About the Product
Impact Whey Protein is a fast absorbing source of protein that is a by-product formed during the manufacturing of milk and cheese. Each serving of Impact Whey Protein contains over 80% of undenatured protein, providing a range of both essential and non-essential amino acids which are important for recovery and stimulating muscle growth.
OPTIMUM NUTRITION'S GOLD STANDARD 100% Whey uses pure Whey Protein Isolates as the primary ingredient. Combined with ultra-filtered whey protein concentrate, each serving provides 24 grams of all-whey protein and 5.5 grams of naturally occurring Branched Chain Amino Acids (BCAAs) which are prized by athletes for their muscle building qualities.

What customers say about "Key Specs"
Myprotein Impact Whey Protein Chocolate Smooth
  • I've had a couple shakes with this so far and as far as a protein powder goes I do like the flavor pretty well.
  • It's great with milk, but what I like to do is add a little bit of cocoa powder and man this is one of the best wheys.
  • With water it's actually one of the most bearable protein powders out there.
  • Tastes Delicious and well, such a good purchase!
  • The flavor is weak and sort of tastes like a hint of a hint of chocolate.
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"
Myprotein Impact Whey Protein Chocolate Smooth
  • I like the calorie to protein ratio!
  • Great product. Tastes great very low sugar content.
  • This stuff is excellent value when you take into consideration the percentage of actual protein per gram and per serving.
  • I think this stuff is close to 77% protein by weight. For comparison, BSN Syntha-6 is about 53% protein by weight.
  • It's a good price, but that's really just because each serving isn't very large and doesn't contain much protein compared to lots of other protein supps.
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"
Myprotein Impact Whey Protein Chocolate Smooth
  • This product was reviewed by Labdoor, an independent company that tests supplements. This protein was listed as the #1 Protein Supplement.
  • Taste great, easily mixed, and it works.
  • Taste good. Mixes pretty well too!
  • Forget about mixing it with water because that just tastes like when you forget to rinse out a cup after drinking chocolate milk.
  • It’s super bland, watery, and doesn’t mix very well. Lots of clumps.
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.
