Horses are a genuinely different case from dogs and cats — both in what kind of injuries drive interest, and in a compliance layer that simply doesn't exist for companion pets at home.
Notice a theme? A lot of the momentum behind animal-peptide interest is spilling over from human research.

Peptide research interest in horses tends to sit adjacent to that existing field, not as an established equine treatment in its own right. See our research index for what's actually documented by compound.
This is the piece that has no equivalent for a dog or cat at home: any horse competing under a governing body — FEI internationally, USEF in the United States, and comparable organizations elsewhere — is subject to a prohibited and controlled substances list, and violations carry real consequences including disqualification and suspension. These lists are updated periodically and commonly restrict broad categories that can include peptide- and protein-based substances alongside traditional medications. This page is not a substitute for checking the current list from the relevant governing body directly, and for a competing horse, that check needs to happen before your veterinarian, not after.
Because PRP and stem cell approaches already have a real foothold in equine orthopedic care, an equine veterinarian evaluating a tendon or ligament injury is often already thinking in terms of regenerative options generally — useful context for how they might reason about newer approaches, and a good starting point for a conversation rather than a separate topic.
Beyond the clinical picture, bring the competition question explicitly if it applies: is this horse currently competing, under which governing body, and has the current prohibited substances list been checked? Our talking to your vet guide covers the rest of that conversation.
For the legal and regulatory framework beyond competition rules specifically, see regulatory status.
Understanding the research is step one. The real next step is a conversation with a licensed veterinarian who can tell you where your pet's situation actually falls within it.
