BPC-157
The most-studied recovery peptide in the animal literature. A short protein fragment modeled on a stomach protein, anchored by decades of rodent research and one well-known pharmacokinetic study in beagle dogs.

Somewhere between the journals and the forums there's a gap. The studies on peptides in dogs, cats, and horses are written for scientists, and the owner conversations are scattered across threads forty pages deep. This library sits in the gap. We read the research, we follow what owners report, and we write it up so a person with a senior dog and twenty minutes can actually use it.

BPC-157: What the Recovery Research Actually Shows
No peptide gets dog owners talking like BPC-157. Here is where the research actually came from, what it examined, and what is still unknown.
5 min read, and no science degree required.
The compound files
One file per peptide: what it is, what the animal research says, what owners talk about.

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.

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.

The species files
The same research, sorted the way you think about it: by your animal.

Cats
The feline file: cats turn up all over the gut-and-immune literature, and KPV sits at the top of the cat-owner reading list.

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.

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.
