Mitochondrial health: SS-31, MOTS-c and NAD+ in the research on cellular energy
SS-31, MOTS-c and NAD+ each reach mitochondrial energy production by a different route: a peptide that binds a membrane lipid, a peptide encoded in mitochondrial DNA that signals through AMPK, and the coenzyme the respiratory chain runs on. This guide follows what their cell, animal and human studies measured, the positive results and the null ones alike.

What is GHK-Cu? The copper peptide research so far
GHK-Cu is a copper-binding tripeptide identified in human plasma that has been studied in fibroblast cultures, animal wound models and a small number of human trials. This guide sets out what those gene-expression, skin-model and topical human studies measured, and what has not yet been shown.
