genuine question about concentration that I am slightly embarrassed to ask
genuine question about concentration that I am slightly embarrassed to ask. If this has been answered properly somewhere, link me and I will delete. The failure modes I have actually seen posted here, in order of frequency. One: reconstituting at a different volume than intended and not writing it down, so the next…
the powder cake sits at the bottom, the volume you add is the volume that counts
Disagree with the "more water is safer" framing. It is not safer, it is just a different number to divide by.
dead space in the needle hub is real and it is small
Right — the volume you add is the only variable you control here, and the cake does not change it meaningfully.

Disagreeing with this line only: adding more water is not a safety margin, it is a different divisor.
Shook the first vial because nobody told me not to. It was fine, but I have swirled every one since.
Did the maths give you a whole number of units, or a fraction?
Pushback on the syringe advice: a U-100 barrel reads units of volume. Calling them "doses" is how the confusion starts.
