Anti-Inflammation & Wound Healing
Thymosin Beta-4
TB-500 · Tβ4 · 43-Amino Acid Peptide
A naturally occurring peptide found in virtually every cell and tissue in the body, playing a central role in wound closure, angiogenesis, and tissue protection. Particularly valuable for post-surgical healing and reducing chronic TMJ joint inflammation.
What It Is & How It Works
What is it?
Thymosin Beta-4 (Tβ4) is a naturally occurring 43-amino acid peptide found in virtually every tissue and cell in the body. It is one of the most abundant intracellular peptides in mammals and plays a central role in cell migration, angiogenesis, and tissue protection. TB-500 is the synthetic, stabilized version used therapeutically.
How does it work?
Tβ4 works by sequestering actin monomers (G-actin), which regulates cell motility and enables rapid wound closure. It promotes new blood vessel formation, stimulates keratinocyte and fibroblast migration into wound sites, and modulates the inflammatory response by reducing local inflammatory cytokines — all critical to healing after oral surgical procedures.
Dental & TMJ application
Thymosin Beta-4 accelerates extraction socket healing, reduces post-surgical inflammation after periodontal or implant procedures, supports gingival tissue repair, and reduces inflammatory activity in the TMJ joint capsule — making it valuable for managing chronic TMJ synovitis alongside conventional treatment.
Key Benefits
- Accelerates extraction socket healing and post-surgical tissue closure
- Reduces local inflammatory cytokines following periodontal or implant surgery
- Stimulates fibroblast and keratinocyte migration for rapid wound closure
- Reduces chronic synovitis and joint capsule inflammation in TMJ disorder
- Promotes new blood vessel formation to restore circulation in damaged tissue
- Supports gingival tissue repair in aggressive or refractory periodontitis
Key Benefits
Subcutaneous Injection
Standard delivery — twice-weekly protocol for 4–8 weeks · self-administered with full instruction
Sublingual Spray
Needle-free alternative · absorbed through oral mucosa · slightly lower bioavailability
Note: TB-500 is most commonly administered via subcutaneous injection on a twice-weekly schedule for 4–8 weeks. It is frequently combined with BPC-157 in post-surgical or acute TMJ inflammation protocols for synergistic tissue repair and inflammation control.
Possible Side Effects
- Mild injection site redness or swelling
- Temporary fatigue in early treatment
- Rare: mild headache
- Rare: nausea (less common than oral peptides)
Important Safety Profile
Thymosin Beta-4 has a well-established safety record across extensive preclinical and emerging clinical research. As with any pro-healing peptide, patients with active malignancy should discuss individualized risk-benefit considerations with their provider. Not recommended during pregnancy or breastfeeding.
What to Expect
TB-500 typically shows measurable anti-inflammatory effects within 3–4 weeks. For post-surgical applications, healing milestones are assessed at your scheduled follow-up appointments. For chronic TMJ synovitis, a 4–8 week protocol is typical, often combined with your orthotic or functional TMJ treatment plan.
Regulatory Status
Thymosin Beta-4 / TB-500 is available as a compounded peptide through FDA-regulated compounding pharmacies. It is prescribed off-label. Your provider will review full regulatory status and provide complete informed consent documentation before treatment begins.
