I have to start by saying every flavor this company makes is FANTASTIC. I have tried countless types of protein over my years of "body-building" at an amateur level. I have probably consumed 300+ tubs of protein in my life and plan to continue. I don't know how Xtreme Formulations makes their product, but in my opinion it is one of the most effective products when used in combination with a healthy (in my case organic) diet.
But above all that, the flavor is unreal. The Cinnamon I purchased here on Amazon, I use that to put in my oatmeal in the mornings, just plain rolled oats and half a scoop of this powder and WOW. Now it is a bit unusual, but if you like cinnamon you can learn to love this with oatmeal and many other mix-ins. Not to sell it short on it's own, just mixed with water it is fantastic, and you don't get tired of it like you do with regular chocolate and vanilla powders.
Also, just as an aside, do yourself a favor and check out the LEMON CREAM PIE, you won't be sorry, it is hands down the best of any protein I have tried, I have used it for over a year, almost daily, and I still look forward to it every day. That is not easy to say about a protein powder. Amazon is a bit confusing, both of these should be the Lemon Cream Pie, I would choose the one that says Ultra Peptide 2.0, although I bet they are the same:
