When should I take Serious Mass Weight Gainer for best results?

Serious Mass is designed to be consumed post-workout and/or between meals to add serious calories, protein, and carbohydrates to a balanced diet. It is specifically designed for building muscle mass. According to the International Society of Sports Nutrition, consuming protein any time up to two hours post-workout is ideal.

For gaining weight, you can drink this mass gainer supplement between meals, making this a convenient way to get extra calories throughout your day.

If you prefer to add your serious mass protein shake to your evening routine, you can have this before going to bed. Drink 1/2-1 serving of Serious Mass about 45-60 minutes before bed to provide those much-needed nutrients to recovering muscles throughout the night.

Directions for Use:

Serious Mass can be used to add calories, carbohydrates and protein to your diet. New users should start with one scoop (or half a serving) for the first week, moving up to a whole serve per day as their bodies get accustomed to the product.

How to prepare Serious Mass Gainer & Sports Supplement

Mix 2 scoops of Optimum Nutrition Serious Mass in 24 fluid ounces (710mL) of cold water, milk, or beverage of choice. We recommend using a blender or Nutri-bullet to make the shake smooth and creamy. You can add additional flavours such as nuts, peanut butter, fruits or other calorie-heavy foods.

Is it good for skinny guys trying to gain mass?

Optimum Nutrition Serious Mass Gainer provides a uniques blend of protein, fat, carbohydrates and vitamins and minerals to help you achieve your goals. This mass gainer gets you 50 grams of high-quality protein, 4.5 grams of fat, 252-254 grams of carbs, and an impressive 1,250 calories per serving. So it is excellent for skinny guys.

Will it make me gain muscle?

ON’s Serious Mass supports muscle building in conjunction with your weight-lifting and workout routine. Gain significant size by using the ultimate in weight gain formulas. With 1,250 calories per serving, including 50 grams of protein, your body will not only increase in mass but your muscular growth and maintenance are supported too.

Is Serious Mass Gainer healthy?

For people who struggle to eat enough to gain weight, mass gainer supplements are an effective way to increase your calorie intake. Mass gainers differ from protein supplements in their formula by containing protein, carbs and amino acids. So you are getting the benefits of the rich proteins and a complete supplement to support your weight gain goals.

Mass Gainer Flavours

At the Supplement Stop we have the following flavours available:

Chocolate – This delicious flavour is the perfect post-workout treat. It is a cost-effective way to increase your calories and gain weight while supporting your muscular growth. Consider mixing your chocolate with peanut butter, choc-chip cookie dough ice cream or a shot of coffee for that additional caffeine boost. Absolutely delicious!

Vanilla – Taking a generic vanilla flavour, you can really make this mass gainer into anything your tastebuds could imagine. Fresh berries, hazelnuts and cocoa, or try oats, banana and vanilla serious mass as a post-workout breakfast smoothie. This will add some serious calories and see you smashing your daily goals.

Banana – The banana flavour profile is delicious on its own and can be consumed at any time. What we like to add is peanut butter or Nutella, or go all out with caramel ripple ice cream. This is a real winner.
