This is the only protein powder I've tried, as Optimum Nutrition was highly recommended to me as the "gold standard in protein powders" by several weightlifting enthusiast friends of mine. Luckily, the first flavor I tried, Chocolate Malt, ended up being amazingly delicious to me, so I never had to buy and try any others -- though they have so many different flavors, I'd like to try some of the ones that sound good, such as the coffee, the vanilla, or the mint chocolate flavors. Anyway, I use whole milk and drop a spoonful of this whey powder in a Blender Bottle, shake the crap out of it, and enjoy it after lifting.

This powder blends REALLY well *with a Blender Bottle*, and I rarely get clumps/bubbles of dry powder. I tried using a spoon and stirring once, and got tons of clumps. This powder is packed full of protein, as it contains a form of whey that packs more protein per volume when compared to regular whey which some protein powders use, which means you have to use more of those powders to get the same amount of protein as you would with Optimum Nutrition's. This product also contains a bunch of the BCAA (branched chain amino acids) that the human body requires after exercise in order to repair/build muscle. The only thing this powder lacks is ingredients for muscle recovery (chiefly, my favorite, L-Glutamine), things regularly found in nighttime/overnight muscle recovery/repair formulas. This product doesn't need it, but it would round it out as the perfect after-workout protein powder if it had L-Glutamine in it (but that would be unnecessary if you lift/drink these in the mornings). Instead, I just add a spoon of pure L-Glutamine powder to my Optimum Nutrition shakes and I'm good to go! Anyway, obviously, I really, really highly recommend this brand, this product by them, and this flavor of whey protein powder for all your "gain" needs -- Get those gains!!! 🏋🏻‍♀️

I've used this several times because it's been recommended by several friends and can easily be found at Costco. I only use the chocolate flavored one as I don't care for any of their other flavors. However, I've started and stopped using this several times because I don't think whey sits well with my GI tract. It upsets my tummy in all sorts of ways (gas, bloating, upset stomach). I stopped using it for a while to try other protein alternatives, to which I have the same or similar experiences. I just think my body doesn't do well with protein powders. But if they work for you, this is a pretty decent one to have.

I've been trying to gain weight for about 4 years, being 5”10 and weighting 150 lbs and I was very skinny for my form, I had decided to go hard this time and my gym friend recommended this particular powder over other ones I had been previously trying as he said it had helped people with similar issues to gain weight. So I started Gym again with this shake (two scoops on a morning on rest days and 2x2 scoops morning and after gym sessions) and within a week started to notice results. Now results wont just come from gym and this shake if you're like me, I've had to stick between 3500 - 5000 calories daily, with high carb high protein foods (as lean as possible meat) and a healthy side of multivitamins. The result is I gained 11 pounds (5kg) in 4 weeks, which for me ... MoreI've been trying to gain weight for about 4 years, being 5”10 and weighting 150 lbs and I was very skinny for my form, I had decided to go hard this time and my gym friend recommended this particular powder over other ones I had been previously trying as he said it had helped people with similar issues to gain weight.

So if you feel it's extremely hard to gain weight and are looking around, contemplate giving this a try, eat healthy and work out, I can almost promise this will work. It is hard work though, and it will cost a bit more monthly, but I feel better right now mentally and physically than I ever have in my life.

Delicious chocolate flavor
20 March 2023

Drinking protein shakes is part of my daily routine. I have them in between meals and also post workout. The ingredients are the most important thing I am looking for when selecting protein powder. The next most important thing is taste, let’s face it, if it tastes terrible, you aren’tgoing to want to drink it. This powder is gluten free, packed with 30.4 grams of protein in 1 scoop, only 3 carbs and 120 calories! It mixes up smoothly with water or milk (I prefer milk) and has a thick, luscious consistency. I always look forward to drinking it! Definitely recommended!

Excellent!

Very good product. I recommend it. Delicious protein is well mixed with cold milk or water. I drink half portion for half an hour before and half immediately after a workout. Excellent for strength, health, and immunity. The dosage is appropriate. The packaging is attractive. Good for hair and skin. The size is very suitable and good. Contains antioxidants, is healthy, has a super taste, the ingredients are good, and the quality is excellent.

Best protein on the market. For everyone saying the formula has changed... as far as the Double Rich Chocolate I've been getting for YEARS, there is no change as of a week ago (Jan-2018). No Sucralose. Just avoid flavors like Cake Batter, Ice Cream and Banana I ordered the double rich chocolate (DBC), thanks to reviews indicating it did not use sucralose (and it does not as of 06/12/18). I've never used ON before, I do not know if it "used to" taste better. As of 06/12/18 the DBC flavor tastes roughly like burnt brownie flavored cardboard. Thing is, I understand without a SUPER sweetener, it can be difficult to achieve flavor, but be forewarned, it is AWFUL tasting.

Consistency remains almost the same as whatever liquid you have mixed it into (adds no extra thickness). I tried both water and milk. On the positive front, it is jam packed with goodies with every scoop. It mixes extremely well (I use milk mainly) and when mixed with other powders, it continued to mix well (I add extra probiotics and stuff for my joints). I let it sit for a few hours on the counter, everything settled and needed a slight jostle, but (aside from being warm) mixed right back up and tasted exactly the same with the same consistency, which is great as I have had powders that turn to sludge if you let it sit for too long. For the price @5lbs and 30g scoops, you can't beat it. There are better tasting powders and better powders overall, but you can expect to pay $50-$60 for 2lb for those, I find this powder to be an excellent middle ground if you can stomach it, especially with the prevalence of sucralose finding its way everywhere. For those not in the know, please Google sucralose, it won't bother everyone, but if you're like me, it did affect my digestive system negatively and since removing it from my diet I have been doing much better.

Good protein powder but lacks flavor.
20 March 2023

The Gold Standard Whey Protein Powder Double Rich Chocolate is a decent protein powder. It blends up nicely using a blender bottle. It mixes well with milk, water, even almond milk. My only problem is the chocolate flavor. Its just not that good on its own. Its supposed to be rich double chocolate and it doesn't taste like it. I am usually a vanilla guy but I got this flavor to change it up and try something different. Overall its a decent protein powder I think It could just taste better.

Great protein.
15 March 2023

Whey protein has outdone them selfs with there double chocolate protein powder. I absolutely love the taste of this stuff. And another great thing about whey protein powder is you can use it in many different ways. You can add it to different recipes not only as a shake. This product definitely dose the job. Sense i have been using it i noticed i have alot more energy. It also comes with measuring cup so you always have perfect amount for that great taste. If your looking for a great way to get extra protein. I would definitely recommend whey protein double chocolate. It's the best tasting powder i have tried yet. And easy to use and it definitely works great.

Yummy!!!
27 November 2022

This protein is fantastic! I read reviews on it first before buying and I am impressed. Most protein powders that I've bought in the past have given me pretty bad â›˝, hehehe, but this one does not. I also do not make it as a drink, but I do make pancakes. 1 scoop vanilla ice cream powder, 2 T. liquid egg whites, 2 T. water, 1/2 tsp baking powder, 1 tsp cinnamon, a few chopped walnuts. I eat them with blueberries and half of a banana. I did try to add bananas to the mix, but it kind of burnt them. I also make a weeks worth and freeze them. I will either pop them in the toaster or eat them half thawed, half frozen.
