Muscle Rulz Glutamine 5000mg restores depleted levels of this amino acid and aids protein synthesis for improved overall performance. Our specially formulated powder is highly concentrated and contains more essential Glutamine than food sources alone. It's incredibly versatile and mixes easily into whey protein and mass gainer shakes for easy and convenient supplementation throughout the day and while on the go. And as with all Muscle Rulz products, pure and high-quality ingredients are at the heart of our passion.
