It’s 2015, and if getting fit and building muscle mass is on your resolution list… then you’re going to need this…

Costco once again has a 2.2kg tub of Kaizen 100% Whey Isolate Protein on sale for $38.99 (regular $48.99). With 35g of protein, it has the best bang-for-buck and beats out all other named-brand proteins when it comes to content.

It’s available in Vanilla Ice Cream and Decadent Chocolate flavours. I’m not a huge fan of the Vanilla flavour but the Chocolate is delicious.

Price is valid until Sunday, January 18, 2015.
