I'm a huge fan of ON and this is one of my favourite products in the lineup. The Mocha flavour tastes amazing. I compare it to the flavour of a Coffee Crisp chocolate bar when mixed with unsweetened almond milk. Definitely my favourite meal replacement on the market - both in flavour as well as for keeping me full. I have found that adding ON's Amino Energy in Iced Mocha Cappucino to this shake makes it taste even more amazing, and gives me that extra kick of energy. I start every single day with this combo and now can't live without it! Please don't ever discontinue it :)

I love ON products and this is right there with their quality. The taste is amazing and texture is so creamy. I love this meal replacement shake. It keeps me full for about 3-4 hours and tastes so great it's like having a dessert for breakfast. I've tried several meal replacement shakes and this one BY FAR is the best!

I use this for breakfast before hitting the gym in the mornings and it fills me up and gives me the carbs I need to complete my workout. Really great taste compared to other plant based products.

I absolutely love this product! The protein along with the carbs help keep me fuller then a normal protein shake and is a super easy meal replacement when on the go!

There are many meal replacements out there, but not one like Optimum Nutrition's Opti-Fit. There are many days at work I'm out in the field and there is absolutely no other food options for me; Opti-Fit is a quick, easy, and conveinient way for me to get quality nutrients in while I'm on the go without hurting my physique goals. The taste and texture are amazing!

I have both the chocolate and the mocha and they are both great. They have been really helpful as meal replacement shakes as I've been missing lots of meals due to work. This MRP shake keeps me full but not bloated and are far less calories than a fruit smoothie and a lot more protein! Definitely my go-to lately.

I just got the chocolate and the mocha and am really surprised about the previous review because I was in shock at how good both of the flavors are! I do, however, make sure to only add about 6ounces of water (to any of my protein shakes) to not water down the flavor otherwise I can't stand the taste of most of them. I really like these and I love how they have carbs, so good for you post workout to get in carbs (not just protein).

This product, as expected, is delicious! I blend it up with water a bit of cashew milk and a couple ice cubes and it makes for a great tasting shake that can satisfy any sweet tooth! And it's perfect for us moms who struggle to get breakfast in while trying to get the kids ready and out the door for their day!! Thanks to this little gem I actually got to leave the house a few minutes earlier than usual! Seriously a winner in my book!!

Highly recommend! This new meal replacement shake is for anyone trying to get their daily protein in while staying lean and fit. Mocha is my favorite flavor so far! :)

I was excited to see that optimum nutrition was making a MRP and i ordered it as soon as it was available. The chocolate flavor of this was a let down. Look i'm not saying it's horrible, i'm just saying you won't ever brag about it ever. It's like drinking nesquik's broken dreams. The mrp itself isn't that filling and overall this was just a disappointing product by a company that has some great products.
