I have the 25th Anniversary Dymatize ISO100 70 Servings of Chocolate Caramel and I mix mine with Almond Cashew milk that has 10 grams of protein in it that you can buy at Publix Super markets and also, I mix an egg with it as well and I blend mine in a blender and it tastes Great.👍👍You don't even taste the egg in it, and so it makes it basically a breakfast protein drink to drink after working out at the Gym or just having it with breakfast. If does not have this particular one, then you can find this one at your nearest Vitamin Shoppe if you have one in your state.

I was using Dyamtize ISO for the past 5-6 months. After doing lots of research I bought this one and for me this is the best Whey Protein available on the market. Initially I started with Gourmet Chocolate flavor which was good. Then I switched to Fudge Brownie which is too sweet for me. I had to mix atleast 300 ml of water to get rid of its sweetness. After completing 2 bottles, I switched to another brand suggested by some friends which was a Whey Concentrate.. My Bad !! Used it around 4-5 days.. Suffered from severe bloating, stomach cramps etc..Stopped it !! Again I bought Dymatize ISO now with Gourmet Vanilla.. This is the best for me..Very good taste, low sugar and carb content..easy digesting.. Those who have sensitive stomach this is the best option..this is the purest form of whey protein according to me.. Planning to continue with this brand only ..

  • 10 Orange Ice Cream
  • 3 Chocolate Peanut

I have been using this for sometime now. Orange ice cream is by far the best flavour I have tried. It's light and delicious. I mix it with banana and water. Adding mixed-berry flavour creatine make sit taste even better!! Chocolate peanut was a let down sadly. It tastes more chocolate than peanut. I get bored of chocolate flavour as it is too strong and heavy. This one tastes nothing like a peanut butter flavour. I wish they did the real peanut butter flavour.

  • 9 Vanilla

Good product but does not mix well and the vanilla taste was just okay - maybe a 6. No gas or stomach issues. I have a finicky digestive system so I wanted a good quality protein. Started mixing 2 parts ISO-100 vanilla with one part Elite Whey cookies & cream in low fat 1% milk and now gets a 10 rating for flavor and overall use.

I've been using Dymatize ISO100 for around 3 years straight now. Recently, when they released their "Clear" line, they seemingly changed the formula across the board. I find that none of the Dymatize ISO100 I've purchased in the last 6 months mixes well at all. It almost seems as if the formula is bordering on water resistant/water proof, as it now tends to clump or leave dry power deposited in my mouth piece or along the sides. I've reached out to the customer support, so I'm waiting to hear back, but the line is practically unusable now. It takes upwards of 10-15 minutes of attention to get it to MOSTLY mix.

When the product arrived it arrived in good condition and sealed. There is a paper seal underneath the cap which is nice. The product is not old and smelled fine. So this wasn't some old product sitting on the shelf from what I can tell. Just started using this product. 1 serving about 60 grams mixes nicely in about 15-20 oz of milk or water. The flavor is great. Taste just like BDay cake. My one issue with the flavor is that it is slightly too sweet especially with milk. I can see it probably being just perfect with water though. Digestibility. So far it hasn't upset my stomach or had me rushing to the bathroom. If anything it may cause the exact opposite. (That's protein shakes for you) At least for me. I'm actually lactose intolerant and I haven't noticed any terrible signs of lactose issues with this product. I think this product if it has lactose is very negligible or near zero. So if you have lactose issues you may consider trying this product if you can't find anything else. YMMV though. Overall great product my after workout shake consists of the following for those curious 20oz of 1% milk 220 calories 20g of protein 2 scoops of this - 220 calories 50g of protein 1 Tablespoon of extra virgin olive oil 120 calories 5g of creatine Some turmeric for anti inflammatory Overall 70g of protein and 560 calories. Pretty dang good. Overall try this product I think you will like it.

Good product, Gourmet Vanilla is the best, but although it's 100% whey isolate I still suffer from lactose intolerance symptoms with it

I have been buying Fudge Brownie for quite some time. It has been my favorite for a long time. I just purchased a new 5 pound container recently and I dont feel this one mixes very well. I have never had this problem before, but this batch clumps up. Hopefully this is a one off.

  • 3 Fudge Brownie
  • 6 Chocolate Peanut Butter

Dymatize iso-100 is a fantastic product however the flavors that I have tried so far are not so great. I currently take this product as well as ON Pro Gainer - chocolate which has a great flavor. I believe both to be high quality products that I will continue to take. I am just not a huge fan of dymatizes flavor profile. The chocolate peanut butter is a little too overwhelming but those who like a strong peanut butter taste will probably like it. The fudge brownie however taste like play doh smells with a sweet after taste of sugary fudge. I have 5lbs containers of both which I will continue to drink however I will not be ordering either flavor in the future.

This comment is not to advertise this product in any form!! but I honestly have tried it and it is Fantastic! It mixes great with water, no stomach discomfort and the flavor is amazing! Now I know it is kinda pricey but believe me you get what you pay for and I will definitely buy another one!

  • 10 Orange Dreamsicle
  • 9 Chocolate Peanut Butter

ISO 100 has been a great solution for me. Easy on my (lactose intolerant) stomach and tastes great. Mixes very well in water and my personal preference coconut milk. My first purchases were Chocolate Peanut Better and Orange Dreamsicle. I find the Chocolate Peanut butter to have a really strong peanut butter taste. If you enjoy that kind of strong flavor then it's really tasty and I recommend it. The Orange Dreamsicle has a more subtle taste and was my personal preference between the two. But both are really good and I would buy them again in addition to trying a number of additional flavors as well. If you have a sensitive stomach like me or are looking for a qulity ISO that tastes great and mixes super easy then I would definitely go for this one.
