What it is
TB-500 is a lab-made peptide based on the active region of thymosin beta-4, a protein found in most cells that helps with cell movement and tissue repair.
What the research shows
Research on thymosin beta-4 and TB-500 comes mostly from animal and lab studies on wound healing and tissue repair. Human research is very limited.
How it's used
TB-500 is commonly supplied as a 5.0 mL vial at 3.0 mg/mL. A typical dose is 600 mcg (20 units), injected under the skin, once daily. Your prescriber sets your exact dose and schedule.
