Evidence-based guidance on the systems that keep men functioning well: sleep, energy, recovery, nutrition, and long-term health markers. Articles here draw on peer-reviewed research and explain what the evidence actually supports, not what supplement marketing claims.
Screening recommendations carry letter grades, and the grade tells you more than the age band does. Why the PSA test is a C, why colorectal screening moved to 45, and how to read the code before you accept a test.
