15mg???? That is absolutely insane if it is Semaglutide. The vials I sell are 5mg / vial, 1 vial lasts me about 4 weeks and I do what is considered a very high dose, doing 3 vials of that in one week is just mind blowing to me, you must have confused 15mg/week with 1.5mg/week.
Please reduce your dose immediately
