L-Citrulline in Pre-Workouts
The Bottom Line
Most research points to 6g of pure L-Citrulline per serving as an effective target for pump and endurance benefits, though studies have used doses ranging from 3–8g with varying results. The PwrRanks database shows the Pump category average sits at around 7g — suggesting the industry has settled on 6g+ as the standard.

PwrRanks Take
L-Citrulline is one of the most common pump ingredients in pre-workouts, included in 75% of Pump formulas and 62% of all products in our database. Research on its impact on resistance training has been mixed, though its role in increasing blood flow and nitric oxide production is well-established. Unlike many ingredients that are routinely underdosed, the majority of formulas in our database hit the 6g+ target — making it one of the better-dosed ingredients across the market.
- Well-established pump mechanism
- Most formulas hit the 6g+ target
- Research on resistance training is mixed

What L-Citrulline Actually Does
The pump is hard to put into words — but when you get a good one, it's hard to leave the gym. Arnold famously called the pump "the greatest feeling you can get in a gym," and anyone who's had a sleeve-stretching workout knows exactly what he meant.
L-Citrulline is widely considered one of the most important pre-workout ingredients for dialing in that feeling. It supports nitric oxide production, helping blood vessels relax and increasing blood flow to working muscles. More blood flow means fuller muscles, better pumps, and that thick, solid, tight feeling that keeps you coming back day after day.
