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

Highlights from this day
- electrolyte_eli — unrelated but 31G 8mm for everything. i tried the 12.7mm once and never went back, n of 1 obviously 18:55
- u100_pat — i inject the back of my own arm and it is awkward but doable with a mirror 19:37
- sharps_comedy — nobody here should be telling you where to inject. we can tell you what we do 19:40
- marrow.mod — bleeding a little means you nicked a small vessel. it is not a technique failure 21:02

is bruising more about the needle or the aftercare
how far from the navel is actually far enough
warm it first
31G 8mm
mark it down
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
absorption differences between subcutaneous sites are small for a weekly compound
warming the vial in your hand for a minute is the cheapest comfort improvement there is
let it dry
push slowly. fast is what causes the ache afterwards

cold from the fridge genuinely stings more. i let it sit out for ten minutes
i have eight sites and an eight week rotation. it is written on the fridge

fresh pin
for the archive i bled a bit, is that a needle depth thing
i mark the rotation in a notes app because the marks fade and i lost track twice, happy to be corrected
for the archive abdomen two inches out from the navel, avoiding anything that has been injected in the last month
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
push slow
pinch
Inter-lab diff for lot F-1330: 98.1% vs 97.4%. Within expected range.
i changed nothing except letting the swab dry and the stinging stopped completely, someone check my working
i keep getting a small welt at the site, technique or reaction
try the thigh

does the injection site matter for how quickly it hits
for the archive never recap a used pin. that is how people stick themselves
while im here update from 7 months ago: switched to a fixed rotation and the site reactions stopped
i keep the sharps bin next to the fridge so the whole thing happens in one place
does injecting a cold vial hurt more or am i imagining it
do you count to five before withdrawing
thats normal
not a problem
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
a proper sharps bin costs almost nothing and pharmacies will take it back
sharps bin
how many sites are in your rotation
