10 Best Supplements To Put On Muscle Mass in 2026

A single serving packs 1020 calories, 55 grams of protein, and 13 grams of BCAAs, numbers that make it clear this is built for people who genuinely struggle to add weight. The multi-source protein blend combines whey concentrate, whey isolate, calcium caseinate, and egg white albumin. This gives you both fast-digesting amino acids right after your workout and slow-release proteins that keep feeding your muscles for hours. It is a formula designed for the hardgainer who has tried everything and needs a calorie-dense, reliable option to finally push the scale upward.

The sheer volume you have to consume is a trade-off here: four scoops mixed with 18 ounces of liquid makes for a hefty shake, and the 162-gram carb matrix relies on maltodextrin and crystalline fructose to replenish glycogen stores. Compared to the Optimum Nutrition Serious Mass, which includes creatine and glutamine per its label, the Muscle Juice provides a multi-source protein blend and MCT fat rather than those added ingredients. If you prefer a mass gainer with fewer calories and carbs, the GHOST Clear Gains offers 440 calories and 40 grams of whey isolate per serving. But for those who need maximum calories and sustained protein delivery in a four-scoop serving, this is a straightforward option.

With 1,280 calories and 52 grams of protein in a single serving, this supplement provides a dense caloric boost when your appetite can’t keep up with your goals. The whey and casein blend delivers protein from two sources, and the 1 gram of creatine per serving supports power and strength as part of your training routine. For anyone aiming to increase muscle mass and meet energy needs, this formula simplifies the process.

The trade-off is real: 245 grams of carbs per serving is a lot, even for a mass gainer. So if you’re someone who watches carb intake or feels sluggish after heavy meals, this might sit heavier than some other options. You also only get eight servings per container, which means you’ll need to plan your purchases accordingly. But if your main challenge is simply getting enough fuel to grow, this mix of protein, creatine, and calories provides a straightforward solution.

The carb load is the trade-off. At over 250 grams per serving, this is a serious carb bomb, which works great if you’re burning through energy in heavy training sessions but less so if you’re watching your carbohydrate intake for other reasons. Compare it to Dymatize Super Mass Gainer, which delivers 1,280 calories with 245 grams of carbs. Serious Mass is the classic high-calorie option for lifters who want a no-fuss, calorie-dense shake that can be customized with milk or peanut butter without worrying about the math.

With 440 calories and 40 grams of whey protein isolate per serving, this gainer is built for clean, steady muscle building without the heavy, syrupy feeling of traditional mass powders. The zero fat and no added sugar mean you get your calories from protein and Vitargo carbs rather than extra fillers, which makes it a smart pick if you want to add size without loading up on fats or processed sugars. It suits anyone who finds thick, milky gainers hard to stomach and prefers a lighter, refreshing drink that still delivers real protein numbers.

At 440 calories per two-scoop serving, this is a lighter mass gainer compared to something like Ultimate Nutrition Muscle Juice 2544, which packs 1,020 calories per serving. That lower calorie count makes it a better fit for someone who wants post-workout recovery without a heavy, sluggish feeling. The formula is completely transparent, with every ingredient dose listed on the label, so you know exactly what you’re putting in your body.

Fifty grams of protein and 1,250 calories per serving is a serious calorie boost for anyone struggling to pack on mass, and the ingredient list is refreshingly short: grass-fed whey, micellar casein, and organic tapioca maltodextrin. That means no artificial sweeteners, no soy, no gluten, and no mystery fillers, just clean fuel that works with your body instead of against it. If you want a mass gainer that lets you control what goes into your shake, this is the one to reach for.

Because it’s unflavored, you’ll need to blend it with fruit, peanut butter, or cocoa to make it taste like something you actually want to drink. For the hard gainer who prioritizes ingredient transparency over convenience, this is a smart, honest choice.

With 1,100 calories and 56 grams of protein per serving, this mass gainer is designed for anyone who needs a high-calorie boost to support weight gain and active lifestyles. The ingredient list includes barley, sweet potato, rolled oats, avocado, coconut oil, flaxseed, pumpkin seed, and sunflower oil, which are whole-food sources. That means the fats and carbs come from recognizable ingredients, which can feel more like a meal replacement than a shake for some users. It’s ideal for hardgainers who want steady weight gain without relying solely on processed fillers.

Each pouch delivers 16 servings, so daily use means frequent reordering. The 1,100 calories per serving come from ingredients like barley, sweet potato, rolled oats, avocado, coconut oil, flaxseed, pumpkin seed, and sunflower oil. That whole-food blend provides a carb profile based on real ingredients rather than simple sugars. For someone with a smaller appetite, splitting a serving into two shakes across the day could make the calorie target more manageable.

Zero fat and zero sugar per serving sets this mass gainer apart from many competitors. That means you get 50 grams of beef protein isolate and over 700 calories without any of the dairy or extra fillers that can upset sensitive stomachs. It is a smart option if lactose has kept you away from traditional weight gainers, or if you want a cleaner macronutrient profile that skips the bloat. The beef protein isolate is also 350 percent more concentrated in amino acids than steak, so your muscles get a fast-absorbing boost without the fat or cholesterol.

The 125 grams of carbs per serving make this a serious calorie bomb for hard gainers or post-workout refueling, not casual sipping. Compared to Dymatize Super Mass Gainer’s 245 grams of carbs, CARNIVOR is actually lower in total carbs, but it still delivers enough carbohydrates to support the high-speed macronutrient delivery described in the product’s feature list. If you are watching your carbohydrate intake or prefer a leaner gainer, the high carb count might feel heavy. For anyone who needs a lactose-free, no-fat option to build mass without digestive drama, this fits the bill.

Mixed with 2 cups of skim milk, each serving packs 60 grams of protein and 1,500 calories, plus HPLC-tested creatine monohydrate. That gives you both the building blocks for muscle and the fuel for strength in one shake, so you don’t have to juggle multiple powders. Scientific studies show creatine helps replenish ATP stores for enhanced performance, more muscle, and an increase in strength.

The trade-off is the serving size, six scoops plus two cups of skim milk is a lot of volume to drink in one go. If you prefer a smaller, more frequent eating schedule, something like Dymatize Super Mass Gainer offers a lower 1,280-calorie serving that might feel less heavy. But for anyone who wants a straightforward, high-calorie mass gainer with creatine already mixed in, this tub covers the basics efficiently.

With over 1,220 calories and 40 grams of all-whey protein per serving, this mass gainer packs a serious caloric punch for anyone struggling to add size. The 6:1 carb-to-protein ratio leans heavily on carbs, which makes sense if your goal is rapid weight gain and you train hard enough to use that energy. The whey protein brings 9 grams of naturally occurring BCAAs, plus there’s pure creatine monohydrate mixed in, so you get two muscle-building helpers in one scoop. It’s a straightforward, no-nonsense formula for lifters who want a high-calorie shake that supports recovery and growth without extra frills.

A carb load of 250+ grams per serving means this isn’t a light sipper, it’s a substantial shake that works best when you’re committed to a high-calorie diet and intense training. Compared to something like GHOST Clear Gains, which keeps carbs lower at 70g, Rule 1’s offering is clearly aimed at the hardgainer who needs maximum calories in a single drink. You’ll also need to mix two scoops with 18-20 ounces of liquid, so it’s not a quick on-the-go option. If your priority is a clean, whey-based mass gainer with added creatine and you can handle the carb load, this fits the bill.

Fifty grams of protein per serving is a serious starting point for anyone trying to pack on muscle without blending half a dozen scoops. Nutricost Mass Gainer pairs that protein with creatine monohydrate and L-glutamine, two ingredients that support strength and recovery, so you’re not just drinking empty calories. It delivers a straightforward weight gainer with a solid protein hit and extra muscle-building helpers in one tub.

Each 6.7-pound container holds nine servings, so you’ll be ordering again sooner than you would with a larger tub like the Ultimate Nutrition Muscle Juice 2544. That container weighs 10 pounds and provides more servings per purchase. For someone who goes through mass gainer quickly, the smaller size might mean more frequent reorders and potentially higher long-term cost. On the other hand, the compact 7.3-pound package is easier to store and carry than bulkier options. Reviewers note that the trade-off in serving count is something to consider if you prefer buying in larger quantities to reduce how often you restock.
