Anhydrous means 'no-water'. If water is present, then you can expect to get crapola. Procedure: This first step can be done ahead of time. Like, during a distillation or reaction: Get a fresh bottle of 91% Isopropyl Alcohol, and pour out approximately 100mL. Now get some of your DRY Magnesium Sulphate (Epsom Salts) (about 100mL worth) and dump it into the 91% IPA. There might be a little heat evolution, but not to worry .... Shake it up and then let it sit till the MgSO4 settles out. Pour off the IPA, and then put more fresh MgSO4 into it (about 100mL worth). Now shake the bottle and let it sit for 15 minutes. You must do this at least three times - It really is much better to do it four times - Why fuck it up now right? After three times you will have 'Dry' IPA. You can actually do this while you are distilling or waiting for a reaction to proceed. Make a mixture of 100mL 'Dry' IPA and 150mL Xylene. Pour it into the flask that contains the MDMA oil, and drop the stirbar in too. Stir so that the whole thing is mixed up real well - Now drip in Muriatic Acid slowly. Test with pH paper every 5 drops or so - keep adding the Muriatic Acid until the pH of the solution is 5-6 - or just barely acidic. Set up for vacuum distillation, and distill the solution, distill this with the stirbar in instead of the boiling stones - IE When the solution has reached a pH of 5-6 - Start distilling. Be careful not to let the solution get above 120°C - When a lot of the solution has boiled away, crystals will spring to life in the flask. Under vacuum, the solution should never get above 70°C. Filter these with a coffee filter, suspended over a jar - This gets the excess IPA/Xylene out. Scrape the crystals on to a plate and let the crystals dry, by letting the IPA/Xylene (mostly Xylene at this point) evaporate - this might take several hours - a 60 Watt lamp 6 inches (20cm) away from the crystals shining brightly helps. Stir the crystals to promote even heating. 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? If you have completed this, congrats. Fucking Fantastic. Now Teach Someone Else! If you do - we WIN! Dig it?

god bless you sir
