ACTH 1-14, a fragment of the adrenocorticotropic hormone, is primarily used in research and clinical studies to investigate the role of the hypothalamic-pituitary-adrenal (HPA) axis. It is employed to study adrenal gland function and the release of cortisol, aiding in understanding stress responses and related disorders. Additionally, it is utilized in experimental settings to explore its potential effects on cognitive functions, mood regulation, and immune system modulation. Researchers also use ACTH 1-14 to develop diagnostic tools for adrenal insufficiency and other endocrine disorders. Its applications extend to studying peptide hormone interactions and their therapeutic potential in various medical conditions.
