Many studies have shown that multiple pathways can negatively regulate the kinase activity of the c-Met receptor
The majority of respondents (75%) identified as women, followed by men (24%) and non-binary individuals (1%)
Over time, this can lead to: Loss of lean body mass and lower resting metabolic rate Reduced protein intake , making it harder to maintain muscle Micronutrient deficiencies , particularly vitamin D, calcium, magnesium, and B-vitamins Lower energy levels and slower recovery from illness or exercise (Mozaffarian, 2025) Gastrointestinal side effects can make the picture even more complex

How it works: GHRH receptor binding: Sermorelin binds pituitary somatotroph GHRH receptors, activating adenylyl cyclase and increasing intracellular cAMP to trigger synthesis and pulsatile release of endogenous GH IGF-1 upregulation: elevated GH drives hepatic IGF-1 production, which mediates the downstream anabolic effects including lean mass accretion, bone density support, and tissue remodeling Preserved feedback regulation: because sermorelin works through the hypothalamic-pituitary axis rather than bypassing it, natural somatostatin-mediated negative feedback remains intact, reducing the risk of GH excess seen with exogenous HGH Extracellular matrix support: preclinical models suggest GH axis stimulation may reduce inflammatory cytokine signaling and promote extracellular matrix remodeling, contributing to faster soft tissue recovery Administration: Subcutaneous injection (intramuscular also used) Typical dosing range: 200-500 mcg once daily, most protocols use 300 mcg nightly
