Fadogia agrestis promoters point to research that shows Fadogia agrestis might increase sexual behaviors and raise the level of the male hormone testosterone. 

D-aspartic acid, an amino acid present in neuroendocrine tissues of humans, playing a role in the synthesis of both LH and testosterone. LH, of course, is secreted in a pulsatile fashion, thereby signaling the release of testosterone from the testes. D-aspartic acid is synthesized when aspartate racemase converts L-aspartic acid into D-aspartic acid. Clinical research shows that supplementation with 3 grams (3,000mgs) per day, orally, can result in an elevation in testosterone of up to 33%. Mucuna Pruriens contains L-Dopa which is an amino acid that converts into dopamine. Dopamine is an essential component of our body and it's required for proper functioning of the brain. Research discovered the body converts the amino acid tyrosine into L-dopa; L-dopa is then converted into dopamine.
