TB-500: A Research Overview
All information here is for laboratory and educational research only. No compound referenced is approved for human or veterinary use, and nothing here is medical advice.
TB-500 is the name commonly used in research and biohacker communities for a synthetic fragment related to Thymosin Beta-4, a naturally occurring protein studied for its role in cell movement and tissue repair. It is frequently discussed alongside BPC-157 in recovery communities. All information here is for laboratory and educational research only. No compound referenced is approved for human or veterinary use, and nothing here is medical advice. This page summarizes what the published research shows, and where the evidence is strong versus where it is still early.
What TB-500 Is
TB-500 refers to a synthetic peptide related to Thymosin Beta-4, a small protein involved in regulating actin, a structural protein that cells use to move and change shape. Thymosin Beta-4 itself has a substantial published research history; TB-500 specifically, as sold in research contexts, has a much smaller and more recent body of directly relevant study. Any TB-500 material supplied by BioRegen is handled strictly as a lab chemical for laboratory and educational research, not for use in people or animals.
What the Research Shows
Controlled human clinical trial data for TB-500 is limited; the published evidence base is predominantly preclinical. A 2026 scoping review mapping the literature on Thymosin Beta-4 and TB-500 in tissue healing, regeneration, and musculoskeletal repair found the evidence weighted toward mixed and in-vitro study designs, with most of the available research examining Thymosin Beta-4 rather than TB-500 specifically, and direct TB-500 evidence limited to a single included study. Animal and cell research has studied TB-500 and Thymosin Beta-4 in cell migration, actin regulation, tissue regeneration, and wound-healing models, including reported effects on collagen deposition and new blood-vessel formation in preclinical wound models. Human evidence in that same review was concentrated in cornea and skin/soft-tissue settings for Thymosin Beta-4, not TB-500 directly.
Community Discussion and Its Limits
TB-500 is frequently discussed alongside BPC-157 in recovery and animal-research communities, often as a pairing believed to have complementary mechanisms. That discussion is unverified anecdotal commentary, not controlled findings, and not a BioRegen claim. As with BPC-157, the gap between an active, consistent preclinical literature and a very thin direct human evidence base is exactly the kind of situation that tends to generate active community discussion, and readers should weigh that discussion accordingly.
Regulatory Status and Handling
TB-500 is not approved by the FDA for human use, and it is prohibited in sport by the World Anti-Doping Agency (WADA). BioRegen supplies TB-500 reference material strictly for laboratory and educational research, not for human use. As a lab chemical, it is typically supplied as a lyophilized (freeze-dried) powder that should be kept cold and reconstituted only immediately before use in a laboratory setting.

Frequently Asked Questions
Is TB-500 the same thing as Thymosin Beta-4?
They are closely related but not identical in the research literature: Thymosin Beta-4 is the naturally occurring protein with the larger published research history, while TB-500 is the name used for the synthetic research peptide, and current evidence specific to TB-500 itself is much more limited than the broader Thymosin Beta-4 literature.
Does TB-500 have human clinical trial data?
Controlled human trial data is very limited. A 2026 scoping review of the combined literature found direct TB-500 evidence limited to a single study, with most available research examining Thymosin Beta-4 in preclinical or mixed designs instead.
Is TB-500 approved for any use in people?
No. TB-500 is not FDA-approved for human use and is prohibited in sport by WADA. The material BioRegen supplies is a lab chemical intended strictly for laboratory and educational research.
