Sermorelin Acetate, also known as GRF 1-29, is a Growth Hormone Releasing Hormone (GHRH) produced by the brain that stimulates the production and release of Growth Hormone (GH). Sermorelin Acetate was first developed in the 70s, which is thought to be the shortest fully functional fragment of GHRH and has been used as a test for Growth Hormone secretion. It is often used extensively in Anti-aging Therapy along with Testosterone in men. Sermorelin Acetate affects a more primary source of failure in the GH neuroendocrine axis, has more physiological activity, and its use for adult hormone deficiency is not restricted. Compared to human Growth Hormone (hGH), Sermorelin Acetate is a growth hormone secretagogue, which means that it stimulates the pituitary gland to produce and secrete growth hormone. Also, Sermorelin Acetate and Modified GRF 1-29 contains 29 amino acids whereas hGH is a larger molecule containing 191 amino acids.
