What is D-Aspartic Acid (DAA)?
D-Aspartic Acid is one of the enantiomers of the amino acid known as Aspartate, where the common dietary enantiomer is L-Aspartate. L-Aspartate is a non-essential amino acid and can be incorporated into protein structures, although D-Aspartate is not commonly associated with protein structures. D-Aspartate has been found 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. Cycling of D-Aspartic Acid is recommended and the most effective means of use.

Muscle Empire D-Aspartic Acid (unflavored) is a pure form powder with no excipients or fillers, available in multiple sizes.

    My recovery from heavy training has improved dramatically. Very little soreness after a heavy session. Quick recovery. I would have to say this product is for real. And the research seems to back it up. Ive recommended it to a few associates.

    After a week of use (1/2 teaspoon leveled 2 times a day) I will say it works, After years of Testosterone supplements (injected) for a career of mixed martial arts, I have some idea about the levels of test needed to really get a big boost in aggression and performance.
    Thus I would compare use of this product to 1/8th of a 250ml testosterone injection in effect.
    If you never used steroids before this product will be amazing (if your over 40) if you have used steroids before this product is... noticeable but not anything close to the real gear.
    as for the estrogen effects of it... firstly your body makes estrogen out of unused testosterone. estrogen is not manufactured in your body from scratch (first fact) so the with even a 40% increase in test levels from this product you can very easily burn off (use in muscular development) that extra test with little remaining to convert to hated estrogen.
    therefore I do not think any anti-estrogens are needed for this very small rise in test levels, remember that steroids boost your test levels several hundred or even thousand times more than normal and anti estrogen is only needed at the end of a cycle and only to get your body back to normal test levels, so a 40% increase is really not much and it wont build big muscles like steroids do, but it will make you more horny and a bit more aggressive, use that aggression to lift more weights and you will build more muscle but only at your normal growth rate.
    so ending I will say its a good product for old bastards like me who don't want to loose years of trained muscle mass with old age.
    its not steroids.
    you wont blow up and dominate the octagon with this product.
    but you will benefit from it if your over 40.
    and stop worrying about estrogen effects from it, just work out hard every day and you will be fine.
    also note that alcohol (even as little as one beer a day) will contribute to far FAR greater testosterone conversation (in to estrogen) than a 40% test increase will. avoid the drink and you will avoid the man boobs!
