I have been drinking the cinnamon bunn flavor for over three years now every morning. I mix with milk, a banana, 1 tbsp of peanut butter, little bit of plain oatmeal, and a tsp of local honey and blend it in my nutribullet. EVERY morning. Thanks Optimum Nutrition and Bodybuilding!

Only had the chocolate as my local supplement store had these for $9.99 a bag and I bought them all after trying it. Super good! Gives me a nice energy boost in the mornings. Good replacement for coffee.

Super good product. I love the cinnamon bun taste. I haven't tried any of the other tastes because I like the cinnamon bun taste most. Prices jump around a lot for this product. It goes from 15 dollars per bag to up to 28 per bag. If you wanna buy it, wait for a cost of 15 to 20 per bag. Its worth it then. I like the caffeine in it. I take three scoops with water or almond milk in the morning. Careful to not use it throughout the day or you'll get used to it. I wouldn't recommend it as a pre-workout, only as a replacement for coffee with protein in the morning with much better taste.

I have tried many different protein powders and this is DELICIOUS! I am a chocolate lover, I get very disappointed when chocolate tastes fake or just is lacking in flavor. But THIS is seriously so good. It's freaking SMOOTH, mixes so well (i've used water and straight coffee) and tastes EXACTLY like hot cocoa. I just recommended this to a friend. For the price, number of servings, amount of protein, calories and just overall taste... THIS is my new favorite protein!

I love this flavor. 10/10! I drink this in the mornings for an energy boost and sometimes mid afternoon for a pick me up. Definitely has great flavor and easy to mix with milk or water.

Spent some time trying this stuff out, and 3 stars is the best I could come up with. The powder itself has very little protein compared to a generic protein powder. The caffeine amount is little to none. My biggest complaint of this powder is its inability to mix. I tried to mix it with milk and hot water. It just won't mix and remains clumpy. Your only option for mixing this powder is in a blender. The Mocha Cappuccino just tastes like a tangy, underwhelming cocoa mix. The Chocolate actually tastes superb, again, this was after spending 20 minutes making it drinkable. Unless you like pounding down a scoop of powder, this is by far the worst bag that ON has put out. I am going to pass on this until ON improves on the blend.

Go to protein energy as a UPS driver. Drink throughout the morning for a little caffeine boost/protein supplement. Every single flavor is absolutely phenomenal! I originally found this product when I was looking for a coffee protein and because of that Mocha Cappuccino and Vanilla Latte and my favs!

4 years later and still the best protein i have ever had. Taste and effectiveness. They discontinued this a while but very happy it is back! This protein needs more credit, seems like not many know about or appreciate it. Hopefully there will be some sales soon as well!

The mocha cappuccino flavor doesn't have a strong coffee taste, but it still has a delightful chocolate taste to it. The cinnamon bun flavor is really sweet, and the taste does resemble a cinnamon bun. I tried both of the flavors in milk and chobani greek yogurt. Overall both of the products dissolve easily and tastes delicious, and I would recommend others to buy it and give it a try!
