🐈 Feline Peptide Reference
Veterinary peptide research structured for cats. 4 peptides with potential relevance to common feline conditions. All entries include explicit evidence boundaries and extra-label use disclaimers.
Common Feline Conditions with Peptide Research
BPC-157 (Veterinary)
Extensive animal studies (primarily rodents) show accelerated healing of tendons, ligaments, muscle, bone, and gastric mucosa. No published veterinary clinical trials in dogs, cats, or horses. All evidence is extrapolated from rodent models. FDA placed BPC-157 on the Category 2 compounding prohibited list in 2024. This applies to veterinary compounding as well. Obtaining BPC-157 for veterinary use may be legally and practically difficult in the US.
- •All evidence from rodent models — species translation uncertain
- •No established veterinary dosing or safety data
- •FDA Category 2 listing may prevent legal veterinary compounding in the US
- •Banned by FEI and most racing/performance organizations; competition horses may test positive
- •Should not replace standard rehabilitation protocols (rest, controlled exercise, PRP, shockwave) for tendon/ligament injuries
- •Theoretical interaction with NSAIDs commonly used in equine orthopedic and gastric ulcer management
- •May interact with NSAIDs commonly used in veterinary orthopedics
- •Should not delay or replace established standard-of-care treatments with proven efficacy
- •Document extra-label use and obtain informed consent
No established veterinary dosing exists. The doses mentioned in rodent research literature (variously reported as 10 mcg/kg/day) have not been validated in dogs, cats, or horses. Pharmacokinetics, optimal dose, route, frequency, and safety margins are unknown for veterinary species. Any dosing decision is entirely at veterinary discretion with informed owner consent.
GHK-Cu (Veterinary)
GHK-Cu has documented wound-healing effects in vitro and in small animal models. Some veterinary topical products contain copper peptides. No controlled veterinary clinical trials published. No veterinary data exists for injectable or systemic GHK-Cu use. Only topical application has any theoretical basis in veterinary wound care.
- •Topical use only in veterinary context — no injectable veterinary data
- •Copper sensitivity possible in some animals
- •Avoid use in animals with Wilson's disease or copper metabolism disorders
- •Should not delay or replace established standard-of-care treatments with proven efficacy
- •Document extra-label use and obtain informed consent
Thymalin (Veterinary)
Thymic peptides have been studied in aged animals, primarily in Soviet-era Russian literature that has not been replicated in Western peer-reviewed journals. No modern veterinary clinical trials exist. Evidence quality is extremely limited.
- •Immunomodulatory effects in animals not well-characterized
- •Potential for immune overstimulation in animals with autoimmune conditions
- •No pharmacokinetic data in dogs or cats
- •Should not delay or replace established standard-of-care treatments with proven efficacy
- •Document extra-label use and obtain informed consent
LL-37 (Veterinary)
LL-37 is a human cathelicidin antimicrobial peptide with broad-spectrum activity demonstrated in vitro. Veterinary relevance is theoretical — no published clinical trials in animals. Natural cathelicidins exist in most mammals.
- •No veterinary pharmacokinetic or safety data
- •Potential for local irritation at application site
- •Antimicrobial peptides may trigger immune responses in some animals
- •Human-origin peptide may trigger antibody formation in animals; potential for reduced efficacy on repeated use and theoretical immune complex risk
- •Should not delay or replace established standard-of-care treatments with proven efficacy
- •Document extra-label use and obtain informed consent
