Highlights from this day
- pin29g — while im here 31G 8mm for everything. i tried the 12.7mm once and never went back 19:33
- adelaide_assay — welts at the site are usually a mild local reaction and rotation sorts it 19:45
- pinch_not_stretch — do you change the pin between drawing up and injecting 20:13
- VialBot — New independent result logged — HJ, lot KP-0925, purity 98.1% (Janoshik). 21:00
- tga_notice — coming back to this a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it 22:14
drawing up with the same pin you inject with is fine, it just dulls the tip slightly
i keep the sharps bin next to the fridge so the whole thing happens in one place

update from 4 months ago: switched to a fixed rotation and the site reactions stopped
cold from the fridge genuinely stings more. i let it sit out for ten minutes
i changed nothing except letting the swab dry and the stinging stopped completely
fresh pin
do you use the insulin syringe for both drawing and injecting
push slowly. fast is what causes the ache afterwards
*Medutest not the other one
how far from the navel is actually far enough
follow up does injecting a cold vial hurt more or am i imagining it
pinch
90 degrees or 45
does the injection site matter for how quickly it hits
warm it first
let the alcohol dry. that is ninety percent of "my injections sting"
thats normal
while im here 31G 8mm for everything. i tried the 12.7mm once and never went back

let it dry
ok so a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
bleeding a little means you nicked a small vessel. it is not a technique failure
welts at the site are usually a mild local reaction and rotation sorts it

anyone got a rotation map they would share
*Janoshik not the other one
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 years and almost no bruising
do you count to five before withdrawing
the difference between 29G and 31G is real but small. the difference between wet and dry alcohol is not small
let the alcohol dry. that is ninety percent of "my injections sting"

*that should say weekly
45 degrees
do you change the pin between drawing up and injecting

how do you avoid hitting the same spot twice when the marks fade
abdomen two inches out from the navel, avoiding anything that has been injected in the last month
absorption differences between subcutaneous sites are small for a weekly compound
do you aspirate, or is that only an intramuscular thing
❤️11😂3
while im here never recap a used pin. that is how people stick themselves
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
a proper sharps bin costs almost nothing and pharmacies will take it back
New independent result logged — HJ, lot KP-0925, purity 98.1% (Janoshik).

warming the vial in your hand for a minute is the cheapest comfort improvement there is
nobody here should be telling you where to inject. we can tell you what we do
sorry to jump in do you pinch or stretch

thigh or abdomen, does absorption actually differ
thats a reaction
i bled a bit, is that a needle depth thing
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
90 degrees works fine if you have the tissue for it. 45 if you do not
bleeding a little means you nicked a small vessel. it is not a technique failure
coming back to this a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
