Peptides are short chains of amino acids — the body's own signaling molecules. Below are the ones actually used in dogs, cats and horses, grouped by what they support. In plain language, no hype.
Tendon, ligament, joint and post-surgery support.
The best-known animal peptide. Studied for joint comfort, tendon and ligament repair, and gut-lining support — the go-to starting point most owners hear about first.
A soft-tissue specialist with the longest track record in horses. Studied for tendon, ligament and muscle recovery after strain or injury.
The most clinically studied option for joint and mobility support in dogs and horses — and the easiest to give, since it's oral and food-friendly.
A long-acting IGF-1 analog studied for cell growth and muscle/tissue recovery. A higher-intensity research compound — always vet-guided.
Growth-factor compound — research-only, vet guidance essential.
A growth-hormone-releasing research peptide studied for recovery and vitality pathways in aging research. Regulated-class — strictly research-framed.
Regulated-class secretagogue — research-only, vet guidance essential.
A GHRH-analog research peptide studied for growth-hormone-axis and recovery pathways. Regulated-class — strictly research-framed.
Regulated-class secretagogue — research-only, vet guidance essential.
Digestive comfort and gut-lining support.
The best-known animal peptide. Studied for joint comfort, tendon and ligament repair, and gut-lining support — the go-to starting point most owners hear about first.
A small anti-inflammatory peptide studied for digestive comfort and for calming itchy, irritated skin. Absorbed well by mouth via gut transporters.
Wound healing, skin and a shinier coat.
A small anti-inflammatory peptide studied for digestive comfort and for calming itchy, irritated skin. Absorbed well by mouth via gut transporters.
A copper peptide studied for wound healing and skin & coat quality, including scar remodeling after surgery.
Used with caution in cats — always vet-guided.
The classic coat-and-skin nutrient — biotin has the longest everyday track record of anything here, widely used in coat, skin-barrier and hoof/nail support.
Everyday resilience and recovery support.
An immune modulator studied for supporting resilience during recovery and convalescence, and after chronic illness.
Healthy-aging and vitality support.
Explored in healthy-aging protocols for older pets, studied for its effects on telomere and sleep-rhythm (melatonin) pathways. Evidence is early.

A cellular coenzyme central to energy metabolism, studied in healthy-aging research for mitochondrial function and vitality in older animals.
A neuropeptide studied for cognitive and neuroprotective pathways — explored in healthy-aging and senior-pet cognition research. Evidence is early.
A mitochondrial-derived peptide studied for metabolic and anti-aging biomarkers. Newer and still research-stage in animals.
