But a smaller fraction.
If you’re paranoid, route it via the UAE. All my European and Indian shippers are doing that for tariff-free pricing. (Personal stuff. I’ll pay a customs duty if I get it, of course.)
So why not.
Why travel? There are thousands of ads on TV, radio, and the internet each day for Canadian pharmacies that promise to ship whatever you need to the U.S.
Realistically the cost of semiglutide in generic form means you could fly return every 90 days (personal import restriction for perscription meds) and still save $1000 every 3 months (3x$500 monthly - return flight - generic cost).
Multiple doses can be mixed and stored in the fridge for 4-6 weeks.
You probably have to disolve it in very clean water in a very clean container. Do you have to match the salinity and pH with the proprties of the blood? How much time must you stir it to ensure it's completely disolved? Do you have to add something to increase/reduce viscosity? Some alcohol in case there are a few bacterias or improve solubility? How long does the small homemade batch last in the fridge?
IIUC there is another version in pills, they may have a longer shelf life, or not. But ask a medical doctor before taking a ramdom medicine.
(Honest question. I don't know.)
I bet many Americans would travel to Canada to buy it there (despite the legality concerns). The medications lasts 2 years in a refrigerator.
