Ahh yes ice, i've done quite a few STB extractions and one A\B not sure which tek completely as its never my extractions. I have basic knowledge in Chemistry although my goal would be to become a organic chemist and engineer, i've tried quite a few psychedelics ranging from 2c-e and 2c-i an 2c-p to lsd,lsa,acid and of course shroomz and i just happen to be sitting on a bit of dmt right now. i've read your post on the insuffilation  of freebase i was wanting to conver abit into salt to make it more bearable but came to the conclusion without doing a FASA i'd have nothing but goop and i just dont wanna sell any of my deemsters cause  i couldn't trust anyone with not having a bad trip and snitching... we recently did a 84G MHRB STB extraction not too sure on complete yield but i got bout 2 grams for free.. but on another note thanks for the reply its been all day and your the only one who replied, maybe i didn't add enough information although i tend to be a reservist... so if you have anymore questions please ask i'm willing to answer!
