Very good product

So far, this is one of the whey proteins that I've tolerated the best. I am lactose intolerant and VERY sensitive to even small amounts. I've had no issues with this protein and my recovery time is much quicker between workouts. I use this protein in overnight oats, so I can't speak to it's mixing ability in liquids.

  • 9 Chocolate Peanut Butter

The flavor of the chocolate peanut butter powder is very delicious, tastes nearly exactly like a reese's peanut butter cup or reese's puffs. I found it to be water if you use over 8oz but nonetheless very delicious, you get no clumps and it tastes really smooth.

  • 10 Orange Dreamsicle

The Flavour is spot on sweet and candylicious. Easy on the stomach and no bloating as so ever. Great amino profile as well. This is the best isolate protein in the market. I usually do 1 and half scoop in water after my early morning workouts. Mixes well, no clumps as such. Do give it a try with low fat milk as well. This reminds me of the orange candy ice cream during summers.

Best tasting protein! Make it a 10+ with a tablespoon of peanut butter!

This is my first time trying this protein and I absolutely love the Chocolate Peanut Butter. I will admit it does have more of a peanut butter taste. I’m not able to taste the chocolate, which is fine with me. I mix mine with lactose free milk (I’m lactose and tolerant) and it taste amazing! It’s not heavy on the stomach and it doesn’t have that chalky type taste like some protein powders. I will definitely be trying other flavors once I’m done with this one.

Wrote a review couple months ago, and heres an update. This protein is still AWESOME. Nothing but lean muscle gainz, and fast recovery. I mixes well with glutamine and creatine also. Mixes well period. I am keto-carnivore now, so sometimes instead of milk I use almond milk, and omg it is delicious. Birthday Cake was better with almond milk then anything else, but Peanut Butter is heavenly with anything. I will stay getting PB, but will keep trying other flavors as well. ALSO, if you have stomach issues or are lactose, this protein is VERY easy on your stomach. Take it from me, I have horrible digestive issues, but a nice keto-carnivore diet and this protein has me feeling better then I ever have. HIGHLY recommend. I have been using this protein with my new keto-carnivore diet, so far its been about 50 days. Combined I have lost 9 lbs and 12% body fat. At a lean 182 10% bf now for summer! Cheers!

While this dissolved well in water and the chocolate peanut butter taste itself wasn't bad, I hate the sucralose taste. The nutrients seem good otherwise.

  • 10 Gourmet Vanilla

I was surprised at how well this tasted compared to my last vanilla protein shake mix. Mixed up easily in my shaker and had a nice creamy vanilla texture to it. Will definitely get it again.

I've commented below on other flavors and why Dymatize is my go-to protein. Recently tried some new flavors. Chocolate Coconut - Was a bit too sweet and artificial tasting and for some reason every time I drank it, it would give me an upset/sour stomach, which has NEVER happened with any Dymatize protein. Orange Dreamiscle - I was excited to try this flavor because it had great ratings and a lot of hype but in my opinion, it was just ok. Less sweet than other proteins I've had from Dymatize and for about an hour after drinking it ever burp was an Orange Dreamsicle burp. Chocolate Peanut butter is hands down still my #1 pick and what I will most likely be going back to after experimenting the last 2 months.

  • 8 Fudge Brownie
  • 10 Chocolate Peanut Butter

After about of month of taking this protein I have to say the peanut butter chocolate is by far the best tasting protein I’ve ever tried.. I go nuts for anything peanut butter but this tastes kinda like the little Debbie nutty bars makes for a perfect little treat after the gym.. the fudge brownie tastes like licking the spoon of batter but I’m not a huge chocolate fan although the flavor still tastes great.. will continue to buy this because it’s the easiest isolate I’ve tried and the best tasting one
