It's sticky and brown because of sticky tar-like impurities that the lazy chemist who made it didn't bother to remove. Composed of saffrole/iso-saffrole and other crap.
(From the chemist's perspective, why would he remove impurities before selling it? that just makes it weigh less!)
It can be removed by doing an acetone wash, but that also removes some of the MDMA.
Am pretty sure the brown sticky is saffrole which mdma is made from,dnt know

i remember reading a lab report from a guy who had crystals similar to yours, and he ran it through a gas chromatography process to find his product was 96.5% MDMA, 3% MDP-2P, and .5% of other various impurities.
