In this StarTalk Special Edition, Neil deGrasse Tyson and guests Gary O'Reilly and Chuck Nice join Dr. Knock to debunk myths surrounding "looks-maxing" and biohacking. The group examines the science behind GLP-1 drugs, creatine, and peptide stacking, distinguishing between evidence-based medicine and risky gray-market supplements. They also discuss the cultural impact of anti-aging trends, the importance of visceral fat management, and the predatory nature of the testosterone replacement industry.
