Jay's Expert Tip

High quality mass gainer and best to be used if you struggle to get enough calories in your diet. Good tasting and a very popular product. Take for a week to assess your results. If you're not gaining weight, increase the number of serves each day until you move into a calorie overload.

Details

Optimum Nutrition is arguably the biggest name in the field when it comes to supplements, and Serious Mass is just another stellar addition to their fantastic line-up of products.

Serious Mass is designed to do exactly what it says: put some serious muscle mass onto your physique. This special blend is loaded with 1,250 calories, which is the most important benefit of this product.

In order to gain weight, you must eat more calories than you burn during the course of the day. To do that repeatedly with healthy foods is a task that is sometimes difficult for a lot of individuals who are trying to put mass on their frame.

However, Serious Mass gets you huge in a hurry, as the calorie bomb that is in this weight gainer is designed to make it much easier to reach your caloric needs from a simple serving of this mass gainer.

ON Serious Mass also contains 250g of carbs, which is the second most important macronutrient for building muscle, right behind protein. Carbohydrates are used as the main fuel source for your muscles, and when you are trying to build mass onto your physique, carbs can play a significant role in helping you achieve that goal.

With over 250g of carbs in each serving, this product delivers exactly what you need in order to fuel your muscles up, and keep them at optimal performance.

Each serving also contains 50g of protein, which is the #1 most important factor when it comes to building muscle. Protein is known as the “building blocks” for muscle growth, and is the most commonly researched macronutrient when it comes to its effects on gaining mass.

The results don’t lie: you need to get an adequate amount of protein in your diet in order to see the results you want. And with 50g of protein per serving, this means that you are already well on your way to reaching your daily goal.

Creatine, the most heavily researched supplement in the game, is also in this product. Creatine has been proven to have beneficial effects on performance and weight gain. When you combine that with the fact that this product also contains 250g of carbs, 50g of protein, and 1,250 calories per serving, then you are ingesting a monster of a weight gainer.

Along with the effects of Creatine, ON Serious Mass also is enhanced with Glutamine & Glutamic Acid. These both help in the formation of protein in the body, which is used to help build muscle.

The benefits don’t stop there either! Serious Mass contains no added sugars, and is also loaded with 25 vitamins and essential minerals, which helps you to enhance your healthy diet. On top if this, it also contains whey concentrate, whey isolates, and casein & egg proteins. This fills your body with a variety of effective proteins in a single blend, priming your body for optimal muscle growth.

Buy Optimum Nutrition’s Serious Mass today to leave your old self behind, and pack on the pounds of muscle you have been working hard for.

Great for bulking

By Sasha reviewed on 13/08/2019

This product is great if you’re looking for serious mass gains and want a product that is top quality. Optimum nutrition is one of the best brands - the serious mass is good if you want a calorie filled gainer that helps you put on size. However, if you can afford to spend a bit more ON’s gold standard gainer is the best gainer product available and more versatile for when to take it. Definitely would recommend either for purchase if you’re looking to add size.

The strawberry flavour while nice can be a bit much after a while (also a little grainy). I would recommend ON flavours like cookies and cream, chocolate or vanilla which you never get sick of and are delicious.

First time using a mass, I struggle to put on weight but have started to pack on the kgs in a very short period of time. Highly recommend for anyone else who struggles to gain weight and lives a busy and active lifestyle, and also finds it hard to find time to get full meals in during the day. Only negative is that it will become an expensive hobby as I’ve gone through the 5kg bag very quickly. Great product though ????????

Does what it says increases calorie intake, not the best tasting chocolate flavour in my opinion but taste is subjective. Good product

Great tasting Whey

By Richard reviewed on 20/04/2019

I have purchased this product twice now.
Tastes great, like a chocolate thickshake.
The powder is fine so best to use a large shaker to avoid the whey sticking to the bottom.

Does what it claims'

By Andy reviewed on 1/04/2019

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Well as the title says it definitely does what is says in regards to an amplified calorie intake and seriously helps build the mass in coming time as would be expected.
Very light to drink and the same to digest, doesn't give you a heavy stomach feel and digests pretty damn quick!
In my case, metabolism throughout the day definitely increased also.
Highly recommended for an intense bulk for the advanced bodybuilder.
With a proper set diet & training this makes calorie overload a breeze.
Good on flavor which puts this product in the best of both worlds.
Thumbs up from me.

I've used many a protein powder and this is the one I'll be coming back for. Cycling between convenient store powders and generic ones from the local supp shop, I'd gladly pay the extra shipping price (my area is always a struggle for packages) for this. Will be coming back! Cheers.

It does what it says & I am enjoying the accurate calories I required for my workout session .
Excellent job with this brilliant product!
