Dosing arithmetic, reconstitution maths, and how people use the tracker.
The math is trivial: total mass / mass per draw = number of draws. 10mg vial, 500mcg per draw, 20 draws. Where it stops being useful: that assumes the limiting factor is running o…
Collected from the threads in this category over the last few months. 1. Treating syringe units as a mass. They're a volume marking. Meaningless without a concentration. 2. mg/mcg…
Written out because the errors cluster in predictable places. Mass: 1mg = 1000mcg. 1mcg = 0.001mg. Volume: 1ml = 1000 microliters. U-100 syringe, 100 units = 1ml so 1 unit = 0.01m…
Extremely common question, always asked like there's a correct number. There isn't, it's a choice with trade offs. More water: more dilute, so a given amount takes up more volume …
This is the calculation everything else depends on so here it is in full, because the failure mode is a 10x error not a small one. Three numbers and you need all three: the mass i…
