Built for weekly GLP-1 injections and multi-peptide stacks. Track semaglutide, tirzepatide, and other peptides from a ready library, or add your own. Log dose amount, date, and injection site. Use the dose calculator for vial strength, bacteriostatic water, and insulin-syringe units so draws stay clear and consistent.

Spreadsheets bury units math. Peptide Tracker focuses on what shot-day tracking needs: dose log, units calculator, injection sites, calendar history, and progress charts, without turning logging into another full-time job.
