The muscle bank of amino acids is what allows for visceral mass and function, at the expense of muscle mass.
Aging in fact occurs from a decline in muscle mitochondrial function leading to reduced oxidative and phosphorylation there leading to accumulation of fat in muscle and liver, so also contributing to insulin resistance in older adults.
Thus, if you protect your muscle mitochondria, you can protect against aging and insulin resistance. You can protect your muscle mitochondria if you reduce oxidative free radicals within mitochondria. You can reduce oxidative free radicals in muscle mitochondria with synthetic GH if dosed at physiologic concentrations, i.e., what you get from peptide up regulation of GH. If supraphysiologic concentrations of exogenous GH are used, this antioxidant effect is reduced, but not enough to disrupt mitochondrial function.
So using only peptides to increase GH is nicely protective to maximizing anti-oxidative muscle protection.
Using only peptides to increase GH is nicely protective to maximizing muscle ATP production.
But even with peptides, you can maximize this optimization. So they must be cycled. Pulsing peptides is key.
Conclusion
Amino acids, their stores in our muscle, are the key to warding off aging.
