Evidence summary
Research confidence: high
base form; 6 g citrulline malate 2:1 ≈ 4 g L-citrulline. The meta-analysis's most common protocol (8 g CM, 2:1 mass ratio) yields ≈5.3 g L-citrulline and produced a small but significant increase in reps-to-failure (~3 reps, +6.4%); dose-response was flat above ~8 g CM.
