       Product Detail   


    Here is an English product overvied for Testagen  :

    Composition:
    Testagen is a synthetic tetrapeptide bioregulator with the amino acid sequence Lys-Glu-Asp-Ala (KEDA/Lys-Glu-Asp-Ala), sharing structural identity with certain epitopes of chromatin-associated proteins; it is synthesized via solid-phase peptide synthesis, has a molecular weight below 500 Da, and is provided as a high-purity lyophilized powder intended strictly for laboratory research.

    Mechanism of Action:
    It is hypothesized to act as a cytogen (short peptide bioregulator) that penetrates the nuclear membrane of target cells—particularly hepatocytes and Leydig or steroidogenic cell models—where it binds to specific DNA promoter regions and induces localized chromatin decondensation, thereby partially reversing age-related gene silencing and facilitating the transcriptional reactivation of proteins involved in steroidogenesis, cellular metabolism, and tissue-specific repair pathways.

    Research Advantages:
    Testagen’s low molecular weight permits efficient cellular uptake and nuclear localization without requiring carriers; its epigenetic modulatory activity allows researchers to study peptide-induced reversal of gene silencing distinct from classical hormone receptor agonism, and it demonstrates minimal cytotoxicity and low immunogenicity in vitro. As a short, stable peptide, it offers reproducible dose–response behavior in cell-based models of endocrine or hepatic aging and serves as a useful tool for investigating peptide-mediated gene expression restoration.

    Intended Research Population:
    This compound is designated for non-clinical, in vitro, or ex vivo studies focused on age-related declines in androgen-axis gene expression, chromatin condensation models, male reproductive tissue aging, hepatocyte metabolic restoration, and comparative bio regulator screening; it is an investigational research reagent not approved for therapeutic, diagnostic, or human/animal administration outside controlled scientific experimentation.
