The Ingredients

Insane Pump
Neuro Focus
ElEvate endurance
HydroPrime HydroPrime® is a stable form of Glycerol that delivers a high Glycerol yield, without the clumping or gritty consistency. HydroPrime® features an industry-leading Glycerol yield per gram of powder, allowing the user to get more Glycerol out of less powder.
L-Citrulline Citrulline is one of the three dietary amino acids in the urea cycle (the other two are L-arginine and L-ornithine). Taking citrulline increases plasma levels of arginine and improves the ammonia recycling process and nitric oxide metabolism. Consequently, citrulline may be useful in situations in which nitric oxide is relevant, such as athletic performance, vascular health, and erectile dysfunction. 
Nitrosigine Nitrosigine® is a patented complex of Bonded Arginine Silicate that is scientifically engineered to deliver benefits essential to peak sports performance. Nitrosigine is a powerful and safe non-stimulant ingredient that has been clinically studied for safety and efficacy in 30 studies. The use of Nitrosigine has been shown to promote nitric oxide (NO) production for improved blood flow, focus, and energy.
Pine Bark Extract Pine bark extract is a source of pycnogenol which enhances nitric oxide production and increases blood flow. 
VasoDrive-AP Derived from milk protein through a proprietary enzymatic process, VasoDrive-AP occurs in very small amounts in casein as tripeptides, which are three specific amino acids joined together in a precise configuration. It works to support blood pressure already within a healthy range by inhibiting an enzyme that leads to the constriction of blood vessels.
CognatiQ CognatiQ® is a patented coffee fruit extract that has been clinically shown to boost brain-derived neurotrophic factor (BDNF), increase brain connectivity, and improve daily, cognitive performance.†
Lions Mane The lion's mane mushroom (Hericium erinaceus) is an adaptogenic mushroom that has long been used in alternative medicine. The lion's mane mushroom has many benefits including reducing mental fatigue, supporting energy levels, and promoting brain health and cognitive function.
N-Acetyl-L-Tyrosine Tyrosine helps increase dopamine production for improved mood when under stress. The N-Acetyl-Tyrosine form improves absorption over L-Tyrosine and has a greater effect.
AstraGin Taking AstraGin® on a regular basis supports the body's natural ability to absorb more nutrients, limit toxins from entering the body, provide a favorable eco-environment for microbiota, and support immune cell population and vitality.
Beta-Alanine Beta-alanine is one of the building blocks of carnosine, a compound that helps to buffer acid in muscles to increase physical performance.
Betaine Betaine’s function is in the methylation of the amino acid homocysteine to form methionine, which increases creatine production in the body, as well as increases protein synthesis. Betaine also supports healthy homocysteine levels, and high levels have been shown to impair insulin signaling, which can interfere with muscle growth and fat loss.
Taurine Taurine is an amino acid found in high concentrations in the brain where it helps with the movement of potassium, sodium, calcium, and magnesium in and out of brain cells, supporting central nervous system activity. It also has the ability to enhance muscle contraction and delay muscle fatigue
