Description
TB-500 10mg from Polaris Peptides is a lyophilised research peptide with over 99% purity confirmed by HPLC-MS. TB-500 is a synthetic thymosin beta-4 peptide (also known as Thymosin Beta-4 fragment), supplied vacuum-sealed and sold strictly for laboratory research.
At $70.00 this vial works out to $7.00 per milligram.
What Is TB-500 10mg?
TB-500 is a synthetic peptide based on thymosin beta-4 (Tβ4), a 43-amino-acid protein found in almost every human and animal cell. Tβ4’s main job is binding G-actin, the building block of the cell’s internal skeleton, which controls how cells change shape and move.
Because cell migration is central to wound closure, Tβ4 and TB-500 have been studied in models of skin, corneal, heart and muscle injury. The research name ‘TB-500’ is used widely in the peptide field for the synthetic material built around Tβ4’s active actin-binding region.

TB-500 Research Areas
Published studies on TB-500 cover several areas. The list below summarises the main ones so you can see where it fits your work.
- Actin regulation: how sequestering G-actin affects cell motility and structure.
- Wound closure: keratinocyte and endothelial cell migration in skin and corneal models.
- Cardiac repair models: published Tβ4 work on heart tissue after injury.
- Inflammation: modulation of inflammatory signalling in damaged tissue.
- Hair follicle biology: Tβ4’s role in follicle stem cell activity.
Storing and Handling TB-500 10mg
Store unopened vials at −20 °C, where the dry powder stays stable for long periods. Before reconstitution, let the vial reach room temperature to stop condensation forming inside. Add bacteriostatic water or another lab-grade solvent slowly down the side of the vial and swirl gently rather than shaking. Once reconstituted, keep it at 2–8 °C and complete your work within 28 days.
Why Order TB-500 From Polaris Peptides
Every batch of TB-500 we sell is checked by HPLC-MS for identity and purity before it is listed. Vials are vacuum-sealed to keep moisture out and labelled with the exact amount. If you are comparing suppliers, ask for the batch analysis and check it against the label. That is the standard we hold ourselves to.
How TB-500 10mg Is Tested
We use two methods together. High-performance liquid chromatography (HPLC) separates the contents of a sample so we can see how much of it is the target compound and how much is anything else, such as truncated sequences or leftover synthesis reagents. Mass spectrometry (MS) then weighs the molecules, which confirms that the main peak really is TB-500 and not a look-alike. A result above 99% on both counts is what earns a batch a place in our catalogue. Lots that fall short are not sold.

TB-500 10mg FAQ
Is TB-500 the same as thymosin beta-4?
TB-500 is the research name for synthetic material based on thymosin beta-4. Thymosin beta-4 itself is the full 43-amino-acid natural protein.
What is TB-500 usually studied with?
BPC-157 is the most common partner, and both appear in our GLOW and KLOW blends.
What purity is TB-500 10mg?
Over 99%, confirmed by HPLC-MS on every batch.
How should TB-500 be stored?
Dry powder at −20 °C. After reconstitution, 2–8 °C, used within 28 days.
Is TB-500 10mg for human use?
No. It is sold for laboratory and in-vitro research only. It is not a drug, food or cosmetic and is not for human or veterinary use.
