Posted on |Fitness, Food|| 0


With so many different brands out there competing for the title of the best mass gainer, anyone can get caught in the dilemma of choosing the most appropriate one that suits their requirements. In this post, we will review a mass gainer well known within the fitness community. Serious Mass By Optimum Nutrition has been around for quite some time now and is known for yielding the desired results if you really dedicate yourself to it. Optimum Nutrition itself has been dominating the industry for a long time starting off in 1986. Some famous products are Whey Protein, Creatine, and Glutamine. Their reputation is backed up by excellent customer reviews who are satisfied with the high-quality products.

The Serious Mass is strictly for people looking for a caloric surplus and looking for a weight gainer. Combined with a good diet containing all the essential nutrients, you should start seeing results in a few months. With that said let’s get on with it and proceed to the nutrition facts review.

Serious Mass By Optimum Nutrition Nutrition Facts

It contains a total of 1250 calories with everything you can possibly imagine that would help muscle growth. Therefore it isn’t just a supplement, but a scoopful of essential Amino Acids, Vitamins, Fats, and much more. Oh yeah! I almost forgot to mention that this is strictly for hard gainers who are willing to undergo what it takes if you want to put the mass on. The nutrition facts will confirm it.

Fats and Cholesterol

Contains 4.5g of total fat and 2.5g of saturated fat per serving. Fat is not a well-received source of growth by anyone because it rings the alarm of heart diseases and cholesterol. However saturated fats are essential when gaining muscle and are found in lean pork, beef, lamb, and even cheese and eggs. Another important fact is that saturated fat has a direct link with testosterone production and so does cholesterol. Elevated testosterone results in faster muscle growth and reduced recovery time post-workout. Yes, we have to limit the fat intake. But that is mainly for the static people who aren’t active. If you are an athletic person, you must consider fat intake(healthy fats) and stick to your routine to witness optimum results.

There is 110 mg of cholesterol in Serious Mass. Here cholesterol is in reference to dietary cholesterol which has no relation with blood cholesterol. Dietary cholesterol consumption yields an increase in muscle growth, athletic performance, and strength building. A study among a group of individuals engaged in weight training showed that they gained more muscle mass when consuming more cholesterol. There are also studies that prove the higher rate of protein synthesis in humans who consume more cholesterol as opposed to those who don’t. Protein synthesis is a direct measurement of muscle growth. Also the link we mentioned earlier with testosterone production that aids muscle growth. However make no mistake, you must consume all of these while giving it your best in the gym.


Serious Mass contains 252g of Carbs per serving. Healthy carbs are the fuel for getting big along with protein. How so? In short, they provide the fuel for your body to output in the gym. Of course, the amount varies with each individual according to age, fitness level, workout intensity, etc. However, it doesn’t change the fact that Carbohydrates are an absolute must if you want to put muscle mass on or even lean out for that matter. You’ve probably heard of muscle glycogen. It is a form of glucose that is stored as energy in the liver and skeletal muscles. Well, Carbs replenish glycogen stored in your muscles and liver and reduces fatigue during strength training.

In the case of Serious Mass, 4g of dietary fiber is present in the complex carbohydrate. Some examples of complex carbs are whole wheat, brown rice, oatmeal, whole barley, and quinoa. This is the form of carbs you need to intake to put muscle on. You should avoid simple carbs like sugars because they render empty calories and serve no purpose in building muscle. The complex carbohydrates take quite some time to digest and be absorbed into the muscle.


The building blocks of muscle. When the muscle is torn in the gym with all the exercises, protein helps them grow bigger when they are repaired during recovery. Serious Mass contains 50 grams of protein per serving. This and the protein combined from the food that you intake should help recover the torn muscle and keep them growing. See to it that you consume enough chicken breasts, broccoli, and spinach.


Vitamins A, C, D, E, B6, B12, Calcium, Biotin, and much more contribute to muscle growth at the cellular level. Cellular production and tissue repair depend on a variety of vitamins and minerals. For example, Vitamin D is the most important vitamin for testosterone production, Vitamin C aids in collagen formation and an antioxidant. Vitamin E is another powerful antioxidant that helps eliminate free radicals. These are also widely used in pre-workouts because of their antioxidant properties.

Apart from the Fats, Carbs, Proteins, and vitamins, Serious Mass also comprises 3g of Creatine, 500mg of L-Glutamine, and 250 mg of Inositol.

Serious Mass By Optimum Nutrition Review

Now that we are aware of what is contained in the 1250 calories per serving, let’s review the value it delivers for someone who wants to put on healthy muscle mass.


We mentioned the reputation of Optimum Nutrition earlier. It has been trusted to provide the highest quality specializing in post-workout recovery for over 30 years and in 90+countries. After verified and trusted supplier selection, each ingredient is tested to assure exceptional and optimal purity, potency, and composition. If you ask any fitness enthusiast or conduct a little research on best mass gainer yourself, you are bound to see Serious Mass on the top. The number of carbohydrates, Multivitamins, and minerals, Proteins plus fats are in perfect sync for anyone aiming for weight gain. Also, the integration of Creatine and Glutamine enhances the value furthermore since you can break down scoops and even have it as a pre-workout.


The mixability is a bit of a drawback here if you are using 2 scoops at once. The issue is the inconvenience when mixing it with fluids such as water or milk in a shaker. You are most likely to end up with unmixed lumps as opposed to Whey protein. Therefore it is best to mix in a blender with either milk for more calories, or merely adding water. Also if you are super serious about packing muscle, you can add some peanut butter, banana, or even some oatmeal. These will further increase the calories and accelerate recovery time. Since this is a weight gainer the mixability is bound to have some issues. Therefore make sure to get the blender first.


Needless to say Chocolate is everyone’s favorite pick. Still, there are a few more choices that you might like;

  • Strawberry
  • Vanilla
  • Chocolate Peanut Butter
  • Banana
  • Cookies & Cream

Personally, I’ve tried Chocolate and Strawberry flavors of Whey protein by Optimum Nutrition. Again, I too enjoyed the Chocolate flavor best. I’m guessing the same applies to here as well. However, some users have positively reviewed the Peanut Butter Chocolate flavor. The important thing to keep in mind is that whichever flavor you use, combining it with more calories results in a heavy meal. This means if you are planning on using milk as a base, you will feel quite full given that you are consuming an almost complete meal. You have to plan your diet accordingly.


At this point, it’s obvious that Serious Mass is a good price to value an efficient product. Although there aren’t many servings as in Whey protein, the fact remains that it is a great product overall that has been delivering optimal results for its users for a long time. Also, you have to keep in mind that a protein powder is solely focused on protein intake while the mass gainer qualifies as a complete, nutrient-dense meal. Therefore the reduction in servings per tub is agreeable. The fact that makes Serious Mass stand from its competitors such as Mutant Mass is the ingredient combination.

How To Use Serious Mass Gainer?

As we mentioned earlier, you can have it between meals, after the gym, and before bed. However, you can further customize according to your body chemistry, caloric requirements, etc. A few typical examples are as follows.

Obviously, you need to have it post-workout to refuel your muscles and jump-start them. After the body is depleted of the nutrients, it is very beneficial to have something as good as Serious Mass with over 1250 calories per serving. You can also consume a scoop first thing in the morning with your breakfast. At that time too your body is hungry for nutrients. Having a scoop pre-workout and a scoop post-workout is another method that you can adopt. Either way, make sure to consume 2 scoops per day to ensure maximum results.

Serious Mass Side Effects

We cannot stress enough how hard you should be pushing yourself to the limits at the gym if you are using Serious Mass. Because the moment you start slacking off, the more fat you are going to gain instead of muscle mass. And also it should be noted that every supplement reacts differently according to the body chemistry of different users. A classic example is the pre-workouts. To name a few basic side effects of Serious Mass, you can expect Diarrhea, Nausea, Muscle Cramps, and of course, Excessive weight gain if you haven’t been serious about Serious Mass.

Therefore the usual healthy advice is to consult a trained professional who is aware of your body chemistry first and then start with small doses. Then as your strength, endurance, and fitness progress, you can consider increasing the amount.


Serious Mass By Optimum Nutrition is undoubtedly a great weight gainer of our time if utilized effectively. However, as we mention in each of our supplement reviews, no supplement can replace the value that nutritionally dense whole foods deliver. In fact, as a beginner, if you stick to a strict diet plan keeping count of your macros, you are bound to see a change in a few months. Controversially it won’t be the same if you solely rely on supplements. Serious Mass will only be of any use if you stick to your diet and the high-intensity workout and of course the rest(sleep). Yes, it is expensive, but it delivers immense value for what it’s worth. Hence the popularity within the fitness community.
