Prepping Fentanyl Solutions

[Kronos]

Yup i'm experienced with propylene glycol, its used in medicine also for making IV mixtures, just get USP food/pharm grade online, its everywhere and thats the grade you need for injection (i'm pretty sure)

Kewl. Was thinking it was food grade. With benzo powders it's probably better to go the solution route even if it ain't phenazepam. I was alright with diaz powder but that's pretty forgiving dosewise, the single-digit dosed varieties seem to be just a wee bit iffier for eyeballing. Just a bit

How long a wait after fent is it before i can take my subbys?i know its longer than 8hrs from past mistakes!

Also, if itake a tiny tiny dose of subs, 0,2mg or something, is it still enough to slam me into precipitated withdrawal?

I don't understand the whole precipitated withdrawals thing. Surely if taking subs knocks the opiates off their receptors (causing withdrawals), surely at that point you can just take more subs and they'll then bind to the same opioid receptors and all will be well?

Good question, curious. As I understand it, buprenorphine has high binding affinity but low activity. So µ receptor activation is not an on/off thing, different agonists can activate the receptors to different degrees. Bupe does have some opioid effects but it's a much weaker effect than heroin, for example.
