BRIEF OVERVIEW

TB-500 is a synthetic version of a naturally occurring peptide fragment derived from Thymosin Beta-4. It is primarily known for its role in cell migration, tissue repair, and regeneration. One of its key mechanisms of action is the regulation of actin, a protein essential for cell structure and movement. By promoting actin binding and cellular migration, TB-500 helps facilitate the repair of damaged tissues including muscles, tendons, ligaments, and skin. Unlike the full Thymosin Beta-4 molecule, TB-500 is a smaller fragment designed for enhanced systemic distribution, allowing it to travel more easily throughout the body and target multiple areas of injury. Research and clinical interest have highlighted its potential to reduce inflammation, promote angiogenesis, and accelerate healing, making it a popular option in regenerative and performance-based protocols.

A Real Prescription — Not a Research Peptide

Compounded TB-500 from Regen Doctors is a legitimate prescription medication. It is prepared by a licensed compounding pharmacy in compliance with applicable federal and state laws, and it is only dispensed after a licensed provider reviews your medical questionnaire and approves your prescription.

That is very different from the “research peptides” sold online and labeled “not for human use.” Those products come with no prescription, no provider oversight, and no reliable way to know what is actually inside the vial.

Enhanced flexibility and range of motion

Reduction in inflammation

Support for tendon and ligament healing
