Using D-Aspartic Acid is potentially one of the most powerful and natural ways to enhance testostosterone production without having to resort to hormonal ingredients. D-Aspartic Acid is a naturally occurring endogenous amino acid formed in the body, and is suggested to play an important roll in the development of the nervous system. It is present in nervous tissues and endocrine tissues of the body. D-Aspartic acid has been shown to be present in semen, in addition to spermatozoa. There is also a direct relationship between the concentration of D-Aspartic acid and semen quality. D-Aspartic acid plays a powerful roll in the production of sperm cells and biosythesis of sex hormones, including luteinizing hormone and testosterone.

In one study, the effects of sodium d-aspartate were investigated on luteinizing hormone and testosterone levels in 12 men between the ages of 27-67 years. Men took either a placebo or sodium d-aspartate in the morning, following their breakfast meal, and for 12 days. Blood values were drawn pre-trial and then again on days 1, 5, 10, and 20 following the end of the trial.

On the 1st day following the end of the 12 day trial, eleven out of twelve men experienced an average increase in LH levels ranging between and 18-112%, with the average being 46%. Eleven out of twelve men also displayed significant increases in testosterone production ranging from 10-84%, with the average being 45.5% increase in naturally produced testosterone. Surprisingly, a rise in LH and testosterone was also noted in men between the ages of 65-67.

On days 5, 10, and 20 following the end of the trial, the testosterone increases in men taking sodium D-aspartate lowered to a 30.6% increase above baseline, 12.8% increase above baseline, and then back to normal testosterone baseline values respectively. This evidence suggests that D-Aspartic acid builds up in the body and can have effects on LH and testosterone secretion when supplementation ends. A second study, using 23 men in the test group, showed similar results.

Evidence suggests that D-Aspartic acid increases cAMP in the testes, and cGMP in the pituitary. Both cAMP and cGMP act as secondary messengers. In the pituitary, cGMP influences luteinizing hormone production, and more cGMP is believed to lead to more LH. LH is important because it is the hormone that travels from the pituitary down to the leydig cells of the testes. Inside the leydig cells it signals testosterone production. Enter cAMP.

cAMP acts as a secondary messenger that increases StAR expression. StAR is a carrier protein that helps bring cholesterol, the building block of testosterone, into the testosterone manufacturing power plant of the leydig cells. Thus, more cAMP is believed to lead to more testosterone production.

D-Aspartic acid may also increase human growth hormone output. When using D-Aspartic acid, animal studies reveal high concentrations of endogenous NMDA (N-methyl-d-aspartic acid) in the brain. D-Aspartic acid is converted into NMDA which enhances the release of Growth Hormone Release Hormone (GHRH) and Gonadotropin-releasing hormone (GnRH), also known as luteinizing-hormone releasing hormone (LHRH). GHRH does exactly what is sounds like, releasing growth hormone into the body. However, while human trials specifically measuring for this outcome are needed, it is certainly an interesting possibility to consider and welcome effect if D-Aspartic acid does increase concentrations of human growth hormone. The benefits of human growth hormone are certainly very advantageous to athletes and bodybuilders.
