About TB-4:

Thymosin Beta-4 is a peptide found naturally in nearly all human cells, where it plays a part in cell migration and the formation of new blood vessels. TB-4 is its synthetic form, produced for consistency and purity.

Because its mechanism is systemic rather than localized, it is frequently paired in protocols with peptides that act at the site of injury. Each vial is manufactured to pharmaceutical-grade standards, supplied lyophilized for stability, and verified for purity by an independent laboratory. A certificate of analysis is available on request.

Used in protocols for:

Your physician may include TB-4 in a treatment protocol related to:

  • Muscle, tendon and ligament recovery

  • Cell migration and angiogenesis support

  • Inflammatory response regulation

  • Post-injury recovery programs

Whether this peptide is appropriate for you, and at what dose and duration, is determined by your treating physician based on your individual evaluation.
