What is the Origin of Growth Hormone Secretagogue Cycling?

This protocol is derived from endocrinology research focusing on the pulsatile nature of the somatotropic axis, recognizing that continuous stimulation often leads to receptor downregulation. Cycling respects the physiological pattern of GH release, which naturally occurs in bursts, primarily during deep sleep. The origin is in optimizing the therapeutic index for GH-related interventions.

What is the Mechanism of Growth Hormone Secretagogue Cycling?

The mechanism relies on allowing periods of non-stimulation between doses, which permits the GH receptors to recover their sensitivity and replenish intracellular signaling components. This intermittent exposure maintains the responsiveness of the pituitary somatotrophs to secretagogues. By mimicking the body's natural pulsatility, cycling promotes sustained IGF-1 elevation without inducing chronic suppression of the axis.

Growth Hormone Secretagogue Cycling

Meaning

Growth Hormone Secretagogue Cycling is a therapeutic strategy involving the intermittent administration of agents that stimulate endogenous Growth Hormone (GH) release, such as GHRH analogs or GHRPs, rather than continuous exposure. This cycling approach is employed to maximize the anabolic and regenerative benefits while mitigating potential desensitization or negative feedback mechanisms associated with constant stimulation. It is a refined application of pulsatile endocrine dynamics.
