About & disclaimer

About

goodtides Companion is a personal peptide tracking tool — a calculator, a logbook, a schedule, all in your pocket. Local-first; optional cloud sync.

What it is, and isn't

What it is: a tracker. It records what you input — your protocols, doses, injections, vials, schedules — and does the arithmetic of converting vial mg + water mL into syringe units. Catalog defaults shown alongside peptides are commonly cited research dosages, included as a reference.

What it isn't: a medical service. goodtides does not provide medical care, evaluate your condition, or advise on individual dosing. Peptides referenced are research chemicals, not FDA-approved drugs.

Your decisions, your responsibility

Decisions about whether and how you use these products are your own. Consult a licensed medical provider before starting, adjusting, or combining any protocol — including for any dosing or protocol guidance you follow from this app.

Your data & privacy

Your tracking data (protocols, doses, vials, weights, and any bloodwork you add) is stored on your device, and synced to your goodtides account only if you sign in — so it's available across your devices. It is never used for advertising or sold. Read our App Privacy Policy and Terms.
