Testagen (KEDG) is a synthetic tetrapeptide with the amino acid sequence Lysine Glutamic Acid Aspartic Acid Glycine; a Khavinson peptide bioregulator developed within the same Russian peptide bioregulator research tradition responsible for Epithalon, Pinealon, and Thymalin in CSD’s range. Hudson Science’s formulation supplies 20mg as a lyophilized vial, preserving peptide structural integrity across storage conditions until reconstitution.
Khavinson peptide bioregulators are a class of short synthetic peptides developed by the St. Petersburg Institute of Bioregulation and Gerontology, designed to interact with specific target tissues through a proposed mechanism of cellular and nuclear membrane penetration followed by binding with DNA and histone proteins. Modulating gene expression in target endocrine tissue rather than operating through conventional receptor ligand surface binding. Testagen’s proposed target tissue is the pituitary gland, where this gene expression modulation is hypothesized to influence endocrine pathways related to gonadotropin signaling and downstream testosterone production. A research focus that distinguishes it from direct androgenic compounds and gonadotropin preparations in CSD’s range by targeting a regulatory level upstream of gonadal hormone production.
It is important to note that Testagen’s research evidence base is currently limited, high quality human clinical trial data supporting its efficacy and safety is not established in peer reviewed literature at this time, and it is not an FDA approved replacement for standard testosterone replacement therapy, HCG, SERMs, or other established HPG axis interventions. Its research interest lies primarily in the preclinical and bioregulator peptide literature examining pituitary targeted peptide gene expression modulation as a mechanism for endocrine pathway influence, rather than in established clinical endocrinology.
Hudson Science formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD stocks Testagen alongside other Khavinson peptide bioregulators including Epithalon, Pinealon, and Thymalin, giving researchers access to the complete bioregulator peptide family for comparative pituitary, pineal, and thymic tissue modulation research from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Reconstitute with bacteriostatic water prior to use. Store lyophilized peptide at 2–8°C away from direct light. Once reconstituted refrigerate and use within 28 days. Intended for research purposes only.
