is there any reason to warm the vial in

cold from the fridge genuinely stings more. i let it sit out for ten minutes

fresh pin

i mark the rotation in a notes app because the marks fade and i lost track twice

mark it down

let the alcohol dry. that is ninety percent of "my injections sting"

push slow

thats normal

do you aspirate, or is that only an intramuscular thing

try the thigh

small bubble is fine

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

absorption differences between subcutaneous sites are small for a weekly compound

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

90 degrees or 45

push slowly. fast is what causes the ache afterwards
