Dogs

No animal sits at the center of the pet-peptide conversation quite like the dog. Here is why the canine file runs deep, what the research actually examined, and where owner curiosity lands first.

GHK-Cu for Skin and Coat: What the Research Suggests

The copper peptide from human plasma that became a skincare staple: what decades of Pickart-era research examined, why skin-barrier biology pulls in dog and horse people, and what to ask your vet.

GHK-Cu

Three amino acids and a copper atom, studied since the 1980s. GHK-Cu built its reputation in skin and connective-tissue research, and the coat-quality conversation grew straight out of that work.

Glutathione

Every cell in your dog, cat, or horse already makes it. Researchers have spent decades asking what happens when they can't make enough.

Horses

No companion animal has a deeper peptide paper trail than the horse. Decades of performance-horse medicine turned tendon and ligament research into its own industry, and TB-500 sits at the top of the equine reading list.

KPV and Gut Health in Cats and Dogs: The Emerging Science

A three-amino-acid fragment borrowed from the body's own calming signal has become one of the most talked-about peptides in pet-owner gut-health circles. Here is what the lab work actually shows, and what to ask your vet before the excitement runs ahead of the evidence.

KPV

Three amino acids clipped from a hormone your pet's body already makes, and one of the more studied gut-immune peptides in the preclinical literature. Here is what the mouse colitis work actually examined, and why digestive-upset owners keep bringing it up.

TB-500

A lab-made copy of a peptide your animal's body already produces. TB-500 is a synthetic fragment of thymosin beta-4 studied for cell migration and soft-tissue maintenance, with an unusually deep horse literature courtesy of the racing world.
