Great protein at a great price
Optimum Nutrition Gold Standard Whey Protein is the best value protein on the market. It tastes great, dissolves easily and has a high protein level. Chocolate Malt is my pick of the wide range of flavours. It must be a popular flavour as its hard to get in 5lb size. Try it by adding 2 raw eggs with 300mls of lite milk, its a meal in itself!

Fast service & Great product!
Ordered on a Monday night and received in Victoria Wednesday morning the same week, the product is fantastic!
