I took this product along with Creatine Monohydrate (XXL Nutrition). First of all I really liked chocolate flavour of this mass gainer, much better as Serious Mass for example. Along with the Creatine product I gained about 3,5 kg's in the past 4 weeks. Thanks a lot XXL Nutrition, I finally found a shop with reliable quality and competitive prices. I will surely visit your shop again!
