Description

Tested Nutrition D-Aspartic Acid (DAA)

Clinically Proven to Increase Testosterone by 50% In 12 Days!

I just wanna add my 2 cents before you go any further. This product works and should be cycled 12 days on 12 days off don't be tempted to go beyond 12 days without a break

Recent research has shown the D-aspartic acid serves as a specialized neurotransmitter in parts of the nervous system involved in hormone production. It has been shown to stimulate the release of (LH) Luteinizing Hormone and (GH) Growth Hormone from the pituitary gland. Furthermore, it has also been demonstrated to have a direct stimulating effect in the testes upon testosterone production.

In Males LH acts on the interstitial cells (also known as Leydig cells) of the testes stimulating them to synthesize and secrete the male sex hormone, testosterone.

Growth hormone (GH) is a protein-based peptide hormone. It stimulates growth, cell reproduction and regeneration in humans and other animals. Growth hormone is a 191-amino acid, single-chain polypeptide that is synthesized, stored, and secreted by the somatotroph cells within the lateral wings of the anterior pituitary gland

Background

D-aspartic acid is an amino acid present in neuroendocrine tissues of invertebrates and vertebrates, including rats and humans. Here we investigated the effect of this amino acid on the release of LH and testosterone in the serum of humans and rats. Furthermore, we investigated the role of D-aspartate in the synthesis of LH and testosterone in the pituitary and testes of rats, and the molecular mechanisms by which this amino acid triggers its action.

Methods

For humans: A group of 23 men were given a daily dose of D-aspartate for 12 days, whereas another group of 20 men were given a placebo. For rats: A group of 10 rats drank a solution of either 20 mM D-aspartate or a placebo for 12 days. Then LH and testosterone accumulation was determined in the serum and D-aspartate accumulation in tissues. The effects of D-aspartate on the synthesis of LH and testosterone were gauged on isolated rat pituitary and Leydig cells. Tissues were incubated with D-aspartate, and then the concentration (synthesis) of LH and cGMP in the pituitary and of testosterone and cAMP in the Leydig cells was determined.

Results

In humans and rats, sodium D-aspartate induces an enhancement of LH and testosterone release. In the rat pituitary, sodium D-aspartate increases the release and synthesis of LH through the involvement of cGMP as a second messenger, whereas in rat testis Leydig cells, it increases the synthesis and release of testosterone and cAMP is implicated as second messenger. In the pituitary and in testes D-Asp is synthesized by a D-aspartate racemase which convert L-Asp into D-Asp. The pituitary and testes possesses a high capacity to trapping circulating D-Asp from hexogen or endogen sources.

Conclusion

D-aspartic acid is a physiological amino acid occurring principally in the pituitary gland and testes and has a role in the regulation of the release and synthesis of LH and testosterone in humans and rats.

Great product

I have always been a fan of DAA , only “test” booster I’d even recomend, when cycled properly and combined with a good diet regiment this little thing can do wonder. Got back into powerlifting after taking a long break due to a shoulder injury. Roughly 1-2 months and manage to bench 325 with ease … not gonna credit solely this product but I know it plays a role in my recovery and strenght !!

DAA

I have used this product several times over the past few years and found that when I get into my resistance training phase that my strength and stamina definitely improves. This is an important part of my training especially at the age of 69. Resistance training and added strength and stamina is important for the other activities I participate in, such as cycling mountain hiking and kayaking.

Great product

I've seen great results in many ways by using this product. I typically do 2 months on then 2 weeks off myself and have been taking DAA for almost a year now with no noticeable side effects. Great price, great gains, I really can't complain. Highly recommend! (Male aged 33).
