Not so simple man it does mean it's NOT PURE regardless of enantiomers because NMR showed safrole, MDP2POL and MDDMA when EC and others even my owns friend university showed pure.. But when NMR came into the picture out of every sample we tested only the MAGIC batch had a clean NMR the rest we tested didn't.
Why would you need NMR to distinguish MDP2POL, MDDMA, and Safrole from MDMA?
They are not the same mass so you wouldn't need NMR.
We can throw residual safrole out as an issue b/c it's been an impurity for decades and it falsifies the PMK-GLY hypothesis.
MDDMA is an impurity caused by synthesis of MDMA by methylation of MDA using methyl iodide, not commonly a route of synthesis. But I've probably eaten it.
MDP-2-Pol has also likely been a longstanding impurity of many batches of MAGIC MDMA over the years because you get there from safrole and some acid. I've probably eaten that too.
So you have a few batches with impurities that you have ZERO EVIDENCE attenuate the effects of MDMA. You don't provide mass fraction of impurities.
Were the samples pills? What mass of MDMA was identified by NMR?
You also have not identified the stereo isomer configuration of the (2, 3, 5) "impure" batches. vs 2 "pure" batches, and the only discrimination is subjective effect.
C'mon man. That's ridiculous.
I have never NEVER EVER in 25 years of eating beans had Meh-MDMA. I've had not-MDMA, I've had MDMA that was significantly cut, but in EVERY SINGLE BEAN or line of MDMA that tested reasonably clean, and reasonable concentration (yes WAG), and the correct dose THE MAGIC WAS ALWAYS THERE.
EVERY TIME
There was a period of time around 1999-2002 where I was associated with club venue and event management. I would eat whatever beans people gave me, beans security "confiscated" from dealers, gifts from patrons, literally 6-10 beans a week every week. So if it was in a pill I probably ate it unless it tested dangerous.
And I can guarantee I've eaten beans or powder that had MDDMA (used to get beans that were an MDA/MDMA combined press , safrole (root beer taste), and MDP2pol because backyard safrole reactions in the 90s. (your impurities)
I've eaten over 500 beans and at least 20 grams worth of powder since the mid-late 90s so if it's an impurity from an MDA or MDMA synth I've eaten it.
AND I have eaten beans and powder since then, all the way through to today.
SO MY SUBJECTIVE EXPERIENCE FALSIFIES YOUR HYPOTHESIS, namely identifying there is ONLY ONE actual DISCRIMINATOR between your 'meh' and not-meh --
personal subjective experience.
I've almost certainly eaten duplicates of you meh and it was Magical.
Which isn't science.
