I have a custom all natural tek that has been working very well for me and am thinking about starting to vend. I am very experienced at OPSEC and the whole process so that will not be a problem. I am thinking about charging $50-$60 a gram. It is slightly lower quality and contains jungle spice. It is pretty pure and works very well and I will be sending part of my next batch off to get lab tested.
No, just do the final step and wash your product... It's just lazyness if you don't IMO. DMT extractions are easy peasey
