TB-500 is a thymosin beta-4–derived peptide fragment often used in recovery-focused protocols for its role in cell migration, tissue remodeling, and vascular support. It’s typically chosen when the goal is whole-body soft tissue recovery—especially when multiple areas are strained or training volume is high.
TB-500 is associated with pathways involved in:
Commonly referenced injectable protocols:
(Protocols vary by goal, injury severity, and clinician preference.)
Important: TB-500 is not FDA-approved for human therapeutic use and is often sold as research-use-only. It is also prohibited by WADA for tested athletes.
If you’re combining peptides, many protocols pair:
Only stack under medical supervision—stacking increases variables (dose, timing, response), and injection safety and sourcing quality matter most.
TB-500 is a synthetic peptide commonly described in research contexts as a fragment of Thymosin Beta-4 (Tβ4). In preclinical literature, Thymosin Beta-4–related peptides have been explored for their association with wound-healing models, angiogenic signaling, inflammatory mediator modulation, and extracellular matrix organization. TB-500 is used as a research tool to study these pathway readouts in vitro and in vivo (animal-model) settings.
Thymosin Beta-4–related peptides are known in research for binding monomeric actin (G-actin) and participating in actin-sequestration dynamics, which can influence processes such as cell motility and structural remodeling. In controlled research models, these pathways are evaluated through cell migration assays, endothelial signaling readouts, and markers associated with inflammation and extracellular matrix turnover.
Supplied as a lyophilized powder. Handle using appropriate laboratory PPE and aseptic technique where applicable, in accordance with your lab’s protocols.
