#injection-technique 2025-05-08

is bruising more about the needle or the aftercare

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

do you count to five before withdrawing

mark it down

sorry to jump in how do you avoid hitting the same spot twice when the marks fade

do not reuse pins. it is not about sterility so much as the tip being blunt after one pass

Inter-lab diff for lot C-4402: 98.1% vs 99.2%. Within expected range.

i keep the sharps bin next to the fridge so the whole thing happens in one place

do not aspirate for a subcutaneous injection, there is nothing to aspirate for

not a problem

i inject the back of my own arm and it is awkward but doable with a mirror

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

bleeding a little means you nicked a small vessel. it is not a technique failure
