Salt?
Had good results using a 2:1 as well. 2000g of lye per kilo is alot, but works (yeild 1.2% 1st pull). Base doesn't hurt the DMT, or so heard. But have to clean it afterward.
The pKa of DMT is 8.68.
The pKa of Mescaline is 9.56.
basify the crap out of mesc extrations and have good results!!!
The bridge between goals and accomplishments....Self-discipline.
