This second step requires NAD+ and generates NADH, shifting the hepatic redox state toward reduction and impairing mitochondrial ATP production
The assumption that the same selectivity translates identically in humans with equivalent GH potency and equivalent absence of cortisol/prolactin effects is pharmacologically reasonable but has not been confirmed under controlled human conditions for GH stimulation specifically
Contemporary neuroscience continues to harness EE as a powerful non-pharmacological intervention, enhancing hippocampal neurogenesis and reducing anxiety in rodents (Khalil, 2024), reinstating young cortical plasticity in adult animals (Baroncelli et al., 2010), mediating the rescue of visual functions in adult amblyopia (Sale et al., 2007), promoting favorable memory-related brain activity in older adults (Khalil, 2024), and supporting developmental and behavioral gains in infants at risk for cerebral palsy (Zhou et al., 2025) and autism spectrum disorder populations (Hernndez-Arteaga et al., 2025)
And that will never change
