The peptide and GLP-1 tracker that gets the units right.
Log HCG in IU, not mg. Reconstitute a vial once and every entry shows your draw in mL and syringe units. Watch the supply count down. Keep labs, side effects, and photos next to the record. Nothing leaves your phone.
Free for one protocol, with every logging feature. No account, no cloud.
Built for how peptides and GLP-1s are actually used.
Most trackers treat them like a generic medication. Peptometer knows a vial from a pen, IU from mg, and a draw from a dose.
Correct units, per compound
102 compounds ship ready to log, each with only the units that are valid for it. IU stays IU, pens log the mg on the label, sprays count sprays, orals count tablets.
Reconstitute once
Vial size and water in, concentration and draw out, in mL and syringe units on a live syringe drawing. The result saves into your protocol and shows on every future entry.
Logging that fits real life
Protocols and stacks, titration phases and on-and-off cycles you enter yourself, reminders that open the log sheet, injection sites, notes, backdating, and edits.
Supply that counts down
Vials, pens, sprays, and packs, with the doses left, the date they run out, and a warning before it.
Your own record
Body metrics, side effects, lab results next to the range your lab printed, progress photos, and insights about your own rhythm, all computed on the phone.
A library that shows its sources
What published research found, what a US label or trial used, live trial and paper listings, and what communities say, kept apart and labelled unverified.

Peptometer Plus Adds
- Estimated levelsA rough curve of how much may still be in your body, drawn from your own entries and how long the compound is known to last (its half-life, from human studies). Always labelled an estimate.
- Your record, in chartsWhen you usually log, how many of your scheduled days had an entry, entries per week, weight, and side effects, all computed on the phone.
- Plan the whole courseLater amount changes (phases) and on-and-off cycles you enter once; Today, reminders, the calculator, and the run-out date follow them.
- Never run drySpare vials and pens counted, and a morning warning before your supply runs out.
- Today on your Home and Lock ScreenA widget with what is logged, the next entry on your schedule, and doses left, refreshed from your own records whenever you log.
- Weight from Apple HealthWeight and body fat imported from Apple Health into Metrics, so a smart scale lands next to your entries. Import only; Peptometer writes nothing to Health.
- A one-page summary for your providerIn front of the PDF export: your protocols as entered, days logged against your schedule, side effects, latest labs, and the change in your measurements.
- Unlimited protocols and stacksOne active protocol is free forever; Plus runs as many as you need at once.
Prices in US dollars; the app shows your local price. Purchases are handled by Apple and nobody else, including us, sees them. If Plus ends, nothing you saved is removed or hidden.
A library that shows its sources.
Every compound has an entry: what it is, how it is thought to work, what published research found, what a US label or a trial used with the source one tap away, regulatory status, and live listings from ClinicalTrials.gov and PubMed. What communities say is kept apart from the studies and labelled unverified.
Regulatory status as of September 2026. Community notes gathered by web search on September 10 to 28, 2026, labelled unverified.
In the studies
Published research with trial names and outcomes, label warnings, and the amounts a label or a trial used, each with its source and its setting.
Talked about in communities
What people say they notice, what bothers them, the habits and mix-ups they describe, gathered by web search, dated, and never mistaken for evidence.
