The BSN True-Mass Weight Gainer in Chocolate Milkshake is a high-calorie supplement designed for athletes and hardgainers who struggle to add mass. Each serving packs 690 calories, 47 grams of protein, and a 2:1 ratio of carbs to protein, making it a potent tool for extreme training programs.

What sets this formula apart is its ultra-premium protein blend, which includes whey concentrate, calcium caseinate, milk protein isolate, whey isolate, micellar casein, hydrolyzed whey, and egg whites. This variety ensures a steady release of amino acids to support muscle recovery and growth over hours. The addition of MCTs provides healthy fats for extra energy without compromising taste.

BSN's flavor technology delivers a rich, milkshake-like experience that mixes smoothly with water or milk, making it enjoyable to drink consistently. The 5.82-pound tub offers 16 servings, which is sufficient for a month of daily use if used as directed. Users report good mixability and a satisfying texture that doesn't clump.

On the downside, the high calorie count may be excessive for those not engaged in intense training, and the dairy-heavy protein sources make it unsuitable for vegans or individuals with lactose sensitivity. The price is also on the higher end compared to basic weight gainers, but the quality of ingredients justifies the cost for serious users.

Detailed Review

The BSN True-Mass 1200 is an ultra-premium super mass gainer designed for athletes and individuals who struggle to gain weight despite intense training. With a massive 1200 calories per serving, it targets those who need a high-calorie boost to pack on muscle mass efficiently.

Its standout feature is the 4:1 carbohydrate to protein ratio, which provides sustained energy for workouts while delivering 50g of multi-source protein including BCAAs. The addition of 8g of fiber per serving is a thoughtful touch, helping to improve digestion and reduce bloating often associated with high-calorie shakes.

In real-world use, the powder mixes reasonably well with water or milk, though achieving a smooth consistency may require a blender due to the high calorie density. The taste is decent for a mass gainer, though individual preferences vary. BSN has a solid reputation for supplement quality, and this formula reflects their commitment to serious results.

A potential drawback is the calorie overload for less active individuals; it is clearly aimed at hardgainers and intense training regimens. Additionally, the price point is premium, reflecting the high-quality ingredients and specialized formulation. Those on a budget might find cheaper alternatives, but they often lack the fiber and protein blend.

Overall, the BSN True-Mass 1200 is a top-tier choice for anyone committed to extreme mass gains. It delivers on its promises with high calories, balanced macros, and digestive support, making it a reliable option for serious lifters and athletes.

Detailed Review

Each serving delivers 690 calories, 50 grams of premium protein, and a 2:1 ratio of carbs to protein to support intense training and muscle recovery. This Vanilla Ice Cream flavor offers a delicious, milkshake-like taste that makes sticking to your mass-gain goals easy.

The standout feature is its ultra-premium protein blend, incorporating whey concentrate, calcium caseinate, milk protein isolate, whey isolate, micellar casein, hydrolyzed whey, and egg whites.

Real-world performance is impressive, with smooth mixing and no chalky aftertaste, even when blended with water or milk.

Design and build quality reflect BSN's reputation. The 5.82-pound tub is resealable and easy to store. The powder has a fine consistency that dissolves well in a shaker bottle. BSN's flavor technology lives up to its name, delivering a creamy texture that rivals a real ice cream shake, without artificial aftertaste.

A potential drawback is the serving size, which may be bulky for some users to consume in one sitting. Additionally, the formula contains milk and eggs, so it is not suitable for those with allergies. The carb count, while ideal for bulking, may be higher than what those seeking lean mass or on low-carb diets prefer.

Overall, BSN True-Mass is a top-tier weight gainer that delivers on its promises. Its exceptional taste, high-quality protein blend, and calorie density make it an excellent choice for hardgainers and serious lifters.

Detailed Review

BSN True-Mass is a premium weight gainer designed specifically for athletes and hardgainers who struggle to consume enough calories to build muscle. Each serving packs a massive 1200 calories, making it one of the most calorie-dense products on the market. If you have a high metabolism or simply find it difficult to eat enough, this shake can be a convenient way to add significant calories to your diet.

The standout feature is the 4:1 carbohydrate to protein ratio. This ensures that your body gets the carbs it needs for energy and glycogen replenishment, while the 50g of multi-source protein provides a steady stream of amino acids to support muscle repair and growth. The inclusion of BCAAs and other essential amino acids further enhances its muscle-building potential.

In terms of quality, BSN has a solid reputation for producing effective sports nutrition products. The chocolate milkshake flavor is generally well-received, and the powder mixes reasonably well with water or milk, though it tends to be thick due to the high calorie content. The 10g of fiber per serving is a thoughtful addition, aiding digestion and helping you feel satisfied after each shake.

However, there are a few drawbacks to consider. The calorie count is extremely high, so if you are not careful, you may gain unwanted fat along with muscle. Also, the serving size is large, which can be a bit of a chore to consume daily. Additionally, the price per serving is higher than many other weight gainers, but the quality and effectiveness may justify the cost for serious lifters.

Overall, BSN True-Mass is an excellent choice for anyone looking to bulk up significantly. It is not for the casual user or those watching their calorie intake, but for dedicated athletes who need a convenient, high-calorie shake to meet their goals, it delivers on all fronts. I would recommend it to hardgainers and advanced trainees who are serious about gaining mass.

Detailed Review

BSN True-Mass Weight Gainer is a serious tool for athletes and hardgainers who struggle to pack on weight despite eating regular meals. Each serving delivers a colossal 1200 calories, making it one of the most calorie-dense weight gainers on the market. This is not a meal replacement; it's a targeted supplement for those with high caloric needs, such as bodybuilders in a bulking phase or endurance athletes looking to maintain mass during heavy training blocks.

The formula's 4:1 carb-to-protein ratio is thoughtfully designed to replenish glycogen stores post-workout while providing a steady supply of protein to support muscle repair and growth. The 50g multi-source protein matrix, which includes whey, casein, and egg, ensures both fast and slow-digesting proteins, giving you a sustained anabolic effect. The inclusion of 7g of fiber per serving is a standout feature, as it helps mitigate the digestive discomfort often associated with high-calorie shakes.

In terms of taste and mixability, the Vanilla Ice Cream flavor is a crowd-pleaser, though it's quite sweet and may be overpowering for some. The powder mixes fairly well with just a shaker, though a blender is recommended for a smoother consistency. The container is large and sturdy, but the scoop size is substantial, so be prepared for a big shake.

On the downside, the price per serving is higher than many competitors, which might be a dealbreaker for budget-conscious buyers. Additionally, the sheer volume of liquid required to mix a full serving can be challenging to consume, especially for those with a smaller appetite. Some users might also prefer a lower-carb formula, as this is heavily carb-loaded.

Overall, BSN True-Mass is a top-tier weight gainer that delivers on its promises. It's ideal for anyone who needs a high-quality, high-calorie supplement to fuel serious muscle gains. While it's not cheap and requires commitment to drink, its nutritional profile and effectiveness make it a solid investment for those serious about packing on mass.

Buying Guide

Calorie Content: How Many Calories You Need

Mass gainers vary widely in calorie count per serving. For extreme bulking, a 1200-calorie shake like BSN True Mass 1200 provides a dense calorie surplus in one drink. If you prefer a more moderate approach, a 690-calorie option lets you add calories without overshooting your daily needs. Choose based on your current weight and activity level.

For more on tailoring your nutrition, read our guide on sports nutrition for performance.

Carb to Protein Ratio: Finding the Right Mix

The ratio of carbohydrates to protein affects how your body uses the shake. A 4:1 ratio delivers more energy for workouts and replenishes glycogen stores, ideal for post-training recovery. A 2:1 ratio offers a higher protein percentage, supporting muscle synthesis while still providing carbs. Pick the ratio that aligns with your training intensity and dietary preferences.

Check out our isopure low carb protein review for an alternative low-carb option.

Protein Sources and Amino Acid Profile

High-quality mass gainers use a blend of fast and slow-digesting proteins. BSN True Mass features whey protein concentrate, calcium caseinate, milk protein isolate, micellar casein, and egg whites. This multi-source matrix ensures a sustained release of amino acids, including branched-chain amino acids (BCAAs) for muscle recovery. Look for at least 47 to 50 grams of protein per serving for serious gains.

Flavor and Mixability

No one wants to choke down a grainy, chalky shake. BSN adds MCT fats and advanced flavor technology for a milkshake-like texture. Options like Chocolate Milkshake and Vanilla Ice Cream mix smoothly with water or milk. Always check customer feedback on flavor if taste is a priority for you.

Final Thoughts

Whether you need a massive calorie punch or a balanced daily gainer, BSN True Mass has a formula for you. For extreme bulking, the BSN True-Mass Weight Gainer Protein Powder (Chocolate Milkshake, 1200 calories) delivers maximum calories in a delicious shake. If you prefer a moderate approach with great taste, the BSN True-Mass Weight Gainer Protein Powder (Vanilla Ice Cream, 690 calories) provides a high-protein blend that mixes like a dream. Both are top choices backed by BSN’s trusted quality.
