Manufacturer Says:
Optimum 100% Whey Protein won the Supplement Of The Year and Protein Powder Of The Year award for 2005, 2006 and 2007! Since the very beginning, Optimum Nutrition has raised the standard by which all other whey protein supplements are judged. Now we’re raising the bar again with the 3rd generation of ON 100% Whey Protein: ON 100% Whey Gold Standard.
Like its predecessors, this canister of ON 100% Whey Gold Standard contains Optimum Nutrition’s exclusive, proprietary blend of…
- Microfiltered Whey Protein Isolates
- Ion-Exchange Whey Protein Isolates
- Ultrafiltered Whey Protein Concentrate
- HydroWhey Hydrolyzed Whey Peptides
To give you more of what you want (pure, unadulterated whey protein) with less of what you don’t (fat, saturated fat, cholesterol, lactose, and other carbohydrates) with every serving. This whey protein supplement is no exception. In fact, ON 100% Whey Gold Standard is better than ever! Here’s why:
- ON 100% Whey Gold Standard provides more whey protein isolates (WPI) - the purest and most expensive source of whey protein available.
- Higher protein percentage. ON’s 100% Whey Gold Standard has always been a leader in this respect. Now with 24 grams of protein in just slightly over one-ounce serving, it’s nearly 79% protein by weight!
- We’ve included more HydroWhey strategically hydrolyzed, low molecular weight whey peptides to make ON’s 100% Whey Gold Standard even faster acting!
- ON’s 100% Whey Gold Standard now contains lactase and Aminogen digestive enzymes to further enhance absorption and make this product even more friendly to lactose intolerant individuals.
- ON’s 100% Whey Gold Standard is instantized to mix easily and completely with just a few twirls of a spoon.
- Every serving supplies even more low, moderate, and high molecular weight, biologically active whey protein microfractions including Alpha-lactalbumin, Glycomacropeptides, Beta-lactoglobulin, Immunoglobulin G (IgG), Lactoferrin, lactoperoxidase, and various growth factors.
- Over 4 grams of glutamine and glutamine precursors as well as 5 grams of BCAAs (leucine, isoleucine, and valine) in each scoop!



Good all round protein, been using it since I started lifting in 2002. Best flavors are:
# Extreme Milk Chocolate
# French Vanilla Creme
Tastes good mixed with low fat milk too.
ON whey is THE best protein product on the market. I have been using it for 4 years now with excellent results. It tastes good, is good on price, and has the right ingredients needed in a whey protein product. A+
Definitely one of the top 5 protein products. Have a good macronutrient profile for the price. Choc flavor is a bit rich, go for strawberry!!!
I’ve been using 100% Whey Protein for weight loss for 1 year. In that time I’ve lost 60 lbs. I’m 44 years old 6′2″ and I weighed 280 lbs and now weight 220 lbs. I’ve had my weight stable at around 220 for 5 months. I got off blood pressure medication, stopped taking pain medications for my back and I feel great. Now I eat what I want but smaller portions and include 2 protein drinks per day. If I see my weight creeping up I eat one good meal a day stay away from any snacks and have 3 or 4 of the protein drinks. It works like a charm for me. I think this stuff may have saved my life or at least make the rest of my life much better.
I like ON, they’re a no BS brand (unlike some others *cough* muscletech *cough*). The whey protein tastes awesome, rocky road is the best flavor by far. Mix it in with some simple carbs after your workout and it tastes even better. I tried about 6 other protein powders before this, and I’ve never looked back…2 years I’ve been on it, great results.
Great protein powder, mixes well - great for fruit smoothies!!
