A specialized clinical strategy involving the administration of specific compounds, known as secretagogues, that stimulate the body’s pituitary gland to increase the pulsatile and endogenous secretion of Somatotropin, or Growth Hormone (GH). These protocols are designed to safely and physiologically restore youthful GH and Insulin-like Growth Factor 1 (IGF-1) levels without introducing exogenous hormone. This is a targeted approach to enhancing anabolic signaling and regeneration.
Origin
This therapeutic approach emerged from a deeper understanding of the hypothalamic-pituitary axis and the neuroendocrine regulation of Growth Hormone release. The term emphasizes the use of agents that work by signaling to the pituitary, mimicking the natural stimulatory hormones like Growth Hormone-Releasing Hormone (GHRH) or ghrelin mimetics. It is a key area of research in anti-aging and regenerative medicine.
Mechanism
The secretagogues act on specific receptors within the pituitary gland, primarily the GHRH receptor or the ghrelin receptor (GHSR), to trigger the release of stored GH in a pattern that closely mimics the body’s natural, pulsatile secretion, particularly during deep sleep. By increasing the endogenous production of GH, these protocols subsequently elevate circulating IGF-1 levels, which mediate the primary anabolic, lipolytic, and regenerative effects on muscle, bone, and connective tissues.
