Thank you for your welcome Pandora!!
No, in my attemps I never have succes.
I tried Q21 tek with Calcium Hidroxide and never have succes.
I follow the instructions step by step.
I first think I dont warm the naphta at the right temperature, then I think my crumble MHRB+Calcium Hidroxide+Vinegar consistency are wrong.
I tried little variations trying to correct my mistake in case that I have any, but without possitive changes.
Finally when y review the steps I follow, my Naphta never precipitate anything and just in one occasion when the naphta was evaporated a little transparent coat gooey thing appear, but I think that was not DMT.
I still have 100gr of that MHRB, I acquired in the only smartshop in my country, but I doubt the origin, even when that smartshop have a good quality in seeds, salvia and other things.
Im still with the doubt that maybe the MHRB is good buy my tek attemps are wrong. But who knows?!
And yes, I was smoke freebase, yellow color and a good potency, buy not from my own extractions.
Making a research I found the tek's very easy in theory, buy I have no succed at the moment.
The MHRB notice was very bad for the world, thats for sure :/
In my country we have a good amount of Tepezcohuite, we found tepezcohuite bark (not root bark) in practically any local "mercado" (street market) I'm sure I can find a good source, of root bark If I spend the right amount of time in it! just matter of time for me!!
Finally, yes, I have psychodelic experiences before, with Mexican shrooms, peyote, salvia divinorum and lsd. I also tried bad drugs like coke, heroin and stuff like that.
In DMT terms, I just smoke changa, dmt freebase (white and yellow) and 2 days ago y tried Paganum Harmala with smoked freebase. A very curative secion for me. A very little visuals compared with only freebase, buy in extreme curative, with purge and all.
Actually, for 3 or 4 years from now, i just smoke self grow cannabis and dmt.
And for personal information: I have 30 years, spend my time painting, designing and sleeping
I do a little tattoo and I love Graffiti!
