Buying Guide: What to Look for in a Pre Workout
Citrulline for Nitric Oxide and Pumps
L-Citrulline is a non-essential amino acid that your body converts into arginine, boosting nitric oxide levels. This vasodilation improves blood flow to working muscles, delivering oxygen and nutrients while clearing waste products. The result: enhanced muscle pumps, better endurance, and reduced fatigue. RAW Essential Performance Non-Stim Pre-Workout contains L-Citrulline, making it a solid choice for those who want these performance benefits without relying on caffeine.
Stimulant-Free vs Stimulant Pre Workouts
The absence of caffeine or other stimulants is a key differentiator. If you train in the evening, are sensitive to caffeine, or want to avoid jitters and crashes, a non-stim pre workout like RAW Essential Performance is ideal. In contrast, many pre workouts with citrulline also include caffeine. Deciding between the two depends on your training schedule and tolerance. For more on stimulant comparisons, see our review of pre workout vs coffee.
Complete Ingredient Profile
Beyond citrulline, look at the supporting ingredients. RAW Essential Performance includes 5 grams of Creatine Monohydrate per serving for strength and recovery, Beta Alanine to buffer lactic acid, Betaine Anhydrous for cellular hydration, and L-Tyrosine for focus. These work synergistically with citrulline. If you are comparing pre workouts, note that products lacking citrulline often rely solely on caffeine or beta alanine.

Flavor and Mixability
A pre workout is only useful if you actually want to drink it. RAW Essential Performance comes in two flavors: Blue Rathberry and Champion Mentality. Both are designed to be palatable without artificial additives. The powder mixes easily with water and leaves no grittiness. If taste is a priority, these options deliver a juicy, clean experience.
Final Thoughts
Choosing between a pre workout with citrulline and one without comes down to your goals. If you value nitric oxide boosting, muscle pumps, and improved endurance without stimulants, the RAW Essential Performance Non-Stim Pre-Workout in Blue Rathberry is a standout option. For those who prefer a different flavor profile, the RAW Essential Performance Non-Stim Pre-Workout in Champion Mentality offers the same powerful formula. Both are excellent choices for athletes and fitness enthusiasts who want a citrulline-packed, caffeine-free pre workout to support their training.
Frequently Asked Questions
What does L-Citrulline do in a pre workout?
L-Citrulline boosts nitric oxide production, which dilates blood vessels and improves blood flow to muscles. This leads to better pumps, enhanced endurance, and quicker recovery. It is a key ingredient in many pre workouts designed for performance, especially those without stimulants.
Is a pre workout with citrulline better than one without?
For most lifters and athletes, yes, citrulline offers distinct advantages in terms of blood flow and endurance. However, if you are focused solely on mental energy or prefer a minimal ingredient list, you might choose a pre workout without it. The best choice depends on your specific training needs in 2026.
Can you take citrulline pre workout without caffeine?
Absolutely. Many non-stim pre workouts like RAW Essential Performance include L-Citrulline without any caffeine. This is perfect for evening workouts, caffeine-sensitive individuals, or those who want to avoid the crash. For a broader comparison of stimulant-free and caffeinated pre workouts, see our guide on pre workout vs energy drink.
How much citrulline should be in a pre workout for results?
Clinical studies typically use doses of 6 to 8 grams of L-Citrulline per serving to maximize nitric oxide benefits. Many pre workouts, including RAW Essential Performance, provide a lower but still effective amount, often around 6 grams per scoop. Check the label to ensure you are getting a meaningful dose for your goals.
