Peptides for Dogs Dosage Chart — What Sets the Amount

There is no official, veterinary-sanctioned dosage chart for peptides in dogs — not for BPC-157, not for TB-500, not for KPV. These compounds are not FDA-approved veterinary drugs, so there is no approved label dose the way there is for carprofen or gabapentin. Body weight is the variable most owners search for, and it is genuinely the starting point that almost every peptide protocol scales from, but it is one input among several. The amount an individual dog receives is a decision for you and your veterinarian, working from the specific product in your hand — not a number copied from a forum thread or a human bodybuilding chart.

What this page does instead is give you the reference an honest chart would have to be built on: how weight-based scaling actually works, what BPC-157, TB-500 and KPV each are and why owners reach for them, and how to read a peptide label so you know what you are holding before you ask your vet about it. pawgen makes K9-REPAIR, a BPC-157 and TB-500 formulation made for dogs and dosed by body weight, which is the format most owners are looking for when they search for a chart in the first place.

Why one chart can't cover every dog and every peptide

A dosage chart looks authoritative because it is a grid. The problem is what the grid leaves out.

A number is only meaningful when it is attached to a specific peptide, at a specific concentration, in a specific formulation, for a specific dog — which is exactly why the useful conversation happens with your veterinarian rather than with a printable table.

The variables that move the answer:

• Body weight and body composition. A lean, muscular dog and an overweight dog of identical weight are not the same physiological target. Many drugs scale to lean mass, not scale mass.
• Which peptide. BPC-157, TB-500 and KPV are structurally unrelated molecules with different sizes, half-lives and mechanisms. Amounts are not transferable between them, and a chart that lists them in the same column with the same figures is telling you the author did not check.
• Formulation and route. An oral capsule, a stabilised oral liquid and a reconstituted injectable behave very differently in the body. Bioavailability differs enough that the same figure means something else in each format.
• Product concentration. Two bottles can carry the same peptide at different strengths. The amount of product and the amount of peptide are different numbers.
• Goal and stage. An owner supporting a dog through the weeks after a cruciate repair is in a different situation from one managing a senior dog's day-to-day stiffness.
• Health status and other medications. Kidney and liver function, existing diagnoses, and everything already prescribed matter. This is squarely veterinary territory.
• Life stage. Puppies, pregnant dogs and nursing dogs sit outside general guidance entirely. There is no responsible chart figure for them — that conversation belongs to your veterinarian and no one else.

What BPC-157, TB-500 and KPV each are

These three come up together in searches, but they are not variations on one theme.

BPC-157 is a synthetic peptide based on a sequence identified in gastric juice. Published laboratory research has focused heavily on soft-tissue repair processes — tendon, ligament, muscle and gut tissue — and on angiogenesis, the formation of new blood vessels that carry oxygen and nutrients into healing tissue. Tendon and ligament are poorly vascularised to begin with, which is a large part of why they remodel slowly, and that mechanism is precisely why BPC-157 has drawn the attention it has. Research suggests it interacts with growth-factor signalling involved in tissue remodelling.

TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring actin-binding protein found throughout mammalian tissue. Actin is the structural protein cells use to move and reorganise. Research suggests thymosin beta-4 supports cell migration and the recruitment of repair cells to a site of tissue damage. In practical terms, BPC-157 and TB-500 are studied along complementary lines — one weighted toward local signalling and blood supply, the other toward cell mobility — which is why they are so commonly paired.

KPV is a tripeptide — lysine, proline, valine — corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone. Published work on KPV centres on inflammatory signalling, particularly in the gut and skin, which is why owners dealing with digestive or dermatological issues ask about it rather than owners dealing with a torn ligament.

Peptide	What it is	What research suggests it interacts with	Why owners look at it	In K9-REPAIR?
BPC-157	Synthetic peptide based on a gastric sequence	Tissue remodelling signalling, angiogenesis	Tendon, ligament and joint recovery support	Yes
TB-500	Synthetic fragment of thymosin beta-4	Actin binding, cell migration	Soft-tissue and mobility support	Yes
KPV	Tripeptide fragment of alpha-MSH	Inflammatory signalling pathways	Gut and skin concerns	No

None of these compounds is an FDA-approved veterinary drug, and none of them treats or cures any condition. What can be said honestly is that the mechanisms are well described in the literature, the science is advancing quickly, and owners are adopting the joint-and-tendon pairing in real numbers.

How body weight scaling works — and where it stops working

When a chart is organised "by weight," it is applying a simple idea: a larger animal has more tissue, more blood volume and more clearance capacity, so the amount scales upward with mass. That is why weight bands are the standard format for canine supplements and why K9-REPAIR is dosed by body weight rather than sold as one-size-fits-all.

Two things owners frequently get wrong.

The first is converting a human figure to a per-pound canine figure with arithmetic. Straight linear scaling between species ignores allometry — metabolic rate does not rise in a straight line with body mass — and it ignores that a compound's distribution and clearance can differ between species entirely. A human protocol divided by bodyweight ratio is not a canine protocol. It is a guess wearing a decimal point.

The second is treating the weight band as the whole answer. Weight sets the ballpark. Your dog's diagnosis, current medications, kidney and liver function, age and the specific product concentration determine whether the ballpark applies. That is why every question that starts "how much should I give per pound" ends in the same place: talk to your veterinarian with the actual product and its label in front of you. A good vet will not be offended by the question, and increasingly they are not unfamiliar with it either.

The KPV per-pound question, answered plainly

This is one of the most searched peptide dosing questions for dogs, so here is the honest answer: there is no established per-pound KPV figure for dogs published by any veterinary regulatory body, and anyone printing one is presenting an estimate as a standard. KPV is typically discussed in the context of gut and skin inflammation rather than orthopaedic recovery, and if that is your dog's issue, the productive route is a diagnostic conversation with your vet — inflammatory bowel disease, food-responsive enteropathy and allergic skin disease all look similar from the outside and need distinguishing before anything is added.

If your dog's problem is a limp, a cruciate injury, a post-surgical recovery or the slow mobility loss of a senior dog, KPV is not the molecule the research points you toward. BPC-157 and TB-500 are, and that pairing is what K9-REPAIR is built around.

How to read a peptide label before you go looking for a chart

The supplement aisle rewards vagueness, so apply pressure to the label rather than to the science.

• Named peptides at stated amounts. If a product lists peptides in a proprietary blend without disclosing how much of each is present, no dosage chart can be meaningful — you do not know what you are dividing.
• Third-party testing and a certificate of analysis. Identity and purity should be verified by an independent lab, and the COA should be available to you rather than described in marketing copy. pawgen publishes third-party testing for K9-REPAIR for exactly this reason.
• A formulation with a purpose. Kitchen-sink chews that list fifteen trending ingredients at trace amounts are optimised for the back of the bag, not for the dog. A focused formulation tells you what it is for.
• Weight-based dosing that exists. A product that ships without any weight guidance is asking you to invent one.
• A guarantee that costs the company something. K9-REPAIR carries a 60-day money-back guarantee and ships direct to your door, which puts the risk of trying it where it belongs.

Key Takeaways

• No official peptide dosage chart for dogs exists, because BPC-157, TB-500 and KPV are not FDA-approved veterinary drugs with approved labels.
• Body weight is the correct starting variable, but formulation, concentration, route, goal, medications and health status all move the answer.
• BPC-157, TB-500 and KPV are unrelated molecules — amounts are never transferable between them.
• Human protocols cannot be converted to a canine per-pound figure with arithmetic; species scaling does not work that way.
• There is no responsible published figure for puppies, pregnant dogs or nursing dogs. That is a veterinary conversation, full stop.
• Judge a product on named ingredients, disclosed amounts, third-party testing and a published COA before you judge it on a chart.

K9-REPAIR pairs BPC-157 and TB-500 in a formulation made for dogs, dosed by body weight, third-party tested, backed by a 60-day money-back guarantee and shipped direct — you can read the full formulation and testing detail at pawgen.

One last thing, and it matters more than any of the above. Your veterinarian owns the diagnosis and the treatment plan. Imaging, surgical repair, prescribed pain control and a structured rehab programme are what actually resolve a torn cruciate or a damaged tendon, and nothing here is a reason to delay a surgical consult, skip a recheck or stop a medication your vet prescribed. Peptides operate in the space that proper veterinary care creates — bring the product and its label to your next appointment, and make the decision together.
