Optimum Nutrition 100% Whey Gold Standard provides whey protein isolates [WPI) - the purest and most expensive source of whey protein available. It now also has a higher protein percentage. ON's 100% Whey Gold Standard has always been a leader in this respect, ad Fitness Ireland are one of Irelands largest retailers of Gold Standard. Now with 24 grams of protein in just slightly over a one-ounce serving, it's nearly 79% protein by weight!

Optimum Nutrition have included more HydroWhey strategically hydrolyzed, low molecular weight whey peptides to make ON's 100% Whey Gold Standard even faster acting!

ON 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 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!

ON - 100% CASEIN [2LBS]

Gold Standard 100% Casein from Optimum Nutrition is the World’s No. 1 and the industry’s first all-micellar Casein.

Recommended for use in the evening, each great tasting Gold Standard 100% Casein shake contains 24g of the purest protein, 3g of carbohydrates, but just 0.5g of fat and no sugar. It’s also instantised to mix up easily, every time.


Used together, Gold Standard 100% Whey and Gold Standard 100% Casein deliver 24 hour muscle support.

It tastes delicious, is low in sugar and fat, and contains approx. 110 calories per serving.


Casein is best taken at night, as this is when the majority of muscle rebuilding takes place. Simply add one rounded scoop to 10-12 oz [300-360ml) of water, milk or your favourite drink in a Fitness Ireland shaker half an hour before bed.
