It's all over in Norway too. Anecdotally it is definitely more common than steroids already. I can only find statistics on the legal ones, but they show that 10% of all women in their 50's are prescribed the ones for weight reduction <https://www.fhi.no/he/fr/folkehelserapporten/samfunn/legemid...> (Fig 13).
I'd make a distinction between Semaglutide/Tirzepatide and other GLP-1 agonists that are available through the regulated pharmaceutical system with strong evidence for particular uses, and ordering unregulated peptides from China based on a subreddit's recommendation.
I used to be on a biohacking/nootropics discord a decade ago. People were trying to treat their depression by ordering research chemicals from Russian labs or synthesizing them themselves. Huge difference between that and going to the GP and getting a Prozac prescription, with semi-regulated supplements being in the middle. That's analogous to ordering peptides from sketchy suppliers, getting a GLP-1 prescribed by a doctor, and getting a peptide facial from a medspa.
I would assume that an order of magnitude more people are getting prescription GLP-1s than are ordering other peptides from online suppliers and injecting them.
