L-Tyrosine
1,000 mg
L-tyrosine is an amino acid that serves as a precursor to dopamine and norepinephrine.
SenActiv®
50 mg
SenActiv® is a patented adaptogenic complex that helps accelerate muscle recovery during/after intense exercise.
ElevATP®
150 mg
elevATP® stimulates your body’s endogenous production of adenosine triphosphate (ATP), the veritable energetic currency of cells
BioPerine®
5 mg
BioPerine® is a standardized extract of black pepper fruit enriched with piperine, a compound that helps your body absorb and utilize active ingredients.
Huperzine-A
100 mcg
Huperzine-A is a natural nootropic that improves cognitive function by reducing the breakdown of acetylcholine.
L-Citrulline Malate (2:1)
8,000 mg
L-Citrulline malate is an amino acid that enhances physical endurance due to its role in the synthesis of nitric oxide (NO) . [1]
When nitric oxide production increases, blood flow improves, allowing nutrients and oxygen to replenish muscle tissue more efficiently. This translates to greater muscle pumps and heightened energy levels.
Numerous studies have demonstrated the performance-enhancing effects of L-citrulline malate such enhancing strength, muscle power output, anaerobic and aerobic capacity [2, 3, 4]
Additionally, studies indicate that L-Citrulline Malate reduces muscle soreness and enhances immune responses during the post-exercise period, supporting recovery from physical training [5].
Beta-Alanine
4,000 mg
Beta-alanine is an amino acid that functions as a precursor to carnosine, a molecule that accumulates in skeletal muscle tissue, where it plays a crucial role in buffering the acid produced during intense physical exercise.
Supplementing with Beta-alanine has been shown to increase muscle carnosine levels, which are quickly depleted during intense exercise [6, 7].
Research shows that supplementing with Beta-alanine can significantly improve overall exercise capacity including maximal strength and power output, particularly in exercises requiring sustained maximal effort[8]. strength [9]
Beta-alanine supplementation may also increase lean muscle mass [10] and delay the onset of neuromuscular fatigue [11, 12]
BetaPure™ Betaine Anhydrous
2,500 mg
Betaine, also known as trimethylglycine, plays a role in various physiological processes, primarily as an osmolyte (helping cells maintain fluid balance) and a methyl donor (assisting in biochemical reactions). Betaine supplementation has shown promise in improving muscle endurance and enhancing strength and power in trained individuals [13, 14, 15].
While the mechanisms are not fully understood, Betaine supplementation may promote athletic performance through regulating cellular hydration, supporting creatine biosynthesis and playing a role in ATP (energy) production. [16]
Taurine
1,300 mg
Taurine is one of the most well studied performance aids offering diverse benefits for athletes and active individuals. Evidence indicates that adequate taurine levels are pivotal for central nervous system (CNS) function and may help prevent fatigue during arduous exercise. [17]
Taurine has been shown to be effective in enhancing both aerobic and anaerobic performance while also supporting recovery from exercise. [ 18, 19]
Several studies have demonstrated that taurine supplementation can help delay time to exhaustion and decrease rate of perceived exertion making it an important ingredient for intense physical activity. [20, 21]
L-Tyrosine
1,000 mg
Increasing tyrosine uptake may positively influence neurotransmitter-related psychological functioning. Research shows that supplementing with L-tyrosine can significantly enhance cognitive performance, especially under acutely stressful situations (such as intense training) [22].
L-Tyrosine has also been shown to improve “cognitive flexibility,” meaning it can help you adapt to changing cognitive demands without letting extraneous thoughts take over [23].
SenActiv®
50 mg
The adaptogens that comprise SenActiv® are Panax notoginseng root and rose hips (Rosa roxburghii). The notoginseng in SenActiv® is highly concentrated in notoginsenoside R1, a beneficial compound that helps accelerate muscle recovery during/after intense exercise.
Likewise, the rose hips provide several ginsenoside-like molecules that provide synergistic recovery-enhancing effects with ginsenoside R1 [24].
These phytonutrients are suggested to work by bolstering a cellular "cleaning" process known as autophagy, particularly in skeletal muscle cells [25, 26, 27].
ElevATP®
150 mg
ElevATP® is a clinically researched combination of “ancient peat” (fossilized plants) and apple skin extracts. Using innovative biotechnology, elevATP® stimulates your body’s endogenous production of adenosine triphosphate (ATP), the veritable energetic currency of cells.
By boosting ATP production, ElevATP® can help promote athletic performance (e.g. max strength) and improve body composition [28, 29]. ElevATP® is also a fast-acting ATP booster that starts working from the very first dose [30].
BioPerine®
5 mg
BioPerine® is a patented black pepper (Piper nigrum) fruit extract standardized for its piperine content. Piperine is a natural alkaloid known for its “bioenhancer” properties, improving the bioavailability of molecules that are typically poorly absorbed or extensively metabolized in the liver [30, 31].
Huperzine-A
100 mcg
This natural nootropic is known for inhibiting acetylcholinesterase, thereby increasing acetylcholine levels, a neurotransmitter vital for learning and memory.
A recent research review contends that huperzine-A, a constituent of the Chinese folk medicine Huperzia serrata, is a good candidate to improve cognitive function and may help boost memory [32].
