TB-500 — A Thymosin β4 Fragment
TB-500 is a short synthetic fragment related to Thymosin β4. It is discussed in tissue-repair and cell-movement research, but evidence for TB-500 itself is limited and should not be confused with studies of the full Thymosin β4 protein. Aeternum Life supplies a clearly identified, batch-tested research material made to Japan quality standards and shipped from Japan with its own COA. It is not an approved medicine.

COA records appear by product and batch when a matching record is published.
What is TB-500?
TB-500 commonly refers to a synthetic seven-amino-acid fragment related to Thymosin β4, with the sequence Ac-LKKTETQ. Thymosin β4 is a much larger natural protein, so the two names are not interchangeable.
The fragment is discussed in research involving actin, cell movement and tissue-repair models. However, evidence for TB-500 itself is limited, and the product has no approved human use. Aeternum Life verifies identity and purity by batch and supplies a matching Certificate of Analysis with every order.
Research directions
The clearest way to understand TB-500 research is to separate questions studied on the fragment from claims borrowed from the full Thymosin β4 protein.
Because “TB-500” can refer to different forms, researchers need to confirm the exact molecule and batch before drawing conclusions.
In-vitro work asks how the fragment interacts with actin-related cell movement. A lab signal is not a proven result in people.
Wound and repair models are discussed, but FDA reviewers found the available evidence inadequate to support wound-healing effectiveness.
A major reading check: was the study performed on TB-500, or on full-length Thymosin β4? The answer changes what can be concluded.
No reliable human exposure data were identified in the FDA review, so human safety and outcomes remain unknown.
Identity testing, HPLC purity and a matching lot number help researchers know what material they are actually evaluating.

Frequently asked questions
What is TB-500 known for?
It is discussed in cell-movement and tissue-repair research. Evidence for the TB-500 fragment itself is limited, and there are no established human recovery benefits.
How is TB-500 different from BPC-157?
They are different peptide sequences with different research histories. Neither is an approved medicine, and we do not provide dosing, reconstitution or administration guidance.
Is TB-500 for human use?
No. Aeternum Life supplies TB-500 strictly as a research-grade material for laboratory research. It is not sold for human or veterinary consumption.
Is a COA available for TB-500?
Published COA records are available by product and batch when a matching record exists. Laboratory and verification details appear only when stated in that record.
