Im stuck on deciding which i should do so i can go buy materials. I heard Q21Q21's has more pure DMT (which is important to me) but what are the yields? I know Noman's yield around or a little less than 1% but what about Q21Q21's?
Thanks!

you cant say noman will be around 1%, it all depends on the bark.
If you are doing an AB then the consensus is that the spice is cleaner that a STB
But plenty of ways to purificate the spice after a STB ( sodium carbonate wash, dissolve in hot heptane, ...)
imho both methods should more or less pull the same amount of dmt.
STB being a faster and more impure method than AB

Thank you for the information! I think i will do the A/B tek because it is more pure DMT and i wont have to do recrystallization (maybe once or twice but the DMT should be pure enough (barely any yellow) for me).

Q21Q21's tek is faster by far than Noman's, unlike many other A/B's.

Q21Q21's tek #2 will leave you with a very pure product. It's also easy, safe and cheap. Both will pull pretty much all of the DMT from your MHRB. In many cases, q21q21's will result in some solvent loss, which will leave about a dose or two trapped in your MHRB. Getting around that is a matter of practice and paying attention.

Side note: Keep flammable liquids away from your stove if you use the latter. Use hot water or an electric slow cooker on low. It's also much nicer to use a 3-4 hour acid and base stage, In my experience.

Q21's should yield all you've got in the bark. I've heard of even 1.7% yields with this tek. And it's of course smarter to go A/B than STB for the sake of purity.



Why do you feel so? I agree about the basifying step, but why the acid step?
