Why Optimum Nutrition Serious Mass Is Necessary
When I was struggling to gain weight and build muscle, I realized that just eating regular meals wasn’t enough to meet my calorie needs. That’s when I found Optimum Nutrition Serious Mass. For me, it’s necessary because it provides a convenient, high-calorie shake packed with the nutrients my body needs to grow. I can easily consume over 1,250 calories in one serving, which would be tough to get from whole foods alone, especially on a busy schedule.
Another reason I rely on Serious Mass is the balanced blend of proteins, carbs, and vitamins that support my recovery and muscle growth. It’s not just about calories; it’s about quality nutrition that fuels my workouts and helps me gain lean muscle without feeling weighed down.

My Buying Guides on Optimum Nutrition Serious Mass
When I decided to gain weight and build muscle, I turned to Optimum Nutrition Serious Mass. Here’s what I learned during my buying journey that might help you too.
Why I Chose Optimum Nutrition Serious Mass
I needed a high-calorie supplement to support my weight gain goals. Serious Mass offers 1,250 calories per serving, which was perfect for me because it provided the extra energy I couldn’t get from regular meals alone.
Key Nutritional Benefits I Looked For
- Calories and Carbs: Each serving packs a hefty 252 grams of carbs, giving me the fuel to power through workouts and recovery.
- Protein Content: With 50 grams of protein per serving, it helped me build muscle effectively.
- Vitamins and Minerals: I appreciated that it includes essential vitamins and minerals, helping me cover my nutritional bases.
- Added Creatine and Glutamine: These extras boosted my performance and recovery.
Flavors and Taste Considerations
I found Serious Mass comes in several flavors like chocolate, vanilla, and strawberry. I personally went with chocolate because it blends well and tastes great when mixed with milk or water. If you have a sensitive palate, I recommend starting with a smaller serving to test the taste.
Mixing and Convenience
Serious Mass is a thick shake, so I used a blender for the best consistency. It dissolves better in milk than water, making it creamier and more enjoyable for me.
Serving Size and Usage Tips
One serving is quite large (about 2 heaping scoops), so I often split it into two smaller shakes throughout the day to avoid feeling too full. I usually took it post-workout and between meals.
Price and Value for Money
It’s not the cheapest mass gainer on the market, but considering the quality and calorie count, I felt it was worth the investment for my goals.
Who Should Consider Buying Serious Mass?
If you struggle to eat enough calories or need to gain weight fast, this supplement can be a great help. However, if you’re sensitive to high sugar or lactose, you might want to consider alternatives.
Final Thoughts from My Experience
Optimum Nutrition Serious Mass gave me the calorie boost and nutrition I needed to gain weight steadily. With the right approach, it can be a powerful tool in your muscle-building journey. Just remember to combine it with a good workout routine and balanced diet.
I hope my insights help you make an informed decision!
