THE HORMONAL OPTIMIZER
KEDG; Anterior Pituitary Peptide
Testagen is a synthetic tetrapeptide that targets the anterior pituitary gland. It enhances secretion of TSH (thyroid stimulating hormone), LH (luteinizing hormone), and FSH (follicle stimulating hormone), thereby supporting both thyroid function and testosterone production. It's used for andropause, low testosterone, thyroid support, and general hormonal optimization.
