- lean_mass_lex — the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small 10:51
- lean_mass_lex — do you count to five before withdrawing 12:28
- warsaw_vial — for the archive do not reuse pins. it is not about sterility so much as the tip being blunt after one pass pinch, 45 degrees, count to five, withdraw slowly. two… 12:30
- nettle_notes — is 31G noticeably better than 29G or is it marginal 14:55
warming the vial in your hand for a minute is the cheapest comfort improvement there is
push slowly. fast is what causes the ache afterwards
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
do not aspirate for a subcutaneous injection, there is nothing to aspirate for

[edited]never recap a used pin. that is how people stick themselves
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
fresh pin
is a small air bubble in the barrel a problem subcutaneously
a proper sharps bin costs almost nothing and pharmacies will take it back
coming back after 5 months, has the pinned technique guide changed
do you count to five before withdrawing

pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
i keep getting a small welt at the site, technique or reaction
90 degrees or 45
[edited]thigh or abdomen, does absorption actually differ
30G in 8mm or 12.7mm for abdomen
follow up anyone got a rotation map they would share
how do you avoid hitting the same spot twice when the marks fade
update from 22 months ago: switched to a fixed rotation and the site reactions stopped
how many sites are in your rotation
anyone inject in the back of the arm on their own successfully
is bruising more about the needle or the aftercare
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising, i think
is 31G noticeably better than 29G or is it marginal
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
31G 8mm
i keep the sharps bin next to the fridge so the whole thing happens in one place
coming back to this i mark the rotation in a notes app because the marks fade and i lost track twice
