GHK-Cu Tracker for iPhone

OptiPin is a private GHK-Cu tracker that turns a copper-peptide protocol into a clean, reviewable record – whether you run it injectable or topical. Log each dose, keep count of the doses left in each vial, rotate injection sites, note side effects like temporary flushing, and track skin and hair progress over time – with a warning before a vial runs out. Everything stays on your device; no account, no cloud upload.

Status – research compound

Cosmetic-legal topically; injectable not approved. As "Copper Tripeptide-1," GHK-Cu is an established cosmetic ingredient in topical skincare. As an injectable drug it is not FDA-approved and is sold as a "research chemical" – an unregulated channel with no verified purity, sterility or dose accuracy. OptiPin is a tracking tool and does not endorse or facilitate obtaining injectable research-grade material.

Why track GHK-Cu at all

GHK-Cu is the copper tripeptide-1 – a naturally occurring copper-binding peptide studied for skin, hair, wound healing and anti-aging, with genuinely strong topical evidence and much thinner injectable evidence. Because it is run two ways – subcutaneous injection (reconstituted from larger mg-scale vials) and topical serum or cream – and dosed at the milligram scale, there are things a notes app won't keep straight: the reconstitution math (vial size + water → syringe units), which route you used, and how your skin or hair is actually responding. The free calculator below handles the math; a tracker keeps the route and the response visible and lets you tie outcomes to which dose and which route you were on.

OptiPin logs both routes – an injection or a topical application – and every dose lands on a timeline you can actually read. Work out the syringe units for an mg-scale vial with the free OptiPin peptide calculator, then log the dose in the app.

What the OptiPin GHK-Cu tracker does

Dose log + reminders

Record each injection or topical application on your own cadence and get reminded on the due day so a dose never slips.

Injection-site rotation

Track which site you used last so you can rotate abdomen, thigh and other SubQ sites consistently.

Side-effect logging incl. flushing

Note temporary skin flushing, injection-site stinging or redness and other effects, and see how they line up with each dose.

Skin & hair progress notes

Log the specific outcome you care about – skin, hair, healing – so a trend lines up against actual dosing over time.

Vial runout warnings

Log the reconstituted mg-scale vial and OptiPin estimates remaining doses and an empty date, warning before you run out.

CSV import & export

Bring an existing dose history in from a spreadsheet, or export your log to share with a clinician.

Running GHK-Cu as part of a skin or healing stack? OptiPin tracks it next to BPC-157 and TB-500 on one timeline. For the topical-vs-injectable evidence, half-life and reconstitution math behind the molecule, see the GHK-Cu reference.

Free dose tools for GHK-Cu

Calculators that pair with tracking – no app needed to use them:

Peptide blend calculator – splits a multi-compound vial into per-dose units, built for the GLOW (GHK-Cu + BPC-157 + TB-500) and KLOW (GLOW + KPV) stacks.
Reconstitution calculator – turns mg-scale vial size + bacteriostatic water into exact syringe units (and works in reverse). The reconstituted solution is blue from the copper.
Half-life visualizer – see how doses sit against GHK-Cu's short reported plasma half-life.
GHK-Cu reference – topical-vs-injectable evidence, the blue color, half-life and the reconstitution math, with sources.

One app for everything you're on

The real advantage of OptiPin is that GHK-Cu doesn't live in isolation. If you're also running BPC-157, TB-500, a GLP-1, TRT or a supplement stack, all of it sits in one place with a single timeline and one set of insights – instead of fragmented across a notes file and your memory. That's the difference between logging a compound and actually seeing your protocol.

Not medical advice, not a dose, not a sourcing guide. Topical copper-peptide skincare is well established; injectable GHK-Cu is unapproved with little human evidence. OptiPin records and reminds – it does not recommend a dose, a route, or whether to use GHK-Cu, and does not endorse obtaining research-grade or compounded injectable material. The reconstitution tools above are arithmetic for whatever a clinician specifies. Discuss any peptide with a qualified clinician.

FAQ

Is there an app to track GHK-Cu?

Yes – OptiPin. You log each injectable or topical copper-peptide dose, rotate sites, note side effects like temporary flushing, track skin and hair progress, and get runout warnings. It's on iPhone, stores data on-device and needs no account.

Is GHK-Cu approved?

No, not as an injectable. Topically, Copper Tripeptide-1 is a legal cosmetic ingredient; as an injectable drug GHK-Cu is not FDA-approved and is sold as a "research chemical" with no verified purity, sterility or dose accuracy. See the GHK-Cu reference.

Injectable vs topical – can it track both?

Yes. GHK-Cu is run both as a SubQ injection (reconstituted from mg-scale vials) and as a topical serum or cream. OptiPin logs either as a dose on the same timeline, so you can tie skin and hair outcomes to whichever route you used.

Can OptiPin help reconstitute GHK-Cu vials?

OptiPin logs the vial and each dose you enter and warns before the vial runs out; it does not do the reconstitution arithmetic. Injectable GHK-Cu ships as a lyophilized powder in larger mg-scale vials (commonly 50 mg) because it is dosed in milligrams; the free OptiPin peptide calculator on the web turns vial size and water volume into syringe units. It's arithmetic only, not a dose recommendation. The solution is blue from the copper.

Can it track the GLOW or KLOW stack?

Yes. GHK-Cu is the core of the GLOW blend (GHK-Cu + BPC-157 + TB-500) and the KLOW blend (GLOW + KPV). OptiPin tracks a blend as separate compounds, each with its own schedule, dose log and vial inventory, on one timeline. The free peptide blend calculator on the web splits the per-dose units. This reflects community practice, not clinical guidance.

Educational only, not medical advice. Topical copper-peptide skincare is established; injectable GHK-Cu is unapproved with little human evidence. OptiPin is a tracking tool and does not provide dosing or treatment advice, nor endorse obtaining research-grade material. Discuss any peptide with a qualified clinician.
