VIP Peptides · Research Compound
Thymosin Beta-4 (TB4) is a naturally occurring 43-amino-acid peptide
studied in cell migration, actin regulation and tissue-repair pathways.
TB-500 is a related synthetic fragment; it is not the same molecule.
Product Information
Thymosin Beta-4 is a naturally occurring peptide found in many
tissues, including platelets and white blood cells. Research has
examined its role in actin regulation, cell migration and tissue
remodeling.
Laboratory and preclinical studies have explored pathways related
to angiogenesis, inflammation and wound repair. These findings do
not establish clinical benefits for a particular product or use.
TB4 and TB-500 should not be treated as interchangeable names.
TB-500 is commonly used to refer to a synthetic fragment, and
commercial naming can vary. Confirm the exact identity and
sequence against the product label and matching batch documents.

Research Areas
TB4 has been studied for its interaction with actin and its
potential role in cell movement. Laboratory findings do not
establish a clinical tissue-repair effect in people.
Preclinical studies have examined TB4 in skin, cardiac,
musculoskeletal and corneal injury models, including tissue
remodeling and scar-related pathways. Animal results do not
establish human outcomes.
Research has explored new blood-vessel formation and inflammatory
signaling in experimental settings. These proposed mechanisms are
not proof that TB4 or a related fragment treats injury or disease.
Evidence Overview
Most evidence described for tissue-repair pathways comes from cell
and animal research. Human clinical research is limited, and does
not establish broadly applicable effectiveness or a standardized
clinical use for research products.
TB4 and TB-500 may differ in sequence, structure and product identity.
FDA notes that products sold under the common name “TB-500” may not
have consistent chemical identity. Evidence or product information
for one form should not automatically be applied to the other.
Safety & Regulatory Status
Thymosin Beta-4 is not an FDA-approved treatment for the uses commonly
discussed in research or wellness settings. Human safety information
for research products and fragments may be limited.
For TB-500, FDA reports that it has not identified human exposure data
for drug products containing the fragment and notes potential
immunogenicity concerns related to aggregation and peptide-related
impurities. These concerns apply to products containing TB-500; they
should not be read as proof that every TB4 product has the same
composition.
Product quality, identity and purity can vary between suppliers.
A certificate of analysis, if available, should match the specific
batch and identify the tested material.
