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.

GHK-Cu at a glance

Quick reference for the protocol-builder. GHK-Cu is naturally present in human plasma and declines with age — most self-protocols frame supplementation as restoring younger levels.

ClassCopper-bound tripeptide (Gly-His-Lys + Cu²⁺)
Brand namesNone as injectable; topical formulations exist (CopperPeptideGHK and others)
Plasma half-lifeShort (hours); local tissue effects extend longer
Typical cadenceEvery other day, or 3× weekly
Typical dose range1–2 mg per injection; some longevity protocols go 2 mg every other day
Common reconstitution50 mg vial + 5 mL bacteriostatic water → 10 mg/mL → 0.10 mL = 1 mg dose
Insulin syringeU-100 most common (10 units = 0.10 mL = 1 mg at 10 mg/mL)
Common stack pairingsGenerally run alone or layered onto longevity stacks (Epitalon, MOTS-C); rarely combined in a single vial
Cycle length8–12 weeks on, 4 weeks off is the most cited self-protocol pattern

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 (copper tripeptide) ships as a preset at common 50 mg and 100 mg vial strengths. Set the BAC water volume, target your dose in mg, and the app outputs the unit count. Be aware that GHK-Cu solutions are blue-green — that's the copper, not contamination.

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.
