Prohormone & Supplement Ingredients:

D-Aspartic Acid (DAA)

Aspartic acid is a non-essential amino acid, meainingit can be synthesized by th body. Aspartic acid is found in:

Animal sources: luncheon meats, sausage meat, wild game

Vegetable sources: sprouting seeds, oat flakes, avocado, asparagus[citation needed], young sugarcane, and molasses from sugar beets.

Dietary supplements, either as aspartic acid itself or salts (such as magnesium aspartate)

The sweetener aspartame (NutraSweet, Equal, Canderel, etc.)

D-Aspartic Acid (DAA - one of the two form of Aspartic Acid) is present in neuroendocrine tissues of humans and plays a role in the synthesis of both LH (Luteinizing hormone, also known as lutropin) and testosterone.

Supplementation with 3 grams (3,000mg) per day resulted in a 33% testosterone increase of 33%. While this might seem impressive, a 33% increase is unlikely to provide any real training boost or visible results. Added to this is that the majority of supplement containg DAA and claiming to be the 'next best thing' typically have a much less than 3g dose.

The straight scoop seems to be that as far as a test booster, DAA isn't that great. You have to take a huge dose for a relatively small effect.
