An honest review of the Serious Mass Weight Gainer Protein Powder - Elite Series - 2.73kg, covering serving size, calorie density, taste profile, and mixability for hardgainers.

Gaining weight—especially lean muscle mass—can be just as challenging as losing it for many people. If you have a fast metabolism, a busy schedule, or simply struggle to eat enough calories through whole foods alone, a weight gainer supplement can be a convenient solution. The Serious Mass Weight Gainer Protein Powder - Elite Series - 2.73kg is one of the most popular options on the market, promising a dense calorie load per serving to help you bridge the gap between your maintenance intake and your muscle-building goals.

In this review, we’ll break down exactly what you get with the 2.73kg tub: the number of servings, the calorie and macronutrient profile, how it tastes when mixed with water or milk, and how well it mixes without clumps. We’ll also compare it to other mass gainers and protein supplements so you can decide if it’s the right fit for your bulking phase.

What Is Serious Mass Weight Gainer?

Serious Mass is a high-calorie weight gainer designed for individuals who need a significant calorie surplus to build mass. Each serving delivers a substantial amount of carbohydrates and protein, making it easier to consume the extra 1,000+ calories needed for muscle growth. The Elite Series version comes in a 2.73kg tub, which is a compact size ideal for those who want to test the product before committing to a larger container.

The formula is built around a blend of whey protein concentrate and maltodextrin, providing a mix of fast- and slow-digesting carbs. This makes it suitable for post-workout recovery or as a meal replacement when you’re short on time. Unlike some mass gainers that rely heavily on sugar, Serious Mass uses a carb matrix that aims to keep blood sugar levels more stable.

  • Calories per serving: approximately 1,250 (when mixed with water) or 1,600 (with whole milk)

Servings and Value: How Many Scoops in 2.73kg?

The 2.73kg tub contains 8 servings when using the recommended two-scoop serving size. Each serving provides 50g of protein and 250g of carbohydrates, totalling 1,250 calories. This makes it one of the most calorie-dense weight gainers per scoop on the market. If you prefer smaller servings, you can use one scoop (half a serving) for 625 calories, effectively doubling the number of servings to 16.

For those who want a more moderate calorie boost, pairing a half-serving with a meal can help you reach your daily surplus without feeling overly full. If you’re looking for a protein supplement with fewer carbs, you might also consider a product like the Gold Standard 100% Plant Based Protein Powder - Elite Series, which offers a leaner profile for muscle maintenance between meals.

  • Full serving (2 scoops): 1,250 calories, 50g protein, 250g carbs
  • Half serving (1 scoop): 625 calories, 25g protein, 125g carbs
  • 8 full servings or 16 half servings per 2.73kg tub

Taste and Flavour Options

The Serious Mass Weight Gainer comes in a few classic flavours, with chocolate being the most popular. The taste is rich and sweet, similar to a thick chocolate milkshake when mixed with milk. It does have a noticeable maltodextrin aftertaste, but most users find it pleasant enough to drink daily. If you prefer a lighter, fruitier option for your protein needs, the Essential AMIN.O. Energy Powder in Fruit Fusion is a refreshing alternative that also provides BCAAs and caffeine for pre-workout energy.

One common tip from users is to mix the powder with cold water or milk and let it sit for a minute before drinking—this allows the foam to settle and improves the overall mouthfeel. The sweetness level is high, so if you’re sensitive to artificial sweeteners, you might want to start with a half-serving to gauge your tolerance.

  • Best mixed with cold milk for a thicker, creamier shake
  • Chocolate flavour is the most popular; vanilla and strawberry also available

Mixability: Does It Clump or Leave Residue?

Mixability is a critical factor for any powder supplement, especially a mass gainer with a high carb content. Serious Mass mixes reasonably well with a shaker bottle, though you may encounter some clumping if you add all the powder at once. The best technique is to add liquid first, then the powder, and shake vigorously for 20–30 seconds. Using a blender bottle with a wire whisk ball helps break up any remaining lumps.

When mixed with water, the shake is thinner and may leave a slight gritty residue from the maltodextrin. With milk, it becomes much smoother and more palatable. For those who prefer a ready-to-drink option, the Gold Standard Pre-Workout Shot is a convenient alternative for a quick energy boost before training, though it doesn’t provide the same calorie density.

  • Use a blender for the smoothest consistency
  • Let the shake rest for 1 minute after shaking to reduce foam

If you’re a hardgainer looking for a convenient, calorie-dense way to support your bulking goals, the Serious Mass Weight Gainer Protein Powder - Elite Series - 2.73kg is a solid choice. It offers a high calorie count per serving, decent taste, and acceptable mixability for a mass gainer. Start with a half-serving to see how your body responds, and combine it with a consistent training programme for the best results. Explore the Serious Mass Weight Gainer Protein Powder - Elite Series - 2.73kg (8 Servings) to see if it fits your bulking plan.
