The therapeutic application of specific growth hormone-releasing peptides (GHRPs) or growth hormone-releasing hormone (GHRH) analogues to stimulate the pituitary gland’s natural, pulsatile secretion of endogenous Growth Hormone (GH). This approach aims to mitigate the somatopause, the age-related decline in GH and Insulin-like Growth Factor 1 (IGF-1) levels, to improve body composition, skin integrity, and overall vitality. It represents a more physiological and regulated alternative to direct GH replacement therapy.
Origin
This concept originates from clinical endocrinology and peptide science, focusing on the discovery and synthesis of small protein chains (peptides) that modulate the somatotropic axis. The “Anti-Aging” descriptor reflects the observed clinical outcomes of improved muscle mass, reduced visceral adipose tissue, and enhanced tissue repair, all of which are associated with more youthful GH secretion patterns.
Mechanism
These peptides act as secretagogues, binding to specific receptors on the pituitary somatotroph cells, triggering a release of stored GH in a pattern that closely mimics the body’s natural pulsatility. This induced GH then stimulates the liver to produce IGF-1, which mediates most of the anabolic and regenerative effects on bone, muscle, and collagen synthesis. The physiological pulse pattern minimizes the negative feedback and potential side effects often associated with continuous exogenous GH administration.
