? L-Arginine vs Citrulline
When it comes to maximizing your muscle pumps and blood flow during workouts, two major players step into the ring: L-arginine and citrulline. Both are amino acids popular in the pre-workout world, but which one truly boosts your training? At preworkout.pro, we break down the science, their roles in recovery and performance, and how Bucked Up leverages these ingredients to fuel your sessions.
What Are L-Arginine & Citrulline? Why Do They Matter?
L-arginine is an amino acid best known for directly raising nitric oxide (NO) levels, relaxing blood vessels and promoting better circulation. Citrulline, on the other hand, gets converted to arginine after ingestion—often resulting in more sustained NO boost than L-arginine itself. Better NO production means improved nutrient delivery, monster pumps, and crazy vascularity during intense training.
- Increased muscle endurance
- Massive pumps & vascularity
- Enhanced recovery and nutrient uptake
Choosing between the two depends on your goals—but knowing how they work together can take your routine to new heights.
How L-Arginine & Citrulline Fit Bucked Up Formulas
Many Bucked Up pre-workouts strategically blend L-citrulline (often in the pure form, not citrulline malate) for longer-lasting pumps. L-arginine is less common because citrulline has a higher bioavailability and delivers a bigger boost in the gym. For example, PUMP-OCALYPSE dials up the nitric oxide with a hefty hit of citrulline for sleeve-busting pumps. Classic choices like Bucked Up Pre-Workout also feature clinically-studied citrulline dosages, ensuring you get the most effective results possible. Looking for variety?

❓ FAQ
- Can I stack L-arginine and citrulline?
Yes! Combining both can supercharge nitric oxide, but most prefer citrulline for efficiency. - Does citrulline work better than L-arginine?
For most, yes—citrulline is absorbed better and gives a more powerful, lasting pump. - How soon before a workout should I take them?
30 minutes pre-workout is ideal, as part of your Bucked Up routine.
