    A: We will delivery to the package by USPS, FEDEX, DHL paket and other dedicated transportation to you after receive your payment, it would take around 10-15 workdays to your address.

    Q: How do i keep the peptides when i receive it ?
    A: 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.

    Peptide Storage Guidelines: General Tips
    When storing peptides, remember to:
    • Store peptide in a cold, dry, dark place
    • Avoid repeated freezing and thawing of peptide
    • Avoid overexposure to the air
    • Avoid light exposure
    • Avoid storing peptides in solution long term
    • Aliquot peptide according to experimental requirements

    • Product Application
    • 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.

    TB 500 is a synthetically made version of TB4 that facilitates healing and recovery by helping build new blood vessels, muscle tissue fibers, blood cells, and facilitating cell migration. It acts on the muscular system and has anabolic properties. TB 500 is used primarily for race animals (horses and dogs).

    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.
