the 5 peptide dosing math mistakes that cause most of the confusion here
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 slips. Factor of 1000, and it reads plausibly either way. 3. Assuming U-100. Usually true. Silently wrong when it isn't. 4. Copying someone else's unit count. Their number encoded their reconstitution, not yours. 5. False precision. Calculating to a resolution the syringe can't deliver, then treating small differences as meaningful.
What unites all five: none of them produce anything that looks wrong. The solution is clear, the syringe reads normally, the math is internally consistent. There's no feedback.
That's the whole argument for using a tool that holds all the variables at once, and for writing the concentration on the vial rather than the mass. Did I miss one?
