Skin & Coat

GHK-Cu · Topical serum + oral dropper

A copper-peptide protocol for the skin problems that come with age — coats gone thin and brittle, scrapes that take weeks to close, itchy patches he won't leave alone. Topical plus oral, matched to his weight.

Nothing ships until a licensed vet reviews your dog's file.

Dosing, by weight

Dosing is weight-banded — small, medium, large and giant dogs get different amounts — and the final dose is set by the reviewing veterinarian from your dog's file, not by a chart. We'll publish the protocol numbers here once our reviewing vets have signed off on them.

A dose is never shown here without a real veterinary protocol behind it.

Before you decide

Is it safe?
Research in dogs is early. The reviewing vet says so, and declines when it doesn't fit.
Every batch we ship will be third-party tested, with the report published.
Not for pregnant dogs, active cancer, or dogs under two.

Fair questions

Is the topical safe if he licks it?

The serum is formulated for dogs who groom, but you'll get application guidance — where, when, and how much — with the first shipment. If he's a determined licker, tell the vet.

Could the skin problem be something else?

Yes — allergies, thyroid, and parasites all masquerade as coat problems. That's exactly what the vet review is for, and why we ask for his history rather than just shipping.

Will his coat actually get thicker?

We can't promise that, and we won't. What we can promise is a vet who looks at his case honestly and says no if this isn't the fix.
