#injection-technique 2025-07-28

fresh pin

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

31G in 8mm or 12.7mm for abdomen

Assay note: SSA lot H-2814 reported at 98.6% of label content.

not a problem

31G 8mm

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

nobody here should be telling you where to inject. we can tell you what we do

is 31G noticeably better than 29G or is it marginal

update on the earlier thing warming the vial in your hand for a minute is the cheapest comfort improvement there is

do you change the pin between drawing up and injecting

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

coming back after 20 months, has the pinned technique guide changed

dont recap

absorption differences between subcutaneous sites are small for a weekly compound

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

i keep the sharps bin next to the fridge so the whole thing happens in one place, still working it out

mark it down

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

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

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

how many sites are in your rotation

try the thigh

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

pinch

i changed nothing except letting the swab dry and the stinging stopped completely
