Testing the accuracy of my injection pens

[v2boi]

No there's sellers of the Eli Lilly and Novo pens on Ali. They have "not for resale" on the boxes, so I assume they are through some bulk buy government or hospital program.

They're usually on sale for about $18USD

The novo pen will require an adapter as a standard 3ml cartridge will not fit

the plunger springs back near the end of the dose if it's more than 10 units or so.

Could it be back pressure from the needle getting clogged or too small of a needle for what is being dispensed? Did you try going slower or holding it down longer?

It wasn't a force thing; it was like the plunging mech was slipping a gear.

Interesting.....I am in the US and all but one of these loads the correct pen and within a second I get a full screen message "These are not available to sell in your location" (or something similar).

I had the same problem. The pen keeps jumping back, so the next dose is not correct anymore. I threw the pen in the trash.

Yeah, same. I almost kept them, then realized why on earth am I keeping a pen that doesn't work? I pitched them, bought two more V1's, and I'm good. I don't need to have more than four peps on rotation anyway; that's tirz, survo, klow, and something else. If I think I need to be pinning more than that at a time, no I don't.
