    Your dose record. Modelled, not measured.

    Record what you actually used, review and correct your history, and see a modelled half-life curve built only from those records. Nothing is preloaded, and the tracker never suggests a dose.

    Frequently asked questions

    Is the New-U peptide tracker free?

    Yes - calculator, schedules, and dose log are free with no signup. Charts appear only after you log real doses. Without an account, records are kept against an anonymous device ID on our server, with a copy in this browser for offline use; sign in to sync across devices and turn on Email / SMS / iCal reminders.

    Does it support semaglutide and tirzepatide titration?

    The schedule builder can show the published prescribing-information ladders for the approved medicines semaglutide (Wegovy), tirzepatide (Mounjaro) and liraglutide (Saxenda) as an educational reference. Retatrutide is investigational and not FDA-approved, so it has no preset ladder; you enter your own schedule. A reference ladder is not a dosing recommendation, and the tracker never raises a dose for you.

    How do reminders work?

    Pick any combination of Email, SMS, and iCal per schedule. Email / SMS fire from a cron sweep at your configured offset; the iCal feed plugs into Apple or Google Calendar so your phone's native notifications handle the rest.

    What does the half-life decay chart show?

    Only after you log real doses. It is a single-compartment exponential-decay overlay of modelled amount remaining for compounds you have already logged - never a preloaded demo. Half-lives come from regulatory labels where available and peer-reviewed studies. Educational only - not medical advice .

    Does it handle injection-site rotation?

    Yes - a 12-zone body map colour-codes sites by recency: red < 7 days, amber < 30 days, green clear. It records where you logged; it is not injection guidance.

    Which peptides are in the catalog?

    GLP-1s (semaglutide, tirzepatide, retatrutide, liraglutide), healing peptides (BPC-157, TB-500), GH secretagogues (ipamorelin, CJC-1295 ±DAC, sermorelin, tesamorelin), cosmetic (GHK-Cu), metabolic (MOTS-c, AOD-9604), longevity (epitalon). Citations at /api/tracker/catalog .

    Can I install the tracker as an app on my phone?

    iPhone: Safari → Share → Add to Home Screen. Android: tap the Install prompt in the Chrome address bar. Install guide.

    Is this medical advice?

    No. The tracker records what you enter. Reference ladders appear only for approved medicines and are not dosing recommendations. Consult a qualified clinician.
