Authenticity Tips
VACUUM SEAL
Serious Mass tubs have a cardboard vacuum barrier that helps hold powder in place during shipping. This gloss white protective disk should be stuck to top of the tub.
NECKBAND
In order to conform to the direction of our sustainability policy and goals, we have decided to remove this part of the packaging. Packaging may vary for a certain period of time as this change takes into effect.
FILL SIZE
Due to vacuum packing the tub may appear to be two-thirds full when opened. This is normal as the powder settles and does not impact on or decrease the weight or number of serves listed on the label.
BATCH NUMBER AND DATE
Every Optimum Nutrition product will display a printed Batch Number and Date. The Best Before Date and Batch Codes are located on the side of the tub or the rear of the large bags.
What’s new with Serious Mass?
Not only does Serious Mass have a fresh new look, but it also has added 3 grams of creatine to support your performance.
The label looks different compared to the previous one I got, is it still the same OPTIMUM NUTRITION product?
As you evolve, so do we. The part of our mission is to help active individuals better understand OPTIMUM NUTRITION products. Now choosing the right product for you is easier with more visible product benefits, features and flavours on each tub.
The tub is not full to the brim when opened, why is that?
This is completely normal and is to do with the way the powder is vacuum packed into the tub. The powder settles over time. This does not impact the weight or number of servings listed on the label.
What is the best way to prepare Serious Mass drink?
To get the optimal consistency and prepare your drink in easy and convenient way, we recommend using a blender.
For optimal use, follow serving instructions on pack.
Are the ingredients tested and safe?
All of the ingredients in our products have been approved and considered safe for consumption by the European Food Safety Authority.

Il start by saying I never leave reviews on anything but I absolutely had to write one for this! I read all the reviews before buying and there wasn’t many on the strawberry flavor so I felt I took a risk, I’m so glad I did!! It tastes amazing if your a fan of the strawberry Angel delight pudding then you will love this it tastes exactly the same!! I can’t wait to have my shake everyday because I enjoy it so much, iv tried a few different brands and they always leave a powdery taste in my mouth and a not so nice aftertaste this is nothing like that it’s so yummy!! Please bear in mind I mix mine with milk not water! I definitely recommend I will be buying this on repeat!
The only thing that surprised me was the scoop size it’s huge!!! I imagine I will get through it quite fast but to be honest with the amount of calories and protein and the flavor I don’t care! It’s worth it happy customer 🙂
I originally tried it with water and seemed to have over diluted it and it didn’t taste the best because obviously it was water, so I would recommend it with milk despite the creatine content especially for bulking. As for the portion size, it doesn’t seem as though you’re getting a lot for your money especially when you think about the size of the tub and the price you’re paying as you only get 8 full servings, but the tub is full and can probably last you a while on a balanced intake. This also makes it cheaper when comparing to some other protein drinks.
Is good, flavour is nice, get a hefty amount of powder but I just don’t really like it as a drink with water. With milk, its okay but I need a better way…maybe with Yoghurt and granola
I had ordered the same but in vanilla, it was absolutely revolting and it smelled and tasted like a bunch of chemicals I really tried to convince myself it wasn’t that bad but no matter what i mixed it with it was terrible hence why i switched to the strawberry and it tastes amazing, it tastes just like the strawberry nesquick or like a strawberry milkshake. It doesn’t smell chemically at all despite the many reviews where it says it does and in my
opinion it’s the best flavour out of all of them and i think it’s a lot easier to drink if you’re not too keen on using enhancing products like serious mass since you’ll actually enjoy the taste and personally it motivated me to drink it more often and stick to it.
