I ordered this protein because I got a rocky road sample along with my order. I thought I'd give it a try. Then, I saw the reviews for the gourmet chocolate Flavour. Honestly, I have the rocky road and former chocolate.... I CAN'T tell the difference. It tastes the same to me. Tastes good. Mixes extremely smoothly.

I take the protein powder with my morning cereal to increase my daily protein intake. I'm not really a "postworkout protein shake" kind of person. I tend to feel more hungry and eat more after drinking a shake after my workouts so I find my protein cereal more filling and keeps me full longer. Taste: 10/10 It tastes exactly like one of those rocky road icecream but leaning more towards a more chocolately flavor. Mixability: 10/10 No foams, no clumps, easily dissolved when mixed with water. Mixing with 200-250ml of water hits the right sweetness and consistency. Effectiveness: I noticed more definition and more lean muscle gains. But of course, it could have been due to my regular workouts and other factors e.g. nutrition, consistency, etc. Overall: I'm very happy with the product and I hope to try more flavors in the future.


Noticed that I was able to recover from my soreness real quick using this product.


It has been hard for me to build muscle on my own. After I tried this product it has helped me a lot I am very satisfied with my results.
