TB-500

Repair & Recovery Injectable

TB-500 is a synthetic fragment of the naturally occurring protein Thymosin Beta-4. It promotes cellular migration to injured tissue — directing reparative cells where they're needed, forming new blood vessels, and rebuilding muscle fibers from the inside out. Often paired with BPC-157 for deep, layered tissue recovery.

Best for: Deep tissue injury, chronic muscular pain, connective tissue recovery, post-trauma rebuild.

The questions, answered.

  • Stimulates cell migration: directs stem and reparative cells to injury sites.
  • Supports muscle fiber regeneration: particularly useful after deep muscular strain or surgery.
  • Improves flexibility and range of motion through connective tissue remodeling.
  • Reduces inflammation at sites of chronic injury.
  • Cardioprotective potential: emerging research suggests benefit for cardiac tissue.
  • Synergistic with BPC-157 for complex or stubborn injuries.
  • Actin sequestration: regulates the actin cytoskeleton, which controls cell shape and movement.
  • Stem-cell recruitment: draws progenitor cells from bone marrow to injury sites.
  • Angiogenesis support: new capillaries form to nourish healing tissue.
  • Anti-inflammatory signaling: downregulates inflammatory mediators at the injury site.
  • Weeks 1–2: Mild softening of chronic tension; injection sites typically painless after first dose.
  • Weeks 4–6: Notable improvement in flexibility, recovery between workouts, and pain at chronic sites.
  • Weeks 8–12: Functional gains hold; many clients consolidate with a maintenance phase.
  • Injection-site discomfort: typically mild and short-lived.
  • Transient fatigue or 'heavy' muscles: as the repair process activates.
  • Flu-like sensation: rare, usually only with initial loading doses.
  • Loading then maintenance dosing: common protocols front-load the first weeks.
  • Combine with rest and physical therapy — the peptide accelerates a process you still need to support.
  • Stay hydrated and prioritize protein intake to fuel tissue repair.
  • Track range of motion objectively so improvements are visible week to week.
  • Active malignancy without provider oversight.
  • Pregnancy or breastfeeding.
  • Known peptide hypersensitivity.
Important Note The FDA's position on peptides continues to evolve. Availability of specific compounds may change, and not all peptides discussed are currently offered at every visit. Book a consultation with our provider team to discuss your goals, current options, and what's appropriate for you.
