D-Aspartic Acid is an ingredient that’s been showing up in testosterone supplements for a while now.
How does it boost testosterone?…Is it that effective?…What’s the right dosage?…How long should I use it?…Is it even safe?
All good questions. Our aim with this article is to answer these questions and give you a better idea of what benefits D-AA is giving you, and whether there are any negative aspects.

D-Aspartic Acid – D-AA – What is It?
It is one form of the amino acid, Aspartic Acid. The other form is known as L-Aspartate, which may sound like it should have the same properties and benefits – but it doesn’t.
The effects of D-Aspartic Acid are quite unique to it.
What Does It Do?
D-aspartic acid boosts the natural production of testosterone, and it does it quite efficiently compared to many ingredients used for similar purposes.
In fact, D-AA can increase testosterone production by nearly 50% in under 2 weeks of supplementation.
One reason for this is that it interacts with not one, but two points of the testosterone production process. In addition, it boosts another anabolic hormone: growth hormone.
Here are those processes summarized:
- It works in the brain to increase two hormones responsible for signalling the testicles to manufacture testosterone; Luteinizing Hormone and Follicle Stimulating Hormone
- It accumulates in the testicles to help directly manufacture even more testosterone
- Back to the brain, and D-AA stimulates the release of more Growth Hormone Releasing Hormone, leading to further enhancement of that anabolic pathway
What Does This Mean for You?
The biggest implication of the above is that D-AA will act fast.
During a study involving men, it took only 12 days for their testosterone levels to be increased by an enormous 42%.
Therefore, it has been demonstrated that there can be a fast and steep increase in testosterone after supplementation with D-Aspartic Acid.

Who Should Use D-Aspartic Acid?
This is one testosterone booster that can be used by both athletes and people with low levels of testosterone.
For the athlete (weight lifter, endurance, team sports), testosterone is a valuable commodity as regular intense exercise can deplete its levels. D-AA will work over a two week period to really bolster the production.
For guys with low natural levels of testosterone, will be effective for a little longer to help optimize production.
How Do You Get The Most from D-AA?
In our experience, the best way to use D-AA is as part of a combined supplement that includes several other testosterone boosting ingredients.
The reason for this is because the D-Aspartic Acid will act to kick-start testosterone production over a very short period of time, leaving the other ingredients to take effect over a longer term.
Cycle Length, Dosage, Safety
It appears from research that between 1500mg and 3000mg a day is safe to use. Long term dosage will result in little extra benefit over the initial 2 week boost, though there are no safety concerns.
No side effects were experienced by test groups and we have not noticed any from long term usage within the above dosage spectrum.
As part of a combined supplement with other ingredients, the cycle length for the D-AA will obviously be the same as all the rest. The initial 14 day spike will be useful for the athletic users, however the low testosterone users will get more out of the longer cycle.
Usually, capsule supplements are cycled for 8 to 12 weeks (perhaps even 16 weeks) with a two week break before repeating the whole cycle.
There are several options available at the moment.
The supplements we would recommend all contain a great dose of D-AA, along with other proven T boosters.
The best product currently is TestBoost.
It contains an excellent formula, and the ingredients are perfectly matched to produce a staggered, prolonged increase in testosterone and other anabolic hormones.
