Thymosin Beta-4

How It Works

Thymosin Beta-4 sequesters G-actin (monomeric actin), regulating actin polymerization which is essential for cell migration, proliferation, and differentiation. It promotes angiogenesis, reduces inflammation through NF-κB modulation, and activates cardiac progenitor cells. TB-500 is a synthetic fragment of Thymosin Beta-4 containing the active region, but full-length Tβ4 provides additional biological activities.

Key Research Findings

• Promotes tissue repair across muscle, tendons, ligaments, skin, and cardiac tissue
• Cardioprotective properties — activates cardiac progenitor cells after ischemia
• Reduces fibrosis and scar formation in multiple tissue types
• Currently in clinical trials for wound healing and cardiac repair applications

Reconstitution Guide

Follow these steps to properly reconstitute Thymosin Beta-4 for research use:

• Step 1: Swab the tops of both the peptide vial and bacteriostatic water vial with alcohol.
• Step 2: Draw your desired amount of BAC water (commonly 1–2 mL) into an insulin syringe.
• Step 3: Inject the water slowly into the peptide vial, aiming at the glass wall — not directly onto the powder.
• Step 4: Swirl the vial gently until fully dissolved — never shake.
• Step 5: Refrigerate at 36–46°F (2–8°C). Use within 4–6 weeks.

Use the dosing calculator to calculate your exact concentration (mcg per unit) and how many units to draw on your syringe.
