Highlights from this day

luerlok — abdomen two inches out from the navel, avoiding anything that has been injected in the last month 12:52
luerlok — a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call 13:21
VialBot — New independent result logged — SGN, lot H-2814, purity 98.6% (PeptideMeter). 13:27
void_volume — thigh or abdomen, does absorption actually differ 13:34
impersonator_ip — a proper sharps bin costs almost nothing and pharmacies will take it back, for what its worth 15:19

does injecting a cold vial hurt more or am i imagining it

i mark the rotation in a notes app because the marks fade and i lost track twice, thats one data point

try the thigh

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

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

30G in 8mm or 12.7mm for abdomen

if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle, n of 1 obviously

welts at the site are usually a mild local reaction and rotation sorts it

push slowly. fast is what causes the ache afterwards

abdomen two inches out from the navel, avoiding anything that has been injected in the last month

wk1 L abdo upper   wk5 L thigh outer
wk2 R abdo upper   wk6 R thigh outer
wk3 L abdo lower   wk7 L arm back
wk4 R abdo lower   wk8 R arm back

a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it

a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call

absorption differences between subcutaneous sites are small for a weekly compound, your mileage will differ

how slowly should you actually push

cold from the fridge genuinely stings more. i let it sit out for ten minutes

thigh or abdomen, does absorption actually differ

wk1 L abdo upper   wk5 L thigh outer
wk2 R abdo upper   wk6 R thigh outer
wk3 L abdo lower   wk7 L arm back
wk4 R abdo lower   wk8 R arm back

nobody here should be telling you where to inject. we can tell you what we do

bleeding a little means you nicked a small vessel. it is not a technique failure

let it dry

a proper sharps bin costs almost nothing and pharmacies will take it back, for what its worth

how do you avoid hitting the same spot twice when the marks fade

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