What customers say about "Key Specs"
Ultimate Nutrition Prostar 100% Whey Protein Powder - Low Carb
  • I have been taking protein now for years and this is truly one of the best I have ever used! I mix it in with my oatmeal every morning and has no problems with clumps or a chalky taste.
  • One of the most budget-friendly whey protein options has also an array of great flavors.
  • Cheapest straight protein/amino-acids powder I've ever seen. Works awesome and tastes great too!
  • Love this protein! it breaks down easy and never have problem with lumpiness.
  • Wow!! Really great taste, It's my new favorite protein. It's loaded with essentials. I thought the banana flavor was good, the chocolate is really amazing.
  • It wasn't too sweet, it had a decent, if a bit thinner consistency, at recommended ratios.
Optimum Nutrition Gold Standard 100% Whey Protein Powder, Double Rich Chocolate, 5 Pound
  • Quality product, few ingredients. High percentage by volume of protein per serving.
  • The price vs volume vs protein per serving ratio can't be beat. Very happy with my purchase.
  • This product has the best volume to price ratio I could find. It tastes great, and it really seems to help.
  • Optimum Nutrition definitely manufactures quality supplements and this is probably their highest volume product.
  • Double chocolate flavour taste really bad!! Please don’t buy it. It used to taste very good but I don’t know what happened.

What customers say about "Amount Per Serving"
Ultimate Nutrition Prostar 100% Whey Protein Powder - Low Carb
  • Protein-wise, it's a pretty good deal. Less pricey than my favorite protein powder (Isopure Zero Vanilla) but with about the same protein content.
  • It also packs a good amount of protein, which is, of course, its goal. Just make sure not to blend it with excessive water, as it will feel incredibly diluted.
  • Have been using it for a couple of years, both in my home country and here. It's the best value for money reliable whey protein in the market i.e. max amount of protein per dollar.
  • Awesome protein/calorie ratio, excellent taste, easily dissolves, easy on the stomach, can't go wrong with this product.
  • Protein powders were found to have heavy metals and lots of other garbage in them (arsenic, cadmium, mercury, and lead, and toxins like bisphenol A (BPA).
Optimum Nutrition Gold Standard 100% Whey Protein Powder, Double Rich Chocolate, 5 Pound
  • This whey contains little else in terms of sugar or carbohydrates so you know there are no fillers.
  • This protein, along with physical activity, will help to stave off muscle loss. Their article made good sense, so I am following their advice: eat lightly and eat protein along with enough fiber.
  • This product is 100% whey from isolates so if you're trying to hit a protein goal while keeping your daily caloric intake down, this is for you.
  • It has worked wonderfully so far allowing me to put on some mass without gaining the fat of other protein supplements. I just ordered another batch and I am a proud user of ON Whey!!
  • If anyone has recommendations on a good protein shake that will give loads of energy for pre-workout let me know.

What customers say about "Features"
Ultimate Nutrition Prostar 100% Whey Protein Powder - Low Carb
  • I mix it in with my oatmeal every morning and has no problems with clumps or a chalky taste.
  • It mixes quite well - using a shaker cup, I rarely had clumps of any sort. My usual shake include 2tsp of fiber powder and 1tsp of creatine, and with these the shake comes out about right after about 5 minutes.
  • The product itself is very good. Great taste and mixes well into my protein shake every morning.
  • Great product but beware if you are allergic to milk. Since I am, I ended up giving them away
  • It tastes like soapy vanilla with some cookie powder. I tried making it with both water (cold and room temperature), and with milk. I even tried adding a banana or peanut butter.
Optimum Nutrition Gold Standard 100% Whey Protein Powder, Double Rich Chocolate, 5 Pound
  • Taste is good, not with water but fat free milk
  • 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).
  • In milk it's just about as good as a chocolate milkshake. I have to resist the urge to drink more just for the enjoyment. In water it's not quite that good but still very tasty.
  • Mixes really well and quickly with anything including a stick.
  • Everything in the box was in perfect condition except for the gold standard so that means they put it there all damaged in the first place.
