Following on from last week’s launch of Grenade’s all new version of its pre-workout .50 Caliber. The brand’s other new supplement is also now available, the US edition of Grenade Defend. For those that missed our post on the product, the amino formula is quite different from the original being more BCAA based as opposed to a full blend of amino acids. The supplement can be picked up from the same place stocking the reformulated .50 Caliber, the retail giant GNC. The store has priced Grenade Defend at $32.99, or $3 less for Gold Card members at $29.99. GNC has both of its flavors in stock, with both Strawberry Mango and Green Apple available for purchase.
