^ yes mate - spot on.
If it's translucent/white crystal it is as prue as you can get it.
OK it might contain some 5-meo-DMT too, I'm not sure - I've read that around 2% 5-meo gets extracted even using naptha, so it's still slightly jungle, but not anything like when you use xylene or limonene.
I say this because if you cleaned it enough, 5-meo would be white too - anything crystallized and pure will be translucent or white - simple.
Looks like you just been doing your extractions very well man, ^ nice one, I'm still learning, have decided to use lighter naptha for recrystallization from now on, after a DIY vacuum filtration.
