- triple_ag_tom — my rotation, taped inside the fridge door 21:19
- batch_bandit — it matters eventually. lipohypertrophy from repeated subq into one patch is a real thing 21:24
- stack_sceptic — because that is what came in the box 22:01
- batch_bandit — until it is actually dry. go in wet and you drag alcohol into the puncture and it burns 22:20
- batch_bandit — it always is. the first one is the hard one 23:13
i mark the rotation in a notes app because the marks fade and i lost track twice
right so push slowly. fast is what causes the ache afterwards
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
i changed nothing except letting the swab dry and the stinging stopped completely
whats your sharps disposal setup, mine is a jar and i know thats wrong
where does everyone actually inject
abdomen, about two inches out from the navel, either side. that is the default
front-outer thigh, upper outer buttock, back of the arm if somebody else is doing it
arm on yourself is doable but you end up at a stupid angle
i do abdomen and thigh only and rotate it like a clock face
my rotation, taped inside the fridge door
week 1 left 2 o'clock (abdomen)
week 2 right 10 o'clock (abdomen)
week 3 left 4 o'clock (abdomen)
week 4 right 8 o'clock (abdomen)
week 5 left upper thigh
week 6 right upper thigh
then back to week 1
rule: never the same square twice in six weeksdoes it matter if i just use the same spot every time
it matters eventually. lipohypertrophy from repeated subq into one patch is a real thing
and absorption out of a lumpy patch is not the same as out of fresh tissue
noted
pinch or stretch
pinch if you are lean, stretch it flat if you have tissue to spare
with an 8mm 31G it honestly barely matters. you are not reaching muscle either way
12.7mm is where technique starts to count
why is anyone using 12.7 for subq in 2026
because that is what came in the box
cold vial straight out of the fridge stung like hell
yes. let it sit out for ten or fifteen minutes first
or hold the barrel in your fist for a minute after you draw. same effect, faster
the sting is mostly the benzyl alcohol plus the temperature. warming helps both
how long do you leave the alcohol swab to dry
until it is actually dry. go in wet and you drag alcohol into the puncture and it burns
count to fifteen. that is the whole trick
adding the rotation block to the channel pins, it gets asked twice a week
bled a bit afterwards. normal?
a pinprick of blood is normal. press with a dry swab, do not rub
bruising happens too, and rubbing is what makes it worse
ok. that was far less dramatic than i had built it up to be
it always is. the first one is the hard one
