Well I certainly won't be taking you seriously since you immediately resorted to calling me a retard instead of entering a sensible explanation of what was wrong with what I said. What kind of response did you expect after you directly insult me?
The fact is you get used to the sourcing if MDMA, seeing MDMA, testing MDMA, taking MDMA. Then you know what MDMA is. Don't let the door hit you on the way out...
Yeah. This convinced me...
I've done synthesis experiments at uni where I've had to conclude that seemingly perfect products could just as easily have failed horribly when testing with mass spectrometry, UV/Vis or infrared spectroscopy.
Next to that, I've delivered quite a few samples of drugs to get lab tested and for example: 2 completely different samples of amphetamine sulphate
color: Pinkish / Yellowish
structure: Sand like / More clumpy
smell: Strong, chemical smell / Less penetrant and fruity smell, like apple-ish
burn: Hurt a lot to snort / Barely noticeable
Both samples were first dried on a preheated surface, given an acetone wash and left to dry by room temperature before being tested and both resulted in 67% amphetamine without active cuts. (73% being a practical max and <135.21 / (135.21 + ½ 96.06) = 135.21 / 183.24 = 0.73788, 0.73788 × 100 => 73.788% theoretical max
All differences were most likely caused by that small percentage of impurities, but believe me, there are just a few producers in the world both honest and capable enough to produce anything over 70%, although they do exist. Therefore any conclusions based on anything but measurements should be considered assumptions and invalid unless confirmed. So they're basically just hypothesis.
People could simply add something with the same odor to something with the same structure, dyed the same colour... Fun fact, did you know both benzaldehyde (fairly safe) and cyanide (highly toxic), two completely different chemicals, smell exactly like almonds?
The aggressive tone is partially because it'd most likely be ignored when not actually being debated about, but mostly because it frustrates me that people act capable of analysis without equipment or even believe they are themselves.
Oh and I'd like to add that there are research chemicals that cause closely related effects. Almost indistinguishable.
