Are you or is anyone you know "immune" to MDMA (and similar RC chems)

I am positively immune, I've done DOZENS of experiments and I've finally just accepted it.
Luckily psychedelics with friends give me massive euphoria.
But no matter the setting. No matter the dose: Micro, Low, Medium, High, Really high.
Taken in combos with tons of things, titrating dosage up over several days, MDMA and 6 other similar chems never did really.

I DON'T want help with this, I am perfectly okay with it and I am thankful that I can let go the mystery. I've got euphoric effects for 2-20 minutes like 10 times or so which led me to believe there was a solution and I spent so much effort and money on it.

Anyway, I'm just asking out of curiosity.

A few people are really naturally tolerant to phenetylamines, but ive never heard of someone being completely immune. What dosage did you try, maximum? How sure are you that it was mdma, and pure? How did you consume it?

well the ratio of active to lethal dosage is 1:16 for ecstasy, but i imagine it was MDMA and the study just put e, so i would say you can go about 15x as high as just under a low dose.
any more than that would probably be.... unwise.
not to say 10x a low dose is wise...

I've tried as max:
400mg MDMA
650mg Methylone over 1 hour
500mg Mephedrone over 2 hours
400mg Flephedrone over 2 hours
700mg MDAI over.. I dunno
300mg MDA in a night

I know those are MASSIVE and careless but after a point (like 1.5-2x regular dose) I just feel sober with a little buzz. I ALWAYS stop when there are any negative side-effects and document each dose.

but on each of those mentioned there were no significant physical side effects, in each case the hangover was lame but not depressive, with the exception of the MDA which there were many variables around but had a NASTY hangover.

So ya, I just threw out all my stuff except my harmalas, my DMT (and MHRB) and some MDPV
The MDPV I am trying as a test, daily low dose for a week or two, see if I feel any benefit. it is simply a DNRI which I can get without a prescription that should have similar effects to adderal, ritalin, dexadrine, welbutrin and junk (from what I have read)
If it does turn out to work out then I will strongly pursue one of those much safer ones I just mentioned.
If not then it will not be a suprise, nothing really does what it is suppose to with me. I was really obsessed and very I-BET-RITALIN-WOULD-WORK! and kinda obsessed with it for a while.
I know they are different but I know that I react similar to phenethylamines and tryptamine or different varieties so I'd bet if MDPV don't work, it is unlikely the other would.
Also with that reasoning it gives me an excuse to fucking stop using drugs!
