Where can you find the studies discussed here?

Weight and strength claims need evidence. The papers below support the findings explained on the substance pages.

What did these papers investigate?

Weight studies of tirzepatide and semaglutide treated people. AOD-9604 animal findings did not become useful human weight loss. MOTS-c mostly involved mice or cells; human blood studies gave nobody treatment. StatPearls is a medical reference book. The substance pages explain each paper's findings and limits in plain words.
