There are many conflicting studies on DAA. Some show amazing results in raising natural test, and others don’t. A review on D Aspartic Acid is in order! Why all the confusion? Here is why:

Although everyone uses the term D-Aspartic Acid they are using sodium (Na+)D-Aspartate in their experiments! All studies using Na+ D-ASpartate result in increased Luteinizing Hormone (LH) production and increased testosterone (T) production, while the studies using D Aspartic Acid show no increase in either hormone! This glitch in research documentation has literally permitted the supplement industry to accept the wrong version of the chemical and now virtually every product is using D Aspartic Acid (ineffective) instead of Na- D Aspartate (highly effective)

For example this study used Na+D Aspartate but refers to it as D Aspartic Acid in the actual write up: “ The role and molecular mechanism of D-aspartic acid in the release and synthesis of LH and testosterone in humans and rats”http://www.rbej.com/content/7/1/120

This study dosed 3.12 grams of sodium-d-aspartate to adult males (27 to 37 yrs old) for 12 days resulting in a 42% increase in average testosterone levels (1). This was administered on an empty stomach before breakfast. These may not seem like huge increases in testosterone but these are controlled, scientific results in normal healthy men. Evidence exists in the literature that shows D-aspartic acid to be more effective at increasing LH levels in animals that have been castrated suggesting that D-aspartic acid may be even more effective in hypogonadal males or those whose natural production may be suppressed following a steroid cycle.

In the Figures below It is demonstrated that In rats, Na+D-ASpartate causes a 33% increase in LH and a 50% increase in testosterone,  

Na+D aspartate


Na+ D-Aspartate works by causing increased activity of the cGMP second messenger system in the brain, thus helping LH release. The Na+D-Aspartate causes the cAMP second messenger system in the testes to increase the transport of cholesterol into the leydig cells. Testosterone, and all human steroids are manufactured from cholesterol. That is why increasing this transportation is the most important way to increase testicle functioning. The Leydig cells are the cells that make Testosterone.


Most of the DAA products on the market are NOT using Na+ D Aspartate. They contain D Aspartic Acid. Since the standard DAA is known and accepted, it is in demand. The companies that manufacture the raw ingredients have increased production of DAA and there is more competition within this industry for DAA sales. This had driven the price down. Basically it is cheap to buy raw DAA in large quantities. Na+ D Aspartate is not in demand because very few brands are using it in their products. Na+ D Aspartate is more than 5 times the price of D Aspartic Acid. While I certainly can’t say that the big brands are aware of that they are using the wrong chemical. I can say that they are saving a lot of money by using DAA instead of Na+ D Aspartate. Valhalla-Labs.com products only contain the best and most effective ingredients. The ToddLeeMD.com / Thor’s Hammer combo pack contains 3000mg per serving of Na+D Aspartate!

The body uses Vitamin D to transport the Cholesterol also. I added Vitamin D to Na+D-Aspartate when I designed ToddLeeMD.com Test Booster.  This makes the Thor’s Hammer Combo pack the best natural test booster or way to increase testosterone on the market! It would also help restore function to normal when used on cycle or post cycle
