FAQ
Asked often, answered straight.
Quality & testing
Are your peptides third-party tested?
Yes. Every batch is verified by an independent laboratory for identity and purity, and every vial carries a QR code that opens the certificate of analysis for its lot.
Where are your products made?
In the United States, in a certified laboratory. American made is not a slogan for us — it is the supply chain.
Are these products FDA approved?
No. None of our products have been evaluated or approved by the FDA, and they are not intended to diagnose, treat, cure, or prevent any disease. We make structure and function statements only.
About the peptides
What is BPC-157?
BPC-157 is a 15-amino-acid peptide sequence modeled on a protein found in gastric juice. Researchers have studied it in animal models for its relationship to the body's natural recovery and maintenance processes.
What is TB-500?
TB-500 is a synthetic version of the active region of thymosin beta-4, a naturally occurring protein studied for its role in cellular migration and tissue maintenance.
Why combine BPC-157 and TB-500?
The two peptides are studied for different but complementary pathways, which is why they so often appear together in the research. The blend simplifies handling for owners following the literature with their veterinarian.
What is GHK-Cu?
GHK-Cu is a copper-binding tripeptide found naturally in the body. It has been studied for decades for its role in skin and connective-tissue maintenance.
What is in Glow?
Each 70 mg vial contains BPC-157 10 mg, GHK-Cu 50 mg, and TB-500 10 mg. The certificate of analysis for each lot verifies identity and purity of every component.
What is in Klow?
Each 80 mg vial contains BPC-157 10 mg, GHK-Cu 50 mg, TB-500 10 mg, and KPV 10 mg. The certificate of analysis for each lot verifies identity and purity of every component.

Working with your vet
Do I need a veterinarian involved?
Yes, we always recommend it. Your veterinarian knows your animal and can help you read the research and decide what fits. We never provide dosing or medical guidance.
Do you publish protocols or usage guidance?
No. We don't publish protocols, dosages, or usage regimens of any kind. Those decisions belong to a licensed veterinarian who knows your animal. For community research reports, we like The Pet Peptide Ledger: A community-run research library we read ourselves.
