Thought I`d share this from the link rosecitypapa sent, +Rep buddy!
The crystals will be a brown-yellow color. Now scrape the crystals into a jar, and pour ~20mL of acetone onto them. Swirl the mixture. The crystals won't dissolve - but a lot of the brown will. The brown-acetone is poured off, and the acetone wash is repeated.
After the acetone wash, dry the crystals. You should have around 15g of dry crystals. That's 150 hits. The now 'almost white' crystals have melting point values over the range from 145-153 ° C, depending on how much water was in there during crystallization. And these crystals are ready for consumption. 60mg is not enough. 80mg is great for my wife. 100mg is a great dose. 125mg is balls-to-the-wall. 150mg is too much. For me at least. Fun for me is actually 80mg MDMA+70mg MDA in one pill. WHOH. But I guess you'll have to do another synth - right?
I`m going to get some Acetone to clean some stuff of my room walls prior to inspection, might give 200mg of crystals a go and see how it works out... Handy info to know though thanks!
