Every observational record is only as good as its weakest entry. For years the weakest entry in home peptide use was the dose itself: powder reconstituted in a kitchen, a volume drawn into an insulin syringe, a number that lived in someone’s head.
A record needs a unit
“A few ticks on the syringe” cannot be compared with anything, including the same owner a month later. A cartridge with a fixed concentration and a pen that dials in units gives every entry the same unit. Nine units today is nine units in March. That is what makes a before-and-after worth reading.
What Fieldnotes does with it
A journal entry can carry a dose line: formula, units, time. Fieldnotes records it; it never recommends it. Canitide publishes the weight-band cards for its formulas and says plainly that the bands come from published mg/kg ranges, not from canine trials. Keeping those two roles apart is the point.
What it still doesn’t prove
A cleaner dose record does not turn an owner’s journal into a controlled study. It removes one source of noise. The others, self-selection, missing days, different dogs, stay visible in every reviewed record on this site.
The pen itself, and why Canitide built it instead of selling vials, is on canitide.com/pen.
