The evidence in words
How much to take
6–8 g of L-citrulline (or 8 g citrulline malate) about an hour before training. Consistency isn't required day-to-day; it's an acute ergogenic.
Timing & separation
There are no strict timing conflicts on record for L-Citrulline; consistency matters more than the exact hour for most goals.
Why the dose is what it is
By raising plasma arginine and nitric-oxide availability, citrulline promotes vasodilation and blood flow to working muscle, and it helps clear ammonia via the urea cycle, which may delay fatigue.
Bottom line
One of the few pre-workout ingredients with real, if modest, support. 6–8 g an hour before lifting for reps and pump; also a mild blood-pressure helper.
How it is used
