#injection-technique 2025-07-23

Reminder set. I will post here in 8 days.

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

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

does injecting a cold vial hurt more or am i imagining it

45 degrees

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

is bruising more about the needle or the aftercare

small bubble is fine

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

mark it down

is a small air bubble in the barrel a problem subcutaneously

absorption differences between subcutaneous sites are small for a weekly compound, thats just me

thats a reaction

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

31G 8mm

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

let it dry

not a problem

update from 22 months ago: switched to a fixed rotation and the site reactions stopped

for the archive push slowly. fast is what causes the ache afterwards, happy to be corrected

warm it first

technique probably

thats normal

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