While it may have only been just a few short months ago, that Muscle Pharm confirmed three new flavors for their Arnold Schwarzenegger Series protein Iron Whey. All of which have been launched for both the 2 and 5lb sizes, and can now be found in most Muscle Pharm stockists. It turns out the brand have one more taste on the way for the whey protein solution. Set to join the supplement’s five piece menu of chocolate, vanilla, cookies & cream, strawberry banana and peanut butter cup. Is a slightly more simple spin on one of Iron Whey’s more recent additions, with banana swirl. Like the others, the flavor is set to hit both volumes of the product, and despite Muscle Pharm not giving any indication as to when the supplement’s sixth will arrive. If it’s anything like the last three Iron Whey’s, banana swirl could be here within the next month or two.
