Peptide Tracker is a private logbook and arithmetic dosing calculator for peptides and GLP-1 therapies used under the direction of a licensed healthcare provider. No account. No sign-in. No analytics. Everything you enter stays on your device. RECONSTITUTION CALCULATOR Enter your vial strength, the volume of bacteriostatic water you added, your syringe type, and the dose your provider directed. You get the resulting concentration in mg/mL, the volume to draw, the mark to fill to on the syringe, and how many doses the vial holds. It is arithmetic on the numbers you enter — nothing more. It does not recommend a dose. DOSE LOG Record what you took and when: substance, amount, unit (mg, mcg, IU or mL), route, and any notes. Your recent doses stay one tap away. VIALS Track each vial's remaining amount, concentration and expiry date. Logging a dose from a vial decrements it automatically, so the amount you see is the amount that is actually left. Vials are flagged in the app as they approach expiry, run empty, or expire. SCHEDULE Keep your planned cadence in one place — daily, every N days, specific days of the week, or on/off cycles — and get a reminder when a dose is due. SEARCHABLE CATALOG Common GLP-1 and provider-directed peptides, searchable by name or by the other names you may know them by. Add your own entries at any time. Research peptides are hidden by default and can be turned on in Settings. PRIVATE BY DESIGN - No account and no sign-in. - No analytics and no tracking. - Works fully offline. - Export everything you have entered as CSV or JSON whenever you want. IMPORTANT Peptide Tracker is a record-keeping and calculation tool. It is not medical advice and does not diagnose, treat, cure, or recommend any dose or substance. It does not sell, source, or link to any product. Always follow the instructions of your licensed healthcare provider, and use only the substances and protocols your provider directs.
