  • Growtein™ Lean Mass Gainer



More Gain. Less Pain.

Our most advanced and complete muscle recovery whey protein powder blend.

Growtein™ is a Whey Protein Isolate (WPI) & Whey Protein Concentrate (WPC) blend that has been the keystone recovery protein of our most competitive and extreme athletes for over a decade!

We took 2 whey protein sources that absorb at different rates in the body and carefully added a precise dose of free-form BCAA's, L-Glutamine and Creatine Monohydrate.

Together, this formula appeals to a vast array of functions in the body such as muscle energy, muscle and cell detoxification and muscle recovery so that you get the most out of each workout.

Product features and benefits:

  • 30g of WPI and WPC to assist in intracellular muscle recovery
  • Fortified with free-form BCAA's, L-Glutamine and Creatine Monohydrate for a complete spectrum of amino acids
  • 45 servings per bag so that you can find your sweet spot for the ultimate recovery ratio for your body!
  • 5 delicious flavors to satisfy any flavor palate!

    If you are looking to actually put on some lean muscle mass and not deal with the fatty lower bloat other products give you then Growtein is where it's at. Candy Bar Blitz is hands down the greatest flavor of all time. Highly recommend for everyone looking to put on some size!

    A friend recommended I try out JBN protein. First off, i was greeted with open arms by the employees, and also to free samples. Each and every staff member seemed very knowledgeable of all JBN products. I purchased the Vanilla Growtein. Tastes much better than most proteins I've come across. I will refer all my friends, and I will definitely be back to try other prodcuts.
