Either you live in a country with much more liberal drug laws than the UK or US, or you are a bit misinformed. These countries have very strict regulations on who can possess quantities of scheduled narcotics, even for research. It took nearly a decade to get regulatory approval to schedule a MDMA research study in the U.S. It's hard to find source on this stuff, but you can see as noted here: http://www.newscientist.com/article/dn22280-a-real-fmri-high...
Exactly. Desoxyn is brand name for dextro-methamphetamine, the CNS-active stereo isomer. Levo-methamphetamine is found in those little Vicks nasal inhalers you stuff in each nostril to clear your sinuses.
