Three grams D-aspartic acid raises testosterone levels by a third
Taking a supplement that is based on an amino acid found naturally in the body increases the production of the messenger hormone LH and the muscle building testosterone in the pituitary gland and the testes, by enhancing the cellular production of signal molecules that control the secretion of LH and testosterone.
D-aspartic acid is formed when the enzyme aspartate racemase converts L-aspartic acid into D-aspartic acid in the testes and other glands. This amino acid plays a key role in the manufacture of sperm cells and sex hormone. That’s why the Italian pharmaceuticals company Pharmaguida markets the amino acid in products like Dadavit, which is aimed at infertile men.
The researchers gave a couple of dozen men aged between 27 and 37 a daily dose of 3.12 grams D-aspartic acid for twelve days consecutively. Twenty other men were given a placebo. The testosterone level in the subjects that received the supplement had risen by 33 percent after the twelve days, as the table below shows.
The Italians studied the mechanism involved using rats. The rats were given the amino acid in their drinking water. The figure below shows the effects of twelve days of supplement administration on the concentration of the amino acid in the pituitary and the testes of the rats.
In the pituitary gland, D-aspartic acid increased the concentration of cGMP. cGMP is a signal molecule – or a second messenger – that transfers messages in the pituitary cells from other messenger hormones to the DNA. More cGMP means more LH. In the testes D-aspartic acid plays a similar role with the signal molecule cAMP, via which D-aspartic acid raises testosterone secretion.

I love how AR says this:
TST PowerCell is another supplement that contains this ingredient, this time at less than 600mgs/capsule, roughly 1/5th of an effective dose.
Yes, AR, 600mg is 1/5th of an effective dose, but as you said its PER CAPSULE, with a recommended dose of 4 caps per day its much closer to that 3gs.
Also TST Powercell is not sold by itself, only in combination w/ other products and when bought with Hard-FX your getting more then 3.1gs of DAA per day.
