It’s no wonder it’s considered the King of the natural hormones produced by your body. As any 5%er most likely knows, testosterone has a range of functions in the body. These include key roles in stimulating muscle growth, enhancing sex drive, and improving stamina.

Yet, there’s a problem. As we start getting older, our natural levels get progressively lower. In this case, beginning to get older means your mid-twenties.

One serving of 5% Core D-Aspartic Acid provides 3,120mg per serving. This potent ingredient is one of the most effective natural test boosters available.

Did you think we stopped there? You know us better than that. We also added 200 mg of DIM. What’s better than increasing testosterone and controlling estrogen?

The great thing about Core D-Aspartic Acid is you can stack it with our other test boosting formulas, namely Core ZMA. Combining these two gives you a powerful testosterone-boosting stack. Based on your goals, you can build your stack from there.

Let’s check out the ingredients.

This is an essential amino acid that occurs naturally in the testes, hypothalamus, and pituitary glands. There’s one main clinical study that showed an increase in the body’s levels of testosterone using this ingredient. It was conducted on 23 male test subjects. Each test subject was given one 3-gram dose per day. After 12 days, testosterone levels of the test subjects increased on average by 42%. That’s one heck of an increase!⁽¹⁾

You want estrogen under control when your testosterone levels increase. DIM, or 3,3'-Diindolylmethane, does this by blocking aromatase. This is the enzyme that converts excess levels of testosterone into estrogen. This, of course, leads to unwanted side effects such as bloating and fat gain.⁽²⁾

If you want the most out of your program, you want the most out of your body’s natural testosterone production and the place to start is 5% Nutrition Core D-Aspartic Acid.
