What customers say about "Key Specs"
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.
BSN SYNTHA-6 Whey Protein Powder
  • Taste was pretty good of the Chocolate Milkshake. The container looked like it was never full but the label indicated it is filled by weight, not volume.
  • Taste much better than i thought it would...not to sweet or overpowering vanilla flavoring...
  • Tastes excellent, nice creamy flavour without the artificial taste that many other protein shakes have.
  • Decent flavour, mixes well, good price.
  • Not the best flavour or brand. Good for the price.

What customers say about "Amount Per Serving"
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.
BSN SYNTHA-6 Whey Protein Powder
  • I’m an athletic/average college student. I’ve tried many protein brands, and this the best tasting and most nutritious one I’ve ever had.
  • It comes in a bag with 97 servings, that’s a lot of servings.
  • For somebody having 1 serving it's not bad, but anybody serious should have more then 1 serving (Usually around 1 gram of protein for 1 pound of body weight).
  • The cholesterol level in a serving is the only negative thing that seems to be a little high, but I imagine a healthy adult who's not taking massive amount of this protein daily would be just fine.
  • Good luck to all of your on your quest in finding a good quality and affordable protein powder. For us, this wasn’t it.

What customers say about "Features"
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.
BSN SYNTHA-6 Whey Protein Powder
  • The protein tastes very good! A little bit sweet. It mixes great in both water and milk with no clumps.
  • Its formula features multiple quality proteins resulting in a nutritious and multi-functional protein supplement that ensures an athlete's muscles a quality supply of protein building blocks.
  • Along with the premium features it affords, so too does it come with a premium price.
  • The product has many features included however I supplement with other products but overall good.
  • I had just opened mine when the closing feature failed. I now have to transfer all of the product into my own container.
