Highlights from this day
- septum_sal — how far from the navel is actually far enough 19:02
- VialBot — Purity check: no report on file for lot A-2418. Nothing logged either way. 19:03
- septum_sal — does the injection site matter for how quickly it hits 19:28
- chlorhex — is bruising more about the needle or the aftercare i changed nothing except letting the swab dry and the stinging stopped completely 20:18
- septum_sal — coming back to this a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it 20:40
rotate
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
31G 8mm for everything. i tried the 12.7mm once and never went back
small bubble is fine
abdomen two inches out from the navel, avoiding anything that has been injected in the last month
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
fresh pin

while im here anyone inject in the back of the arm on their own successfully
is 31G noticeably better than 29G or is it marginal
does the injection site matter for how quickly it hits

a proper sharps bin costs almost nothing and pharmacies will take it back
cold from the fridge genuinely stings more. i let it sit out for ten minutes
push slow

is a small air bubble in the barrel a problem subcutaneously
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
thats a reaction
coming back to this a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
welts at the site are usually a mild local reaction and rotation sorts it
absorption differences between subcutaneous sites are small for a weekly compound
is there any reason to warm the vial in your hand first
