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, reconstitute mg-scale vials with the built-in calculator, 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. A tracker makes all of that visible, and lets you tie outcomes to which dose and which route you were on.

OptiPin handles both sides natively - log an injection or a topical application, reconstitute mg-scale vials in-app, and every dose lands on a timeline you can actually read.

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.

Built-in reconstitution math

Pick GHK-Cu and OptiPin converts mg-scale vial size + water into exact syringe units - no hand math for the milligram dosing.

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, reconstitute mg-scale vials with the built-in calculator, 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?

Yes. Injectable GHK-Cu ships as a lyophilized powder in larger mg-scale vials (commonly 50 mg) because it is dosed in milligrams; the built-in reconstitution calculator turns vial size and water volume into exact syringe units (the same tool is free on the web). 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 peptide blend calculator 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.
