I'm using novorapid (humalog) right now, for injecting i've only used slin needles, with these I could inject IM because i could aspirate.
I've now got these pens:
It's not possible to aspirate with these, but I prefer IM injections, are there any ideas how I could safely inject IM with the pen.
Injecting slin into the bloodstream would be close to direct BG lowering right?
