Why does Optimum Nutrition have different sizes for flavours?

Each serving must contain 24 grams of protein.

Serving size varies on the amount of flavouring and colouring needed.

ON tries to fill the tubs to the nearest 900 grams.

For example, if an extra serving of Cookies and Cream was added, it would increase the servings to 29 but the tub weight would then become 928 grams (896 grams + 32 grams).

This would then increase logistics costs.

Simple – Exercise – Drink ON – Muscles grow!
Review by Ice (28 February 2017)
I have first tried the 900g because it's so expensive (cookies & cream very nice). I am going to order the 2.2kg now - this whey works amazing. I recover quickly. I have been using whey now for 5 years and I can now actually see my muscles grow and getting definition quickly for the 1st time.
However, I will see how long this one lasts and whether I can/will afford going on with this.
If not, I will definitely alternate with ON every 2nd or 3rd month. No other whey works like this one.
it is my first time using this and it is perfect and very tastey.

Review by Ayrt (25 October 2016)
By far, the best protein that I've ever used. I've been on a strict meal plan training 6 days a week and taking my shake immediately after my session. GAINS!!! Being accused of using other stuff at the gym. That's how much of a difference using quality protein makes.
Simply the best
Review by Jay (18 August 2016)
I've been drinking protein shakes for about 15 years now, from various suppliers, so trust me when I say this protein shake is the best - by MILES.

Why? Firstly, I've always hated the taste of protein shakes, but somehow ON figured out how to make them taste like actual milkshakes (even if you mix it with water, like I do). Just make sure you mix it properly (not too much liquid). And that is my other favourite thing about this product - I literally mix 1 scoop in about 150 ml of water! WITH A TEASPOON... and it's done! No more blenders and shakers filled with 500 ml of thick, disgusting-tasting gunk that makes you feel full and bloated...

But most of all, the results are obvious. (Assuming you know what you're doing in the gym). The quality of the muscle I gained over 6-8 weeks was unmatched by any other supplements I've taken. And it wasn't just me who noticed it, two guys actually came up to me in the gym and asked me how I got the definition in my muscles. My answer: "dumbbells, 10-12 reps, and ON Whey".

I don't care about the price. I can never go back to another protein shake.
Great product
Review by Cohen R (9 February 2016)
Been using it for 3 months now and I can see noticeable differences with regards to lean muscle. By far, the best whey on the market. Been using cookies and cream which smells and tastes devine!
Great... But pricy
Review by Ciffsome (19 November 2015)
Best stuff on the market, but quite expensive
Well I tried eveything. And only this works!
Review by Will (26 August 2015)
I have tried so many protein supplements and I always have the same reaction! POOP! But not this! This is the only Whey I can consume with no side effects. I would highly recommend this!

P.S. I am not lactose intolerant but can't stomach Whey Protein
Fantastic but expensive
Review by JP (13 August 2015)
I become depressed when it's finished because of the cost of replacing it, but I have seen the difference in quality compared to peers based on the results I experienced. Just expected a little more on the taste side, especially for the price you pay.
best prorein iv used
Review by kyle (8 October 2014)
On 100% whey is a very good protein powder, it works well with my body. It dissolves very very easy, doesn't have the best taste IMO. On 100% Whey goes perfect with on pure creatine!
