Bought the research chemical drug 'Methamnetamine' NOT methamphetamine or crystal meth: note the 'Netamine' not an amphetamine at all. A structural analogue of methamphetamine (not fuctional just structural). Snorted a bit over the week and now my nose has bloody scabs all inside all dried and painful! What caused this? Methcathinones or cocaine or MDMA never cause this to me and friends! What is this stuff?
