Despite what most guys think, hormones are just as important for them as they are for women. However, by the age of 30, the typical man's testosterone levels start to drop 1 percent each year, which can result in less muscle, less energy, more fat, and a flagging sex drive.

After a decade of research, health and fitness expert John Romaniello has discovered safe, natural, and highly effective ways to produce more testosterone and bring about remarkable changes in a man's body. His program is based on cutting-edge science that counters the online "noise" about male hormones.

In Engineering the Alpha, Romaniello and Adam Bornstein, editorial director of Livestrong.com, present a powerful way to improve physical, emotional, sexual, and psychological health for men. From research in Olympic labs to real-life results with their clients, they are reinventing masculinity and showing every man how to be who he wants to be.
