Dosage Information

  • Reconstitute: Add 3.0 mL bacteriostatic water → ~3.33 mg/mL concentration.
  • Typical daily range: 500–1000 mcg once daily (gradual titration recommended).
  • Easy measuring: At 3.33 mg/mL, 1 unit = 0.01 mL ≈ 33.3 mcg on a U‑100 insulin syringe.
  • Storage: Lyophilized: store at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F); do not freeze reconstituted solution.

Product Description:

TB-500 (also known as Thymosin Beta-4 fragment or TB4 fragment) is a synthetic heptapeptide (sequence: Ac-LKKTETQ) consisting of 7 amino acids. It is a fragment of the naturally occurring 43-amino-acid protein Thymosin Beta-4 (Tβ4), which is found throughout the body (especially in platelets, wound fluid, and tissues involved in repair).

How It Works

TB-500 primarily works by mimicking key functions of Thymosin Beta-4, with its main mechanism centered on actin regulation:

  • Actin sequestration and cell motility: It binds to G-actin (monomeric actin), helping regulate the polymerization/depolymerization of actin filaments. This promotes cell migration, shape changes, and movement of repair cells (like fibroblasts, keratinocytes, and stem cells) to sites of injury.
  • Angiogenesis: Stimulates the formation of new blood vessels to improve nutrient/oxygen delivery to damaged tissues.
  • Anti-inflammatory and anti-apoptotic effects: Reduces excessive inflammation, inhibits programmed cell death in stressed cells, and supports tissue remodeling with less scar formation.
  • Tissue regeneration: Enhances collagen deposition, wound healing, and overall repair processes in muscles, tendons, ligaments, skin, and other tissues.

These effects make it more “systemic” in action compared to more localized peptides. Most evidence comes from preclinical (animal and in-vitro) studies on wound healing, muscle/tendon injuries, and inflammation models. Limited human data exists for the full Tβ4 protein (some small Phase 2 trials on topical use for wounds), but very little for the TB-500 fragment itself.

Potential Benefits and Why People Use It

In fitness, bodybuilding, regenerative medicine, and recovery communities, TB-500 is popular for:

  • Accelerated injury recovery — especially soft tissue (muscles, tendons, ligaments), wounds, and post-surgery healing.
  • Reduced inflammation and pain — helpful for chronic conditions, joint issues, or overuse injuries.
  • Improved flexibility and mobility — by supporting tissue remodeling and reducing scar tissue.
  • Systemic repair and endurance — potential benefits for overall recovery, cardiovascular health, and hair/skin regeneration in some studies.

It is often stacked with peptides like BPC-157 (BPC more localized/gut-focused; TB-500 more systemic/motility-focused), as they may complement each other for comprehensive healing.

Important Caveats

  • Limited human evidence: Strong preclinical data, but robust, large-scale human clinical trials on TB-500 (the fragment) are lacking. Ongoing early-phase trials (e.g., for cardiovascular biomarkers) are exploring safety.
  • Regulatory status: Not FDA-approved for any medical use. It is banned by WADA for athletes and sold as a research chemical. Quality/purity of products varies widely.
  • Safety: Generally well-tolerated in animal studies with low toxicity reported, but human long-term safety data is minimal. Theoretical concerns include potential effects on cell migration in cancer contexts (though not strongly evidenced). Common anecdotal side effects are mild (e.g., injection-site reactions, fatigue, or headaches). Consult a healthcare professional before use.

Bottom line: TB-500 is a promising research peptide for tissue repair, flexibility, and recovery, driven by its role in actin dynamics and regeneration. It’s particularly appealing for athletes or those dealing with stubborn injuries. However, its use remains experimental due to limited human data and lack of regulatory approval. For your e-commerce peptide products (like at EDB LLC), emphasize high-quality sourcing, disclaimers, and the research-only context. Always prioritize professional medical advice.
