Man's secret use of synthetic testosterone for cows nearly destroyed his heart

Key Points:

• A Massachusetts man suffered from severe heart failure and multiple health issues over 11 years, which were later linked to his undisclosed use of illicit anabolic-androgenic steroids (AAS), including trenbolone, a veterinary drug used in livestock.
• His doctors initially struggled to diagnose the cause of his symptoms, which included heart failure, kidney injury, high blood pressure, fatty liver disease, and low testosterone, before uncovering his steroid use during a hospital admission in 2026.
• The case highlights the growing public health issue of AAS abuse, with millions of users in the US, mostly male athletes, and emphasizes that clinicians should be prepared to recognize and treat long-term complications like cardiomyopathy, atherosclerosis, and steroid-induced hypogonadism.
• Treatment involved cessation of AAS and management of heart failure and other conditions, leading to significant improvement in heart function, but recovery from steroid-induced hypogonadism proved prolonged and challenging, potentially taking up to three years.
• The case underscores the need for increased awareness among healthcare providers about the signs of AAS abuse and the complex, lengthy recovery process for affected patients.
