Optimum Nutrition Vanilla Casein

Been using ON Casein for years....never disappoints. I like to add (along with some vanilla whey) to my cereal. Helps to make a junk food somewhat healthier.

Regarding Supplement Source, first time I have purchased from them. They offered the best price in Canada plus free shipping ...had my product in a couple of days. I will definitely be back to shop for more supps from them.
