Product Description
TB-500 (Thymosin Beta-4 fragment) is a synthetic peptide derived from the N-terminal sequence of human thymosin beta-4. This 43-amino acid peptide is naturally present in virtually all human cells and tissues, particularly in tissue-remodeling and tissue-adaptation contexts. TB-500 has been extensively researched for its role in supporting tissue repair, adaptation, and cellular resilience.
Expert Insight
“TB-500's endogenous origin and ubiquitous tissue distribution make it a uniquely valuable research compound. As a naturally occurring peptide, it offers researchers a physiologically relevant model for investigating tissue adaptation, cellular protection, and repair mechanisms.”

Research Literature — TB-500
The following is a summary of published research literature. This information is provided for educational reference only and does not constitute medical advice or research amount guidance.
Research Amounts in Literature
In published studies, researchers have administered Thymosin Beta-4 at doses of 2–10 mg per administration in preclinical models. Research protocols commonly reference a loading phase of 5–10 mg followed by maintenance doses of 2–5 mg.
Frequency Protocols in Research
Researchers studying TB-500 have commonly used twice-weekly administration protocols during loading phases (2–4 weeks), transitioning to weekly or biweekly maintenance administrations.
Reconstitution Concentrations in Research
Published literature reports reconstitution of 5–10 mg vials in 2–3 mL bacteriostatic water, yielding concentrations of 1.7–5 mg/mL. Using 2 mL for a 10 mg vial (5 mg/mL) is the most commonly referenced standard.
Typical Syringe Ranges in Research
At common research concentrations (e.g., 5 mg/mL), typical administration volumes observed range from 20–100 units (0.2–1.0 mL) on a standard research syringe.
