Methyl Test

D-Aspartic Acid breaks down into N-Methyl-D-Aspartate via a methyl transference reaction called NMDA Synthetase. N-Methyl-D-Aspartate then stimulates the Hypothalamus-Pituitary and testes to produce hormones. So, if you take D-Aspartic Acid, it is the N-Methyl-D-Aspartic Acid, which gets there through conversion, that actually does the work by increasing testosterone levels as well as growth hormone and luteinizing hormone.
