Hard Evidence

The Modern Man’s Guide to Sex, Health, and the Male Body

The men’s health space has never been louder — supplements, biohacks, testosterone clinics, influencer protocols. What’s real? What’s noise? What’s dangerous?

Hard Evidence is exactly what it sounds like: a urologist’s evidence-first tour of sex, health, and the male body. Dr. Shusterman weighs the actual research behind the claims men encounter every day and delivers verdicts you can act on.

Skeptical, funny where it should be, and rigorous where it counts.
