TB4 Price Comparison
Also referred to as: Thymosin Beta-4
UK supplier comparison
Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

Suppliers are being onboarded. This comparison will populate as listings go live. Everything below — the research profile, molecular facts and guides — is available now.
For in-vitro laboratory research only
TB4 is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.
Research profile
About TB4 in the lab
Thymosin beta-4 is one of the most abundant intracellular peptides in mammals. The full-length protein differs from 'TB-500' fragments, so confirm on the certificate of analysis which form a listing contains.
Proposed mechanism
Binds monomeric G-actin, regulating the pool available for polymerisation; extracellular Tβ4 is studied for effects on cell migration, angiogenesis and inflammation.
Typical research themes
- Actin sequestration
- Cell migration
- Full-length vs fragment
This profile is a short, general summary of publicly discussed science. It is not exhaustive, not peer-reviewed by PeptideCompare, and is not medical advice. PeptideCompare provides no dosing, protocol or usage guidance — nothing here is for human or veterinary use.
