How It Works
1. Concentration
Divide vial amount (mcg) by water volume (mL) to get concentration (mcg/mL).
2. Volume needed
Divide desired dose by concentration to get injection volume in mL.
3. Syringe units
Multiply mL × 100 to get U-100 syringe units (IU).
Example
- 5 mg vial + 2 mL water = 2.5 mg/mL
- Want 250 mcg (0.25 mg)?
- 0.25 ÷ 2.5 = 0.1 mL
- 0.1 mL = 10 units on a U-100 syringe

Why this research peptide
Thymosin Beta-4 fragment
Synthetic version of a peptide present in all human cells, studied in tissue-repair research.
Actin regulation
Main mechanism studied in vitro: binding to G-actin, involved in cell structure and migration.
Studied systemic profile
Unlike locally-acting peptides, TB-500 is studied for its body-wide distribution in research models.
Verified purity
HPLC + mass spectrometry analysis by an independent laboratory, certificate included with every batch.
Long-term storage
Lyophilised form stable for up to 24 months at -20°C for extended storage in the laboratory.

What is TB-500?
TB-500 is a synthetic fragment of Thymosin Beta-4 (Tβ4), a peptide naturally present in all human cells, at particularly high concentration in platelets and wound fluid. It is studied in the research literature for its role in cell migration, angiogenesis and the inflammatory response. Used as a research reagent in the laboratory, frequently paired with BPC-157 in in vitro protocols. Lyophilised product supplied with an independent certificate of analysis — not for human consumption.
Storage & handling
Product intended exclusively for scientific research in the laboratory. Keep in its original packaging until use.
