I would recommend performing a full spectrum tek such as a BLAB tek, or using q21q21's 1st tek with d-limonene and salt with FASI. Its worth the extra wait/trouble, because the bark is likely to have oxidized a decent amount, so using xylene/d-limo to pull out all of the oxide is probably the best idea.
Oxide is very good. Theres nothing wrong with it. It will also pull any of the white n,n still contained within the bark, as well as jungle. Its great stuff man, id highly reccomend infusing some caapi with it, or some harmala changa, but thats just my thing
Electric sheep is great if you want a more normal spice experience.
If you dont want to wait for d-limo which can take a while to reach your door sometimes, and you dont care if its foodsafe, try performing q21q21's 1st tek with xylene, and either salt with fumeric acid saturated acetone and collect very clean fumarates, or salt with vinegar/hot water, and evaporate with a double boiler to recieve full spectrum goo.
The vinegar works well, if you dont care about having fumarates for long-term storage, and just want some changa to smoke, you just evaporate all of your vinegar pulls in a double boiler, until you can mix it around and smell absolutely no vinegar in it. Then throw in herbs and youve got yourself some very potent changa.
Let us know how it goes bro
