Absolutely fantastic! I bought 2 containers of orange dreamsicle and I LOVE IT. True to taste. Not only is it perfect after a workout, but it is also perfect when you’re craving something sweet! I can’t wait to try the other flavors

This protein powder was delicious! Mixes really well and was not too sweet. It took everything I had not to drink one right after the other! Can't wait to try other flavors

Very easy to mix and taste pretty good with water, no bloating or any side effect for me, good macro's, so overall this is pretty good. Of the 3 flavors I've tested so far, I like Orange Dreamsicle the best (I'd see myself buying a bigger tub). Birthday cake taste's a bit too artificial, tolerable but can't say I agree with high user rating. Gourmet chocolate taste awful. I love chocolate of any kind, but this doesn't taste good at all, I'll be very happy when that tub is done.

  • 9 Peanut Butter

Mixes great, very authentic and subtle peanut butter flavor.

  • 10 Peanut Butter

Great taste! I've been using it for 3 days now and i could say that I recover quick from my workouts. I used Syntha 6 before then switched to NitroTech. I hope this one gives me better results. I used it twice a day. 1 scoop in the morning upon waking up, and 1 scoop for my post-workout shake. I only mixed it with 8oz of water. It mixes easily with water but the only thing I noticed is that, upon shaking, its 80% shake, 20% foamy.

By far the best protein. Whey isolate at its finest. Short list of ingredients and no fluffers. And the taste!!! Incredible. Orange Dreamsicle is my favorite. So refreshing and always look forward to the taste.

By far the best protein mix I have had. The Chocolate peanut butter one tastes like a Reese's cup. Look forward to drinking it every day!

I recently tried the new Chocolate Peanut Butter. At first, I was going to wait until I finished up the "Natural" Vanilla I had left. The Chocolate Peanut Butter flavor is outstanding in comparison. So I didn't endure. See below. On Mar 22, I wrote this review on the "natural' natural vanilla flavored IS 100: I do not know how Dymatize can get "natural" vanilla so wrong on their ISO 100 Whey product. Their Elite Casein smoothe vanilla is spot on. How could a company make those two products and not detect the magnitude of difference in taste? The "natural" vanilla taste in their ISO 100 Whey is bitter and leaves a horrible aftertaste. The product also clumps which is surprising given they beautifully fixed that problem with their Casein years ago. I use these products daily and love their Casein and endure their Whey ISO 100.

I love this protein! I wish I would’ve tried it earlier. I don’t bloat or get weighted down with indigestion, even when double scooping for 50g of protein when I’m on the run. Excellent product!

BDay cake was a flavor thats highly talked about highly by the good forum bros so it certainly had a lot of hype coming in. Needless to say, it certainly lived up to the hype and even exceeded it. The Bday cake flavor was enjoyable in the multiple ways tried and shined throughout. My only gripe was it didnt have sprinkles lol. The cinnamon bun flavor certainly lived up to its name tasting like the liquid version of the cinnamon buns I use to get from the mall. I could even tasted the frosting with it as well. Definitely one of the top cinnamon roll versions ive tried and definitely the best iso version of it hands down. The cookies and cream was a flavor that shined well with dairy products (milk and cottage cheese) and even water, but with oatmeal it didnt stand out. The pancake still needs to be retested. I wouldnt put it in my top 3 cookies and cream flavors I had had but I would recommend if someone was looking for that flavor in an ISO. Fudge Brownie is one of the top chocolate flavors ive ever had. It literally tasted like a liquid version of a brownie out of the oven. My favorite way to enjoy was in milk but im excited that it taste awesome in water as well since it will be a nice sweet treat I can enjoy when I get deep in my cut. Would heavily recommend. Orange Dreamsicle certainly lived up to its name as well as the hype. I got a nice 50/50 balance of the orange and the cream flavor throughout the different usage. My favorite was to enjoy it was in milk but the other ways were pretty tasty too. Ill have to redo the protein pancake but I also plan on make some smoothies using this flavor as well (will post pics too). Overall, well done on the flavor Dymatize. Smooth banana was good flavor in shakes, in cottage cheese, and In oats, the flavor wasnt as strong. All in all I was pleased with the banana flavor. Gourmet vanilla was a good tasting flavor vanilla. It was good in milk and water, but also shined in oats as well.
