Muscle Nation Immortal High-Stim Pre-Workout – 400mg Caffeine, Clinically Dosed Formula
Muscle Nation Immortal High-Stim Pre-Workout is built for serious lifters who demand more from every session. With 400mg of caffeine per full strength serve and clinical dosages across energy, pump, endurance, and focus, Immortal is engineered to hit hard and keep hitting. If you've outgrown standard pre-workouts, this is the step up.
Key Benefits – Per Full Strength Serve (2 Scoops)
- Hard-hitting, sustained energy — 400mg of caffeine comes from two sources: Caffeine Anhydrous for rapid onset and Di-Caffeine Malate for extended release, supporting 2–3 hours of powerful energy with less crash.
- Serious muscle pumps — 6,000mg of L-Citrulline combined with 1,000mg Agmapure® (Agmatine Sulphate) and L-Norvaline supports strong blood flow and muscle fullness during training.
- Endurance and fatigue resistance — 5,000mg of Beta Alanine and 1,500mg of Taurine work together to buffer lactic acid and help delay fatigue during high-intensity sets.
- Laser focus and mental drive — A 2,255mg nootropic matrix including 1,500mg L-Tyrosine, 500mg Alpha GPC 99%, 250mg L-Phenylalanine, and 5mg Huperzine A supports motivation, mind-muscle connection, and cognitive sharpness.
- Hydration support — 890mg of electrolytes from Pink Himalayan Salt and Potassium Citrate help maintain hydration levels across long or intense sessions.
- Fully transparent label — Every ingredient and dose is listed. No hidden blends, no underdosing.
Built for High-Performance Training
Most pre-workouts fall short on dosages where it matters most. Immortal uses research-backed amounts across all four performance categories — energy, pump, endurance, and focus — rather than splitting budget across a long list of underdosed ingredients. The dual-caffeine matrix means you get the initial drive from Caffeine Anhydrous, followed by sustained output from Di-Caffeine Malate, without the steep drop-off. Piperine (Black Pepper Extract) is included at 5mg to support ingredient absorption. This is a full-spectrum formula designed to elevate every aspect of your session, not just get you amped up.
Directions for Use
Mix 1 scoop (13g / half strength, 200mg caffeine) or 2 scoops (26g / full strength, 400mg caffeine) with water and consume 15–30 minutes before training. New users or those new to high-stimulant pre-workouts should begin with half a serve to assess tolerance before progressing to a full serve. Do not take within 6 hours of bedtime. Do not exceed one full serve per day. Not recommended for evening training sessions.
Each tub contains 40 half strength serves (1 scoop), or 20 full strength serves (2 scoops).

Experienced gym-goers and athletes with a high caffeine tolerance who want a clinically dosed, high-stimulant pre-workout. Ideal for those training heavy compound lifts, early morning sessions, or high-intensity workouts. Not suitable for beginners, caffeine-sensitive individuals, pregnant or breastfeeding women, or anyone under 18 years of age.

FAQs
Why do I feel a tingling sensation after taking Immortal?
The tingling, known as paraesthesia, comes from Beta Alanine (5,000mg per full serve) interacting with nerve receptors under the skin. It typically starts 15–20 minutes after your serve and is temporary and harmless. It fades with regular use as your body adapts.
How much caffeine is in Immortal, and can I take half a serve?
A full serve (2 scoops) contains 400mg of caffeine. A half serve (1 scoop) contains 200mg. If you're new to high-stim pre-workouts, starting with half a serve is strongly recommended to assess your tolerance before moving to a full serve.
Can I take Immortal every day?
You can, but Muscle Nation recommends using it on training days only (typically 4–6 days per week). To avoid building tolerance, cycling 8–12 weeks on followed by a 2–4 week break is advised. Consider your total daily caffeine intake from all sources, including coffee and tea, when using a full serve.
