Ghrelin Acetate is a research peptide also known as Lenomorelin. Ghrelin Acetate comes from the natural hormone Lenomorelin made in the gastrointestinal tract. Ghrelin is also called the hunger hormone as it promotes food intake. But, ghrelin is also responsible for GI motility, gastric acid secretion, and growth hormone release. These actions are important in glucose metabolism, food preferences, taste, sleep and wake cycle, learning and memory.
