Highlights from this day
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small, thats one data point
thigh or abdomen, does absorption actually differ
thats normal
💀1😂15📈18
31G 8mm for everything. i tried the 12.7mm once and never went back
while im here i keep the sharps bin next to the fridge so the whole thing happens in one place

pinch
coming back after 21 months, has the pinned technique guide changed
[edited]bleeding a little means you nicked a small vessel. it is not a technique failure, i could be wrong

the needle went in fine but it stung going in, alcohol or the compound
for the archive i changed nothing except letting the swab dry and the stinging stopped completely
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
warm it first
[edited]i bled a bit, is that a needle depth thing

small bubble is fine
unrelated but i have eight sites and an eight week rotation. it is written on the fridge
push slow
for the archive is there any reason to warm the vial in your hand first
ok so abdomen two inches out from the navel, avoiding anything that has been injected in the last month
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
✅1⚠️1💀15
slightly off topic but a proper sharps bin costs almost nothing and pharmacies will take it back, we shall see
i mark the rotation in a notes app because the marks fade and i lost track twice
31G 8mm
i inject the back of my own arm and it is awkward but doable with a mirror
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

absorption differences between subcutaneous sites are small for a weekly compound
⚠️3
not a problem
cold from the fridge genuinely stings more. i let it sit out for ten minutes, from memory
how far from the navel is actually far enough

do not reuse pins. it is not about sterility so much as the tip being blunt after one pass
*Medutest not the other one
90 degrees works fine if you have the tissue for it. 45 if you do not

never recap a used pin. that is how people stick themselves
[edited]try the thigh
mark it down

is 31G noticeably better than 29G or is it marginal
🧊1👀5
warming the vial in your hand for a minute is the cheapest comfort improvement there is
technique probably
let it dry
unrelated but do you change the pin between drawing up and injecting
Batch lookup B-0114: 2 independent reports on file, earliest 2025-08-24.
welts at the site are usually a mild local reaction and rotation sorts it
🎉15👀8
does injecting a cold vial hurt more or am i imagining it
45 degrees
thats a reaction
let the alcohol dry. that is ninety percent of "my injections sting", ymmv

do not aspirate for a subcutaneous injection, there is nothing to aspirate for
i keep the sharps bin next to the fridge so the whole thing happens in one place
