With 1,280 calories and 52g of protein per serving, it targets serious athletes and hardgainers looking for a convenient way to increase their daily intake.

- Strong protein blend (52g) with BCAAs for muscle recovery
- Delicious Fruity Pebbles flavor, a welcome change from typical mass gainers
- Includes 14 vitamins and minerals for added nutritional support
- Convenient single-tub packaging for easy portioning
Cons
- At 1290 calories and 248g carbs per serving, it may be too calorie-dense for those not looking to gain significant weight
- Only 10 servings per 6-pound tub, so value may be lower for some users
- May cause bloating or digestive discomfort in those sensitive to dairy or high-carb shakes
Dymatize Super Mass Gainer is a high-calorie weight-gain supplement designed for individuals who struggle to put on mass despite eating frequently. This 6-pound tub, flavored with Fruity Pebbles, is a serious tool for hardgainers, athletes, and anyone looking to significantly increase their daily caloric intake to support muscle growth.
At 1290 calories and 248g of carbs per serving, this powder is engineered to create a massive caloric surplus. It combines a fast and slow digesting protein blend (52g) to deliver a steady stream of amino acids, supporting both rapid recovery and prolonged anabolic response. The added 10.7g of BCAAs, including 5.1g of Leucine, further enhances muscle protein synthesis, making it an effective post-workout or between-meal shake.
The Fruity Pebbles flavor is a standout, offering a sweet, nostalgic taste that is often rare in mass gainers known for being heavy or chalky. The powder mixes well with water or milk, though it can be thick if you follow the full serving size. The tub is sturdy and resealable, maintaining freshness, though the 6-pound size means you'll need to reorder frequently if you use it daily.
While the high calorie and carb content is ideal for bulking, it's not for everyone. Those who are not serious about gaining weight may find it excessive, and the high dairy content could cause digestive issues for lactose-intolerant individuals. Additionally, at only 10 servings per tub, the price per serving is relatively high, but the effectiveness for hardgainers often justifies the cost.
Overall, Dymatize Super Mass Gainer is a top-tier choice for anyone who needs a calorie-dense, protein-packed shake to fuel serious mass gains. It's best suited for athletes and hardgainers who are committed to gaining muscle weight and are willing to invest in a quality supplement. With its great taste and solid nutritional profile, it's a strong contender in the mass gainer market.

The added vitamins and minerals further enhance its nutritional profile, making it a comprehensive option for bulking phases.
The product comes in a 6-pound container with a vanilla flavor that mixes easily with water or milk.

A potential drawback is the high serving size, which may feel heavy or cause bloating for some users. The carbohydrate content is also significant, so it may not be ideal for those on low-carb diets.

- 52g protein per serving supports muscle repair and growth
- Blend of fast and slow proteins ensures long-lasting amino acid delivery
- Creatine added to boost strength and power output

Dymatize Super Mass Gainer is a serious weight gainer designed for individuals who struggle to put on muscle mass and need a dense source of calories and protein. With a hefty 1,280 calories and 52g of protein per serving, it targets hardgainers, athletes in a bulking phase, or anyone needing extra energy to support intense training. This powder is particularly beneficial for those who have high metabolisms and find it challenging to consume enough food to gain weight.
The standout feature is its dual-protein blend of whey and casein. Whey provides a quick spike of amino acids post-workout, while casein digests slowly, ensuring a steady supply of protein to muscles over several hours. This makes it ideal for use between meals or as a post-workout shake. Additionally, the inclusion of 1g of creatine per serving supports strength gains, helping you lift heavier and train harder. The added vitamins and minerals, including Vitamin C, E, and calcium, support overall health and recovery, making it a well-rounded supplement.
In terms of mixability and taste, the Rich Chocolate flavor is generally well-received, though some users might find it slightly sweet. It blends well with water or milk, and the powder is versatile enough to be incorporated into recipes like pancakes, cookies, or smoothies. The 12 lb tub is generous, offering roughly 8 servings, which provides good value for the price. The packaging is sturdy, though the large size might be cumbersome for some.
However, there are a few considerations. The high calorie count might be excessive for those who are not training heavily or have lower daily energy requirements. Additionally, the product contains a variety of ingredients, including artificial flavors and sweeteners, which could be a concern for those with sensitivities or who prefer clean labels. It's also worth noting that each serving is large, so you'll need to mix it with a good amount of liquid to avoid a thick consistency.
Overall, Dymatize Super Mass Gainer is a powerful tool for anyone serious about gaining muscle mass. It delivers on its promises of high protein, calories, and added strength benefits. While it may not suit everyone due to its caloric density and ingredient list, for the target audience of hardgainers and athletes, it's an excellent choice. The blend of fast and slow proteins, combined with creatine and vitamins, makes it a comprehensive supplement for bulking phases. If you're looking to pack on size and have the appetite for it, this is a top contender.

With over 1,200 calories per two-scoop serving, it delivers a massive energy boost that helps bridge the gap between a typical diet and the demands of muscle building. This product is especially suited for hardgainers, athletes, and anyone looking to increase their caloric intake efficiently.
The standout feature is its comprehensive nutritional profile: 50 grams of blended protein, including whey and casein, provide both immediate and sustained amino acid release. Over 250 grams of carbohydrates help refill glycogen stores, while 20+ vitamins and minerals add immune support and overall wellness. Real-world performance is consistent with Optimum Nutrition's reputation for quality, mixing smoothly when using an electric blender or shaker.
Design and build quality are typical for a large supplement tub. The 12-pound container is sturdy and includes a scoop for accurate dosing. The chocolate flavor is palatable and mixes well with milk, water, or added ingredients like fruits and nut butters. The powder's texture can be slightly gritty if not mixed thoroughly, but this is common for high-calorie gainers.
One drawback is the high carbohydrate content, which may not fit low-carb or ketogenic diets. Additionally, the serving size requires a significant amount of liquid to achieve a drinkable consistency. Some users may find the tub cumbersome to store due to its size. However, for its intended purpose of mass gain, these are minor trade-offs.
Verdict: Optimum Nutrition Serious Mass is a reliable, high-calorie weight gainer that delivers on its promises. It is best for those who need a convenient, nutrient-dense shake to support muscle growth and weight gain.
