It was only last week that Marc Lobliner announced the coming of his fourth MTS Nutrition Whey flavor, which is now available from Tiger Fitness. The latest taste to hit the Protein Wars runner-up is peanut butter fluff, giving MTS Whey the full set of non-fruity common flavors. The usual cost of the protein powder is $52.99, a value that has unfortunately not changed for the arrival of Lobliner’s peanut butter variant. For those of you who get their MTS supplements outside of Tiger Fitness. The product’s fourth option is expected to eventually hit places like Muscle & Strength, however there is no word on when.
