D-aspartic acid (D-AA): is an amino acid regulator of testosterone synthesis and may act on a stimulatory receptor.
Arginine alpha-ketoglutarate (AAKG): is a salt of the amino acid arginine and alpha-Ketoglutaric acid. Nitric oxide supplements usually contain arginine alpha-ketoglutarate, which purportedly increases and maintains a high level of nitric oxide in muscles. In theory, the production of nitric oxide from the supplemental arginine promotes vasodilation (dilation of blood vessels, which in theory may make you look vascular [veiny]), which increases blood flow, oxygen transport, and delivery of nutrients to skeletal muscle during resistance training. This purportedly results in dramatic increases in muscle size and strength.
Caffeine: increases alertness, sharpens focus, improves mood, improves tolerance for pain caused by exercise, helps burn fat, and helps athletes do more work for longer periods in the gym and in sport.
Agmatine Sulfate: works to provide the following potential benefits: Improved muscle pumps via the inhibition of nitric oxide synthase (NOS). Better intra-workout energy.
Beet Root Extract: has been suggested to enhance exercise performance, endurance, and lessen fatique. All of this can help increase muscle strength, muscle growth, and muscle endurance.
L-Tyrosine: is an amino acid that is used to produce noradrenaline and dopamine.
L-Norvaline: works by inhibiting arginase production, allowing you to blow past that ceiling and keep producing nitric oxide throughout your workout. This makes your pumps stronger and longer lasting.
Yohimbe: dilates the blood vessels and can lower blood pressure and help with weight loss.
Huperzine A: is an alkaloid extracted from a club moss called Huperzia serrata. Huperzine A
has many neuroprotective and nootropic properties.
