apart from solvent you told us nothing about the storage of the material.
I love these 'shot in the dark' question/answer problems.
Temperature, light exposure, container type and material, sealed?, acetone quality (store or lab grade?), storage enviroment.
So the iso distills at the correct temp (vacuum used in disto?) and you made it to mdp2p (how? what method? how did that go? correctly as per synth document indications?)
what colour was it? (this is interest based, as i said recently, the colour of mdp2p is varied and not reliable indicator in most cases).
Did you test with bisulfite? what result?
What grade reagents did you use to produce it?
What conditions were the reactions run at?
What equiptment did you use?
What was the shape of the cloud above your house at the time? (joke)
What process did you do to run mdp2p-->mdma freebase ?
(same questions for this as for mdp2p reaction question)
Jesus include details and set it out clearly, your post was bad and to hard to read, otherwise no one will care enough to read your post, little alone help.
