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?

    "None of them produce anything that looks wrong" is the unifying point. Every one is a silent failure, which is exactly the class tooling is good at preventing and vigilance is bad at.

    Good thing to point new members at. Short, and the highest consequence material in the beginner category.

      Reading the wrong syringe scale, but that folds into #3.
