Amino1’s 15 and 32 serving bottles have been making the rounds at a number of retailers with a 3 flavor menu. Fruit punch, cherry limeade and lemon lime. As mentioned in the review, Muscle Pharm are going to need more flavors, sizes and unique variants to push sales for the supplement. Surprise, surprise, GNC have just started to stock a 50 serving tub in all the flavors plus orange mango. The new taste is available in the 32 size bottle as well. Whether or not these variants are exclusive to the retail giant is a mystery.
