"This sound right? I've had retatrutide sitting in my fridge for 3 days now because I'm scared to use it. I'm more so worried about long term side effects or buying something that is not what it claims to be."

Patient · Semaglutide · r/Semaglutide · Country not specified

"I have zero side effects aside from a bit of heartburn. I now have to tell myself to eat and the best thing is that I have absolutely zero desire for sugar. I was gonna eat some ice cream the other day (90 degree heat) and it tasted awful."
