The dose you planned, the dose you drew, and the dose you delivered
The dose you planned, the dose you drew, and the dose you delivered

Three different quantities hide behind the word "dose", and a log that only records one of them will eventually mislead you.
The planned dose is what the schedule says. It is a number on paper and it is the one people write down, because it is known in advance and requires no attention at the moment of injection.
The drawn dose is what ended up in the barrel. Usually it matches the plan. Sometimes it does not, because the mark you aimed at was between graduations, or a bubble made you push some back, or you simply overshot and decided it was close enough. The drawn dose is knowable, and it is the number you can actually read off the syringe before the needle goes in.
The delivered dose is what entered you. It differs from the drawn dose when the plunger was not fully depressed, when the needle came out early, when there was leakage at the site, or when the injection was interrupted. This is the least knowable of the three and the one most worth flagging when it is in doubt.
A useful log records the plan once, per schedule, and then records the drawn amount per injection, with a flag when delivery was uncertain. You do not need three columns on every row. You need one column for what you drew and a way to mark the occasional row where delivery was not clean.
Why it matters: if you are tracking anything at all against dose, whether that is tolerability, weight, or simple adherence, the correlation you are looking for is against the delivered amount. Attributing an outcome to the planned dose when three of the last ten injections were partial is how people conclude that a dose does not work when in fact it was never fully taken.
The honest entry for an uncertain delivery is not a guess at a percentage. It is a note that says what happened: "plunger caught, pushed remainder after a pause" or "wet at the site afterwards, unknown loss". Those descriptions are reconstructable later; a made-up 80 percent is not.
Somewhere structured helps here, because a free text note attached to a numeric row is easy to lose in a spreadsheet and easy to keep in a Peptide Tracker & Calculator built for dose entries. The point is not the tool. The point is that "what I meant to take" and "what I took" are different columns, and only one of them is evidence.
