Mass infusion not only delivers results, but at the muscle and strength site you get the best price. Muscle and strength is the best site for supplements and training information.*

Absolutely HORRIBLE!!! Does not mix well in milk or water. Remains clumpy. Flavor is also bad. Maybe the product is too old not sure but extremely disappointed!*

Flavor is fair, mixes great, tastes a little like chemicals though... Not worried that much about the California cancer, birth defects warning on packaging. At least it tells you, instead of hiding it, like most supplements or foods do. Fair price. I will know more with results after i drink my second bag!!!*

I love the taste. I don’t use this as a mass builder. I use it post workout, I put one scoop on top of a scoop of whey protein, and blend it together for extra carbs and calories. It taste great.*
