INTENSITY: The Science Behind the Formula

Formula Design Philosophy

When I first set out to create INTENSITY, one idea sat at the core of everything: this had to be something you could rely on every single day.

Too many products on the market hit hard once — then leave you feeling wrecked, anxious, or flat, killing your appetite and your recovery. That was never the goal. INTENSITY was designed to support performance without punishing the body for using it.

The focus was on clean, sustainable energy and full-day functionality. Something that fuels you from the moment you wake up to when you shut it down at night — whether you train early, late, or anywhere in between. No crashes. No sick feeling. No appetite suppression that throws everything else off.

INTENSITY was also built to grow with you. One scoop provides a smooth, controlled experience that’s ideal for beginners or anyone sensitive to stimulants. Two scoops unlock the full performance potential for experienced lifters who demand more from their training — without sacrificing balance or control.

INTENSITY isn’t about overstimulation. It’s about balance — supporting strength, focus, and output while respecting recovery, digestion, and long-term health. A formula built not just to perform, but to last.

L-Citrulline – 6,000 mg

L-Citrulline is a powerhouse amino acid known for enhancing nitric oxide (NO) production, which promotes vasodilation — the widening of blood vessels.
This process increases blood flow, oxygen delivery, and nutrient transport to working muscles, resulting in bigger pumps, greater endurance, and reduced fatigue.
At 6,000 mg, INTENSITY delivers the clinical dose used in performance studies, ensuring maximum results without unnecessary fillers.

Malic Acid – 2,000 mg

Malic Acid works synergistically with Citrulline to create Citrulline Malate, a compound that boosts the Krebs cycle — your body’s primary energy pathway.
This helps enhance ATP production, delay muscle fatigue, and improve overall training capacity, allowing you to push harder for longer.

Betaine Anhydrous – 2,500 mg

Betaine (Trimethylglycine) supports strength, power output, and muscle hydration by acting as an osmolyte — maintaining fluid balance in muscle cells.
It’s clinically shown to support improved endurance, enhanced muscle growth, and better recovery, making it a staple for athletes who train with intensity.

Taurine – 1,500 mg

Taurine plays a vital role in hydration, electrolyte balance, and muscle function.
It supports cellular water retention (volumization), promotes mental focus, and helps protect against oxidative stress during intense workouts.
When combined with caffeine, Taurine helps smooth out energy delivery — sustaining performance without overstimulation.

L-Tyrosine – 2,000 mg

L-Tyrosine is a precursor to key neurotransmitters like dopamine, adrenaline, and noradrenaline, which are essential for mental clarity and focus under stress.
At 2,000 mg, this high dose supports enhanced concentration, motivation, and resilience, especially in long or high-intensity training sessions.

Theobromine (from Cocoa) – 200 mg

Theobromine is a natural stimulant derived from cocoa that provides smooth, sustained energy and mild vasodilation without the crash.
It enhances cognitive function, mood, and circulation, complementing caffeine for a cleaner, more focused stimulation effect.

Caffeine Anhydrous – 300 mg

The gold standard of energy.
Caffeine Anhydrous increases alertness, endurance, and reaction time while reducing the perception of fatigue.
At 300 mg, INTENSITY delivers a powerful yet controlled energy boost — perfect for athletes seeking peak performance without jitteriness.
Combined with Theobromine and Tyrosine, it creates a balanced, synergistic stimulant matrix.

Citicoline – 250 mg

Citicoline (CDP-Choline) is one of the most effective forms of choline for enhancing brain energy and cognitive function. It plays a key role in the production of acetylcholine, the neurotransmitter essential for focus, learning, and the mind-muscle connection. Sodium citicoline has been studied for its ability to support mental clarity, improve reaction speed, and boost overall cognitive performance — making it a powerful nootropic component in INTENSITY.

Magnesium (as Bisglycinate) – 50 mg

Magnesium is essential for muscle contraction, relaxation, and energy metabolism.
The Bisglycinate form offers superior absorption and gut comfort, helping to reduce muscle cramps and support recovery post-workout.

Potassium (as Potassium Chloride) – 200 mg

Potassium is a key electrolyte that helps maintain muscle function, hydration, and nerve signaling.
By replenishing potassium lost through sweat, it helps sustain performance consistency throughout your training.

Sodium – 200 mg

Sodium plays a vital role in maintaining hydration, supporting muscle contractions, and facilitating nutrient transport across cell membranes. By promoting optimal electrolyte balance, sodium helps reduce the risk of fatigue and muscle cramps during intense physical activity — making it an essential component for peak performance and endurance.

Vitamin B6 (as P5P) – 10 mg

Vitamin B6 in its active form, Pyridoxal-5-Phosphate (P5P), supports energy metabolism, neurotransmitter synthesis, and amino acid utilization.
It aids in converting nutrients into usable energy — ensuring you get the most from every scoop.

Vitamin B12 (as Methyl-B12) – 500 mcg

Methylcobalamin is the most bioavailable form of Vitamin B12, crucial for energy production and red blood cell formation.
It helps combat fatigue and supports mental alertness, keeping you locked in throughout your workout.

Niacin (Vitamin B3) – 16 mg

Niacin supports energy metabolism and blood flow, enhancing oxygen delivery to muscles.
It also contributes to the “niacin flush” — a temporary warming sensation signaling increased capillary dilation and improved nutrient delivery.

The Synergy of INTENSITY

Each ingredient in INTENSITY isn’t just dosed effectively — it’s strategically paired for maximum synergy.

Citrulline + Malic Acid = unmatched endurance and pumps

Caffeine + Theobromine + Tyrosine + Citicoline = clean energy and laser focus

Taurine + Electrolytes + B-Vitamins = hydration and recovery support

INTENSITY delivers a complete pre-workout experience — not just energy, but performance that lasts from your first rep to your final set.

Why We Chose Not to Include Beta-Alanine

At Solas Nutrition, every ingredient in our INTENSITY formula serves a specific, evidence-based purpose — no filler, no fluff.
That’s why we made the conscious decision not to include Beta-Alanine, despite its popularity in many pre-workouts.

While Beta-Alanine can help buffer lactic acid and delay fatigue during high-intensity exercise, it also causes a common side effect known as paresthesia — the tingling or itching sensation many users experience shortly after consumption.

For some, this feeling is harmless. But for others, it’s distracting, uncomfortable, and can even reduce focus — the opposite of what a high-performance pre-workout should do.

At Solas Nutrition, our focus is on clarity, control, and consistency.
We believe true performance comes from clean, targeted energy, mental precision, and clinical dosing that enhances every aspect of your training — without unnecessary discomfort or gimmicks.

By excluding Beta-Alanine, INTENSITY delivers a smooth, focused energy profile that keeps you locked in from your first rep to your last — so every scoop feels as good as it performs.
