Athenix® ULTRA NITRO-X is a high-performance pre-workout engineered for explosive power, muscular endurance, intense focus and sustained training energy — without relying on excessive stimulants or unnecessary sugar.
Built around 5,000 mg L-Citrulline, 2,500 mg Beta-Alanine, 1,500 mg Creatine HCL and 175 mg Caffeine, Nitro-X combines serious performance doses with premium branded actives including OxyStorm® and AstraGin® to support the entire training session — from first rep to last.

- 2,500 MG BETA-ALANINE: Supports muscular endurance and sustained high-intensity performance as fatigue builds.
- 1,500 MG CREATINE HCL: Supports explosive strength, power and repeated muscular performance.
- 175 MG CAFFEINE: Controlled stimulation for energy, alertness and training drive without turning Nitro-X into a caffeine bomb.

- CHOLINE + L-THEANINE: Supports mental clarity, concentration and a smoother, more controlled energy profile.
- ASTRAGIN®: Premium botanical complex included to support nutrient absorption and utilisation.
- ZERO SUGAR. ZERO FAT. NO ARTIFICIAL COLOURS: Performance first. Nothing unnecessary.
THE ATHENIX® DIFFERENCE
Most pre-workouts are built around one question:
How much caffeine can we put in it?
NITRO-X was built around a different question: how do we improve the entire workout?
That means combining pump, nitric oxide support, muscular endurance, explosive power, controlled stimulation, cognitive focus and nutrient-delivery support in one precision-engineered formula.
OxyStorm®. AstraGin®. L-Citrulline. Beta-Alanine. Creatine HCL. Choline. L-Theanine.
Mix 1 slightly heaped scoop (13 g) with 350 ml of water and shake or stir until fully dissolved.
Take 15–30 minutes before training.
Because Nitro-X contains caffeine, avoid taking it within 5 hours of sleep.
