Insulin Resistance Doctor: They’ve All Been Wrong on Longevity Science

What was said

""Unquestionable. Like that is the simplest truth that I exist in is as we age, we we know what the longitudinal data looks like. It does technically on paper become harder to build muscle as we age.""

Dr John Chef says someone in their 50s could consider testosterone and a peptide “stack” to help build muscle. He argues hormone optimisation supports longevity via muscle and metabolic health, and says baseline biomarkers should guide any pharmacological support alongside training.
