Testagen, alternatively known as KEDG, is classified among the Khavinson peptides and functions as a short signaling peptide. Short peptides such as Testagen are also suggested to serve as bioregulators which means that they may potentially cross both the cell and nuclear membranes to interact directly with DNA of target tissues.(1) Potentially, it may interact with the function of the anterior pituitary gland cells and interact with endocrine pathways that play a role in the synthesis of testosterone and thyroid-stimulating hormone (TSH).(2) This is likely due to the synthesis of Testagen, which is based on the amino acid composition of extracts from the anterior lobe of the pituitary gland.(3) As a result, it is made of the amino acids lysine, glutamine, asparagine and glycine, forming a tetrapeptide.
