C4 Ultimate Icy Blue Razz is a high-stimulant, comprehensive pre-workout formulated for intense energy, strong pumps, improved endurance, and sharp mental focus during workouts.

Analysis

C4 Ultimate Icy Blue Razz delivers a high-impact pre-workout experience, featuring an identical ingredient profile to other C4 Ultimate flavors. It contains 300mg of Caffeine Anhydrous for intense energy, coupled with 62mg of Theacrine for a sustained and smooth energy curve. The formula is designed to maximize physical performance with 3g of CarnoSyn Beta-Alanine to buffer lactic acid and improve endurance, and 6g of C4 Super Citrulline Pump Matrix for significant nitric oxide production and muscle pumps. Cognitive performance is addressed by 200mg AlphaSize (Alpha-GPC), 50mcg Huperzine A, and 400mg N-Acetyl-L-Tyrosine, promoting sharp focus and mental drive. Additionally, it includes 1g Taurine for hydration and endurance, and 2g total of Creatine Nitrate and Creatine Hydrochloride for strength benefits. The presence of 1mg Rauwolfia vomitoria root extract adds a strong thermogenic and stimulant component, which while potent, may lead to increased side effects in some users.

Pros
  • Offers a very strong energy surge and sustained focus due to the high stimulant content, including caffeine and Theacrine.
  • Provides an effective dose of Citrulline for significant muscle pumps and enhanced nutrient delivery.
  • Contains Beta-Alanine at a beneficial dose for improving muscular endurance and reducing fatigue.
  • Includes a comprehensive blend of nootropics to enhance mental clarity and concentration during workouts.
  • Features two forms of creatine, supporting strength and power gains.
Cons
  • The combination of 300mg caffeine and Rauwolfia vomitoria can be overly potent for individuals sensitive to stimulants, potentially causing anxiety or jitters.
  • The 2g total creatine dosage is below the clinically recommended daily dose for optimal muscle saturation, requiring additional supplementation for maximum benefit.
  • High price point per serving may deter budget-conscious consumers.
Warnings
  • Excessive stimulant content (Caffeine, Theacrine, Rauwolfia vomitoria) can lead to side effects such as increased heart rate, blood pressure, anxiety, and sleep disturbances.
  • Rauwolfia vomitoria root extract is a powerful stimulant that may cause uncomfortable side effects like cold sweats and an agitated feeling in sensitive individuals.
  • Beta-Alanine can cause a harmless tingling sensation (paresthesia) which some users may find unpleasant.

Report overview

Categories

The 300mg Caffeine Anhydrous dose, combined with Theacrine, delivers an extremely potent and extended energy kick, making it highly effective for users seeking maximum stimulation.
At 50mcg, Huperzine A is sufficiently dosed to aid in prolonging acetylcholine's effects, thereby improving focus, learning, and mental endurance.
The 200mg of AlphaSize (Alpha-GPC) is a good starting dose for cognitive benefits and power output, though some evidence supports higher dosages for more pronounced effects.

Goals

The potent combination of 300mg Caffeine Anhydrous and 62mg Theacrine provides an intense and sustained energy boost, ideal for pushing through demanding workouts without a sudden crash.
AlphaSize, Huperzine A, and N-Acetyl-L-Tyrosine work synergistically with the caffeine to promote sharp mental focus, improved concentration, and a strong mind-muscle connection during exercise.
The enhanced energy and razor-sharp focus offered by this formula directly translate into increased productivity and drive, enabling more intense and efficient workout sessions.
