Research Peptide
TB-500 10mg Research Peptide
Write a ReviewTB-500 (also written without a hyphen, TB500), as specified for this listing, is synthetic full-length Thymosin Beta-4, a naturally occurring 43-amino-acid peptide involved in actin regulation and cell migration. The name TB-500 is also used elsewhere for a much shorter acetylated fragment, so the measured molecular mass on the lot COA is what confirms the material. It is supplied here as a lyophilized powder, independently tested for identity and purity, for laboratory research exclusively.

Purity Specification
99%+ Purity, Independently Verified
Every batch we release is required to meet a minimum purity specification of 99% by HPLC before it ships. Purity is not a marketing claim here — it’s a published, batch-specific result from an independent, third-party analytical laboratory, available below for the current batch.

Testing Methodology
How Each Batch Is Verified
- 1
Independent Lab Analysis
Every batch is sent to a third-party analytical laboratory, unaffiliated with production, for identity and purity testing.
- 2
HPLC Purity Analysis
High-performance liquid chromatography (HPLC) is used to evaluate chromatographic purity by separating and measuring components present in the analyzed sample.
- 3
Certificate of Analysis
Results are published as a batch-specific COA, linked from this page and searchable in our COA archive.
- 4
Batch Traceability
Every vial is labeled with a batch number that maps directly to its published test results.
Purity ≠ Identity
Purity and molecular identity are related but distinct analytical characteristics. Review the applicable laboratory report to understand which attributes were tested.

Handling This Research Reagent
Store lyophilized at -20°C; refrigerate after reconstitution
As with any lyophilized peptide reagent, minimize freeze-thaw cycles and avoid prolonged exposure to light, heat, or humidity before use. These are general laboratory-reagent storage practices, not instructions for administration of any kind.

Common Questions
TB-500 10mg FAQ
How can I verify the testing for this TB-500 batch?
Testing documentation is published by lot when available. Use the Current Batch COA section on this page or the Full Spec COA database to review the analytical results and original laboratory documentation associated with the applicable batch.
What does peptide purity mean?
Purity describes the proportion of the analyzed sample represented by the target chromatographic component under the stated analytical method. Purity should not be treated as interchangeable with molecular identity, quantity, sterility, or other quality attributes.
What is TB-500?
TB-500, as specified for this listing, is synthetic full-length Thymosin Beta-4, a 43-amino-acid peptide that occurs naturally in nearly all human and animal cells. It’s studied in the context of cell migration, tissue formation, and related recovery research. The name TB-500 is also used elsewhere for a much shorter acetylated fragment, so the molecular mass on the lot COA is what confirms the material.
How should TB-500 be stored?
Keep the lyophilized powder frozen until use. After reconstitution, refrigerate the solution and use it within your lab protocol’s stated window.
How is purity verified for this product?
Every batch is independently tested by a third-party lab for identity and purity. The current batch’s COA is published above.
