I came to the same conclusion about crystal Mamp. Despite appearing as large nearly pure crystals, which should be absolute rocket fuel, a large percentage of the “super lab” stuff from mexico does not deliver the Go that pure amp should… people might call it “sleepy m” or whatever… I have investigated cuts/adultrants thoroughly, as well as the chemistry of common manufacturing processes… note: ineffective amp tests pure on a immunoassay drug panel AND by GC-MS/LC-MS. This mystery has resisted explanation for years… I concluded it must be a polymorph… maybe the preferred chemistry of synthesis at an industrial scale has changed… If somebody knows better, please tell me what it is…

So methamphetamine was largely made via reduction of ephedrine and/or pseudoephedrine to methamphetamine, typically either by a Birch reduction or via the Nagai Route involving red phosphorous and iodine. The latter had a conversion yield of ~75% and the former, ~92% if performed correctly. Mexican "cartel" super labs initially imported Ma Huang (the ephedra plant) from China and made meth via ephedrine reduction to meth after extracting ephedrine from Ma Huang. U.S. DEA started blocking these ships in the ocean, so the cartels change to a P-2-P route which produces racemic 50/50 d-to-l-isomer meth. Then they learned how to resolve the l-isomer to a new racemic blend, and they resolve again, repeat the cycle a few times for added purity, and then ship it.

The most common cut with today's superlab meth is l-isomer meth. Sometimes MSM is found, but it's not as common as some ppl seem to think it is, plus it's easily removed through pre-application to heat…
