Wondering how many servings are in a 2.73kg Serious Mass tub? This guide breaks down the scoop size, calorie per serving, and dosage tips to help you bulk effectively.
If you’re on a serious bulking journey, you’ve probably come across the Serious Mass weight gainer from Optimum Nutrition. It’s a popular choice for those looking to add quality mass, thanks to its high calorie and protein content per serving. But one common question that arises when you buy the 2.73kg tub is: exactly how many servings does it contain?
Knowing the number of servings helps you plan your nutrition, budget your supplement purchases, and ensure you’re hitting your daily calorie surplus consistently. In this guide, we’ll break down the serving size, scoop measurements, and practical tips for using Serious Mass effectively.
Understanding the Serving Size of Serious Mass 2.73kg
The Serious Mass 2.73kg tub is designed to provide a hefty dose of calories and protein per serving. According to the official nutrition label, a single serving of Serious Mass is 2 heaped scoops, which equates to approximately 335g of powder. This yields about 1,250 calories, 50g of protein, and 252g of carbohydrates when mixed with water. If you mix it with milk, the calorie count increases further.
Given that the total net weight is 2.73kg (or 2,730g), you can calculate the number of servings by dividing the total weight by the serving size. 2,730g ÷ 335g equals roughly 8.15 servings. So, you can expect around 8 full servings per tub, with a little leftover powder for a partial serving. This is important to keep in mind when planning your monthly supplement intake.
- One serving = 2 heaped scoops (335g powder) = 1,250 calories with water.
- Total servings per 2.73kg tub: approximately 8 servings.
- Always use the scoop provided and level it for consistency.
How to Measure Your Mass Gainer Scoop Accurately
Getting the right dosage is key to achieving your bulking goals without wasting product. The Serious Mass tub comes with a large scoop that holds about 167g when heaped. Since the recommended serving is 2 heaped scoops, you’ll want to fill the scoop generously and then level it off with a knife or the tub’s built-in scraper. Avoid packing the powder down, as that can lead to an uneven dose.
If you’re using a digital kitchen scale, you can weigh out 335g of powder for absolute precision. This is especially helpful if you’re splitting your servings across multiple shakes throughout the day. For example, you might take half a serving (1 scoop) post-workout and another half later. Just remember that the calorie and protein values will be halved accordingly.
- Use the scoop provided: 1 heaped scoop ≈ 167g.
- For half servings, use 1 scoop (approx. 625 calories).
- Weighing the powder ensures accurate macros every time.
Calorie Per Serving and Bulking Strategy
With 1,250 calories per serving, Serious Mass is one of the most calorie-dense weight gainers on the market. This makes it ideal for hardgainers who struggle to eat enough whole foods. To maximize results, consider having one serving between meals or immediately after your workout. Pair it with a solid training program and a balanced diet to ensure the extra calories go toward muscle, not just fat.
For those who find a full serving too heavy, you can split it into two smaller shakes. For example, have one scoop (about 625 calories) in the morning and another post-workout. This approach can improve digestion and keep your energy levels stable throughout the day. Remember, consistency is more important than perfection when it comes to bulking.
- 1 full serving = 1,250 calories (with water).
- Splitting into 2 half-servings can aid digestion.
- Combine with strength training for optimal muscle gain.
Tips for Getting the Most Out of Your Serious Mass Tub
To make your 2.73kg tub last as intended, store the powder in a cool, dry place and keep the lid tightly sealed after each use. Moisture can cause clumping, which makes scooping difficult and may affect freshness. If you travel frequently, consider portioning out individual servings in zip-lock bags or small containers for convenience.
You can also enhance the taste and nutritional profile by adding ingredients like peanut butter, bananas, or a scoop of your favorite protein powder. For instance, mixing Serious Mass with a scoop of Gold Standard 100% Whey Protein Powder Sachets can boost the protein content even further. Just be mindful of the total calories if you’re adding extras.
- Store in a cool, dry place to prevent clumping.
- Pre-portion servings for on-the-go convenience.
- Add nut butter or fruit for extra flavor and nutrients.
Now that you know there are about 8 servings in a 2.73kg tub of Serious Mass, you can plan your bulking phase with confidence. Whether you’re a hardgainer or just looking to add size, this weight gainer delivers the calories and protein you need. If you’re ready to start your journey, explore the Serious Mass 2.73kg and pair it with a solid training plan for the best results.
