> Plain facts on peptides for horses: what is known, what isn't, and which sellers prove what's in the product. Not veterinary advice, and we never recommend a dose.

Key facts: no peptide here is FDA-approved for animals, and no trial testing any of them as a treatment in horses has been published. None of the 4 sellers shows a lab document for what it sells. Some links are paid and marked; payment never changes a ranking.

## Peptides
- [BPC-157 for horses](https://peptidesfor.horse/peptides/bpc-157/): a short chain of amino acids that has been studied in the lab since the 1990s, mostly for gut and tissue healing

## Guides
- [BPC-157 vs TB-500 for horses: how do they compare?](https://peptidesfor.horse/compare/bpc-157-vs-tb-500/): BPC-157 and TB-500 compared for horses: what each is, the evidence, FEI status, detection and how they are sold. There is no winner, and here is why.
- [Is BPC-157 banned in horse competition?](https://peptidesfor.horse/learn/is-bpc-157-banned-in-competition/): BPC-157 is not named on the FEI list, but not named does not mean allowed. TB-500 is banned. What Banned means, who is responsible, and USEF and racing rules.
- [Are peptides safe for horses?](https://peptidesfor.horse/learn/are-peptides-safe/): Nobody knows if peptides are safe for horses. The unknowns, label accuracy, injecting at the yard, nasal sprays, reading a lab report and what to watch for.
- [Racehorses and peptides: HISA rules, testing and injuries](https://peptidesfor.horse/disciplines/racing/): HISA bans thymosin and unapproved substances at all times, with testing out of competition too. What the rules say, common racehorse injuries, and vet care.
- [Eventing, dressage and jumping: FEI peptide rules and injuries](https://peptidesfor.horse/disciplines/eventing/): TB-500 is Banned on the 2026 FEI list and other peptides fall under its catch-all clause. How FEI testing works, common sport horse injuries, and vet care.
