# BPC-157 for dogs: where to buy it and what to check first

Start with your vet, then buy BPC-157 for dogs from a seller that shows purity testing, a dose by body weight and a cold chain.

You can buy BPC-157 for dogs online from research-peptide sellers, including Canitide, which sells it two ways: REPAIR, a pre-mixed cartridge of BPC-157 and TB-500 for a dial-dose pen, and GUT, an oral capsule of BPC-157 arginate and KPV. There is no veterinary BPC-157 drug. Every BPC-157 product on the market, ours included, is a research-use product that is not FDA-approved, and no controlled trial of BPC-157 in dogs has been published. The first step is a conversation with your veterinarian. The second is choosing a seller that shows what is in the vial and how much to give a dog of your dog's weight.

## Talk to your veterinarian first

A limp, a sore back or a loose stool can have causes that BPC-157 has nothing to do with. A torn cruciate, a disc problem or a mass needs a diagnosis before anything else. Ask your vet to examine the dog, name the problem and set out the standard options. Then tell them you are considering BPC-157 and ask whether they see a reason not to. Some vets have used peptides in working and sporting dogs. Others have not and will say so. Either answer is useful. Bring the certificate of analysis for the product you are considering so they can see the purity figure and the amount per dose.

## What BPC-157 has been studied for

BPC-157 is a 15-amino-acid fragment of a protein found in gastric juice. The research base is mostly rodent and cell work from one group in Zagreb, with a smaller number of independent studies.

- **Rat Achilles tendon.** In a 2003 study, rats with a transected Achilles tendon were given BPC-157 by intraperitoneal injection once a day at 10 µg/kg, 10 ng/kg or 10 pg/kg. Treated tendons scored better on biomechanical testing, function and tissue structure than untreated controls.
- **Rat tendon cells.** A 2011 study on cultured rat Achilles tendon fibroblasts found that BPC-157 increased outgrowth from tendon explants, cell survival under oxidative stress, and cell migration. It did not increase proliferation on its own.
- **Rat tendon, BPC-157 beside TB-500.** A 2026 study gave rats BPC-157 at 10 µg/kg a day, TB-500 at 60 µg/kg a day, or both, for four weeks after Achilles surgery. TB-500 produced the clearest gain in mechanical strength. BPC-157 improved some structural scores without reaching significance. Giving both did not add to either alone.
- **Rat and beagle pharmacokinetics.** A 2022 study dosed Sprague-Dawley rats and beagle dogs intravenously and intramuscularly. In dogs the intramuscular doses were 6, 30 and 150 µg/kg, with a repeated 30 µg/kg dose for seven days. The parent peptide had an elimination half-life under 30 minutes in both species. Intramuscular bioavailability was 45 to 51 percent in dogs. The peptide was broken down to its amino acids and cleared mainly through the kidney and liver.

That beagle study is the only canine data. It measured where the peptide goes and how fast it leaves. It did not test whether it helps a dog heal. Owners use BPC-157 for tendon and ligament recovery, post-surgical support and gut upset, and those uses rest on the rodent studies above, not on a dog trial.

## What to check before you buy

Research-peptide sellers vary in what they disclose. Check for these things before paying.

1. **A certificate of analysis for the lot you are buying.** It should name the lab, show a purity figure from HPLC, and show mass spectrometry confirming the peptide's identity. A generic certificate with no lot number is not enough.
2. **The amount of peptide in each dose.** A vial labeled "5 mg" tells you what is in the vial, not what your dog gets. A seller who gives a dose for a dog's weight has done the arithmetic for you. A seller who does not leaves you to reconstitute, calculate and draw up.
3. **The form.** Lyophilized powder has to be reconstituted with bacteriostatic water and kept cold. Pre-mixed cartridges arrive ready to dial. Oral capsules are the simplest form, but an oral product is a gut product, not a tendon product.
4. **Storage and shipping.** Reconstituted BPC-157 is kept refrigerated. Ask how the product ships and how long it holds after opening.
5. **Who the product is sold to.** Most sellers sell for research use only and say so. That is the legal status for all of them. A seller claiming that BPC-157 is approved, or that it treats a named condition, is making a claim no regulator has accepted.
6. **Whether the seller names the research model.** A study in rat tendon is a study in rat tendon. A page that calls the tendon research "proof" without saying it was done in rats is not a page to trust.

## Forms you will see

| Form | What you do | Best suited to |
| --- | --- | --- |
| Lyophilized vial | Reconstitute, calculate the dose, draw up with an insulin syringe | Owners who are comfortable with the math and storage |
| Pre-mixed cartridge | Load the pen, dial the units on your dog's card, inject | Owners who want a known dose without the arithmetic |
| Oral capsule | Give with food | Gut use; not a route for tendon or joint work |

## Dose by weight band

Canitide gives every product in units on a dial-dose pen, where one unit is 0.01 mL. The bands below come from the mg/kg ranges in the animal research, scaled to four canine weight bands and rounded to whole units. The beagle study used intramuscular doses between 6 and 150 µg/kg, and the rat tendon studies used 10 µg/kg a day. Our REPAIR bands sit inside that range.

| Weight band | REPAIR (BPC-157 + TB-500), five days a week | GUT (oral BPC-157 arginate + KPV), daily |
| --- | --- | --- |
| Under 20 lb | 6 units | 1 capsule |
| 20 to 50 lb | 9 units | 2 capsules |
| 50 to 90 lb | 12 units | 2 capsules |
| 90 lb and up | 15 units | 2 capsules |

Run REPAIR for the period your vet agrees to, alongside the rest and rehab plan they set, then stop and reassess. Keep the dose on the card. If a dog seems off after a dose, stop and call the vet. The full dosing page, with the arithmetic behind each band, is at [BPC-157 for dogs dosing](/dosing/bpc-157-for-dogs/).

## Where Canitide fits

We built the pen around measurement, because that is where most of the work of using a peptide at home sits. A pre-mixed cartridge with a weight-band card removes reconstitution, unit conversion and syringe reading. Each lot ships with its certificate of analysis. The product page for the cartridge is [Canitide REPAIR](/products/canitide-repair/).

You do not have to buy from us. If you buy elsewhere, apply the checklist above to the seller. Whatever you buy, bring the certificate to your vet, keep the dose written down, and judge the result by what the dog does on walks and stairs over weeks, not by what any seller says.
