Refer yourself to the Jungle Spice article as I belive the term "Dark DMT" is outdated
Toluene and DCM to name a few others.. solubility of n,n-dmt in limonene works very well. If you could get yourself some d-limonene though, agreed to using vinegar with endproduct - DMT acetate. Not sure of the solubility of yuremamine in limonene though..
SWIM has experienced oral activity at quite larger doses of DMT fumarate(300-450mg) and even percolated tea's. These weren't necessarily amounted to the primary methods of inhibition(via inhaled vapor, insufflation, conjunction with harmine&co.) but very much in that head space. IMO, the purpose of the mystery alkaloid in MHRB is primarily for MAOI activity..
FASA tek precipitation will salt out all the goods very quickly & safely in petrol products, however I wouldn't say the same for d-limonene or naphtha.
Note to SWIY:: Mystery alkaloid is very unstable and an A/b extraction is recommended but not necessary. Aim for ph 9~
Also, check the wiki for Shaggy's jungle tek or entheogenists tek if fumaric acid is n/a. They may be of interest.
SWIM doesn't understand the reasoning behind the separation as SWIY will find the end product to be very rewarding, but the Yuremamine degradation project is very intriguing and under wraps atm.
