Fans that have been waiting to try the first new flavor for Muscletech’s hit protein bar Mission1, can now finally get their hands on it. Following its confirmation from back in late April and several teasers of it since, the Chocolate Peanut Butter Mission1 Bar is now available for purchase. The supplement’s fourth option has shown up first at the retail giant GNC where it’s currently a little more expensive than the original flavors. The prices on a box of Chocolate Peanut Butter Mission1 are $28.79 for Gold Card members and $35.99 for everyone else, which are $4 and $9 more than the other three.
