Four things a peptide dose log should record

A dose log stays useful over months when it records four things rather than one.

Reconstitution: a vial’s labeled strength is not a dose. Add the diluent, divide the total mass by the volume of water, and you have mg per mL, and from there a dose in mL and in insulin units.

Titration: the useful record is the step history, not just today’s number.

Site rotation and post-puncture expiry are both worth recording next to that ratio.

I keep the dose log, calculators and half-life curves in Peptide Tracker & Calculator, which stores everything on the device.

Nothing here is medical advice; dosing decisions belong with your prescriber.
