What is the Origin of Selective GHRPs?

The term is rooted in peptide chemistry and endocrinology, emerging from the discovery of ghrelin and its receptor in the late 20th century. The "Selective" designation differentiates them from earlier, less specific GH-releasing agents, emphasizing their targeted action on the GHSR pathway. This class of compounds represents a more nuanced, regulatory approach to managing the somatotropic axis.

What is the Mechanism of Selective GHRPs?

The mechanism of Selective GHRPs involves binding to the GHSR, primarily located in the pituitary gland and the hypothalamus. This binding action mimics the effect of ghrelin, triggering a signaling cascade that stimulates the somatotroph cells in the anterior pituitary to release GH in a pattern closely resembling natural pulsatile secretion. By working upstream in the hypothalamic-pituitary axis, these peptides support the physiological feedback loops that govern GH and IGF-1 levels.

Selective GHRPs

Meaning

Selective GHRPs, an acronym for Selective Growth Hormone Releasing Peptides, are a class of synthetic secretagogues designed to stimulate the pulsatile release of endogenous growth hormone (GH) by acting on the ghrelin/growth hormone secretagogue receptor (GHSR). Unlike direct GH administration, these compounds work by enhancing the body’s natural signaling mechanisms, offering a more physiological and potentially safer method for optimizing GH levels. They are utilized in clinical contexts to address age-related decline in GH secretion.
