GHK-Cu tracker
for iPhone.
GHK-Cu is the cosmetic / longevity peptide that doesn't fit the usual mold — a tiny tripeptide bound to a copper ion, blue-green in solution, used for skin elasticity, hair density, and broader anti-aging hypotheses. Cadence is light (every other day or thrice weekly) and the math is unfussy. What it really needs is a clean adherence log over a long cycle. Peptide Protocol gives it one.

| Class | Copper tripeptide (Gly-His-Lys + Cu²⁺); dermatology / research |
|---|---|
| Brand names / aliases | Copper tripeptide-1, GHK-copper |
| Regulatory status | Research-only as an injectable — no FDA-approved human label |
| Evidence level | FDA regulatory notice / literature |
| Plasma half-life | No FDA-approved label half-life. |
| Approved presentation | No FDA-approved injectable presentation. Topical cosmetic formulations are sold but are out of scope for the injection-tracking workflow. |
| Dose initiation | No verified label dosing. Self-protocols typically run 1–2 mg per dose, every other day or 3× weekly. |
| Side-effect notes | Limited human safety data for injectable use. The reconstituted solution is naturally blue-green from the copper chelate — a real chemistry signature, not contamination. |
| Key caveat | Injectable GHK-Cu is unapproved by the FDA. Do not confuse with copper-free GHK (Gly-His-Lys), which is a different molecule without the copper signature. |

Built around GHK-Cu protocols
Three things light-cadence cosmetic protocols actually need.
Every-other-day scheduling
Default cadence options include daily, every-other-day, and 3× weekly. Pick yours and the app schedules the next dose without you having to count days. Reminders only fire on dose days.
Long-cycle adherence view
Cosmetic outcomes show up over 8–12 weeks of consistent dosing. The Insights tab tracks cycle adherence as a single number plus a heatmap, so you can see at a glance whether the protocol actually ran or got patchy in week six.
Skin / hair check-in fields
Daily check-ins include free-text plus a customizable rating for skin and hair quality. The weekly report aggregates them so the cosmetic outcome you're after gets reflected in the same view as the dose log.

GHK-Cu tracking — common questions
Does Peptide Protocol have a GHK-Cu preset?
Yes — GHK-Cu is supported in the calculator. Because injectable GHK-Cu has no FDA-approved human label, the app does not ship a default dose; you enter your vial mass, BAC water volume, and target dose, and the calculator returns the unit count. Note that the reconstituted solution is naturally blue-green from the copper chelate — that's real chemistry, not contamination, and it's a useful sanity check that you have actual GHK-Cu rather than copper-free GHK.
What cadence does the app use for GHK-Cu?
Most self-protocols run GHK-Cu every other day or 3 times per week — a quieter cadence than the daily peptides. The app supports either pattern in the protocol-builder, plus a custom interval if you've worked out something different with your provider.
Can the app track topical / oral / SC routes for GHK-Cu?
GHK-Cu has multiple delivery routes (subcutaneous, topical creams, scalp serums). The app's first-class workflow is for the SC injection route — calculator, rotation, schedule. If you also use topical, you can track adherence as a daily check-in tag, but the main protocol surface is built around the injection cadence.
