Yeah, for me I’ve never used glucagon (though I’ve had lows bad enough to need it as a kid). So I think the purpose of this kit would just be to have the choice of mini-dosing when travelling, since that’s the main scenario I think it would be used. I usually bring the kit but forget to bring a syringe, since I use pens as a backup to my pump.
I should probably also find a way to reliably draw up 15-20 units, like making a notch in the syringe plunger or something.
If you put 1/5 of the powder and loaded it in a syringe - maybe the plunger sits at the 5 unit mark with the powder in it - you could then draw 20 units of the diluent into that syringe, back to 25 units on the syringe. Then roll it to mix, expel the air, and you’d have yourself a 1/5 dosage without spoiling the rest of the batch.
