What is considered Healthy Testosterone Levels?
Testosterone is “primarily a male sex hormone, as well as an anabolic steroid”.
Women also need testosterone in order to have functioning organs, a healthy sex drive, and for many other “critical for life” physiological functions.
—> Produced in the Testicles and Adrenal Glands
—> Healthy Level Range = 280 to 1,100 ng/dL
—> Produced in the Ovaries and Adrenal Glands
—> Healthy Level Range = 15 to 70 ng/dL
The amount of testosterone you have in your body is measured in nanograms per deciliter (ng/dL) of blood. The above levels are considered “Healthy” or “Normal” levels. The higher your testosterone levels are, the more Muscle you’ll be able to Build and Sustain.
Cortisol is NOT your Friend….
...Not when you’re trying to get Leaner, Stronger and Faster, anyway!
Cortisol is another steroid hormone that’s produced by your adrenal glands. This hormone is released when your body is under either Physical, Mental, Emotional, or Psychological Stress. You NEED Cortisol to live, but the main problem for you, when it comes to having too much Cortisol in your bloodstream is that too much of it will:
— Slow or Completely Stop Protein-Synthesis --- Protein-Synthesis = Muscle Repair & Muscle Growth
— Break Down Muscle (you’ll lose the muscle you've worked so hard to gain)
— Favor Central Fat Deposition (give you more belly fat)
— Increase Appetite and Food Intake - it does this by way of decreasing the adipostatic signal leptin, (and increasing) the orexogenic signal ghrelin.
— Lower Circulation Testosterone Concentrations
— Raise Blood Pressure & Lower Bone Density
All of these are NOT going to help you with your Getting Lean & Training Mean Goals.
Does D-Aspartic Acid really boost your testosterone levels?
There are a lot of Supplements found in various brands and formulas that claim to "boost natural testosterone levels”.
What is D-Aspartic Acid (DAA)?
D-aspartic acid (DAA) is one of two forms of the amino acid aspartic acid. The other form is L-aspartate. You can easily find DAA in Supplement formulas that claim to “boost testosterone levels” and you can also buy it by itself…in powder or pill form.
Does D-Aspartic Acid WORK?
Almost ALL of the peer-reviewed studies that have been done regarding DAA have been conducted on animals. This usually isn’t a problem, in the sense that animal studies “generally” have the same results as the studies done on humans. But with D-Aspartic Acid things get a little tricky!
For example, in one study, rats were given DAA and the results were very positive:
— The “amino acid (D-Aspartic Acid) induces the synthesis of testosterone…and it’s involved in steroidogenesis". Steroidogenesis = biological synthesis of steroid hormones. So YES! D-Aspartic Acid will boost your T levels…if you’re Master Splinter!
(if you got the “Teenage Mutant Ninja Turtles” reference…you're getting a virtual fist-bump right now!)
As far as the Human Research for DAA, the results are “still up in the air”. For example, one study states that:
— “after 12 days of D-Asp treatment, the levels of testosterone in the serum of the participants was significantly increased, compared with basal levels.”
So YES! it looks like (DAA) Works… Until you have a look at the following “Comprehensive Review” of the Research on (DAA) which states that:
— A “comprehensive systematic review, showed that exogenous D-Asp enhances testosterone levels in male animal studies…whereas the studies (using) humans yielded inconsistent results.”
In Conclusion…D-Aspartic Acid (DAA) does work for rats, but it does NOT work the same for humans! So the question you’re probably asking is - should you use DAA as a testosterone boosting supplement?
Having a clear view now and seeing that the research is so scattered and there are so many other test boosting supplements that are proven to actually work, what would your answer be? What are your thoughts on DAA?
