Why Everyone's Using GLPs Wrong with Dr. Melissa Grill-Petersen

Episode Description from the Publisher

This: One in eight Americans is on a GLP. It's been called the biggest medical breakthrough since penicillin. The drug is now pretty much everywhere. Yet, Dr. Melissa thinks almost everyone is using it wrong. Dr. Melissa Grill-Petersen is the CEO of Peptide University, the founder of Human Longevity Global, and one of the leading voices on peptide therapy and longevity. She's trained thousands of clinicians worldwide, sits on the board of the American Peptide Association, and works with everyone from doctors in the field to advisory boards inside global pharma. Her argument is simple. The drug is not the problem, it's the dosing. Most people are on far more than they need, for far longer than they need to be. The sarcopenia, the hair loss, the blunted pleasure response, even the rising divorce rates, all of it traces back to dosing.
