D-Aspartic Acid (DAA) by ASP Nutrition is a high-quality natural testosterone booster on the market. The body can produce DAA from the nonessential amino acid L-aspartic acid (the dietary form of aspartic acid). Aspartic Acid is a physiological amino acid occurring principally in the pituitary gland, hypothalamus, and testes. It is a very potent sexual stimulator and can be used to help enhance libido, duration of intercourse among other qualities in the bedroom. D-Aspartic Acid can also enhance Nitric Oxide levels and can induce the elevation of neurotransmitters such as dopamine and GABA, which are thought to be responsible for memory enhancement, anti-depressant, and nootropic effects.
D-Aspartic Acid has been shown that it raised testosterone levels in healthy adult males an average of 42% in as little as 12 days, with some experiencing a boost of over 50% in that same period of time. This study also indicated that testosterone levels were still elevated 3 days after the discontinuation of D-Aspartic Acid, which indicates that it builds up over time, and then slowly decreases after supplementation is stopped.
When the team at Genesis Nutrition are very pleased with the results when using DAA. We found the libido was through the roof, strength was definitely improved, mood was great and we saw improvements in muscle size and firmness. All around, we found it to be an excellent product that Genesis Nutrition highly recommends!
