• Bucked Up offers several pre-workout formulas with transparent dosing and Citrulline-based support for energy, focus, pump, and endurance at different stimulant levels.
• Lifters who want a transparent C4 alternative with Citrulline Malate can use Bucked Up Pre-Workout as a starting point.

Why Many Lifters Move Beyond C4 Pre-Workout

The pre-workout category has shifted from simple caffeine formulas to more complete performance products. Many athletes now look for support with pump, endurance, and focus, not only a buzz of energy.

C4 can provide a basic energy lift, yet some users want clearer labels and higher doses of specific ingredients such as Citrulline Malate. They often look for:

• Stronger or more sustained muscle pumps
• Better muscular endurance and work capacity
• Less mid-workout crash from stimulants
• Full, non-proprietary ingredient panels

Matching a pre-workout to your needs means aligning stimulant level, ingredient profile, and personal tolerance. Newer lifters often do best with moderate caffeine and clean formulas, while advanced athletes may choose higher-stimulant options that still prioritize performance ingredients, not only stimulants.

How Citrulline Malate Supports Pump and Endurance

Citrulline Malate combines the amino acid L-Citrulline with malic acid. L-Citrulline converts to arginine in the body, and this pathway raises arginine levels more effectively than taking arginine alone. Higher arginine can increase nitric oxide, which promotes vasodilation, blood flow, and pump.

Malic acid contributes to the Krebs cycle, which may support energy production during exercise. When combined, these effects can help with both pump and endurance. Doses around 6–8 grams of Citrulline Malate taken 30–60 minutes before training have been associated with reduced fatigue, higher work capacity, and improved performance in both aerobic and anaerobic efforts. Increased oxygen delivery to working muscles further contributes to performance support.

An acute 8 gram dose of Citrulline Malate about one hour before lifting has been shown to improve dynamic muscular endurance and strength in trained lifters. Eight grams before weight training has also been linked with more reps per set, delayed fatigue, and reduced post-workout soreness. Even lower chronic doses may help, as 2.4 grams per day for 7 days shortened a 4 km cycling time trial by about 1.5%.

Key Features to Prioritize in a C4 Alternative

A well-designed C4 alternative does more than increase alertness. It should provide clinically aligned doses of performance ingredients with full transparency.

• Citrulline dosing: Effective pre-workout ranges include roughly 6–8 grams of pure L-Citrulline or about 8 grams of a 2:1 Citrulline Malate.
• Transparent labels: Each ingredient should list its exact amount instead of appearing inside a proprietary blend.
• Synergistic ingredients: Beta-Alanine for buffering fatigue, nootropics such as AlphaSize Alpha GPC for focus, and measured caffeine for energy and alertness.
• Advanced pump and recovery support: Additions like Nitrosigine for blood flow, Astragin for absorption, and Senactiv for performance and recovery support.
• Quality standards: Manufacturing in reputable facilities and a consistent track record of clear, accurate labeling.

Frequently Asked Questions

What is the optimal dosage of Citrulline Malate for exercise performance?

Most performance-focused protocols use 6–8 grams of Citrulline Malate about 30–60 minutes before training. This range supports nitric oxide production, blood flow, and delayed fatigue for many lifters.

How does L-Citrulline differ from Citrulline Malate, and which is better for pre-workouts?

L-Citrulline is a standalone amino acid. Citrulline Malate pairs L-Citrulline with malic acid, usually in a 2:1 ratio. L-Citrulline efficiently raises arginine levels and supports nitric oxide production, while malic acid may help energy production through the Krebs cycle. Many pre-workouts favor Citrulline Malate for its combined pump and endurance support.

Can Citrulline Malate help reduce muscle soreness?

Some research links Citrulline Malate with lower perceived soreness after hard training, but findings are mixed across different protocols. The more consistent benefits involve increased work capacity, improved pump, and better endurance during the session itself.

Are there any side effects of Citrulline Malate supplementation?

Citrulline Malate is generally well tolerated at common performance doses. Most healthy users can take 6–8 grams pre-workout without major issues, although starting at the lower end of the range is a practical way to gauge personal tolerance.

Should I cycle off pre-workouts containing Citrulline Malate?

Citrulline Malate itself does not usually require cycling, because it does not act like a stimulant. Cycling often relates to caffeine and other stimulants. Many lifters rotate to non-stimulant pre-workouts that still contain Citrulline Malate during breaks from higher caffeine use.

Using Citrulline Malate Pre-Workouts to Support Training in 2026

Modern lifters now look for pre-workouts that combine clear labels, effective doses, and performance ingredients such as Citrulline Malate. Products like C4 introduced many users to pre-workouts, yet more advanced formulas give greater control over pump, endurance, and focus.

Bucked Up offers several options that center on Citrulline-based support while varying stimulant level and nootropic content. This structure lets users start with moderate formulas, then move to higher-stimulant or non-stimulant products as training demands and caffeine tolerance change.

Identify your main goals, choose a stimulant level that matches your schedule and sensitivity, and select a formula with transparent dosing of Citrulline, Beta-Alanine, and focus ingredients. For a straightforward starting point, consider Bucked Up Pre-Workout and adjust from there as your training progresses.
