TB-500 is a synthetic version of Thymosin Beta-4, a naturally occurring peptide involved in cell migration and tissue repair. It is widely studied alongside BPC-157 in recovery research.

What is TB-500?
TB-500 is a synthetic fragment of thymosin beta-4, a naturally occurring protein involved in cell migration and tissue repair. It is not the full protein but the active region of it, which is why it appears in research as a practical laboratory material rather than a difficult-to-produce full-length molecule.
Thymosin beta-4 is one of the most abundant proteins in many cell types and is heavily involved in actin regulation, the protein scaffolding that lets cells change shape and move.
TB-500 research applications
Published research concentrates on soft tissue repair, cell migration, and actin sequestration. It is studied in tendon, ligament and muscle repair models, and frequently alongside BPC-157 on the reasoning that the two mechanisms address different stages of the same process.
The same caveat applies as across this category: the work is predominantly preclinical, and rodent musculoskeletal findings have a mixed record of transferring to human outcomes.
How TB-500 works
The core mechanism studied is actin binding. Actin is the structural protein that allows cells to migrate, and repair depends heavily on the right cells arriving at a damaged site and organising themselves once there. By influencing actin availability, thymosin beta-4 fragments appear to affect that migration process.
Secondary research areas include angiogenesis and inflammatory modulation, though these are less well characterised than the actin work.
TB-500 vs BPC-157
| Property | TB-500 | BPC-157 |
|---|---|---|
| Origin | Thymosin beta-4 fragment | Gastric protein fragment |
| Primary mechanism studied | Cell migration, actin regulation | Angiogenesis, vascularisation |
| Strongest research area | Soft tissue repair | Tendon repair, gut lining |
| Evidence type | Mostly preclinical | Mostly preclinical, larger volume |
Both are supplied together, with GHK-Cu, in the GLOW 70 blend, and with KPV added as well in KLOW 80.
TB-500 reconstitution and handling
Supplied lyophilized. Reconstitute with bacteriostatic water, adding the diluent slowly against the vial wall and allowing the powder to dissolve undisturbed. Do not shake. Bacteriostatic water is stocked separately. The TB-500 calculator turns vial strength and water volume into a concentration.
TB-500 storage and stability
Store sealed lyophilized vials at minus 20 degrees Celsius, protected from light. Reconstituted material requires refrigeration and a shorter usable window. Do not freeze and thaw repeatedly.
TB-500 price
TB-500 10mg is $74.99 per vial, which works out to $7.50 per mg. Ordering more than one vial lowers the price of every vial in the order. The table shows the TB-500 price per vial and per mg for every size. That TB-500 cost is the price per vial before shipping.

Where to buy TB-500 in the US
Searching for where to buy TB-500 peptide? The best place to buy TB-500 is a supplier that publishes its testing first. A vial is only worth what its testing is worth, so five checks separate a reliable US source from a reseller. This is how Healio meets each one.
- A certificate of analysis for the exact batch. The TB-500 report for batch HEALIO-TB500-2612 is published before you order, not emailed after you have paid.
- Testing by a lab that is not the seller. The report comes from Quantum Life Sciences in Portland, Maine, an independent laboratory, and carries its own certificate number.
- Identity as well as purity. HPLC measures how pure the powder is. Mass spectrometry (ESI-MS) confirms that it is TB-500 in the first place. A report with only one of the two is half a report.
- A lot number you can trace. The lot number on your vial ties to its own report, so you can check the document against the product in your hands.
- US dispatch and plain terms. Orders ship from the United States, and the shipping and returns policy is public before you buy.

TB-500 lab results
The current TB-500 batch was tested on 23 June 2026 by Quantum Life Sciences. The certificate covers the 10 mg vial. Purity is measured by HPLC and identity is confirmed by mass spectrometry. The summary below is taken from the certificate of analysis. Reading the TB-500 COA takes a minute: purity by HPLC, identity by mass spectrometry and endotoxins are in the first rows.
| Batch | HEALIO-TB500-2612 |
|---|---|
| Lot number | TB500-260623-12 |
| Purity (HPLC) | 99.1% (specification 98.0% or higher) |
| Identity (ESI-MS) | Confirmed, conforms to the reference standard |
| Mass found | 10.06 mg (labeled 10 mg) |
| Endotoxins (LAL) | Under 0.5 EU/mg (limit 5 EU/mg) |
TB-500 reviews: is Healio a legit TB-500 source?
Searching for TB-500 reviews, or asking whether Healio is a legit TB-500 source? The useful evidence is what you can check yourself, because reviews only help if you can check them.
- Match the lot number on your vial to the TB-500 certificate of analysis.
- Look up the testing laboratory named on the certificate and confirm it is not Healio.
- Read how the content on this site is written and checked on the editorial standards page.
- If a seller will not publish a batch report for the product you are buying, treat that as your answer.
