GH Pulse Restoration is a therapeutic objective focused on re-establishing the natural, pulsatile secretion pattern of Growth Hormone (GH) from the pituitary gland, which typically declines with age, a condition known as somatopause. The goal is to mimic the healthy, intermittent release of GH, particularly the large nocturnal pulse, to maximize its anabolic and lipolytic effects while minimizing potential side effects associated with continuous high levels. Restoring this pulse pattern is critical for maintaining lean body mass, bone density, and optimal metabolic function.
Origin
This term is derived from advanced endocrinology and chronobiology, recognizing that the efficacy of Growth Hormone is intrinsically linked to its natural, non-continuous release pattern. The concept of ‘Restoration’ is central to modern peptide and hormonal therapy, aiming to revitalize the hypothalamic-pituitary axis rather than simply supplementing with exogenous hormone.
Mechanism
Restoration is primarily achieved through the use of Growth Hormone Secretagogues (GHSs), such as Ghrelin mimetics or Growth Hormone-Releasing Hormone (GHRH) analogues, which stimulate the pituitary to release its own stored GH in a physiological manner. These agents interact with specific receptors in the hypothalamus and pituitary, thereby amplifying the amplitude of the endogenous GH pulses, particularly during sleep, which is the natural time for the most significant secretion.
