When I get bored with the 'milkshake' type flavors, this is my favorite to turn to!MyBariatricLife on Feb. 19, 2019 for Syntrax Nectar Whey Protein Isolate, Roadside Lemonade
I've been a fan of this product for many years. It is refreshing to be able to drink protein that doesn't taste like a shake. The lemonade is my favorite flavor.Jess_d on Dec. 12, 2017 for Syntrax Nectar Sweets Whey Protein Isolate, Chocolate Truffle
