Claims for GH as an anti-aging treatment date back to 1990 when the New England Journal of Medicine published a study wherein GH was used to treat 12 men over 60.  At the conclusion of the study, all the men showed statistically significant increases in lean body mass and bone mineral density, while the control group did not. The authors of the study noted that these improvements were the opposite of the changes that would normally occur over a 10- to 20-year aging period. Despite the fact the authors at no time claimed that GH had reversed the aging process itself, their results were misinterpreted as indicating that GH is an effective anti-aging agent.    This has led to organizations such as the controversial American Academy of Anti-Aging Medicine promoting the use of this hormone as an "anti-aging agent". 
Also known as “velvet bean”, Mucuna pruriens is a tropical plant that is known for its ability to reduce the level of prolactin (a female hormone) in the bloodstream. As the male body contains both male and female hormones, Mucuna pruriens lowers prolactin levels in men, which helps to prevent testosterone depletion. Another important benefit of Mucuna pruriens is its ability to lower the level of cortisol (. the “stress hormone”) in the bloodstream. Clinical research shows that cortisol essentially dismantles testosterone molecules before they are even able to leave the testes.
