recrystallization vs simple acetone wash

[MyNameIsNotWilliam]

Hello there bluelight.

A friend of mine has done alot of mdma in his past years. From sellers to sellers, he feels like the stuff he's getting isnt that great from times to times so he would like to make it cleaner. What would you recommend? Re-xing or doing an acetone +isoproalcool wash or both? Do you guys know anyone that has tried this and has good results? Is there more loss of product (MDMA) in the re-xing ? I've tried to run around and gather some informations but they seem somewhat unclear and never make a parallel between the two.

Thank you very much!:D

It all depends on your friends laboratory experience. If he is experienced and knows what he is doing, then the loss will be next to nothing and result will be high quality stuff.
If he is sloppy, don't really know what he is doing etc, he might loose stuff in the process.
Re-crystallising will get best results, but it's slower in terms of wait time required for the crystals to form. On my first try I did lose a dose or two as I messed up with the recrystall process and wasn't patient enough.
Acetone wash, on the otherhand is quite simple stuff. In my opinion with acetone wash there are two risky parts for losing the substance:
1) if your acetone is not ahydrous, then some of the stuff will dissolve to the liquid
2) when you are filtering the mdma out of the liquid, some of the stuff will be stuck in to the filter. in general, I think this is not noticiable, but I guess there is the risk of messing up here too.

Here is re-crystall instructions (Note to Mod: this is harm redction: I rather consume pure MDMA than one cut with unknown substances)

Here is instructions for acetone wash

Thanks for the very complete reply Mister. I just got in touch with my friend and he is not some sort of lab guys, but he did have organic chemistry class and did few liquid/liquid liquid/solid extraction before and he has chemistry class around the pharmacist level. Do you think he could do the re-exing method? He saw around that you could also use some sort of alcohol to help mdma precipitate since alcohol is more miscible in acetone than mdma is and would "push" mdma out of the solution.

Why are you asking for your friend? Also if you've had an organic chemistry class, you'll do perfectly fine at both a wash and recrystalization. If not, you shouldn't have been allowed in a lab anyway.

In my recrystallisation effort I used warm IPA (Iso Propyl alcohol) as solvent. (note, it's flammable, be carefull, don't use near open fire). Once I figured I had all of the stuff dissolved, I poured in excess amount of ahydrous acetone. According to the person who originally created those instruction images, the acetone will push out MDMA from the alcohol solution.

My personal experience was that the solution will hold up more MDMA than one would think. It took long time for the last bit of MDMA to come out of the solution. If I'd have lots of MDMA (5+ g), I would re-experiment. for smaller amounts (1-2g), I would not bother. Too much of hassle for me compared to the gain. MDMA crystal in these parts is very pure to start with, so the additional gain from reCrystal is tiny.
