The field needs validated, in vivocompatible flux sensors (O 2 , H 2 O 2 , NO/ONOO ) targeted to matrix/IMS, ER lumen, peroxisomes, plasma-membrane microdomains and nucleus, each with built-in specificity controls and reporting standards (matrix, oxygen tension, m, pH) to disambiguate signalling pulses from damage plateaus
Testosterone esters in oil injected intramuscularly are absorbed slowly from the lipid phase

MOTS-c and Longevity Research Mitochondria are central to the aging process because they regulate energy production, oxidative stress, and cellular survival
Plasma levels plateau despite higher intake, meaning increasing the dose does not proportionally increase systemic exposure
