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.
