TB-500 for Sale: Thymosin Beta-4 Research Peptide Prices and Buying Guide

Searching for TB-500 for sale brings up hundreds of sellers, but very few explain what they are actually selling. “TB-500” is used for more than one material, so knowing the difference, and knowing what you pay per vial, is the fastest way to avoid a bad batch. Here is what you need to know before you order.

What is TB-500?

TB-500 is the market name for synthetic peptides based on thymosin beta-4 (Tβ4). Thymosin beta-4 is a 43-amino-acid protein found in most human cells, where its best-known role is binding actin, a building block of the cell’s internal skeleton.

• Reference protein: thymosin beta-4, 43 amino acids, about 4.9 kDa (gene TMSB4X)
• Form: lyophilised (freeze-dried) powder
• Vial sizes: 5mg and 10mg

Two materials sold as “TB-500”

This is the point most sellers skip. In the research-peptide market, “TB-500” is used for:

1. Synthetic full-length thymosin beta-4 (43 amino acids), and
2. A short seven-amino-acid fragment of it, Ac-LKKTETQ (residues 17–23).

Both are legitimate research materials, but they are not interchangeable. Always check the certificate of analysis for your batch to confirm which form you are receiving. If a seller cannot tell you, look elsewhere.

TB-500 wholesale prices

Prices are per box of 10 vials in US dollars. The minimum order is 5 boxes per item, with lower prices from 20 and 50 boxes.

Shipping is added on your invoice. See live prices on the TB-500 product page.

TB-500 in laboratory research

Thymosin beta-4 and peptides derived from it are studied mainly in cell and animal models, including work on actin dynamics and cell migration. Results from those models cannot be taken as evidence of safety or effect in people. TB-500 is not an approved medicine in the US, UK, EU or Canada, and thymosin beta-4 and TB-500 are prohibited in competitive sport by the World Anti-Doping Agency. Our TB-500 is sold for laboratory research use only.

TB-500 blends and related products

TB-500 is frequently studied alongside BPC-157, so we also supply ready-made combinations. Buying a blend means one vial instead of two:

Also see BPC-157 on its own. Note that Thymosin Alpha-1 shares the “thymosin” name but is an unrelated peptide.

Frequently asked questions

What is the price of TB-500?

At the time of writing, TB-500 costs $77 per box of 10 x 5mg vials and $145 per box of 10 x 10mg vials, with lower prices from 20 and 50 boxes.

Is TB-500 the same as thymosin beta-4?

Not always. The name covers both synthetic full-length thymosin beta-4 and a seven-amino-acid fragment (Ac-LKKTETQ). Check the certificate for your batch.

Can I order TB-500 and BPC-157 together?

Yes. Add both to the same order, or choose the BPC-157 & TB-500 Blend if you want them in one vial.

How should TB-500 be stored?

Keep vials sealed, dry, cold and away from light. See how to store research peptides properly.
