There's not enough background here for a solid reply. Details on your age, starting weight, target weight, height, time using the medication, reasons for quitting, and any bad reactions before or after stopping would all matter.
Fourteen days later the amount in your blood should sit under a quarter of the highest point, or about half what shows up right before the next weekly shot. It clears in roughly six days instead of seven, so levels fall by half or a little more over one week. A graphing program can help map out how doses line up with effects and reactions over time.
Two weeks off probably won't erase any reduced sensitivity to stomach issues, so starting back at the prior amount or a bit lower if you had trouble before could work. I haven't seen proof that sensitivity builds to the appetite control or fat loss parts of these drugs, so a short break won't make receptors act brand new. There are signs that the first few months bring some adjustment to slower stomach emptying and gut reactions, with the worst nausea often hitting early then easing over time.
Dropping the amount only fits if you've already hit your target. If that's true then testing a lower amount and watching what happens makes sense; if weight creeps back or hunger stays high then going up again is likely needed. Long-term studies on keeping weight off point to staying at the amount that worked for loss, though plenty here manage it with smaller amounts.
I've been off it for two weeks now. How long does it usually take for saturation to drop? Is there any chance a lower dose would still work after a short break? I'm currently on 6 mg every five days and have already lost 25 kg.
