TB-500, also known as Thymosin Beta-4, is a naturally occurring peptide present in almost all animal and human cells. This powerful peptide promotes healing, enhances strength, flexibility and endurance, reduces inflammation of tissue in joints, and encourages hair growth. Research has shown that TB-500 substantially aids in the recovery and healing of injuries that would typically take months to heal, such as tendonitis, ligament damage, and fractures. Its regenerative properties have also been recognized in various kinds of heart tissue. TB-500 is not only effective in athletes for its injury recovery and performance-enhancing properties but also among those suffering from acute and chronic injuries or disease. It offers potential help for individuals looking to promote wound healing, decrease inflammation, and recover faster from surgeries or illnesses.

Benefits：

TB-500 works by controlling the cell-building protein, Actin. The peptide promotes healing, creates new blood and muscle cells, and reduces inflammation in tissues. It plays a significant role in building new blood vessels, new small muscle tissue fibers, cell migration and blood cell reproduction which enables rapid repair and recovery.

The importance of peptides：

Many active substances in the human body are in the form of peptides. Peptides are involved in various fields of human hormones, nerves, cell growth and reproduction, and their importance is to regulate the physiological functions of various systems and cells in the body, activate the relevant enzyme systems in the body, promote the permeability of intermediate metabolic membranes, or control DNA transcription or affect specific protein synthesis, and ultimately produce specific physiological effects. Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information. Peptides can be used as transportation tools in the human body to transport various nutrients and various vitamins, biotin, calcium and trace elements beneficial to the human body to the cells, organs and tissues of the human body. Peptide is an important physiological regulator of the human body, which can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body, and it has important biological functions.

1. How to make an order?

Send me message and let me know what you need with quantity , then i will calculate to you

2. What's the lead time and shipping ways?
We will delivery to the package by FEDEX express to you after receive your payment, it would take around 5-7 days to your address.

3. How do i keep the peptides when i receive it ?
Peptides in the form of lyophilized powder can be transported at room temperature by vacuum packaging, while polypeptides in the dissolved state need to be refrigerated at 2°C - 8°C. For long-term storage, peptides should be stored in the form of lyophilized powder store at -20°C or -80°C in a sealed container with desiccant, which can avoid the degradation of peptides to the greatest extent.

4. What's the payment methods?
We could accept pay through paypal,bank transfer, X-Transfer and bitcoin.

Research

Class:
Actin-sequestering protein / 43-amino-acid peptide

Status:
Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)

Mechanism:
A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.

Activity note:
Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
