Research Overview
BYM338
Clinical trials showed meaningful increases in lean mass, with mixed functional outcomes depending on population and endpoint. The antibody remains one of the best-documented receptor-blocking approaches to muscle anabolism in humans.
Meldonium
Clinical literature focuses on cardiometabolic support and exercise tolerance rather than direct anabolic effects. Any endurance benefit is thought to come from altered substrate handling and improved tolerance to stress.
