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,
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
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.
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
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.
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.
