Great Taste & High Protein – Just Wish It Came in a Bigger Size

Really impressed with the Max Monster Protein. The taste is great not too sweet or artificial like a lot of other protein powders. It mixes well and doesn't leave ann aftertaste. Love that it's over 80% protein per serving. Only downside is the size, would be perfect if it came in a larger tub like the other products. Otherwise, no complaints. Will definitely keep buying.
