TB-500 Nasal Spray

$109.00

TB-500 is a synthetic peptide fragment of thymosin beta-4, a natural protein found in nearly all human and animal cells. Thymosin beta-4 is involved in cell movement, growth, and survival, but is also engaged on a larger scale in tissue repair, healing, and anti-aging research.

In scientific research, TB-500 is studied for several biological activities, including

  • Tissue Repair and Wound Healing: Studies show that TB-500 can speed the healing of damaged muscles, tendons, ligaments, and skin.
  • Anti-Inflammatory Actions: TB-500 shows anti-inflammatory effects that support recovery from injuries, surgical wounds, and chronic inflammatory conditions.
  • Cardiovascular & Circulatory Support: It may improve blood vessel repair and heart tissue recovery.
  • Hair and Skin Health: Some suggest that TB-500 can support hair growth and skin regeneration by working on the follicle and dermal cells.

Our 10 mL research solution contains 8 mg total TB-500, prepared in a convenient nasal spray format. Each spray releases 100 mcg, with a total of 80 sprays per bottle, allowing for precise measurements.

Please note that all payments include a 3.99% processing fee set by our international payment processor.

What is TB-500?

TB-500 is a peptide fragment of thymosin beta-4, a naturally occurring protein in all human and animal cells. TB-500 was developed as a shorter version of this protein, making it easier to study in laboratory research thymosin beta-4’s potential connection to wound healing, tissue regeneration, and recovery after injury or surgery.

TB-500 Chemical Information

  • Identify (peptide sequencing verification) Purity (≥99% by HPLC)
  • Absence of contaminants (microbial, heavy metals, solvents)
  • Lab testing ensures that the material provided is consistent, high-quality, and suitable for research purposes.

Research Related to TB-500

Here are some highlighted areas of research related to TB500. While these studies are promising, TB-500 isn’t approved as a drug or dietary supplement, which means its use remains limited to research.

Tissue Repair & Wound Healing

Animal and cell studies show that TB-500 can speed wound healing of damaged muscles, tendons, ligaments, and skin. TB-500 works through an interaction with actin, a protein that gives cells their shape and helps them move. Instead of letting actin form long chains, TB-500 keeps some of it in a “ready-to-use” form, which is important for healing as it allows cells to move to where they’re needed quickly, such as injury sites, to help rebuild damaged tissue [1, 2].

Anti-Inflammatory Actions

TB-500 displays anti-inflammatory effects, supporting recovery from sports injuries, chronic conditions like arthritis, and surgical wounds. It works through several mechanisms, one of which is decreasing the pro-inflammatory cytokine production, tipping the immune response into healing, rather than chronic inflammation [3].

Collagen Deposition & Scar Reduction

In studies, TB-500 was shown to encourage collagen production and matrix remodelling, contributing to stronger and more flexible repaired tissue and less scar formation, which is important for healing muscle, tendon, ligament, and even skin injuries [4]
