Testagen (20mg) – Premium Research Tetrapeptide for Endocrine Studies

Welcome to Liaocheng Yixin Company, your trusted source for premium testagen 20mg for research. As a specialized peptide synthesis manufacturer operating from our facility at No. 9 Lushan Road, Dongcheng Street, Liaocheng Economic and Technological Development Zone, Shandong Province, we provide high-quality research compounds for the global scientific community.

Testagen is a short signaling peptide also known as KEDG, classified among the Khavinson peptides. It functions as a bioregulator that may cross cell and nuclear membranes to interact directly with DNA of target tissues . Our testagen 20mg for research offers investigators a reliable, high-purity compound for endocrine, reproductive health, and epigenetic research applications.

What is Testagen?

Testagen (CAS: 1026993-38-3) is a tetrapeptide consisting of the amino acid sequence Lys-Glu-Asp-Gly (KEDG) . It is also referred to as Anterior Pituitary Peptide (APP) due to its synthesis being based on the amino acid composition of extracts from the anterior lobe of the pituitary gland .

Key identifiers:

• CAS Number: 1026993-38-3 

• Molecular Formula: C17H29N5O9 

• Molecular Weight: 447.44 g/mol 

• Sequence: H-Lys-Glu-Asp-Gly-OH (H-KEDG-OH) 

• Synonyms: KEDG, Anterior Pituitary Peptide (APP) 

• Purity: ≥99% verified by HPLC 

Mechanism of Action in Research

Testagen exerts its effects through several distinct mechanisms:

Endocrine System Regulation

Testagen is a bioregulator that stimulates and regulates the functions of the endocrine system . It acts primarily on the anterior pituitary gland and ultimately on the thyroid gland . Through these effects, it is able to normalize the production of testosterone and thyroid hormones under certain conditions .

Gene Expression Modulation

Like many short peptides, Testagen crosses cell membranes and nuclear membranes and interacts directly with DNA . It binds to histone proteins and DNA, potentially modulating gene expression linked to hormonal activity . Studies suggest it may influence epigenetic mechanisms, affecting cellular activities and differentiation .

Potential Immune Function Support

Research indicates Testagen has the potential to induce the differentiation of stem cells into immune system cells, suggesting positive implications for immune function .

Scientific Research Applications

Testagen has been studied across several research domains:

Hypothalamic-Pituitary-Gonadal Axis Research

• Research suggests Testagen may interact with the pituitary gland to upregulate testosterone production 

• Studies indicate it may enhance testosterone production in research models of chronic inflammation and low testosterone 

• Potential to improve uroflowmetry indicators and reduce markers of inflammation in prostate research models 

Hypothalamic-Pituitary-Thyroid Axis Research

• Research conducted on hypophysectomized avian models demonstrated Testagen’s impact on thyroid function and morphology 

• Testagen administration resulted in an apparent 23% increase in body weight and positive morphological adaptations in thyroid tissue 

• Studies noted restoration of thyroid functions and morphology, with greater effects observed in younger models 

Epigenetic and Chromatin Research

• Testagen has been observed to bind to specific histone regions, suggesting a potential impact on chromatin structure and gene expression 

• Interaction with histones and histone-deoxyribooligonucleotide complexes indicates a site-specific nature influenced by peptide primary structure 

Corrosion Inhibition Research (Novel Application)

• A 2025 study published in Molecules investigated Testagen (KEDG) as a copper corrosion inhibitor 

• KEDG achieved approximately 86% inhibition efficiency in sodium chloride solution 

• The tetrapeptide demonstrated a mixed action mechanism involving both chemical and physical spontaneous adsorption 

• Computational studies using DFT and Monte Carlo simulation confirmed experimental results
