AI Sports Nutrition has introduced a way for fans to try all five flavors of its protein powder simply titled Whey Protein, at a heavily discounted direct rate. At the moment you can pick up the supplement direct from the brand for $39.99, which is only slightly more expensive than stores’ price of around $35. Where the variety and discount comes in is AI has put together the Ultimate Protein Pack made up of Whey Protein in Chocolate, Pumpkin Pie, Birthday Cake, Mocha and Cinnamon Roll, costing just $124.99. Basically the brand’s stack works out to $25 a 2lb, saving you $15 per tub or $10 compared to store pricing. The only real catch is that you have to get one of each flavor as AI doesn’t allow any substituting.
