D-Aspartic Acid and Testosterone

One of the key amino acids when it comes to gaining muscle and boosting testosterone levels is D-Aspartic Acid.

Clinical proven to raise T-Cell count, and even fertility. DAA is a must have addition to anyone who’s looking to make serious changes in their lifestyle.

This is a nutrient that works directly with your brain to create major hormone releases throughout your system which helps increase:

  • Muscle Size and Strength
  • Testosterone Levels
  • Growth Hormone Production

The amino acid takes on a key role when it comes to testosterone production, it helps your brain create the all important Luteinzing Hormone (LH) which is the necessary precursor to testosterone and growth hormone production.

Not many people know about the power packed into this complicated amino acid, but the evidence is there, and anyone uses TestoFuel will tell you that it definitely makes a difference to their overall workouts.

Why you need D-Aspartic Acid in your diet

It all sounds well and good, but don’t we get enough of this stuff naturally?


Although you can find amounts of D-Aspartic Acid in your diet (especially if you’re a meat or cheese eater), clinical trials have shown that testosterone levels greatly increase after introducing oral supplementation.

If you want to get better results out of your workouts, supplementing DAA is a great way to make them happen.

In a study involving regular supplementation of D-Aspartic directly after meals [1] was seen to greatly increase the amount of Luteinzing Hormone (LH) produced in the body, and by extension, the amount of testosterone created.

Whereas more impressively supplementation of D-Aspartic Acid for a period of 90 days was seen to raise serum testosterone in subjects by an average of 30 – 60%. Seminal count and mobility also improved, with both having an average increase of 60 – 100%. [2]

How we make that happen

The last thing you want is your muscles not being able to keep up with your motivation. That’s why TestoFuel has crammed 2300mg of D-Aspartic Acid into every daily serving of our testosterone booster.

With daily supplementation, you’ll start enjoying the effects of the amino acid and really appreciate the long term benefits.
