Anti-aging medicine has become a serious industry in the United States, and this film goes inside the clinics, conferences, and labs where doctors sell hormone therapies, supplements, and lifestyle regimens promising to slow the clock. Practitioners in the 'age management' field explain their methods, from testosterone and human growth hormone treatments to blood tests that claim to measure biological rather than chronological age. Patients describe why they pay out of pocket for treatments many mainstream doctors won't prescribe, chasing more energy, muscle tone, and libido decades past the point their bodies would normally provide it. The film sets these true believers against skeptical scientists and physicians who question whether the evidence supports the claims, and who warn about the risks of unregulated hormone use. Running through it all is the older, stranger history of the quest to reverse aging, from dubious tonics to serious endocrinology. The film stays with the tension rather than resolving it: is this the future of medicine or a very expensive placebo?
