How Long Does It Actually Block Opi’s For?

Ive seen a lot of different answers to this question, but mainly because most people get more than 1 shot. And doctors generally tell you its a “28 day/1 month long injection”, but I believe it actually actively stays in ur system for more than that

I got ONE 300mg shot on the 5th of December 2025, I was on subs for about a month before that (approx. 24mg/day). Stopped subs the same day I got the injection

How long can I expect the bupe to ACTUALLY block opioids for? At what point does the full feeling/euphoria come back?
