- c18_column — do you change the pin between drawing up and injecting 15:01
for the archive absorption differences between subcutaneous sites are small for a weekly compound

push slow
update from 19 months ago: switched to a fixed rotation and the site reactions stopped
sharps bin
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
i have eight sites and an eight week rotation. it is written on the fridge
not a problem

how far from the navel is actually far enough
bleeding a little means you nicked a small vessel. it is not a technique failure

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

quick one thigh or abdomen, does absorption actually differ
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

abdomen two inches out from the navel, avoiding anything that has been injected in the last month, someone check my working

45 degrees

small bubble is fine
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
welts at the site are usually a mild local reaction and rotation sorts it

fresh pin
warming the vial in your hand for a minute is the cheapest comfort improvement there is
warm it first
for the archive the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
i bled a bit, is that a needle depth thing

do you pinch or stretch
[edited]how do you avoid hitting the same spot twice when the marks fade
cold from the fridge genuinely stings more. i let it sit out for ten minutes
📈7🧪13
thats normal

i mark the rotation in a notes app because the marks fade and i lost track twice
push slowly. fast is what causes the ache afterwards
31G 8mm for everything. i tried the 12.7mm once and never went back
do you change the pin between drawing up and injecting

never recap a used pin. that is how people stick themselves
i keep the sharps bin next to the fridge so the whole thing happens in one place
[edited]how many sites are in your rotation
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
a proper sharps bin costs almost nothing and pharmacies will take it back, i think
mark it down
rotate
