5% Nutrition Core L-Citrulline 3000 with Glycerol Nitric Oxide Booster & Muscle Pump Pre-Workout Supplement - 60 Servings (Unflavored)

There's nothing greater than looking in the mirror after a brutal workout and seeing your muscles swollen to their limits. Taking proven ingredients before your workout is the best way to achieve THE PUMP.

L-Citrulline is the #1 go-to ingredient for muscle swelling pumps in the gym. Your body readily converts L-Citrulline into L-Arginine, which boosts nitric oxide levels. Increased production of nitric oxide promotes vascular dilation, improving oxygen and blood circulation throughout the body. So, why not just take L-Arginine? It's so poorly absorbed by the body that it makes far more sense to consume its precursor, L-Citrulline.
Here's an example. If you take the industry average 1500mg blended dose of Citrulline/Arginine, you're potentially only getting 750 mg of the effective amino acid, and that's IF the manufacturer formulated a 1:1 ratio. 5% Nutrition focuses on the important stuff, and blows the other guys out of the water.

GlycerSize is an advanced form of Glycerol that delivers a more effective dose per gram than any other glycerol product on the market. It supports improved hydration and nutrient absorption due to its ability to enhance cells' ability to absorb water. Think of your muscles as sponges... GlyerSize makes them ultra-absorbent, encouraging them to soak up water and extra nutrients. This in turn improves performance, endurance, vascularity, and fullness. Combined with L-Citrulline it provides a powerful one-two punch that delivers massive pumps.

The new 5% Core line from 5% Nutrition delivers the ability to stack, combine, and customize your workout supps in a way that works for YOU.
