Do I really want to tell this? Probably not, but everyone probably already knew anyway so who cares...
These "MDMA pills are getting different" stories are bullshit. I have used a lot, weight out a lot for other people and have seen a lot of different
reactions to the compound. After many usages the user does respond differently. I don't even consider taking it anymore, I only experience the
(negative) side effects nowadays, no way around it.
First time? 80 mg is nice and fun and everyone is in heaven, second time, 90 does the same. After thirty times better take something else, because
yes, you fried your brain. Doesn't have to be bad, but you did fry your brain. There is a Dutch case of a guy taking 3000 mg a day for ten years, just
to stay normal. In the end he was normal.. You get used to about anything and MDMA is one you get used to easily.
Summary: it is your mind telling it could always be so good. A minor spike on a NMR spectrum is an impurity, and not a active one.

in another way... as i know, different polymorphism tend to yield in bioavailability issues. (https://www.sciencedirect.com/science/article/pii/S209580991...)
If we assume that new synthesis give new byproducts and maybe new polymorphic crystal, this may change some things...
need more data.

That is for poorly soluble compounds. MDMA dissolves like a charm in the stomach and after that all crystal structure is gone.
This compound is structurally as simple as it gets... I really don't believe it would be missed if something really changed.

That's the deal with unregulated products, Also when speaking with drug users, everybody is saying that "things have changed". At any time.

Very true.
And not just drug users.
My great-grandmother always insisted that deer meat just don't taste the same anymore.
She blamed the advent of jet aircraft.
She and many of her old pals insisted that the noises jets make scare the animals and make them taste bad.
People can get mighty creative justifying their disappointments.
I once tried suggesting to her that the deer that she was shooting in her back yard probably didn't quite have the same diet as the ones she used to
get in the woods, but she insisted it must be those durned jets.
(She was like 90, and couldn't get around too well anymore, so she'd leave kitchen scraps out for the deer, and shoot one every month or so.
She'd brace her gun against the wall to shoot, and she'd drag it up on the porch with a rope to butcher it. )

Well, but high levels of stress hormones really make meat taste bad, and deer is easily scared.
Your great-gram might be onto something there.
Of course, diet matters a lot too.
Nonetheless, your great-gram sounds like quite a women

its probably due to the formation of optical isomers which have slighlty different effects. for example, you can buy
levo-MethAmphetamine at any drugstore without perscription for around 3 dollars. even though its physical properties are exactly the same as
Methamphetamine, its isomerism still exibits differnt effects.

It is either racemic or chiral, not something in between.
No one makes chiral MDMA, too expensive and requires too much effort, while providing a inferior product.
It is always a racemate.

What about the ratios - is it 50/50? And if so, is it always?

Yes, a chiral compound produced from achiral precursors will always have a near exact 50:50 ratio of isomers because there is nothing that can break
the symmetry:
http://en.wikipedia.org/wiki/Symmetry_breaking
Usually this is the case with MDMA production because the chiral center is fixed in the last step (reductive amination) unless the bromosafrole
technique is used, in which case the chiral center is fixed when the carbanion is protonated. Enantioselective catalysts or exotic precursors are
necessary to achieve enantiomerically enriched ecstasy.
The one other thing I can think of is that if MDMA is produced by methylating MDA (particularly via the benzaldehyde/MeI method) it's possible that
some amount of MDA would remain in the final product and affect the experience. This could be unintentional and may result in a stronger
experience than MDMA alone. The assays you've provided have low confidences e.g. 85% purity which leaves plenty of room for an error like this.

Is everybody skimming over the fact that...i'm transforming into an idiot?
But seriously, how can MDMAs neurotoxicity be ignored here? Your users' anecdotal reports of declining quality may very well just be, like Tsjerk
already said, effects related to neurological injury from regular use, quite possibly exacerbated, but most likely not attenuated by polytoxicomanic
behaviour.
As long as you don't provide full substance profiling of the good ol' stuff vs the meh new stuff, including analysis for synthetic pathway specific
impurities, where do you think this discussion is gonna go other than into a torrent of pure and ultimately meaningless speculation?
I mean, look at this:
It's always 50/50 in racemic syntheses and never 50/50 in asymmetric syntheses. You could have known that if you had wanted to.

2 new NMR were posted. The file ending ...207.pdf is confirmed magic, and the file ending ...579.pdf is confirmed meh.
On page 37 onwards there are reference 1H NMR plots.
The magic sample (...207.pdf) seems to match the reference MDMA HCL in D2O (page 45)
The meh sample ( ...579.pdf) appears be closest to MMDA base in CDCl3 (page 44). Not a super close match but I think its the best on my initial look
The other meh sample (...312.png) perhaps is also closest to MMDA but even less good a fit
So the big differences in the <7ppm range are: magic - peak around 4.87 (missing integration value?) that is not present in the meh sample. meh -
big peak around 3.70 that is missing from the magic sample.
MAgic sample...

stoichiometric_steve It's def not excessive use, because we LITERALLY change batches and BAMB it's hits us.
MDMA virgins, drug virgins, Heavy users....
So it can't be effects related to neurological injury from regular use, quite possibly exacerbated,

4.87 seems close to residual solvent signal of D2O, could be shifted due to pH effects of the ammonium salt. 3.7 in CDCl3 could be the NH on the amine
itself. Can you attach them as a PDF? I'm not going to register at some site just to take a look at the NMRs. Also remember NMR is only sensitive to
about 1% impurity so it's not going to tell you much.

Sigmatropic: that's a really big peak for a residual solvent signal.
What I can say is that those two NMRs show different compounds :p
EDIT: the following analysis should have the warning that reading NMR is not exactly my strong suit
If I were to guess, the peak at 4.9 is the benzodioxole O-CH2-O shift. A carbon alpha to an ether increases the chemical shift from 1 to 3 ppm so at
an acetal you might see something around 5 ppm. It's pretty rare for any moiety to have a peak here -- the only other thing is an alkene, which
shouldn't be present. The high peaks are the aryl hydrogens.
Moving forward with this theory, the absence of the 4.9 peak in the second sample indicates that the "mehDMA" does not have a benzodioxole ring. Based
on the descriptions of effects and the ability to simulate MDMA on test kits I suggest that the mystery compound is something like
3,4-dimethoxymethamphetamine. The "extra" peak around 3.7 is consistent with a phenolic ether, methinks.
Possibly, compounds like this are being introduced into the ecstasy supply by high-volume drug traffickers because they are cheap to produce and known
to fool colorimetry.

This reminds me so much of drug users who speculate again and again if their meth contains either this benzylamine derivative or "it could be 4-MAR
bruh!", when it is either bad or good...
They just talk shit and know nothing.

4.87 is the residual solvent signal of D2O i'm told by the NMR...
That 3.7 is what is a huge mystery thou and is in BOTH meh sample MDMANMR and file 78985

What atara says has hand and feet.
It is not MDMA what you see on the other NMR, it is another substance, likely the 3,4-dimethoxymethamphetamine he suggested.

Check the 3rd MDMAnmr sample.
This was MADE from safrole, and was NOT CUT... this sample is what started this whole NMR/MDMA debate XD. This was non darknet, private supplier type
situation so it's def synthesis issue at least with a few/majority of the batches. We had the 3rd NMR looked at Bluelight and for all purposes it
LOOKS like MDMA... so like meh i give up until we get more data

The magic sample looks just like the reference NMR plot from this paper: https://academicworks.cuny.edu/cgi/viewcontent.cgi?article=1... However, they mention something about 4.5 - 4.7ppm being a peak from the water
used in the sample prep. So should that be ignored? How come it isn't in the other two plots?
