Description

Struggling to eat enough to gain weight is a real problem for a lot of hardgainers, and it's exactly what Optimum Nutrition's Serious Mass gainer is built to solve. Two scoops delivers 1250 calories, 50g of protein and over 250g of carbohydrates, making it one of the simplest ways to close a calorie gap that food alone isn't covering.

Who actually needs Serious Mass?

Serious Mass isn't for everyone chasing muscle, it's specifically for people who are training hard but still can't gain weight, or who don't have the time or appetite to eat enough through meals alone. If you're already gaining weight steadily on your current diet, a standard protein is likely a better fit than a high-calorie gainer.

What's in each serve

1250 calories per two-scoop serve
50g of protein to support muscle maintenance and growth
250g+ of carbohydrates to fuel training and refill glycogen stores
No added sugars, sweetened instead through the carb blend itself
Creatine monohydrate included for strength, power and size support
20 vitamins and minerals added to round out the nutritional profile

Getting the dose right

Two scoops blended with 700-720ml of cold water or milk is a full serve, an electric blender handles the thickness better than a shaker. If you're new to gainers, start with one scoop (half serve) and build up once your body's used to the extra volume and calories. Works well post-training to kickstart recovery, or between meals on days you're struggling to hit your calorie target.

Building it into your routine

Training harder or more often is common during a bulk, so a High Stim Pre-Workout is worth a look if your current one isn't cutting it for the extra volume. Serious Mass already includes creatine, so there's no need to add more unless you're deliberately after a higher daily dose.

Common questions

Can this replace a meal?

Yes, with 1250 calories and a full macro spread, it works well as a meal replacement on days you're short on time or appetite.

Will it make me gain fat instead of muscle?

Weight gain depends on training and total intake, not just this product, but pairing it with consistent resistance training is how the extra calories and protein get put to good use.

Do I need to be a serious bodybuilder to use this?

No, it's built for anyone who needs extra calories, whether that's a dedicated bulk or just genuinely struggling to eat enough day to day.

For anyone who's tried to gain weight through food alone and hit a wall, Serious Mass makes hitting a calorie surplus far less of a daily grind.

Directions

Mix two scoops (334g) with 700–720ml of cold water or milk in a blender. Consume post-workout or between meals. Beginners may start with one scoop and gradually increase to two scoops per serve. This product is intended for healthy adults; always read the label, use only as directed, and seek medical advice if unsure.

Building it into your routine

Common questions

Can this replace a meal?

Yes, with 1250 calories and a full macro spread, it works well as a meal replacement on days you're short on time or appetite.

Will it make me gain fat instead of muscle?

Weight gain depends on training and total intake, not just this product, but pairing it with consistent resistance training is how the extra calories and protein get put to good use.

Do I need to be a serious bodybuilder to use this?

No, it's built for anyone who needs extra calories, whether that's a dedicated bulk or just genuinely struggling to eat enough day to day.

For anyone who's tried to gain weight through food alone and hit a wall, Serious Mass makes hitting a calorie surplus far less of a daily grind.

I'm excited!
I just started adding Serious Mass to my daily routines a few days ago and haven't seen any significant changes yet (of course lol). But, I know people who used/are using this for a long time and are happy with their gains hence, I tried it too. I'm excited to see my improvements 🤞
