TB-500 is a synthetic 43-amino acid peptide designed to mimic the active region of Thymosin Beta-4 (Tβ4), a naturally occurring protein found in high concentrations throughout the human body including blood platelets, wound fluid, white blood cells, muscle tissues, and stem cells. This ubiquitous presence indicates its fundamental importance in cellular processes related to tissue maintenance and repair.

The peptide works primarily through regulating actin, a protein essential for cellular structure and movement, which enables cell migration to injury sites, tissue remodeling during healing, blood vessel formation (angiogenesis), and cellular differentiation and growth. Research indicates TB-500 also has anti-inflammatory effects, supports the migration of stem cells and other repair cells to damaged areas, and promotes the formation of new blood vessels crucial for delivering oxygen and nutrients to damaged tissues.

Animal studies have demonstrated TB-500's impressive potential across multiple tissue types: accelerated wound healing with better tissue architecture and reduced scarring; enhanced muscle healing through promoting satellite cell activation and reducing fibrosis; improved tendon and ligament healing with enhanced collagen organization and tensile strength; potential cardiac protection and support for heart muscle cell survival; and emerging neuroprotective effects with possible benefits in traumatic brain injury and stroke recovery models. The peptide is frequently studied alongside BPC-157 due to complementary mechanisms, with TB-500 focusing on cell migration and angiogenesis while BPC-157 emphasizes tissue protection and repair, and many research protocols use both for synergistic benefits.

Research protocols typically include a loading phase with higher frequency administration for 2-4 weeks to establish therapeutic levels, followed by a maintenance phase with reduced frequency for ongoing tissue health support. At Vitality Labz, our TB-500 10mg represents a commitment to research excellence with 99%+ purity verified by HPLC and mass spectrometry, proper synthesis using the validated 43-amino acid sequence, complete testing including endotoxin and sterility panels, and optimal packaging with complete Certificate of Analysis.

Animal research has generally found TB-500 well-tolerated with low incidence of adverse effects and minimal systemic toxicity, though it's important to note this compound has not been FDA-approved and is intended for research purposes only.
