Overview
Description
A regenerative peptide researched for supporting tissue repair, cellular migration, and recovery. Often selected to support mobility, flexibility, and muscle recovery—especially in connective-tissue–focused protocols.
TB-500 is commonly referenced in research for improving how cells move, rebuild, and recover after stress, making it a strong option for athletic recovery and post-injury models.
Scientific Overview
TB-500 is a synthetic version of thymosin beta-4, a naturally occurring peptide involved in actin regulation—critical for cell structure and movement. Research explores its role in cellular migration, angiogenesis-related signaling, and tissue regeneration pathways in experimental models. Interest also includes inflammatory signaling modulation and recovery-focused outcomes in preclinical studies.

Frequently asked questions
Yes. Every batch of TB-500 10mg undergoes independent third-party testing using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS). The Certificate of Analysis is published and accessible from the product page.
TB-500 10mg sold by MHS Longevity is verified to 99%+ purity, with the result documented in each batch's Certificate of Analysis. Anything below that threshold is rejected before release.
The Certificate of Analysis for TB-500 10mg is available directly from the product page and on our Third-Party Test Results page. Each COA includes the batch identifier, test date, testing method, and verified purity percentage.
TB-500 10mg ships from our US-based facility with standard or expedited options. Orders over $150 qualify for free standard US shipping. All orders are packaged discreetly with documented handling protocols.
No. TB-500 10mg is supplied strictly for laboratory research purposes only. It is not approved by the FDA for human or veterinary use, and it is not intended to diagnose, treat, cure, or prevent any disease.
MHS Longevity is a veteran-owned operation focused on pharmaceutical-grade research compounds. We source from vetted manufacturers, batch-test independently with HPLC and Mass Spectrometry, and publish every Certificate of Analysis. Pricing is transparent and the testing process is documented end-to-end.
TB-500 and BPC-157 are both peptides studied in tissue-repair research, but they have different origins, sequences, and proposed mechanisms in the published literature. TB-500 is a synthetic fragment of thymosin β4 with actin-binding activity; BPC-157 is a 15-amino-acid fragment derived from a gastric protective protein. We stock both as separately tested compounds.
Not exactly. Thymosin β4 (TB4) is a 43-amino-acid endogenous protein. TB-500 is a synthetic peptide based on a fragment of TB4 that includes the actin-binding motif. Researchers studying full-length TB4 should use a full-length synthetic preparation; TB-500 is appropriate when the research design specifically calls for the fragment.
TB-500 is sent to an independent third-party laboratory for HPLC and Mass Spectrometry analysis before each batch is released. The lab's identifier and test date are published on the Certificate of Analysis for that batch.
Longer peptides accumulate more potential synthesis errors — truncated sequences, missed couplings, side-chain modifications. HPLC can flag many of these but cannot always resolve closely-eluting impurities. Mass Spectrometry directly measures whether the molecule matches the expected mass for the full sequence.

Research details — TB-500 10mg
TB-500 is a synthetic peptide based on a fragment of thymosin β4 (TB4), a 43-amino-acid actin-sequestering protein found across multiple tissues. The TB-500 fragment includes the actin-binding motif of the parent protein and has been used in over two decades of published tissue-repair research. This guide explains what TB-500 is, the research context, and how each batch is verified before release.
What is TB-500?
TB-500 is a synthetic peptide reproducing the actin-binding region of thymosin β4. The full parent protein is 43 amino acids; TB-500 is a shorter fragment centered on the LKKTETQ motif responsible for actin-monomer sequestration. It is supplied as a lyophilized white powder for laboratory reconstitution. The exact molecular weight and sequence as supplied are documented on each batch's Certificate of Analysis.
TB-500 is sold strictly for laboratory and research use. It is not approved by the FDA or any other regulatory body for human or veterinary use, and nothing in this guide constitutes guidance for human administration.
Research context
Published research on thymosin β4 and its fragments spans tissue-repair models, cardiac and dermal wound-healing studies, and inflammatory-modulation work. TB-500 as a synthetic peptide has been investigated in equine veterinary research and in a smaller body of mammalian preclinical work. Researchers should evaluate the underlying TB4 literature alongside the specific TB-500 fragment studies and consider replication status when designing experiments.
How TB-500 quality is verified
Every batch of MHS Longevity TB-500 is submitted to an independent third-party laboratory before release. Two complementary methods are used:
- HPLC separates components of the sample and measures the TB-500 peak as a percentage of total peak area. Anything below 99% is rejected.
- Mass Spectrometry confirms the molecule's identity. TB-500's longer length makes mass-confirmation particularly informative — it rules out truncated synthesis products that HPLC might not fully resolve.
What a TB-500 Certificate of Analysis shows
- Compound name and structural designation. TB-500, with the supplied amino-acid sequence and molecular formula documented for that batch.
- Batch identifier. The unique ID linking certificate to vial.
- Test date. When the analysis was performed.
- Method. HPLC, MS, or both, with column and mobile-phase notes.
- Verified purity %. The HPLC result. We require 99%+.
- Lab and signatures. The independent lab performing the analysis.
Storage and handling (research lab context)
Lyophilized TB-500 should be stored at -20°C or below for extended stability. Once reconstituted in bacteriostatic water, the solution is typically held at 2–8°C. Longer peptides like TB-500 benefit from minimized freeze–thaw cycling and protection from light and moisture. Standard aseptic technique applies during reconstitution.
Where to buy TB-500 10mg
The same eight questions apply whether you're buying TB-500 10mgfrom us or anywhere else. Vendors who can't answer any of them are worth a closer look.
Vendor evaluation checklist
1. Is the Certificate of Analysis public and downloadable?
A vendor unwilling to publish HPLC/MS results for the batch you're buying has nothing to verify their purity claim against.
2. Which testing method was used — HPLC, Mass Spectrometry, or both?
HPLC measures purity. Mass Spectrometry confirms the molecule's identity. Reputable batches go through both.
3. What's the verified purity percentage on the published COA?
Industry research standard is 99%+. Below that, you're paying for a compound diluted with synthesis byproducts.
4. Where does the product ship from?
US-based fulfillment generally means shorter handling times, customs-free delivery, and clearer return remedies.
5. Is the price published at a single list rate, or hidden behind tier locks?
Opaque pricing is a yellow flag. Transparent vendors quote the same number to every customer.
6. What's the free-shipping threshold, if any?
Compare the all-in cost (product + shipping + handling) — not just the headline price.
7. How is the product stored prior to shipment?
Lyophilized peptides degrade with temperature swings. Vendors should disclose temperature-controlled storage.
8. Is there a documented damage-claim and return policy?
Discreet shipping carries handling risk. A clear, written policy protects you when something goes wrong.
