no psychological effect, but l-amphetamine does have some (smallish) effect. But you only get methylated amphetamine out of pseudo, no straight amp as far as I know. shrug.Apparently there're over 90 published methods of producing methamphetamine, so who knows what really does what, in the end.
