Frequently asked questions

Is the New-U peptide tracker free?

Yes - calculator, protocols, and PK chart are free with no signup. Data lives in your browser; sign in to sync across devices and turn on Email / SMS / iCal reminders.

Does it support semaglutide and tirzepatide titration?

Yes. Built-in ladders: semaglutide 0.25 → 2.4 mg weekly, tirzepatide 2.5 → 15 mg weekly, retatrutide 2 → 12 mg weekly, liraglutide 0.6 → 3.0 mg daily. The ladder advances on the configured step weeks.

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 PK concentration chart show?

A single-compartment exponential-decay overlay across every logged + projected dose. Half-lives come from FDA labels and peer-reviewed PK 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. Auto-suggests the next site to avoid repeat injections.

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. Products are for research use only and not for human consumption. The ladders reproduce published FDA-label schedules with citations - they are not dosing recommendations. Consult a qualified clinician.

Pair it with a vial

Sign in after buying a research compound and the tracker auto-suggests a protocol pre-filled with your vial size + FDA-label ladder.

For research use only. Not for human consumption. The pharmacokinetic chart uses a single-compartment exponential-decay model with half-life values drawn from FDA labels and peer-reviewed studies. It is an educational visualization, not a clinical PK calibration, and is not medical advice.
