Read more →How long does semaglutide stay in your system?
Semaglutide's half-life is about a week, so it takes roughly five weeks to clear. The label numbers for Ozempic, Wegovy, tirzepatide and liraglutide, and Peppy's active-level curve.
Read more →Tracking GLP-1 side effects and food noise against your dose days
What food noise is, how common the GLP-1 side effects are per the labels, and why logging them by dose day matters. Peppy's daily check-in and side-effect heat-map.
Read more →Peptide tracking spreadsheet vs a pill reminder vs Peppy: an honest comparison
What a spreadsheet, a generic pill reminder and Peppy each handle for peptides and GLP-1s: reconstitution math, rotation, cycles, inventory, half-life, reminders and export.
Read more →Peptide cycle tracker: what "5 on, 2 off" means as a schedule, and how to keep it straight
How on/off peptide cycles work as scheduling, why the off days are where tracking fails, and how Peppy's cycle presets auto-skip off days and show them on the calendar.
Read more →Peptide stack tracker: run BPC-157, TB-500 and CJC/Ipa as separate protocols with one Today list

Read more →Compounded semaglutide and tirzepatide units: how the mg on your prescription becomes units on the syringe
Units = dose in mg ÷ the vial's mg/mL × 100. Worked examples for compounded semaglutide and tirzepatide, why the label's mg/mL matters, and a calculator.
