Mass Results

Happy with the purchase. Was able to put on a few kegs whilst training. Other proteins weren’t quite getting me to the weight I wanted

Mass protein is a good supplement if you want to gain weight I only drink one a day helps me. I don't get bloated or anything like that I recommend it. taste good too.
