    • Great Stuff!
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
I previously have been using another popular protein powder. When pricing went extremely overboard, I saw this Optimum Nutrition Gold protein powder at a decent price and decided to give it a try. My 1st scoop of Optimum Nutrition Gold went into the blender with milk. The powder blended well. It was way thicker than the other brand. I was very impressed & satisfied with it's texture. There was zero chaulky after taste. This powder actually tastes like chocolate ! I like that alot. My 2nd scoop later that day was into a tumbler filled with black coffee and once again it blended well, although I mixed with a knife stirring it by hand (I think I could've mixed it a little more but it was still good as it was). It actually made the coffee taste just like chocolate. My other powder came close to the chocolate taste but Optimum Nutrition Gold came out way ahead for is real chocolate taste. No after taste either and just a smooth tasty drink. Overall, after only 2 scoops of trying Optimum Nutrition Gold this is now my new go to protein powder hands down! Not to mention Optimum Nutrition Gold has 6 more grams of protein per scoop than my previous powder that I was using did. The next test will be this powder with water mixed. I'm sure it won't disappoint either. So it you're looking for a protein powder I recommend trying this. I am very pleased with my choice purchasing Optimum Nutrition Gold. 10 Stars if there was room for more stars. Your new customer. ... show more

    • Excellent protein powder! Great quality & taste!
Flavor Name: Double Rich Chocolate Size: 2 Pound (Pack of 1)
I’ve tried several protein powders over the years, and Optimum Nutrition Gold Standard Whey is easily one of my favorites. The Double Rich Chocolate flavor is smooth, rich, and not overly sweet or chalky like many others. It mixes easily with both water and milk without clumping, and the texture is creamy. Each serving provides 24g of protein, making it a great option after workouts or when I need a quick, high-protein snack. It keeps me feeling full, helps with muscle recovery, and doesn’t leave me feeling bloated. The quality, taste, and value make this a product I’ll continue to buy. If you’re looking for a reliable whey protein that actually tastes good and mixes well, I highly recommend giving this one a try! ... show more

    • My favorite flavor!
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
I’ve tried several flavors of this protein powder, and Double Rich Chocolate is by far my favorite. I wasn’t a fan of the Peanut Butter flavor because it was too sweet for my taste, but flavor is personal, so your experience may be different. The protein itself is excellent. It mixes easily, has a smooth texture, and tastes great in shakes. I’ve been using Optimum Nutrition for a long time, and the quality has always been consistent. If you’re not sure which flavor to choose, I highly recommend giving Double Rich Chocolate a try! ... show more

    • Great Taste, Easy to Mix, and Perfect for Daily Protein
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
Great taste and mixes easily! I’ve been using this whey protein regularly, and so far I’m really happy with it. It mixes well with water or milk without getting too clumpy, and the flavor is good without being overly sweet. It’s also been easy to incorporate into my daily routine, especially after workouts. Overall, a solid whey protein for the price. I would definitely recommend it if you’re looking for something that tastes good, mixes easily, and is convenient for getting extra protein throughout the day. ... show more

    • The flavor is not that good...buit the Vanilla Ice cream is just great!!!
Flavor Name: Double Rich Chocolate Size: 10 Pound (Pack of 1)
The flavor is nothiong spectacular. in fact, with water, it's close to terrible. I think im getting used to it but at the beginning it was very bad. With milk the flavor is OK though. I have only been using it for a couple weeks now (3maybe) and during this time i have gained a lot of mass. I cant say it is solely becaus eof it but it has helped me maintain a very good macros ratio. My protein intake has gone up. Now i am not losing any weight but it is because im getting a lot more protein and am building more muscle mass than before. The product seems to be very good, but i honestly dont have enough time with it as to give a proper rating about its mass building capabilities. It seems to best protein bang for the buck though. 4 stars because i didnt like the falvor too much. I understand the extreme milk chocolate is better than this (double rich chocolate) but it doesnt come in 10pounds bag. EDIT. March 25th., 2008. This is my second review of the product. I gave 4 stars to the previous one. NOw i feel like upgrading to 5 stars. It was the double rich chocolate flavor. I think the product is very good even when i dont have any reference to compare, since i havent tried any other brand. I ordered along with this whey, a syntha-6 and a ON casein protein. They are both supposed to be great products, with syntha6 being considered the best tasting protein power out there. Some say Muscle milk is better, but apparently is a close race. I felt the need to do another review because of the great taste of the Vanilla Ice Cream flavor and because having taken 10.37pounds of the product i feel i could definitely comment. After being in a very long diet I have lost more than 65pounds in exactly a year. Even on a caloric deficit Ive managed to build a few pounds of lean mass and I must say I am convinced than supplementing with this product has been a key factor in this success. After I started taking it i noticed a difference in the time i needed to recuperate from workouts and aybe it was just timing but I am looking more muscular than ever. Also, the truth is that I wasnt having near close to enoguh protein before i started using this product, so what i mean is that this is just protein, and it will make your life much easier when it comes to proper dieting and having enough protein every day. If you are concerned about taste, you cant go wrong with the Vanilla Ice cream one. It is so good that after my first cup of milk with 1.5scoops I felt the need to come here and share. With water it is not good, but what is it? Even nesquick taste like crap with water...it is a great product. Remember, have at least one gram per pound of bodyweight...do that and it will be really hard for you to be on calorie surplus, then you'll lose fat. ... show more

    • Amazing taste and good source of protien
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
Good flavour. It's not too chocolaty and not plain as well. I drink it with milk and sometimes water. It takes time to get used to the taste with water but after that it's amazing.

    • Delicious!! My whole family loves this!
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
Review Image by Sara V.
I originally bought this for my husband and me, but now our whole family uses it. My kids are ages 3 to 11 and I give them about half a scoop mixed with milk to help with protein. They honestly think it’s a treat and say it tastes just like chocolate milk. They have no idea it’s protein. My husband and I each do a full scoop with a glass of milk every morning. It’s an easy way to start the day and actually keeps us full for a while. It mixes really well and doesn’t have that chalky protein taste that a lot of other powders have. That’s been the biggest thing for us. The only small thing is sometimes I have to work a little to stir out a few chunks, but that may just be a me problem and how I’m mixing it. We do go through it pretty fast since everyone wants it, but it’s been worth it for our family. If you’re looking for something that tastes good and is easy to use for both adults and kids, this has been a great one for us. We searched for a clean, healthy choice that tastes great. This is what we landed on and it's been great! ... show more
