Chocolate Coconut - So this one was weird for me at the beginning, I felt like I really didn’t like the taste. Now I must state that I am not a huge coconut fan but love the Coconut Crème Elite Bars so I figured I’d give it a go. So like I said, in the beginning I wasn’t sure I liked it at all but now that I’ve used it for a month I really enjoy the flavor. If I would have just gotten a sample I am sure I would have never bought a tub. ISO-100 is and has always been easy on my stomach and with low calorie and 25G of protein it is always one of my favorites!! Just for the record my favorite flavor ISO-100 is Rocky Road and my least favorite is the Birthday Cake and this one falls pretty much in the middle for me. Banana - LOVE, LOVE, LOVE the ISO-100 Banana. I don’t know what else to say, I would put this right next to Orange Dreamsicle (my second favorite). Now I did take one scoop of Chocolate Coconut with one scoop of Banana and it was amazing. It really gave life to the Chocolate Coconut!!

This is an amazing protein. Really great profile and some really great flavors. Mixes extremely well and is versatile when it comes to mixing with milk or water. I love how you can make it fit into any type of daily macro totals. It is usually the #1 protein I recommend to all of my friends when they ask for options.

Probably the best protein powder I've had in a long time. It dissolves easy and tastes good enough. i am not looking for taste. i am more interested in the quality (1) digestion, (2) texture, and (3) price. It's all good. I usually mix this with Synth whey protein and it's just great. I highly recommend this product.
