I don’t use this but might be for someone out there who does, check it out?
The word I get is that it’s old-school insulin so the dose might need fiddling, but otherwise checks out. Have not confirmed personally. CVS is rumored to have the same thing going on, but that is currently unconfirmed.
Snopes has details. In short, this is, as @chemipedia hinted at, human insulin, which requires a lot more peplanning and management. You’ll need to talk to a doctor about using this stuff if at all possible. It’s still good to have the option over going without, though.
