Start with the form on the label
A pre-workout with L-citrulline should tell you which form it contains and how much is in the serving. Pure L-citrulline and citrulline malate are different label measurements. The malate portion contributes to the weight of citrulline malate, so comparing the biggest number on two tubs can be misleading.
Citrulline participates in the body’s arginine–nitric oxide pathway, which is why it appears in products marketed for blood flow and pumps. That rationale does not establish a guaranteed improvement in repetitions, muscle growth or recovery from a particular pre-workout.
What do exercise trials show?
In a randomized crossover trial in 41 men, 8 g citrulline malate improved performance in a repeated bench-press protocol and reduced reported soreness. Some participants reported stomach discomfort.
A different randomized crossover trial in 27 men tested 8 g citrulline malate during repeated leg extensions and found no benefit for the measured performance or blood-flow outcomes. Differences in exercise, participants and timing matter.
These studies support a cautious conclusion: some protocols have produced benefits, but an 8 g serving does not consistently improve every type of training. Neither study tested the Bucked Up blends below, and neither proves that a temporary pump causes long-term hypertrophy.
How to compare citrulline amounts
- Pure L-citrulline: The listed amount refers to that ingredient.
- Citrulline malate: Look for a declared ratio. If 6 g is genuinely a 2:1 mixture by weight, the arithmetic gives about 4 g citrulline and 2 g malate.
- No ratio stated: Do not assume that all the listed weight is citrulline or invent an exact equivalent.
- One versus two scoops: Keep the serving basis consistent when comparing ingredients and cost.
The 2:1 calculation is label arithmetic, not an independent assay or proof that two different products perform identically.
Where the linked Bucked Up products fit
Original Bucked Up lists 6 g citrulline malate 2:1 and 200 mg caffeine. The blend amount should not be relabeled as 6 g pure L-citrulline.
WOKE AF also lists 6 g citrulline malate 2:1, with 333 mg caffeine and other stimulants. More caffeine does not change the citrulline content into a stronger demonstrated pump effect.
If you want to avoid caffeine, check a separate caffeine-free formula on its own merits. Do not assume every product from the same brand has the same citrulline source, serving or stimulant ingredients.
Using the information sensibly
Follow the actual product directions. Do not take additional scoops of a caffeinated blend merely to reach a citrulline amount used in a study; that also increases caffeine and every other ingredient. Combining pump products can create the same problem with overlapping ingredients.
Ask a clinician or pharmacist before use if you take medication affecting blood pressure or have a relevant medical condition. Keep expectations tied to your training program, and evaluate tolerance rather than chasing visible vascularity.

Bottom line: Compare the form, ratio and serving before the headline gram number. Citrulline is an optional training ingredient with mixed exercise results, not an essential requirement for a productive workout.
