Highlights from this day
the vacuum will pull it in. let it. fighting it is how you get a face full of aerosol

does benzyl alcohol matter if im finishing the vial in one go
too dilute imo
20mg in 2ml is 10mg/ml. 1mg is 10 units, 2mg is 20 units, easy
anyone worked out a recon volume that puts 1.7mg on a round unit mark
pick the volume so your dose is a whole number of units. thats the entire trick, take that with a pinch of salt
i write the mg/ml on the vial with a sharpie the moment i reconstitute it, still working it out
gross powder mass is not net peptide. water and counterion are in that number
weigh it first
weighing the vial before you reconstitute is the only way to catch an underfill
check your maths
unrelated but i use bac water even for a single-use vial because it stings less, which is not the reason it exists
aim the diluent at the glass wall, not at the powder. it goes in gentler
is it normal for the cake to look slightly collapsed on one side
i swirl for about thirty seconds and then leave it. never had one fail to dissolve
30mg in 3ml is 10mg/ml, so 5mg is 50 units. half the barrel, feels like a lot but its right
took me a year to stop over-diluting. the measurement error at 4 units is worse than the convenience
do you draw up with the same pin you inject with

i have never once regretted using a rounder number and a slightly bigger volume
if you cannot read the mark confidently, your volume is too small. redo it at a lower concentration
round numbers
one unit is 0.01ml
update from 15 months ago: switched to a single concentration and have not miscalculated since
if i add 1ml to a 2mg vial what concentration am i actually at
✅11
thats 5mg/ml
yep 10 units
follow up a slightly collapsed cake is cosmetic. a puddle in the bottom is not
right so does it matter if i inject the bac water straight at the powder
read it at eye level
