Vet guidance

Talk to your vet first. They know things about your pet that we never could β€” 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?

TB-500 is a synthetic peptide fragment of Thymosin Beta-4 β€” a protein naturally produced in nearly every cell in the body. It's composed of a specific amino acid sequence that mimics the bioactive region of the full protein.

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.

Research in this area continues to evolve. What we provide is the peptide in its pure, well-characterized form β€” fully documented for your research protocol.

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 β€” not a sales pitch from us.

What's Inside

01 TB-500 (Thymosin Beta-4 Fragment) TB-500 stands for Thymosin Beta-4 Fragment. This row identifies the active research peptide in the vial, commonly studied for movement, flexibility, and recovery-related pathways.
5 mg
02 Form Lyophilized means freeze-dried. This helps keep the peptide stable in powder form until it is ready to be prepared.
Lyophilized Powder
03 Purity (HPLC) HPLC stands for High-Performance Liquid Chromatography. This test helps verify the peptide’s purity and confirms it meets a high-quality standard.
β‰₯ 99%
04 Packaging The peptide is packaged in a sealed vial to help protect the powder, maintain cleanliness, and keep the product secure until opened.
Sterile Sealed Vial
For research use only. Not for human or animal consumption. Manufactured under cGMP-aligned facility. Every vial is individually packaged, sealed, and accompanied by lot documentation.
