I bought the lean protein in Chocolate. The taste is very bland but on the bright side, it is good to mix with other ingredients if you want more flavour. Of course, do shake it very well when you mix it in order to avoid clumping. When you do, the protein will be very smooth and easy to drink. It does make me feel full but I haven't drank it often enough to vouch on whether it helps wt muscle building and/or weight loss. I ordered mine wt the shaker bottle and delivery was fast. However they missed the whisk ball. I inquired about it and surprisingly they sent me the whisk ball with a new shaker bottle. And I received it within a few days too. Totally happy with the customer service.
