    Product use


    Peptide-based products possess diverse functional advantages in various application scenarios:
    In the field of health management, peptides support metabolic regulation (helping specific groups control blood sugar and maintain a healthy weight) and immune system regulation, enhancing the body's defense response;
    In the field of skin care, peptides can promote the repair of the skin barrier, stimulate the synthesis of collagen to reduce fine lines, and improve the moisture and elasticity of the skin.
    In sports nutrition, peptide substances help with muscle recovery by reducing post-exercise tissue damage and promoting muscle protein synthesis.

    Frequently Asked Questions


    Question: What are the delivery time and transportation method?
    Answer: After receiving your payment, we will send the package to you via United States Postal Service, FedEx, DHL Parcel or other designated transportation methods. It will take approximately 10 to 15 working days to reach your address.
    Q: How should the peptide be stored after receiving it?
    A: The freeze-dried powdered peptide can be transported at room temperature in vacuum packaging, while the dissolved peptide needs to be refrigerated at 2℃ - 8℃. For long-term storage, the freeze-dried powdered peptide should be stored in a sealed container with desiccant and placed at -20℃ or -80℃, which can minimize the degradation of the peptide to the greatest extent.

    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.
