Description

Unleash your full athletic potential and dominate every gym session with Optimum Nutrition Gold Standard Pre-Workout. Crafted for athletes, bodybuilders, and active fitness enthusiasts, this premium energy formula combines trusted, high-grade ingredients to deliver clean energy, razor-sharp focus, and enhanced muscle endurance without the harsh post-workout crash.

Key Benefits & Features

  • Explosive Energy & Focus: Formulated with 175mg of natural caffeine derived from tea and coffee beans to heighten mental drive and intensity.

  • Enhanced Muscle Endurance: Packed with 1.5g of CarnoSyn® Beta-Alanine to help buffer lactic acid accumulation and delay muscle fatigue.

  • Pump & Blood Flow Support: Includes 750mg of Micronized L-Citrulline to encourage nitric oxide production and enhanced vascularity.

  • Performance & Power Amplification: Fortified with Creapure® Creatine Monohydrate to support ATP regeneration and explosive physical output.

  • Banned Substance Tested: Rigorously screen-tested under the Informed-Choice program for absolute peace of mind and quality assurance.

How It Works

Optimum Nutrition Gold Standard Pre-Workout relies on a synergy of performance-proven active ingredients. Natural caffeine triggers central nervous system alertness, providing sustained energy without jittery side effects. CarnoSyn® Beta-Alanine increases muscle carnosine levels, allowing your muscle fibers to fight off acidity during intense, high-repetition sets.

Simultaneously, Micronized L-Citrulline drives nutrient-rich blood flow straight to working muscles, while Creapure® Creatine Monohydrate fuels cellular energy reserves (ATP). This combination ensures you can push harder, lift heavier, and maintain peak athletic output from your first rep to your last.

Recommended Use

The best pre-work out I've ever had. I've been using it for over a year now. I love the watermelon and green apple flavor.

I haven't tried many pre-workouts cause I fell in love with ON from the start. I've tried the green apple, blueberry lemonade and the pineapple. So far pineapple is the best!

8/10 Green Apple

First time trying a pre-workout so have nothing to compare to but definitly makes me feel more focused on days where I'm fatigued and tired and gives me a noticeable boost. Keen to try other flavours too.

Great stuff. We got a free sample of it when we signed up to our gym and went online that night to buy it. Great taste, helpful energy boost and great value for money when you consider how many servings you can make from it. Only note is I recommend halving the servings because it is quite a strong taste and if you aren't used to it it's very intense.
