TB-500

Thymosin Beta-4 Fragment

Regulates actin — the protein that forms the cellular cytoskeleton. Promotes cell migration, angiogenesis, and differentiation. Has documented heart muscle repair effects in animal models.

Dose

Loading phase: 4–8mg per week (split into 2 injections) for 4–6 weeks

Cycle

Loading 4–6 weeks, then maintenance

Timing

Twice weekly injections (e

Benefits & Effects

  • Systemic tissue repair (works throughout the body)
  • Flexibility improvement
  • Reduced inflammation and scar tissue
  • Heart muscle recovery
  • Faster return-to-activity after injury

Reconstitution & Dosing

Reconstitution

10mg vial + 3mL BAC water = 3,333mcg/mL. Draw 30 units for 1mg, 60 units for 2mg.

Dose

Loading phase: 4–8mg per week (split into 2 injections) for 4–6 weeks. Maintenance: 2mg per week indefinitely.

Cycle Length

Loading 4–6 weeks, then maintenance. Can run indefinitely at maintenance dose.

Timing

Twice weekly injections (e.g., Mon/Thu). SubQ or IM, rotation of sites.
