The Science

Chronic fatigue and low energy are driven by multiple biological factors: mitochondrial dysfunction (reduced cellular energy production), HPA axis dysregulation (cortisol imbalance), declining growth hormone (which affects cellular metabolism and sleep quality), and neuroinflammation. Peptides that address energy work through complementary mechanisms: SS-31 directly targets mitochondrial function, GH secretagogues restore the metabolic and sleep-quality benefits of optimal GH levels, and MOTS-c activates AMPK to improve metabolic efficiency.
