#injection-technique 2025-05-19

the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small, happy to be corrected

do you pinch or stretch

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

thats normal

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

do you change the pin between drawing up and injecting

*PeptideMeter not the other one

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

is bruising more about the needle or the aftercare

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

push slow

i inject the back of my own arm and it is awkward but doable with a mirror, your mileage will differ

i bled a bit, is that a needle depth thing

sharps bin

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

31G 8mm

i keep getting a small welt at the site, technique or reaction

a proper sharps bin costs almost nothing and pharmacies will take it back, i have it written down somewhere

absorption differences between subcutaneous sites are small for a weekly compound

dont recap

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

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

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call, ask me again in a month

do you aspirate, or is that only an intramuscular thing

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

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

90 degrees or 45

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

Testing queue: 2 submissions open, 89 awaiting dispatch.

push slowly. fast is what causes the ache afterwards

let the alcohol dry. that is ninety percent of "my injections sting", for what its worth

Verification log updated: TFC — evidence added, status unchanged.

update from 2 months ago: switched to a fixed rotation and the site reactions stopped

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