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
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 was determined.
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.
Tested D-ASPARTIC is comprised of 100% D-Aspartic Calcium Chelate. No cheap fillers are added.
Ensure that you increase your protein intake to support this new muscle growth.

This stuff is great, I feel really good on it. Its been 2 months, and I plan on continuing. I only have one complaint, and its that after 3 weeks it caused me to break out in acne. I don't usually have this problem ever, but i know with Test booster this could occur. But it was extensive and only lasted about a week and half. Naturally your body adjusts to the product and skin cleared up. BUT! that is also evidence that this stuff is stimulating test production.
J'ai dans la cinquantaine et ce produit augmente mon endurance et ma force, c'est un bon produit pour augmenter sa testostérone.
Good not great, gained a bit of strength and less tired during the day. Tested Nutrition Citrulline is much better .... for me.
been taking it now for about 3 weeks noticed strength gains after about 4 days. Increase my protein intake and gained 5-7 pounds so far...no way this stuff is legal here or in europe
