Vet guidance

Talk to your vet first. They know things about your pet that we never could — and the conversation matters more than the product. We'd rather you start later, with their blessing, than start sooner without it.

Every pet is different.

The Science

What is TB-500?

Short answer: it's a peptide. A chain of about 17 amino acids — the same building blocks that make up the proteins in your dog's joints, your cat's coat, your own muscles. TB-500 is a synthetic fragment of Thymosin Beta-4, a protein naturally produced in nearly every cell in the body.

Researchers have studied TB-500 in animal models for its role in cellular migration, tissue remodeling, and muscle and tendon recovery. It's frequently discussed alongside BPC-157 in peptide research, and the two are often explored together in longevity and regenerative protocols.

What we're not going to do is tell you it's a miracle. The research is real and ongoing. The compound is real and well-characterized. What it does for your specific pet, on a specific day, is a conversation for you and your vet — not a sales pitch from us.

The Specs

Nothing hidden. Nothing fudged.

If you wouldn't accept vague answers from your vet, you shouldn't have to accept them from us. Here's exactly what's in the bottle — and the receipts to prove it.

Who it's for

You probably know which one is yours.

Not every pet needs the same thing. But most pet parents already have a feeling about where their dog or cat fits.

Third-Party Tested

Receipts. Every batch.

Most pet supplement brands don't publish their lab results. We don't understand that. Every lot of TB-500 Capsules is independently tested by third-party laboratories — identity, purity, heavy metals, microbial. The Certificate of Analysis for your specific batch is one QR scan or one click away. Because if you can't see it, you can't trust it. And if we can't show you, we shouldn't be selling it.

How It Works

A small thing your pet does every day.

No needles. No clinic visits. Just a capsule that fits into the routine you already have — simple daily support that feels easy, familiar, and low-stress for you and your pet.
1

You give it

One delayed-release veggie capsule, given how your vet recommends. With food, with a treat — whatever works for your pet.

2

It travels

The capsule's delayed-release shell helps the peptide reach the gut intact, where it can be absorbed and circulate through the system.

3

It signals

Once circulating, BPC-157 has been studied for its role in tissue repair signaling and gut lining support — the kind of background work that doesn't show up in one day.

Simple formula

What's Inside

01 TB-500 (Thymosin Beta-4 Fragment) TB-500 is a research peptide inspired by thymosin beta-4. This row identifies the primary active peptide featured in the formula.
500 mcg
02 Microcrystalline Cellulose (filler) A plant-derived capsule filler used to help create consistent capsule volume and structure.
—
03 Delayed-Release Veggie Capsule A vegetarian capsule shell designed to delay release compared with a standard immediate-release capsule.
—
Three ingredients. That's it. No artificial colors, no flavors that mask things, no preservatives, no animal-derived capsule shell. Manufactured in a facility that follows current good manufacturing practices. We left out everything we couldn't justify keeping in.

Store in a cool, dry place

Keep away from direct sunlight and moisture. Room temperature is fine.

Keep container tightly closed

Preserves potency and prevents moisture exposure between uses.

Keep out of reach of children

And other animals. Not intended for human consumption.

Do not use if seal is broken

If the safety seal is damaged or missing, contact us and do not administer.

Easy Going

"But will my pet actually take it?"

Fair question. Some dogs swallow a capsule like a treat. Some cats have opinions about everything. Here's what works — for both kinds.

Routine tips

For Dogs

Capsule-friendly tricks for pups who love a snack.

The peanut butter trick still works. Tuck the capsule in, hand it over, watch it disappear.

Mix into wet food. Most dogs find it before they find the capsule.

Capsule-pros: place at the back of the tongue, gently close the mouth, count to three.

Always offer water after. Make it a calm moment. Praise like you mean it.

We don't print a dose on the label, and we won't print one here either. Your vet sets the routine — they know your pet's history. We just make the capsule.

Vet-first guidance

If your vet says no, please say no.

Paws & Peps is a supplement company. We're not a substitute for veterinary care, and we never want to be. Your vet has the full picture — your pet's history, their medication, their quirks. We'd rather you walk away from this product with their guidance than buy it without it. Talk to them first. Always. The conversation is the best part of the routine, anyway.

Frequently Asked

Questions about
TB-500 Capsules.

Straight answers for pet parents — from how to give capsules,
to testing, safety, and what to ask your vet.
Two main ways: hand the capsule over with a treat (most dogs), or open the capsule and mix the contents into a small bite of wet food (most cats). On purpose, we don't print a dosing schedule on the label — your vet decides that, because they know your pet's weight, age, history, and what else they're on. We're the supplement company. They're the doctor.
Our TB-500 Capsules are formulated for both. But "safe in general" and "safe for your specific pet" are different sentences. Tolerance varies, drug interactions exist, and underlying conditions can change everything. Please run it past your vet before you start — that's not a hedge, it's just the right call.
No — and we want to be totally upfront about that. TB-500 is not FDA-approved for veterinary use. Our capsules are sold as supplements, and they are not intended to diagnose, treat, cure, or prevent any disease. If a brand tells you otherwise, run.
60 capsules per bottle. The honest answer to "how long" is: depends entirely on what your vet recommends. We'd rather give you a real answer ("ask them") than a fake one ("60 days").
We don't ask you to take our word for it. Every batch is verified by an independent third-party lab using HPLC (high-performance liquid chromatography). The Certificate of Analysis is available for every lot — scan the QR on the bottle, or download it from the testing section above. The receipts exist because pet parents deserve them.
Stop immediately and call your vet. Reactions are rare, but they happen with any supplement, and they take priority over everything. Then please tell us — we keep records of every report so we can spot patterns, improve the product, and stay honest with the next pet parent.
