MDMA crystal lacking potency?

I recently got some tested MDMA crystal (more like off-white rocks) after years of not being able to find any. Did it on two separate occasions w my gf. 1st time we each did a .18 and we were both quite underwhelmed. Three months later we did a .28 due to suspected low potency. We rolled but it was still not what I remember MDMA being when I first dabbled in it back in the day.. no overwhelming euphoria or ‘wow factor’ no crazy tactile enhancement, music just sounded a bit better. it was just alright. Very mild eye wiggles and some jaw clenching. Next time I’m thinking about upping the dose to a .35 or possibly higher to achieve desired effects. Anybody have any input here or have a similar experience ? For what it’s worth the substance itself did feel extremely clean and we both experienced the same effects off identical doses. No harsh comedowns, pretty smooth come ups, and no depression in the following days.
 
I'm big and fat, I take ~250mg and that's quite a lot, 350 is a shit load.

yes it might just be impure so you need to up the dose, but get it tested, might not be MDMA, might be a cathinone

Did you test it yourself and how was it tested?

Because I agree with @placebonaut sounds like it could* be something else because even 180mg is a fair amount.

If you're doing reagent tests, I would use more than 1 type of test. Marquis, Mandellin, Mecke followed by a Simons.. MDMA tests very dark with most common reagents and can overpower the color reaction of different substances. Start with a Marquis reagent and watch very carefully for any flash of yellow/orange before it goes purple. Its somewhat common for MDMA to be cut with cathinones.

I don't think anyone here would advise you to take 350mg or more.
 
MDMA isn’t the same now it’s fully synthetic.
MDMA in the 90s up until early 00s were made from safrole. The crack down forced chemists to find a new precursor - PMK, and a different synthesis route which i think has messed up the isomers, stereoisomers and has caused polymorphism.

Old Es that have been tested back then were dosed from 90mg to 180mg of pure MDMA
one or two had MDA in and MDEA in. Some a bit of speed and caffeine but no silly 300mg dosed Es
Just properly made MDMA.
This “new gen” MDMA has no come up, no tingly rushes, not much empathy for me either, just a sort of forced euphoria.

Repost from another thread I just made:

I have some updates that I think will be useful to this thread regarding Mehdma.

So last night I took some from the same batch mentioned in my previous post. 300mg of this batch absolutely did the trick for me and 280 for my gf put her right up there with me. This is only her third time attempting to roll for the record with this one being a successful breakthrough. First two times were underwhelming compared to this. Man.. I completely forgot how awesome this medicine is as well as the experience. I will say again, this is REALLY clean M. Roll lasted for about 6 hours in total.

My conclusion for Mehdma in my case was having crystals that were ‘watered’ down and needing to basically double up the dose to achieve a breakthrough roll. I’d say the .3 I did last night was more on par with a .15ish of some pure crystal.

Keep in mind, I’ve never abused mdma or similar drugs. The only real rolls I’ve had is my first one back in 2014 and last night. Our last time attempting to roll was from a rather popular online vendor with 5mapb. We each took 125mgs and that was underwhelming.

I don’t know if I am articulating this well because this is the day after and I still feel out of it so bare with me plz 😅

That's a shame you stumbled on to watered down MDMA crystals.
I do want to point out that 120mg of 5-MAPB is considered a strong dose but I'd also argue that it just hits differently and I personally prefer MDMA over 5-MAPB any day of the week. In any case, you might be a bit of a hard head...

It honestly is, but I’m assuming whatever they’re cut with is just for weight or there may have possibly been an error in the production? Idk I’m no chemist lol. I talked to the person who sold it a while before I decided to jump the dose up that much and he said 9/10 people were saying the same thing I was. But besides that the experience/product itself was very very clean and I cannot stress that enough. Got the calendar set for another 4-5 months out :)

Yeah wasn’t too big on the 5-MAPB tbh. Didn’t really have any euphoria from it. Just made me lazy and feel heavy. But as far as the dosage choice for it I just followed what was on the packaging and read others recommended doses for it via another popular forum site. Tbh I don’t think their doses are quite accurate either.

Yes I may be a bit of a heard head :) but I knew that there was potential with this mdma lol I just had to find the sweet spot for this batch

Also should of mentioned from your original post that it was indeed tested in front of me at the original time of purchase and everything checked out
 
also no chemist. but making MDMA is a process, there are a number of errors in the steps needed that can reduce yield and a number of different ways to make MDMA

you mentioned color already which sounds right, white to off-white, sometimes a bit beige.

smell is another, pure mdma shouldn't smell burnt, maybe faintly of ammonia iirc when you grind it

large clear crystals/shards rather than powder or clumps of micro crystals

I think contaminants/crap left over from these production errors might be a bit of pain to wash out too so provided the batch is good enough they will just ship them with reduced strength. The worst 1 is where there's thermal degradation but that's going to produce more strong and darker colors and is effectively a failure, it's a through it out and start again mistake.

not sure the other fuck ups are too dangerous, just reduce yield and therefore strength.

as always, titrate up is your friend....dab it till you get there, or butch up and bump it, then next time you'll have a better idea how much is needed.
