D-Aspartic acid increases natural testosterone production and release, by increasing the release of gonadotrophin and luteinizing hormone. DAA triggers the release of the GnRH (gonadotropin-releasing hormone that informs the pituitary that testosterone concentration in the blood is falling), oxytocin and vasopressin (the “love hormones”), the luteinizing hormone (LH) and the growth hormone (GH) from the neuroendocrine axis (the hypothalamus and the pituitary gland), and testosterone from the testes. The pituary gland and the testes have the ability to trap circulating d-aspartic acid.
Natural increased release of GnRH and LH resulting in increased testosterone levels can be observed from puberty only to mid-twenties. Men after 30 experience lowered testosterone levels, which leads to a lowered libido, increased body fat levels, problems with sleep, decreased recovery ability, and decreased ability to build up muscle. In other words, DAA supplement causes you body to produce more testosterone as if you were younger and helps to get rid of the above mentioned symptoms. The deciding advantage of d-aspartic acid over direct testosterone supplementation (e.g. with steroids) is that the testosterone is produced by your body and not delivered from outside, which could interfere with body’s own testosterone production.
Has D-Aspartic Acid undergone clinical trials on humans?
Unlike other testosterone boosters, there is a scientific confirmation that DAA supplements increase testosterone levels by humans. A recent study has been conducted on both the human volunteers and on rats. 23 men between 27 and 37 have taken a DAA supplement for 12 days. The testosterone and LH levels have been significantly increased in comparison with a control group who took placebo (a solution of salt). The increase of luteinizing hormone was 33%, the increase of testosterone – a massive 42% in only 12 days! Similar results have been observed with rats. An elevated level of testosterone in blood remained even three days after suspension of the treatment, probably due to the concentration of d-aspartic-acid trapped in tissues. It is noteworthy that this clinical research has been conducted on healthy men with normal testorone levels, not hypogonadal men.
Who should use it?
Recommended for Males 21 & over. Studies have only been conducted on males & at this stage is not recommended for female supplementation.
How do you use it?
Testosterone increasing benefits have been found with taking 3000mg (3g) once daily. How much should I use?
D-Aspartic Acid, like all Testosterone Booster, should be cycled. The two main cycle lengths seem to be:
- 12 days on, followed by 7 days off; repeat if desired
- 3 weeks on, followed by 2-4 weeks off; repeat if desired
The former was used in the lone human study, the latter has been used with success anecdotally. Whether cycling is needed with D-Aspartic Acid is unknown but currently prudent.
