Is it because they are taking it as a weight loss drug?
I think you are correct on that one. Most diabetics get 1-2 ml a week. I wonder if the “healthy” folks looking for a weight loss fix are ODing on the drug and screwing them selves up with it.
The Rx drug “Semaglutide” initially developed as a Type 2 diabetes treatment (”Ozempic”)...diabetic users found that it also caused them to lose a few pounds...the pharma company (Novo Nordisk) jumped on that and got it FDA approved as a weight loss Rx (”Wegovy”). Double the revenue/same drug doncha know!! ;-)
Off-label usage.
Very common with many drugs. Often with time becomes common usage.
Well - it does require a prescription - “Ask your doctor if this crap is right for you...”
