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

I have tried a lot of Whey and this one is the best total package I have found
Flavor Name: Double Rich Chocolate Size: 5 Pound (Pack of 1)
This Whey Protein is not the best tasting, least expensive or most nutritious, but it is the best balance I have found yet of those three things. The taste is good, its price per scoop is good and its nutrition is good. You can find some that taste better. You can find some that are less expensive (and way more expensive too). You can find some that are more nutritious. This is the only one I have found though that was acceptable in all three areas in one product. I should also add that the only flavor I have ever tried is double rich chocolate because most of the time other flavors taste absolutely dreadful and I wasn't willing to risk having a 5 pound tub something that tasted like chalk dust vanilla or dried pepto bismal strawberry just so I could experiment. The double rich chocolate taste is not overwhelming and is not full of too many artificial flavorings (it does have some, but not even close to most I have tried), it mixes well with water and milk, but my favorite is unsweetened almond milk. It also works well in many recipes as a cocoa or chocolate substitute and as a protein kick in various foods such as steel cut oats with some almonds or walnuts. Its taste is not overpowering like many I have tried and that makes it very useful for things other than the standard shaker bottle post workout protein shot. If I had to complain about anything it would be that ON doesn't seem to offer proof of quality regarding the ingredients and nutrition stats. I am not saying they are being deceptive or I have any reason to doubt that there is really and truly 24 grams of protein per scoop with only 1 gram of sugar and 4 carbs or that there is anything I would normally shun, buy why not be up front and in everyone's face about that? Most of the people who order and use this kind of stuff (especially a 5 lb tub of it!) are picky about precisely what they are paying for and ingesting. If we didn't care then we wouldn't be on the internet scouring websites for statistics about various products and ingredients. Anyway, enough ranting because this minor gripe is not enough to keep me from continuing to buy it and it is by far my favorite of all I have tried so far, but if it was my company I would have postings of proof of quality and tolerances everywhere I could stick them just so nobody could doubt it and I could justify charging a little more than some others. Its the best total package I have been able to find so far anywhere. You can get better nutrition and taste, but you have to pay a lot more to get it. ... 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
