#injection-technique 2025-06-07

anyone inject in the back of the arm on their own successfully

a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

90 degrees or 45

coming back to this do you aspirate, or is that only an intramuscular thing

whats your sharps disposal setup, mine is a jar and i know thats wrong

try the thigh

push slow

drawing up with the same pin you inject with is fine, it just dulls the tip slightly

the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small

let it dry

thats a reaction

i have eight sites and an eight week rotation. it is written on the fridge

30G in 8mm or 12.7mm for abdomen

sharps bin

fresh pin

follow up welts at the site are usually a mild local reaction and rotation sorts it

thats normal

how do you avoid hitting the same spot twice when the marks fade

technique probably

warming the vial in your hand for a minute is the cheapest comfort improvement there is

how far from the navel is actually far enough

small bubble is fine

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

sorry to jump in is 31G noticeably better than 29G or is it marginal

follow up 31G 8mm for everything. i tried the 12.7mm once and never went back

Reminder set. I will post here in 2 days.

rotate

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

a proper sharps bin costs almost nothing and pharmacies will take it back

never recap a used pin. that is how people stick themselves

Digest for the week of 2025-04-02 has been published.

90 degrees works fine if you have the tissue for it. 45 if you do not

does the injection site matter for how quickly it hits

is bruising more about the needle or the aftercare

do you pinch or stretch

absorption differences between subcutaneous sites are small for a weekly compound
