D-Aspartic Acid is an amino acid that is a regulator of testosterone synthesis. What differs other D-Aspartic Acid products from APS’s is that APS uses N-Methyl-D-Aspartic Acid which is a more potent version that our bodies can uptake more efficiently.
Simply put, it works better.
NMDA will deliver a potent combination of testosterone, growth hormone, IGF-1, and IGF-2. Thus causing you to increase lean muscle mass.
