The product I reviewed is ON gold standart 100% whey, Mocha Cappucino Flavor.
I mixed It with milk, It mixes O.K (a bit of powder residue on the side of the shaker sometimes) but Overall it mixes alright. The taste on the other hand is amazing. With milk It taste similar to a starbucks frappucino or a Tim Hortons Iced cappucino. Perfect balance between sweet and unsweetned.
The product itself is protein, So I can't speak over muscle/strenght gain, it is just a food supplement.
