What Is D-Aspartic Acid (DAA) Powder?
D-Aspartic acid is an enantiomer of the amino acid Aspartate. The common dietary enantiomer of Aspartate is L-Aspartate. L-Aspartate is a non-essential amino acid and can be incorporated into protein structures, although D-Aspartate is not associated with protein structures, rather with hormone regulation. Through research, D-Aspartate is believed to be a constituent of human cartilage, enamel, and can be accumulated in the brain as well as being a constituent of blood cell membranes.† D-Aspartic acid shows promise in increasing nitric oxide levels. Continuous supplementation of D-Aspartic acid may only provide temporary increases in test levels for healthy men. It is recommended to cycle D-Aspartic acid and is the most effective means of use.† 

D-Aspartic (DAA) Benefits & Uses May include:

  • Supports Nitric Oxide Levels†
  • Supports Improved Libido†
  • Healthy Testosterone Levels†

How Does D-Aspartic Acid (DAA) Powder Work?
DAA, one of two forms of aspartic acid, is an amino acid found in both the central nervous system as well as in reproductive tissues. Unlike its L-Aspartic Acid counterpart, DAA is not used to make proteins. It is suggested that DAA is responsible for developing the nervous system as well as hormone regulation. Concerning hormone regulation within the endocrine glands, DAA releases prolactin from the anterior pituitary gland; in the posterior pituitary gland, it modulates vasopressin and oxytocin and suppresses the secretion of melatonin in the pineal gland. Where the adrenal gland is concerned, it regulates testosterone production. DAA accumulates in neuroendocrine tissue such as the pituitary gland, pineal gland, and reproductive organs, where it works as an excitatory compound to stimulate the release of hormones.[1]

    Great with Citruline

    DAA is essential when you're taking Citruline to produce NO. I didn't know this and wasn't taking it. Have noticed a huge difference in my workouts since adding DAA to my preworkout concoction. Definitely recommend taking along with citruline and L arginine.

    YES this does WORK

    Not to get too graphic here (Ladies you may want to close your eyes when reading further) but my balls are hanging much heavier that the nut sack skin on the upper portion is starting to wrinkle from the additional weight that my balls have gained since taking 4-5g of DAA 2 and a half weeks ago. I can actually contract my balls to go up and down bouncing easily (Something that I have had difficulty in the past to do). I am blowing much more of that white stuff to the point that it actually shoots out strongly about 5 or 5 times and the erection is stronger. I am taking this with Agmatine (3g at nighttime) to boost LH and GH and I definitely feel these chemicals complimenting each other big time. This stuff is SERIOUSLY underrated.

    We will wait and see if over time it helps with T levels

    Relatively tasteless with coconut milk, and for the price it can't be beat. I like this brand and I will be sticking with Hard Rhino.
