Dr. Dwayne Jackson is a health specialist, medical educator, scientist, and entrepreneur with a PhD in neurovascular physiology. Mitochondrial peptides may be promising, but they cannot replace the aerobic base that makes their effects measurable. Dr. Dwayne Jackson explains AMPK and mitochondrial signaling, what MOTS-c and SS-31 can and cannot tell us, and why fitness data, training, and recovery come before any experimental compound. Expect to learn how aerobic fitness supports strength and Strongman training, why lactate clearance and conditioning can become the rate limiter, what AMPK and mTOR signal, how kidney disease changed Dwayne’s perspective on aerobic capacity, where the evidence for MOTS-c and SS-31 is limited, how to design a more useful N-of-1 experiment, and why training, nutrition, recovery, COAs, and third-party testing come before experimental compounds.
