Not every session needs a wall of caffeine. Late workouts, caffeine sensitivity, or just wanting to sleep tonight — there are plenty of reasons to go stim-free. The good news: the pump doesn't come from stimulants. It comes from blood flow.
What drives a pump
Ingredients like L-Citrulline support nitric oxide production, which supports blood flow to working muscles — that's the full, tight feeling you chase in a high-rep set.*
Three ways to do it with Synful
1. Keep it simple — L-Citrulline. One 5 g scoop of pure L-Citrulline, nothing else. Add it to any pre-workout or take it on its own.
