Highlights from this day
  • bea_reconstitutes — i keep the sharps bin next to the fridge so the whole thing happens in one place, i think 20:00
  • otto_swirls — the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small 20:13
  • drawup_dee — how far from the navel is actually far enough 22:04
  • otto_swirls — cold from the fridge genuinely stings more. i let it sit out for ten minutes 22:32
  • mcg_not_mg — thigh or abdomen, does absorption actually differ 22:50

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle

OS

a proper sharps bin costs almost nothing and pharmacies will take it back

does the injection site matter for how quickly it hits

absorption differences between subcutaneous sites are small for a weekly compound, ask me again in a month

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising

BB

the needle went in fine but it stung going in, alcohol or the compound

MN

90 degrees works fine if you have the tissue for it. 45 if you do not

OS

i changed nothing except letting the swab dry and the stinging stopped completely

thats normal

OS

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

sorry to jump in welts at the site are usually a mild local reaction and rotation sorts it

90 degrees or 45

i bled a bit, is that a needle depth thing

bleeding a little means you nicked a small vessel. it is not a technique failure, your mileage will differ
