Nitrox Pump Caffeine+ is a pre-workout supplement for athletes who can generate brutal intensity in a short amount of time and need to ensure their bodies can withstand that intensity. NITROX PUMP CAFFEINE+ is based on the synergy of citrulline, A-AKG, beta-alanine, and creatine HCl, which create the conditions for uncompromisingly intense sets.

The Neurofocus complex (tyrosine, theanine, CDP-choline), supplemented with caffeine and synephrine, supports focus and controlled intensity management—without overstimulation. Nitrox Pump Caffeine+ is designed for those who don’t need motivation, but a tool that lets them fire on command and hit the mark precisely. For athletes who train hard, fast, and to the fullest—and want a product as reliable as they are.

Nitrox Pump Caffeine+ — a product for short, intense workouts

Nitrox Pump Caffeine+ is a pre-workout for athletes who train short, hard, and want to perform at their absolute best within a limited time frame.

It doesn’t promise a “quick fix”—it’s based on the physiology of intensity: blood flow, muscle contractions, rapid onset, and the ability to perform at peak without losing precision.

The formula is based on high doses of citrulline, beta-alanine, and A-AKG, which are included to support blood flow and the mechanics of intense sets. The taurine in the formula acts as an osmolyt commonly used to stabilize the environment inside muscle cells.

The Neurofocus complex (tyrosine, theanine, CDP-choline) is designed to meet the needs of rapid onset and intensity control—without overstimulation. Caffeine and synephrine effectively complement this onset. Nitrox Pump Caffeine+ is for those with extreme dedication and discipline. For them, training means a quick start and an uncompromising impact.

Performance & Pump — a synergy that sustains intensity

In a short, intense workout, it’s not just one ingredient that makes the difference. What matters is the environment you can create within your muscles. Nitrox Pump Caffeine+ is built on a combination used in sports nutrition precisely when you need to “explode” and maintain intensity throughout an entire set.

Citrulline malate (6.5 g)

Citrulline is one of the most widely used substances for promoting blood flow and localized muscle work at higher intensities. The dose in Nitrox is designed for heavy training loads, not just a token pump.

A-AKG (3 g)

A-AKG is a combination of arginine and alpha-ketoglutarate, used specifically to target the pump, optimal blood flow, and localized muscle exertion. It works well on its own—but it has the strongest effect when combined with citrulline, since each works through a different mechanism.

Citrulline + A-AKG Synergy

Both amino acid forms are used in sports nutrition to support the conditions required for intense training: improved blood flow, more stable muscle performance, and the ability to maintain high-quality contractions even at a demanding pace. Together, they create an environment that athletes describe as a stronger pump and better power during sets—without stimulants.

Beta-alanine (3 g)

Beta-alanine is a common and long-established solution for high-intensity workouts. The dosage is designed to support short, intense bursts of effort—not extreme paresthesia.

Creatine HCl (2 g)

Creatine is one of the most thoroughly researched substances in sports nutrition. The hydrochloride form offers good solubility and precise dosing—ideal for a pre-workout.

Neurofocus & Energy — Fast-Acting, Clear-Headed

Intense training isn’t just about muscles. It’s about how quickly you can shift into performance mode and how precisely you can maintain your technique when pushing yourself to the limit. Nitrox Pump Caffeine+ is based on a combination of ingredients used in sports nutrition specifically for this type of performance—a fast onset, clear focus, and controlled intensity.

L-tyrosine

An amino acid commonly included in products designed to help you maintain a clear and focused mind during physical exertion.

L-theanine

It’s known for being used in situations where you need a calm mind without drowsiness. Combined with tyrosine, it creates a state where you’re both relaxed and fully focused.

CDP-choline

A compound used in nootropic blends where coordination and precision of movement are important—even at a fast pace.

Caffeine + Synephrine (10 mg)

A carefully selected combination for a faster onset and a boost of drive, not overstimulation. Athletes use it when they need to “get into gear immediately” while maintaining full control.

The result?

An instant start. Clear focus. Controlled performance intensity.

Who is Nitrox Pump Caffeine+ for?

Nitrox isn’t a one-size-fits-all pre-workout. And it doesn’t want to be. It’s for athletes who know how to be tough in the best sense of the word. For those who can generate intensity that hurts in a short amount of time—and see it as part of their identity. It’s for people who possess more discipline than most can imagine. And who want a scientifically formulated product that gives them a fast onset and the ability to instantly shift into performance mode, where mind and body meet in the same moment.

Nitrox is based on a combination of substances that do one thing: they create the conditions for hard, precise, and controlled work. Nothing more. Nothing extra. Just an environment that delivers: blood flow where you need it, muscle contraction that doesn’t falter mid-set, and focus that stays sharp even when you’re pushing the limits. Nitrox was created for athletes who don’t seek motivation—they live it. All they need is the ability to fire quickly and hit the mark precisely. And they know that their performance deserves a tool that’s just as reliable as they are.

Nitrox Pump Caffeine Free Clean 23.5 g

Product Concept

During intense strength training, athletes place increased demands on their bodies in terms of blood flow to muscle tissue, cellular hydration, and neuromuscular coordination.

One of the key factors in performance is the production of nitric oxide (NO), which helps regulate vascular tone and blood flow in muscle tissue. Adequate blood flow to the muscles influences the transport of oxygen, nutrients, and metabolic byproducts produced during muscle work.

In addition to blood flow, the volume of muscle cells, the availability of substrates for muscle contraction, and central nervous system regulation of performance also play a role.

Pre-workout supplements of this type use ingredients designed to:

• supporting nitric oxide synthesis
• cellular hydration and osmotic balance
• the availability of energy substrates for rapid ATP resynthesis
• central nervous system regulation of performance through effects on neurotransmitters (dopamine, norepinephrine, acetylcholine)
• mental focus and cognitive performance during training

This product combines all these approaches in a caffeine-free pre-workout blend. Plus, the formula features all-natural flavoring.

Ingredients and Functional Profileof the product:

L-citrulline malate (2:1) — 7,000 mg

L-citrulline is an amino acid that increases the availability of L-arginine in the body and can thereby indirectly support nitric oxide (NO) synthesis via NO synthase.

In the scientific literature, citrulline has been studied in relation to:

• increased plasma availability of arginine and the substrate for NO synthase 1 5
• hemodynamic responses to exercise (blood flow through active muscle tissue) 2 4 5
• performance during repeated sets and subjective perception of exertion 1 5
• muscle soreness and markers of muscle damage after training 1 2 3

Beta-alanine — 3,000 mg

Beta-alanine is the rate-limiting precursor of the dipeptide carnosine in muscle tissue. Carnosine acts as an intracellular buffer for hydrogen ions (H+) generated during intense glycolytic exercise.

In the scientific literature, beta-alanine is studied primarily in relation to:

• increased muscle concentrations of carnosine 6 7
• buffering metabolic acidosis during intense exercise 6 9
• performance during high-intensity intervals and repeated sets 7 9

A-AKG (L-arginine alpha-ketoglutarate) — 3000 mg
