Defense Secretary Pete Hegseth has announced a testing initiative aimed at optimising the physical readiness of all U.S. service members.

In a video on X titled High‑T Department, Hegseth confirmed that the program will ensure troops with adequate testosterone levels are ready “at their absolute best.”

From the outset, every active‑duty and reserve member over the age of 30 will receive an annual screening; younger men can opt in whenever they wish. Torjours with low testosterone will be offered voluntary replacement therapy.

Pentagon spokesperson Sean Parnell signaled that the screening is effective immediately and will be enforced across all military components.

The US Food & Drug Administration (FDA) had last month eased certain labeling restrictions on testosterone, prompting the current screening push.

Medical professionals caution that testosterone therapy can have serious side effects. Dr. Mohit Khera of Baylor College of Medicine notes that rising muscle mass and improved energy come at the cost of possible infertility and increased cardiac risk.

Hegseth’s statement follows earlier calls by Health Secretary Robert F. Kennedy Jr to lift barriers for clinicians to prescribe testosterone, citing a national fertility crisis.

The program is positioned as a quintessential example of advanced medical care for our warriors, underscoring a dual focus on immediate combat performance and long‑term health.
