The decline of human growth hormone with age has been linked to decreased lean body mass and skin tone, and increased adipose tissue. Men and women who have consumed the right combination of the amino acid L-arginine and cofactors notice the effects of increased growth hormone activity, however, the unpalatable taste of L-arginine has kept many people from following an effective GH-releasing program. PowerFit™ is a pleasant-tasting formula which combines L-arginine and the nutritional cofactors necessary to enhance the body's own growth hormone release. Used before a workout, PowerFit supports the release of growth hormone to maximize results. PowerFit can also be used before bedtime to enhance the growth hormone production that naturally occurs during sleep in young, healthy individuals.
