Do you have that toothpick physique, small as a twig, and have wanted to grow into a beast? Look no further than my Optimum Nutrition Serious Mass Review! As a mass gainer, you can expect to put on some size from drinking this. However, not all mass gainers were created equal, some being better than others for specific reasons. For some, these supplements can be the solution they’ve been looking for. While others may get even more frustrated from their lack of good results. After reading this review, you’ll know for sure if buying ON’s Serious Mass is a good investment.

Mass Gainer vs. Protein Powder

In case you don’t know, a mass gainer isn’t just your ordinary protein shake every lifter has in their arsenal. These supplements are a different beast when it comes to dietary supplements, similar to protein powders, but different. Here are a couple of differences between regular protein powders and mass gainers.

Calorie Count 

Probably the easiest difference to tell between a protein powder and a mass gainer is the total amount of calories in a scoop. The calories in a mass gainer are going to exceed that of protein powder and by a lot. There’s a purpose to this, to gain size. You will never, and I repeat, never, increase size if you burn more calories than you consume. It’s just not possible scientifically, you need more calories to fill your body’s needs to grow. Have a look at these two dietary supplement’s nutrition labels, spot the difference if you can. Optimum Nutrition Serious Mass Review - Time To Bulk

On the left, we have Optimum Nutrition’s Serious Mass. On the right, we have my personal favorite protein powder, Bodybuilding.com’s Signature Whey Protein. If you’d like to know why it’s my favorite, click here for my review on it. But, back to this. Notice the drastic difference in calories between the scoops. The point of the mass gainer is to try and put you in a caloric surplus, state of which you eat more calories than you consume.

For the average person, they should be getting around 2,000 calories a day, more or less. That number varies from person to person, but that’s a solid average. Two scoops of this protein easily knock out more than half your caloric needs. Add this on top of breakfast, lunch, and dinner, you’ll be consuming a lot of calories, which is the goal.

Vitamins and Minerals

Let’s have a look at the two dietary supplement labels again, and see if you can notice anything regarding the length of the two. Take a nice hard look at the two, it may not be evident for everyone.

Once again, we have Serious Mass on the left and Bodybuilding.com’s Signature Whey on the right-hand side. The whey protein has about 4 vitamins and minerals in total, which is not bad for a protein powder. The daily values aren’t a high percentage either, but they’re still there for the ride. The mass gainer towers over the protein powder in this aspect, I counted a total of 25 vitamins and minerals. Looking at the daily values, you’ll complete all your needed vitamin and mineral intake with just one serving.


Another big, no pun intended, the difference between the two supplements is the size they both come in. Typically, they both come in proper decent sizes that’ll last you quite a while. But with a mass gainer, it’ll last you quite some time, at least that’s the case with Optimum Nutrition’s Serious Mass. The biggest container you can buy from their site is a whopping 12lbs, which is ginormous. That’s about the size of a gallon of paint, some people can’t even carry gallons of paint without using two hands.

Also, you’d think that the heavy container would cost you a fortune. But in reality, it’s not more costly than your average protein powder. The listed amount for the 12-pound behemoth is about $57, coming to about a little less than $4 per serving. There are protein powders that cost more and weigh less, much less. Which is pretty outrageous now that you know a supplement as heavy as can of paint be more affordable.

What Sets Serious Mass Apart?

This wouldn’t be an Optimum Nutrition Serious Mass review if I didn’t talk about its specialties. As if you weren’t already convinced how much butt Serious Mass kicks, it’s got more to show off. I already touched on the vitamins and minerals, but the macronutrients are something I need to discuss. Have another quick look at the nutritional label, and observe the glory of the nutrients packed in this supplement.

I already talked about the calories, and how much they got in store. There are not too many grams of fat in a serving, which isn’t a bad thing. Notice how there’s saturated fat and no trans fat, that’s a good thing. Trans fats are the fats that clog your arteries located in many processed foods. Excess artery blockage can lead to cardiovascular problems like heart disease, high blood pressure, and in worse cases, heart attack. In short, stay away from trans fats as frequently as possible.

The carbohydrates in this mass gainer are through the roof, a total of 254 grams in a serving. Many people think that when building muscle, all you need is protein in your diet to start feeding your muscles. In reality, you need all your macronutrients, especially your carbohydrates, to really build your muscles. You’ve got both your carbs and your proteins covered in this mass gainer, packing 50g of protein in a serving. Combine this powder with a balanced diet, you’re on your way to achieving that bodybuilder physique you’ve always wanted.

Mouthwatering Taste

Anyone out there who has ever tried a supplement by Optimum Nutrition, you know that their flavoring does disappoint. Adequate when it comes to taste is not in their dictionary. The flavor that always has me craving some more is their chocolate, man oh man is their chocolate something to behold of. In general, I always go for the chocolate flavor on protein powder, but this one stands apart from the rest. Although not my favorite, it’s still one to taste in your supplement drinking lifetime.

If chocolate isn’t your cup of tea, that’s not a problem. Optimum Nutrition has got plenty of other flavors you’re just bound to enjoy. For example, they got their delicious strawberry, vanilla, and even peanut butter. The only taste I can’t really vouch for is the banana, mainly because I don’t really like bananas. It’s not that I despise the yellow fruit, it’s just isn’t my preferred fruit, there are plenty better out there. But if you love banana, that’s the flavor for you! Please don’t hate me, banana lovers, it’s just my opinion.


In conclusion of this Optimum Nutrition Serious Mass review, I can say that ON has once again manufactured another great supplement. It’s well known in the industry that Optimum Nutrition is a respected company that delivers top-notch supplements. I expected nothing less from them to create such a great supplement.
