Dr. Darsh Shah and Dr. Altamash Raja continue their conversation with Dr. Shawn Arent on hormone physiology and performance. They dive into female physiology and menstrual cycle myths, the overlooked role of thyroid and reverse T3, catecholamines and autonomic balance, and the future of performance enhancement with GLP-1s and muscle-preserving drugs. A practical, evidence-based look at optimizing health and performance!
