    Great supplement!

    Growtein builds muscle weight nicely. I take every morning before my workout. It mixes well in a shaker cup (no need for blender), tastes great, and since I'm lactose intolerant it doesn't disturb my digestive system like many other supplements. I've been taking this for several years and it's by far the best supplement I've ever taken!

    For great gainz and recovery, I like my Growtein. The flavor of the chocolate can't be beat either.

    Loved the flavor, no chalky aftertaste and provides more grams of protein than most.

    All-Time favorite

    My all-time favorite product. I can get everything I need to improve my size in one shake. All the flavors are delicious, and have great texture (no clumping). This is a lifetime product for me!

    Not only does this taste great, but I also noticed the addition of lean muscle too. I'm very satisfied with this product and highly reccommend JBN as a whole.

    Great product!

    Posted by Mike Meining on Jun 5th 2016

    I started using JBN Growtein a few years ago, wanting to add more muscle, give me more energy in my gym workouts, and avoid the digestive issues I always had with other protein powders. Growtein gives me all those benefits, being especially tolerated by someone with lactose intolerance. I like all the flavors, chocolate is my favorite, and they mix as well with water as with milk in the hand shaker..

    Most women are afraid of the Growtein, but the staff at JBN made me realize its the PERFECT protein for the type of training I do. (Kick boxing, Crossfit and Spin) They explained how the creatine is the perfect amount to replenish what my body was depleted of! I have been taking it for about 2 months and FEEL amazing.
