Skincare & research peptideGHK-Cu tracker
GHK-Cu, tracked privately: topical routine or injection.
GHK-Cu, the copper peptide, is one people use topically for skin and (less commonly) as an injection. It's also a popular add-on for anyone bothered by loose skin during GLP-1 weight loss. Lirea keeps a private record of how you use it, kept on your phone, with no account.
One email on launch day, and nothing else. The app itself never asks for one.

What you'll track
Made for how you actually take GHK-Cu.
Topical serum (daily) or a reconstituted subcutaneous injection.
Topical routine or injection, your choice
Lirea tracks GHK-Cu either way: a simple AM/PM skincare habit, or a reconstituted injection on a cycle. Pick the mode that matches how you use it.
Cycle on and off
Injected GHK-Cu is usually run in cycles. Lirea shows where you are in the cycle and when to take a break, so you're never guessing.
Skin alongside your GLP-1
Many people pick up a copper peptide when GLP-1 weight loss leaves skin feeling loose. Keep it in the same private place as the rest of your routine.
How your skin's responding, in context
Note changes over weeks, not days, and let the trend show, calmly, with no cloud and no sharing.
Pen & vial inventory
Whether it's a topical bottle or a reconstituted vial, Lirea tracks what you have left and (for injections) your vial's storage and reconstitution date.

Questions
GHK-Cu, tracked privately
Can Lirea track topical GHK-Cu and injectable GHK-Cu?
Yes. You can log GHK-Cu as a daily topical routine or as a cycled injection. Lirea handles both modes of the same peptide.
Is GHK-Cu the "copper peptide" in skincare?
Yes, copper tripeptide-1 is the same GHK-Cu sold in serums. Topical copper peptides are an established cosmetic ingredient; injectable use is not FDA-approved.
Does my GHK-Cu data stay private?
Yes. Everything is stored and encrypted on your device, with no account and no server in the middle.
