What it supports

Built for your research

A clear look at what this compound is here to support — in plain language, no hype.

Tissue-repair research

Studied for its relationship to repair-cell migration and tissue remodeling.

Cardiac-tissue context

The parent compound is studied in ischemic cardiac-dysfunction models.

Ocular-surface research

Phase II work explores a thymosin beta-4 formulation in dry-eye models.

Preclinical and early clinical

Evidence spans preclinical models and limited early-phase clinical work.

How it's thought to work

The science, plainly

Emerging science suggests how this compound relates to your body's own pathways. We share it for context — not as a promise.

01

Thymosin beta-4 fragment

Modeled on a fragment of thymosin beta-4, an actin-binding protein involved in tissue-stress response.

02

Cell-migration associations

Emerging science suggests a relationship to how repair cells move to sites of tissue stress.

03

Broad tissue-repair focus

Studied across cardiac, ocular, and musculoskeletal models.

Selected research

Emerging science in this area

A few peer-reviewed studies that explore the compound this product is built around. We share these for context and curiosity — not as claims about what this product will do for you.

Thymosin beta 4 ophthalmic solution for dry eye: a randomized, placebo-controlled Phase II clinical trialClinical Ophthalmology, 2015. · 2015A randomized, placebo-controlled Phase II trial suggests topical thymosin beta-4 may improve ocular discomfort and corneal staining in dry-eye patients, with no reported adverse events; larger confirmatory trials are still needed.

Recombinant human thymosin beta 4 improves ischemic cardiac dysfunction in mice and STEMI patients after reperfusionCardiovascular Research, 2025. · 2025Emerging research combining preclinical models and a randomized placebo-controlled trial in STEMI patients suggests recombinant thymosin beta-4 may help limit cardiac injury after reperfusion when given early, though the overall between-group difference was not statistically significant.

Good questions

What people ask first

How is TB-500 different from BPC-157?

Both are studied in tissue-repair models, but TB-500 is modeled on a thymosin beta-4 fragment while BPC-157 is a gastric-derived peptide studied for gut-barrier and endothelial signaling. We'll help you choose based on your research application.

Is TB-500 well studied in humans?

Evidence is mixed: preclinical data plus a phase II dry-eye trial and an early cardiac-reperfusion trial. We'll frame what's established versus emerging in the chat.

Can I talk to a specialist before buying?

Yes — optional, never required. Every product lists its price and ships through a secure checkout, so you can buy directly. If you want help choosing or matching a compound to your research application, start a private chat with a research specialist.

How is pricing handled?

Every product lists its price on the site. Add to cart and check out securely by card — volume discounts apply automatically, and your CVV is purged within 24 hours. No surprise charges, no recurring billing.

What if it isn't right for my research?

If a product isn't a fit for your research application, we'll say so and point you to what is. You're never committed by starting a chat, and every order is sold for laboratory and analytical research use only.
