Rats fed homobrassinolide, found in the mustard plant, produced an anabolic effect, and increased appetite and muscle mass, as well as the number and size of muscle fibers, according to a new research in The FASEB Journal.

A specific plant steroid when given orally to rats triggered a response similar to anabolic steroids, with minimal side effects, according to the research.

It was also revealed that the stimulatory effect of homobrassinolide on protein synthesis in muscle cells led to increases in lean body mass, muscle mass, and physical performance.
