Highlights from this day
- meniscus_mel — is there any reason to warm the vial in your hand first 17:39
- luerlok — bleeding a little means you nicked a small vessel. it is not a technique failure 18:15
- peak_split — i mark the rotation in a notes app because the marks fade and i lost track twice 19:10
- rory_reships — nobody here should be telling you where to inject. we can tell you what we do drawing up with the same pin you inject with is fine, it just dulls the tip slightly 20:43
- monoisotopic — never recap a used pin. that is how people stick themselves 22:07

genuine question do you use the insulin syringe for both drawing and injecting
how many sites are in your rotation
technique probably
i keep the sharps bin next to the fridge so the whole thing happens in one place, still working it out
😂9🎉1
how slowly should you actually push

push slow
i inject the back of my own arm and it is awkward but doable with a mirror

i keep getting a small welt at the site, technique or reaction
cold from the fridge genuinely stings more. i let it sit out for ten minutes

45 degrees
31G 8mm for everything. i tried the 12.7mm once and never went back
thats a reaction
not a problem
how far from the navel is actually far enough
*Medutest not the other one
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

wk3 L abdo lower wk7 L arm back
wk4 R abdo lower wk8 R arm backif you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
thigh or abdomen, does absorption actually differ

small bubble is fine
do not aspirate for a subcutaneous injection, there is nothing to aspirate for, thats just me
does the injection site matter for how quickly it hits

is 31G noticeably better than 29G or is it marginal
rotate
for the archive i have eight sites and an eight week rotation. it is written on the fridge
90 degrees works fine if you have the tissue for it. 45 if you do not, i have it written down somewhere
sharps bin
dont recap
update from 10 months ago: switched to a fixed rotation and the site reactions stopped
Purity check: no report on file for lot G-0641. Nothing logged either way.
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
31G 8mm for everything. i tried the 12.7mm once and never went back
warm it first

a proper sharps bin costs almost nothing and pharmacies will take it back
does injecting a cold vial hurt more or am i imagining it
is bruising more about the needle or the aftercare
nobody here should be telling you where to inject. we can tell you what we do
drawing up with the same pin you inject with is fine, it just dulls the tip slightly

mark it down
welts at the site are usually a mild local reaction and rotation sorts it
i changed nothing except letting the swab dry and the stinging stopped completely
i bled a bit, is that a needle depth thing

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