While I'm all for saving costs, I would be shocked if mixing your own inject-able medicine either weekly (with the chance of making a mistake in dosage or sterility) or too such a high degree of sterility that you can confidentally store several doses is not worth the $200 return flight every two years. Maybe I'm overestimating the risks but it still seems like a small saving for it.

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).

Its remarkably straightforward. Not fool-proof, but easy. Bacteriostatic water, single use needles/syringes, and self healing injection port vials makes it simple to maintain sterility throughout the process.

Multiple doses can be mixed and stored in the fridge for 4-6 weeks.

While I agree and this all seems reasonable, I think you give the average person far too much credit.

it's extremely common. everyone i know that's on a glp-1 does it this way. that way you can buy it in bulk for a discount. i buy mine roughly 35 weeks worth of doses at a time.

How do they have confidence that the vials they're getting are sterile / pure / free of endotoxins / etc?

This is commonly done for injectable fertility treatments, though in my experience they are hydrated just before use.

If you live near the border, of if you regularly travel to Canada anyways, then the travel cost isn't an issue.
