What is the Origin of Growth Hormone Secretagogue Dosing?

This clinical concept evolved with the development of synthetic GHS peptides, such as Ghrelin mimetics, which provided a non-replacement method to enhance endogenous GH production. The term combines the drug class, "Growth Hormone Secretagogue," with "Dosing," the pharmaceutical science of determining appropriate amounts. It emphasizes a nuanced approach to hormonal support, favoring stimulation over direct replacement.

What is the Mechanism of Growth Hormone Secretagogue Dosing?

Effective GHS dosing is achieved by timing the administration to synchronize with the body's natural circadian and ultradian rhythms, particularly just before the onset of the deep sleep window. The GHS binds to specific receptors in the pituitary and hypothalamus, triggering the release of endogenous GH. Strategic dosing maintains the physiological pulsatility of GH, which is crucial for maximizing its anabolic and lipolytic effects while preventing the negative feedback that could lead to pituitary desensitization.

Growth Hormone Secretagogue Dosing

Meaning

The precise, individualized determination of the quantity, frequency, and timing of administration for a Growth Hormone Secretagogue (GHS), a class of compounds that stimulates the body’s natural release of Growth Hormone (GH). Optimized dosing protocols aim to mimic the natural, pulsatile release pattern of GH, particularly the large pulse associated with deep sleep, thereby maximizing therapeutic benefit while minimizing potential side effects. This clinical practice is central to restorative endocrinology.
