There’s also a research-inspired dose of L-Citrulline for better pumps plus a grape and apple extract blend.
In the past, arginine was a staple in most pre-workout products due to its ability to increase Nitric Oxide (NO). Then, a few years ago, research emerged that showed L-Citrulline was extremely effective at increasing blood arginine levels. Citrulline is a precursor of arginine and it provides a readily available material for arginine production, which in turn can be used for the production of NO. In fact, compared to a larger dose of arginine, L-citrulline has been scientifically shown to reach superior peak plasma arginine levels, making it a far better choice for NO production in your pre-workout! This is due to arginine itself, when consumed as a supplement, excessively breaking down in the body. Citrulline, on the other hand, is less susceptible to these destructive metabolic pathways, making it far more effective and efficient.
