Laminitis is an emergency, so call your vet now. No peptide has been shown to help, and we don't track any peptide sold for it. The Merck Veterinary Manual says no current drug stops laminitis starting. Vets focus on pain relief, foot support, cold therapy in the early stages and treating the cause.
Think it's laminitis? Call your vet now
Do not wait to see if it improves, and do not look for a product first. The MSD Veterinary Manual calls acute laminitis a medical emergency because the coffin bone can shift quickly. Laminitis weakens the tissue that holds the bone inside the hoof, and the result can range from short-term lameness to an injury that ends a career or a life. Look for these signs:
- Shifting weight, or standing with the front feet out ahead and weight back
- Reluctance to move or lift a foot
- A short, crouched stride
- Warm hooves, most of all near the coronary band
- A strong, pounding pulse at the foot
- A dull horse that eats poorly, trembles or lies down a lot
What should I do while I wait for the vet?
Keep it simple and ask your vet on the phone. Tell them what you see and when it started. Ask before you give any medicine, and ask whether to stand the feet in ice water, because the MSD manual says cold therapy may suit some horses. Ask whether to move your horse to soft footing, how much it should walk, and whether to take it away from grass or grain. Your vet and farrier will advise on shoes.
What causes laminitis?
Hormones are the most common cause today. Merck calls endocrine disease probably the most common underlying cause, and says high insulin linked to equine metabolic syndrome (EMS) or PPID is what drives it. Its EMS chapter puts insulin-linked laminitis at about 90% of cases in the general horse population. Other routes need different care, so your vet has to find which applies.
| Type | Common triggers | What it means |
|---|---|---|
| Endocrine | EMS, PPID, rich grass | Often comes back unless insulin is controlled |
| Overload or severe illness | Too much grain or lush grass, colitis, a retained placenta, serious infection | The illness needs urgent treatment too |
| Supporting limb | One leg carrying too much weight because the opposite leg is badly hurt | Watch the good leg in any horse that won't use the other |
| Others | Black walnut shavings. Corticosteroids are also linked, though evidence is anecdotal. | Tell your vet about all recent medicines |
What do vets and farriers do for laminitis?
Your vet treats the pain, supports the foot and goes after the cause. Merck says there is no universally accepted standard treatment for acute laminitis, so plans vary. These are the usual parts of one:
- Anti-inflammatory pain relief
- Foot support, using soft materials or hoof boots to support the frog or sole and take load off the damaged tissue
- Cold therapy in the early stages. Merck calls it the most effective way to reduce damage at that point.
- X-rays, which help less in the acute phase but show the bone's position in chronic cases
- Therapeutic trimming and shoeing, which Merck calls the main treatment for chronic cases, planned by your vet and farrier together
- Surgery on the deep flexor tendon if the bone keeps rotating and pain persists
How do I stop it happening again?
Find and control the cause. Ask your vet to test insulin and check for PPID. For EMS, Merck says diet matters most: severe limits on grazing, no grain or treats, and low-sugar hay. Exercise helps once the laminitis has resolved. For PPID, pergolide is the main drug, and FDA-approved tablets are available on prescription. Regular hoof care matters even in a horse that is not lame. Our guide to weight and condition explains the insulin side.
What is known about peptides for laminitis?
Nothing that should change what you do. We don't track any peptide sold for laminitis, but owners ask, often after reading about BPC-157 or TB-500 for tissue repair. Neither is officially tested in horses, and neither is FDA-approved for animals. No clinical trial of either in horses appears in PubMed, and BPC-157 returns no PubMed results at all for horses.
Merck says no currently available drug or agent stops the onset of laminitis. If a seller says otherwise, they are claiming more than the science does. FDA treats a product sold to treat disease in animals without approval as an unapproved drug.
There are also specific risks. A horse in pain needs care now, and time spent on an untested product is time the bone can move. Injecting at the yard adds a risk of infection to a horse that is already unwell. Read about the safety unknowns if you are weighing anything up, and tell your vet about every product your horse has had.
Questions for your vet and farrier
Laminitis care is a long job, so agree the plan early. These questions help:
- What type of laminitis is this, and what caused it?
- Has the bone moved, and when should we take X-rays?
- What should my horse stand on, and how much can it move?
- Should we test insulin and PPID, and when?
- What should my horse eat now, and how will that change?
- How will we know it is getting better?
What vets usually do
Pain relief, corrective shoeing, diet change, and treating the cause, often a hormone problem.
Peptides owners ask about
No peptide is sold for this that we track.
A video call with a licensed vet helps you decide how urgent it is and what to tell your own equine vet. Colic or a horse that won’t put weight on a leg needs a vet visit now. Start a vet call Paid link
Questions horse owners ask
Can a peptide stop laminitis?
Nothing shows that it can. Merck says no currently available drug or agent stops laminitis starting. BPC-157 and TB-500 have not been officially tested in horses. Call your vet at the first signs, because prompt care is what matters.
How urgent is laminitis?
Very. The MSD Veterinary Manual calls acute laminitis a medical emergency because the coffin bone can shift quickly. Call your vet straight away, even if your horse only looks a little footsore. The outlook stays guarded until recovery is complete.
Can my horse recover from laminitis?
Many outcomes are possible, from short-term lameness to a career-ending or life-threatening problem. Merck gives a guarded to poor outlook for severe acute cases. Early treatment and control of the cause give your horse the best chance.
Is laminitis caused by too much grass?
Often grass is the trigger, but the problem underneath is usually insulin. Merck says endocrine disease is probably the most common underlying cause. Ask your vet to test insulin and PPID so you can plan grazing safely.
Can a horse that isn't fat get laminitis?
Yes. Merck notes that a lean form of equine metabolic syndrome is described, and that a horse without obesity can still have insulin problems. Severe illness and overloading one leg can also cause it, whatever your horse's weight.
