Serious Mass is a hardcore weight gainer which is literally bursting at the seams with calories. It is designed so it can be taken a pre and post workout shake. Feel free to take this supplement twice a day if you’re not meeting your daily nutrition requirements through real foods.

The protein formula comprises a mix of whey protein concentrate, egg albumen, calcium caseinate, and sweet dairy whey. This makes for a moderate to slow release of protein throughout the day, meaning your body will be constantly feasting on the good stuff.

Benefits of Using Serious Mass

Increased Muscle Strength: Mass gainers aren’t called that for no reason. An effective mass gainer like ON’s Serious Mass can help you gain serious strength in a short period of time. You will notice the difference within a couple of months.

Meeting High-Calorie Requirements: If you have a big muscle gaining goal or if you’re a hard gainer, muscle gainers can be a life saver for you. These supplements pack a big amount of calories in a small and easy-to-take serving.

Meets Your Creatine and Other Requirements: Serious Mass comes packed with creatine, vitamins, and minerals. You don’t need to buy other supplements to meet your daily requirements, eliminating the need to buy these products separately. This can save you a lot of time and money.

Increased Fat Burning: Many muscle supplements contain branched-chain amino acids. Amino acids are the building blocks of protein and are used to build muscle. Serious mass comes with a particular type of dietary fat which helps to keep you leaner while you go about the muscle-building process.

Increased Muscle Mass: This is what you’re taking your Serious Mass mass gainer supplement for. This supplement will help you meet all your daily nutrition requirements and will provide the stimulus for muscle growth.

Side Effects of Mass Gainers

While there are no documented side effects of using ON Serious Mass, here are a few side effects you can have if you’re not using the right mass gaining supplement:

Kidney Problems: Kidney ailments are predominantly associated with intake of weight gain powder. Although weight gain powder is an indirect cause of kidney stones, it can make body’s hormones susceptible to it.

Digestive Disorders: Some people have an adverse effect to mass gainers. Some types of proteins cause users to feel bloated, or to experience stomach cramps. Some mass gainers cause users to have an excess of gas and to feel discomfort for several hours after ingesting the powder.

Muscle Pulls and Cramps: Sometimes people train too exhaustively with unrealistic supposition. The assumed approach may result in a lack of sufficient fluid supply that can cause muscle pulls/cramps.

Undesirable Fat Gain: Because these powders are meant to increase your caloric intake to help with workouts and healthy muscle gain, some people don’t realize that they need to couple powder intake with strict workouts or otherwise they can end up gaining unwanted fat.

Liver Problems: Mass gainers are also high in protein quantities. Like any diet high in protein, users risk damaging their livers by not following safety rules. Many users don’t drink enough water and begin to use the protein powders as a supplement to other, more well-balanced meals.

Price and Where To Buy



Optimum Nutrition’s Serious Mass is one of the best supplements for weight and muscle gaining because it provides a large dose of the nutrients from protein, carbs, and fats to micronutrients like vitamins and minerals needed for mass gains.

Getting a mass gainer can be a critical decision as a substandard product can push you in the wrong direction. You need to be selective of all the ingredients present in the supplement and how they would help you reach your goals. If you’re looking for a product which delivers, rest assured, you can’t go wrong with Serious Mass.
