Greg Paul, Ph.D., director of health and nutrition for The Solae Company says:
"The results of this study show that soy protein is just as effective as whey protein in building lean muscle mass as part of a dedicated exercise and nutrition regimen, while contradicting the myth that soy protein may negatively impact testosterone levels in men. "These results are consistent with prior studies which have compared the effect of whey protein and soy protein on lean muscle mass, and supports the notion that dedicated athletes may benefit from a nutrition regiment that includes both soy and whey proteins."
Douglas S. Kalman, M.S, R.D., Director of Nutrition & Applied Clinical Research at Miami Research Associates says:
"We believe that this study validates that soy protein is safe and just as effective as whey protein in helping exercising males achieve their fitness goals and supports the development of lean muscle mass."
