Opioids "Cleaning" dirty street fentanyl

[PetrolPete]

Gday all - recently relapsed and looking for some advice. As stupid as it seems while pumping poison into my veins, I really try to be as 'clean' as possible with all this; proper disinfection, clean tools, site rotation, etc. In years passed, I was able to source reasonably pure fentanyl with pharmaceutical filler from overseas. Now I'm dealing with a semi-local person and while consistent, I have no idea what kind of filthy garbage is being put in this stuff to stretch it. It LOOKS dirty. I consider myself lucky to be connecting high enough on the "food-chain" to entirely avoid xylazine/tranq and not be dealing with street-level people, who will put ANYTHING in there to make a buck. But it's still really dirty.

I remember a chemistry major buddy of mine who described a set procedure to "clean" street cocaine using solvents and the like, and all I want to know is: Does some similar procedure exist for fentanyl & fentanyl analogues?



My SINCERE THANKS in advance for any advice or recommendations!
