Serious Mass by Optimum Nutrition: A Comprehensive Review for Aussie Lifters Looking to Bulk Up

If you're finding it tough to put on weight, build lean muscle, or hit your daily calorie targets, you're definitely not alone. For many of us—especially those with fast metabolisms or hectic schedules—getting enough food in during the day can be a real challenge. That’s where mass gainers like Serious Mass by Optimum Nutrition come in.

Widely recognised in the fitness community, Serious Mass has built a solid reputation as a go-to supplement for anyone trying to bulk up. Whether you're a seasoned bodybuilder, a casual gym-goer, or just someone who struggles to keep weight on, this high-calorie shake could be the missing link in your nutrition plan.

What Is Serious Mass?

Serious Mass is a calorie-dense weight gainer shake designed to help users increase daily energy intake without having to prepare huge meals all day long. It’s a convenient and efficient way to fuel your body with the nutrients it needs for growth, recovery, and strength development.

Each serve (when mixed with water) contains:

• 1,250 calories to support weight gain and energy needs

• 50 grams of protein from a premium blend of whey, casein, and egg protein

• 252 grams of carbohydrates to restore energy and support muscle glycogen

• Low fat content, focusing on lean mass gains

• Over 25 essential vitamins and minerals to round out your nutrition

And that’s just when you mix it with water—add full-cream milk, bananas, peanut butter or oats, and you’ll easily push your intake well above 1,500 calories per shake.

Flavours and Versatility

Taste plays a big part when choosing a supplement, especially one you’ll be drinking daily. Serious Mass is available in several flavours, including Chocolate, Vanilla, and Strawberry. Chocolate tends to be the most popular for its rich, dessert-like profile, while Vanilla offers a great base for smoothie-style shakes and custom blends. Strawberry is a lighter, fruity option that suits those looking for a change from the usual sweet flavours.

The shake mixes best in a blender, which helps achieve a smoother texture and prevents clumping. If you're using a shaker bottle, add the liquid first and slowly mix in the powder to get the best result.

How It Performs

When it comes to delivering on its promise, Serious Mass holds up well—especially when combined with a consistent gym routine and a balanced diet.

Here’s what you can expect:

• Muscle Growth: The high-quality protein blend supports muscle repair and development after your workouts.

• Improved Recovery: With over 250 grams of carbs, it helps refill glycogen stores, which boosts post-training recovery and energy for your next session.

• Weight Gain Support: For hard gainers or naturally lean individuals, the extra calories provide a much-needed boost to tip the scales in the right direction.

How to Use It

If you’re just getting started with mass gainers, it’s smart to begin with a half serving to gauge how your body reacts. A full serve is quite heavy and may feel like a meal on its own. Once you’re used to it, you can increase to the full amount or split it across the day.

Pro tip: For extra calories and nutrients, blend it with full-cream milk, a banana, a tablespoon of peanut butter, or even a handful of oats. This creates a more filling, nutrient-dense shake that supports serious muscle building.

Ideal times to take Serious Mass include post-workout, when your body needs quick nourishment, or between meals to keep your energy levels up and avoid feeling sluggish or hungry during the day.

Pros of Serious Mass

• Packed with calories, making it ideal for anyone struggling to gain weight

• Balanced blend of protein, carbs, and micronutrients for overall support

• Versatile in flavours and easy to customise

• Great value for the calorie and nutrient content

Potential Downsides

• Contains around 20g of sugar per serve, which might be a concern for some

• The large serving size can be difficult for those with smaller appetites

• May cause bloating or mild digestive discomfort in those sensitive to dairy or large meals

Final Verdict

Overall, Serious Mass by Optimum Nutrition is a solid choice for Aussies looking to increase their size, strength, or overall calorie intake. It's especially helpful for hard gainers or anyone entering a bulking phase of training. The high calorie count, quality ingredients, and reliable brand name make it a supplement worth considering.

Just remember: while Serious Mass can make your journey easier, it's not a magic fix. For the best results, combine it with proper training, a solid food plan, and consistent sleep and recovery habits.

Whether you’re trying to build muscle, break through a plateau, or simply eat more without feeling stuffed all day, Serious Mass could be the perfect addition to your nutrition toolbox.
