HOSSTILITY delivers two premium and powerful ingredients that work synergistically to target multiple nitric oxide (NO) pathways, creating the ultimate matrix for a complete, all-out pump experience unlike anything else.

PURE L-CITRULLINE: The HOSSTILITY formula delivers a powerful 6-gram dose of vegan, fermented ultra-pure L-citrulline. L-citrulline is readily absorbed and converted to L-arginine in the body, leading to increases in both L-arginine and nitric oxide. Increased nitric oxide promotes vasodilation, or the widening of blood vessels, facilitating greater blood flow and higher nutrient and oxygen delivery to working muscles during exercise for powerful muscle pumps.

NO3-T ARGININE NITRATE: Cutting-edge patented NO3-T® Nitrate Technology fuses nitric acid with L-arginine for a powerful pump-enhancing ingredient. Combining these two highly effective, scientifically researched ingredients has been shown to promote greater plasma nitric oxide levels than either alone. Research shows nitric oxide bioavailability is also enhanced when combining L-arginine with L-citrulline. HOSSTILITY taps into these ingredient synergies, amplifying the power of L-citrulline with an added 2 grams of NO3-T Arginine Nitrate to support intense, longer-lasting muscle pumps.


HOSSTILITY features three scientifically validated ingredients—PeakO₂, creatine, betaine—designed to enhance endurance and promote muscle- and strength-building by supporting workout performance.

PEAKO₂: PeakO₂® is a powerful complex of six adaptogenic mushrooms scientifically shown to help the body adapt to and overcome physical and mental stress when performing intense exercise. By improving oxygen utilization in the body while decreasing lactate build-up in muscles, PeakO₂ supports increased strength, power, and endurance, helping you train harder for longer. HOSSTILITY delivers a researched 2-gram dose designed to fuel all-out workout performance, from start to finish.

CREATINE MONOHYDRATE: Creatine monohydrate improves your body’s ability to quickly replenish and recycle adenosine triphosphate (ATP), the energy currency of muscle cells. It also helps pull more water into muscle cells, supporting improved cellular hydration and a pumped effect. HOSSTILITY features a scientifically researched 3-gram dose of creatine monohydrate to support lean muscle, strength, and endurance increases.

BETAINE ANHYDROUS: Betaine has been shown to enhance strength, power, and muscle endurance. HOSSTILITY features a scientifically studied 2.5-gram dose to support your workout performance. Like creatine, betaine is also osmoregulatory, helping regulate water balance and promote cell hydration.


HOSSTILITY delivers six research-backed multitasking brain optimizers to support a state of peak mental performance. Formulated with high-potency, scientific range dosages of ingredients, this advanced synergistic matrix helps get you firing on all cylinders, promoting optimal brain chemistry for enhanced focus, energy, intensity, and motivation as you train.

ALPHA-GPC: Alpha-GPC, or Alpha-Glyceryl Phosphoryl Choline, is a powerful compound that enhances choline levels in the brain. Unlike other choline-containing compounds, Alpha-GPC is highly bioavailable and easily crosses the blood-brain barrier, where it quickly takes action to increase circulating acetylcholine (ACh) levels within the central nervous system (CNS). Alpha-GPC supports cognitive performance, delivering enhanced focus. Research has shown that supplementing with 600 mg of Alpha-GPC improves power output.

TEACRINE: Patented TeaCrine® is a nature-identical, bioactive form of theacrine, a compound similar in structure to caffeine but without the unwanted side effects, such as increased heart rate and blood
pressure. This powerful, clinically studied ingredient acts on neural pathways, leading to increased energy, focus, alertness, and motivation to train, enhancing your physical and mental performance in the gym.

FERMENTED L-TYROSINE: HOSSTILITY delivers a 1-gram dose of vegan, fermented L-tyrosine. Tyrosine is a precursor to neurotransmitters, which can become depleted during stressful activities like intense training. Tyrosine works to increase these stress-depleted neurotransmitters, supporting enhanced mental performance while you train.

HUPERZINE A 1%: Huperzine A helps to unlock the full potential of Alpha-GPC for enhanced levels of choline in the body. Huperzine A is a potent inhibitor of acetylcholinesterase (AChE), the key brain enzyme responsible for the rapid degradation of acetylcholine. By combining these two powerful nootropics, HOSSTILITY simultaneously supplies the precursor to and protects acetylcholine, lengthening and stabilizing its effects.

INFINERGY: Infinergy™ combines a precise dose of caffeine and malic acid for powerful energy support. The enhanced caffeine matrix in the HOSSTILITY formula utilizes two sources of caffeine to support focus, alertness, and energy, helping you push your workout intensity to the next level. A 135-milligram dose of Infinergy DiCaffeine Malate delivers a total of 100 mg of caffeine per serving. Together with 200 mg caffeine anhydrous, a total of 300 mg of immediate and sustained-release caffeine help promote longer-lasting energy and focus without the crash for more intense workouts.


HOSSTILITY features precise doses of key electrolytes—sodium, potassium, and magnesium—to support hydration and improved muscle function during hard training. This advanced matrix also gives you a clinical 2-gram dose of taurine. Research shows that taurine also helps draw fluid into muscle cells and enhances the body’s ability to utilize
electrolytes. The additional 250 mg of Pink Himalayan Salt combines to make this matrix a powerhouse for supporting hydration, increased muscle performance, and improved blood flow.
