Some of these formulations have properties that manufacturers claim limit or block the extraction of pseudoephedrine and its direct conversion to methamphetamine. In this study, 3 commercially available pseudoephedrine formulations were evaluated for ease of extraction and conversion to methamphetamine using a common chemistry technique called the  one-pot method  that is frequently employed by clandes...

Main methamphetamine production methods used in Europe from Ephedrine and pseudoephedrine as precursors .

  There are many ways to make methamphetamine, and each has its own risks and advantages. In Europe, two main methods exist, classified according to the chemicals used as starting materials, known as precursors. PAUSE. ( TO ORDER EPHEDRINE PSEUDOEPHEDRINE, BMK, PMK, 4ANPP, APVP, MDMA, KETAMINE,ALPRAZOLAM POWDER, 2CB FLY, PROTONITAZENE AND OTHER NITAZENES, FENTANIL REPLACEMENTS FOR RESEARCH. For best Privacy and encryption contacts below: Signal:+919319668540,  Zhohouabiotech@zohomail.com, zhohouabt@tuta.io One method is based on ephedrine or pseudoephedrine which can be imported in bulk powder or extracted from medicinal products or even from ephedra plants. This method is hazardous and difficult to scale up; in Europe, it is mostly used in small- to medium-scale ‘kitchen’ laboratories in and around Czechia, where precursors extracted from medicines are typically used. This method produces the potent d-isomer form of methamphetamine ( d -methamphetamine ( 1 ). The other method...
