Because it’s unflavored and instantized for easy mixing, you can add the powder into fruit juice, protein shakes or your favorite weight gain formula Made with Pure L-Glutamine

    helps in recovery
    scottchain - 9/19/2014 This product really helps me recover from my intense workouts, with intense DOMS. I have felt quite a difference in recovery times between adding this into my diet and before when was not taking any. Big difference. Takes my body less time to recover with it than without it.The taste is not great but I never drink it with just water. Always in my protein shakes as a recovery and right before bedtime where recovery and rebuilding of muscle actually takes place. This product is highly recomended.
    high quality
    scribbles37 - 9/17/2014 High quality product just as you'd expect from ON. Adding this to my protein shake considerably decreases recovery time considerably.
    helps with recovery
    ntrenc - 9/17/2014 Helps with recovery but not an essential supplement in my opinion.
