GHK-Cu

GHK-Cu is a copper-binding tripeptide that owners most often ask about in relation to coat condition, skin quality, and healthy ageing.

GHK-Cu is a naturally occurring tripeptide (glycyl-L-histidyl-L-lysine) that binds copper and is involved in collagen and extracellular-matrix biology. Owners most often ask our veterinary team about GHK-Cu when a horse, dog, or cat has a dull or thinning coat, skin that seems slow to settle, or when they are simply looking to support an older animal's condition. What owners describe wanting is usually general appearance and comfort rather than treatment of a specific disease. Coat and skin changes can be an early sign of something else — thyroid, nutritional, parasitic, or allergic — so our supervising veterinarian looks for an underlying cause before considering anything else. Any protocol is set individually. GHK-Cu is not approved by the FDA for use in animals and does not replace veterinary care.

Veterinarian-Supervised Program

Every peptide protocol in this section is set and overseen by our supervising veterinarian. Nothing on these pages is a diagnosis, a prescription, or a substitute for examining your animal — dosing is determined individually after veterinary review of your pet's species, weight, age, medications and health history. Peptides are used alongside, never instead of, care from a licensed veterinarian. These products are not approved by the FDA for use in animals. If your animal is unwell, injured, or showing new symptoms, contact a veterinarian first.
