Buddy, if you're low on carbs because you're dieting, don't expect miracles from any pump product. Fuel matters.
I've tried a bunch of fancy pre-workouts over the years. Most of the time I end up coming back to plain citrulline and making sure I eat enough before training.
Appreciate all the input, guys. Sounds like the winning combo is keeping the basics dialed in first, then adding things like glycerol or nitrates if needed. Definitely giving a few of these ideas a shot next week.
