What is Thymosin Beta-4 (TB-4)?

Thymosin Beta-4 (TB-4) is a naturally occurring peptide found in nearly every cell of the human body, known for its remarkable ability to activate healing and regeneration. It plays a key role in tissue repair, inflammation control, and angiogenesis, making it one of the most researched peptides for musculoskeletal recovery, post-surgical healing, and cellular rejuvenation. At PeptideWebMD, TB-4 is prescribed under medical supervision as part of advanced peptide-based protocols for patients recovering from injury, surgery, or chronic inflammation, or looking to optimize performance and repair capacity.

Note: This product is not approved by the FDA. It is available only via prescription under the supervision of a licensed healthcare provider.

Science & Mechanism of Action

TB-4 acts as a cell-repair signaling molecule, stimulating the body’s natural healing response across multiple tissue types. These combined effects position TB-4 as a foundational peptide for muscle recovery, joint repair, and systemic tissue health.

1

Cell Migration & Repair

Binds to G-actin, promoting cell movement and regeneration at damaged sites.

2

Stem Cell Recruitment

Attracts stem cells to injured tissues for faster healing.

3

Angiogenesis Support

Stimulates formation of new blood vessels for better oxygen and nutrient delivery.

4

Anti-Inflammatory Action

Regulates cytokines to reduce swelling and oxidative stress.

5

Scar Prevention

Minimizes fibrosis and promotes organized tissue remodeling.

Benefits & Clinical Applications

Scientifically supported benefits across multiple health concerns

For Injury & Post-Surgical Healing

  • Speeds up recovery from muscle, tendon, and ligament tears
  • Reduces scarring and fibrosis after surgery
  • Enhances wound closure and skin regeneration

For Performance & Recovery

  • Improves circulation and oxygen delivery to muscles
  • Decreases fatigue and inflammation after intense training
  • Supports faster return to exercise or physical activity

For Systemic & Neural Support

  • Studied for cardiac protection after ischemic injury
  • Promotes nerve and spinal repair in preclinical models
  • May aid autoimmune and chronic inflammatory recovery

Physician-Guided Protocol

Safe, effective dosing under medical supervision

For educational reference only. Final protocol is customized during medical consultation.

Typical Treatment Protocol

Delivery Method
Subcutaneous or intramuscular injection near injured area
Typical Range
2–5 mg per injection, 2–3 times weekly
Duration
4–8 weeks, with maintenance as directed for chronic injuries

Note: All protocols are prescribed and monitored by licensed physicians. Dosing varies based on individual needs, injury severity, and treatment goals. Do not self-administer without medical guidance.

Safety Profile & Considerations

Transparent information about side effects and contraindications

Common Side Effects

  • Temporary fatigue, lightheadedness, or slight injection-site irritation.

Who Should Avoid

  • Because TB-4 stimulates cellular growth and angiogenesis, it should be used with caution in patients with active malignancies or uncontrolled cell-growth disorders.

Frequently Asked Questions

Common questions about Thymosin Beta-4 (TB-4)

Is Thymosin Beta-4 the same as TB-500? +

TB-500 is a synthetic fragment of TB-4 with similar mechanisms but a longer half-life. Both are used in healing and regeneration research.

How soon are results noticed? +

Most patients report improved mobility and reduced inflammation within 1–2 weeks of consistent therapy.

Can TB-4 be used for chronic conditions? +

Yes — it is often included in long-term protocols for degenerative or autoimmune conditions under medical supervision.

Is TB-4 safe to combine with other peptides? +

Yes, especially with BPC-157, CJC-1295, or IGF-1 LR3 to enhance recovery and growth signaling pathways.
