10 Best Protein Powders For Bulking in 2026

The 245 grams of carbs per serving is a lot, even for serious bulking. If you fill out easily or prefer a leaner approach, Optimum Nutrition Serious Mass comes in a 6-pound tub that weighs 2.0 pounds, heavier than this 1.3-pound container, so the portability differs. Still, for anyone who wants maximum calories and protein in one scoop without extra ingredients, this option delivers exactly what it promises.

The addition of creatine, glutamine, and BCAAs means you’re getting more than just calories, these extras help support muscle recovery and strength gains after tough workouts. It also packs over 250 grams of carbs to refill glycogen stores and fuel your next session, plus 20+ vitamins and minerals to cover daily nutrition gaps. That makes it a practical choice for anyone in a hard bulking phase who wants a complete, high-calorie shake without hunting down separate supplements.

It’s designed for the person who needs a big calorie surplus and doesn’t mind the heavier feel. Compared to the NAKED Mass Natural Weight Gainer, which uses simpler, whole-food ingredients, Serious Mass leans into a more complete formula with added performance nutrients. If your goal is pure size and you want everything in one scoop, this is your pick. If you prefer a cleaner ingredient list, you might lean toward NAKED Mass instead.

Fifty grams of protein per serving is a solid start, but what really sets this mass gainer apart is that it packs 1,250 calories using just three ingredients: whey, casein, and organic tapioca maltodextrin. That means no artificial sweeteners, no soy, no gluten, and no guessing about what you are putting in your body. The multi-phase protein blend keeps muscle synthesis going longer, so you get steady support between meals rather than a quick spike and drop. For anyone who wants a clean, straightforward way to add serious calories without the chemical laundry list, this is a refreshing option.

The 252g of carbs per serving are a lot, even by bulking standards. If you are watching your carb intake or prefer a leaner gain, something like Transparent Labs Mass Gainer with 110g of carbs might be a better fit. Because Naked Mass is unflavored, reviewers report they blend it with milk, fruit, or cocoa to make it taste like anything beyond neutral. That said, if your goal is pure, honest weight gain from a short ingredient list, this tub delivers exactly what it promises.

With 770 calories per serving from oat flour, sweet potato powder, and organic tapioca maltodextrin, this mass gainer focuses on clean, whole-food ingredients rather than cheap fillers. The 53 grams of grass-fed whey provide a complete amino acid profile to support muscle protein synthesis, and the added 3 grams of creatine monohydrate gives you a clinically dosed boost for strength and recovery. If you want a mass gainer that skips artificial sweeteners and colors while still delivering serious calories, this one fits that bill nicely.

You get only 15 servings per container, so if you plan to use it daily, you will need to reorder frequently. Compared to Dymatize Super Mass Gainer, which packs 1,280 calories and 245g of carbs per serving, Transparent Labs offers a more moderate carb load. That might work better for someone who wants to control their carbohydrate intake while still hitting a caloric surplus. It is a premium pick for those who prioritize ingredient quality over sheer volume.

With up to 1,270 calories per serving, this is built for the hard gainer who struggles to pack on weight even with big meals. The multi-source protein blend delivers 46 grams to support muscle repair, while complex carbs from barley, sweet potato, and rolled oats provide steady energy instead of a sugar spike. It’s a dense, no-nonsense shake for anyone who needs serious calorie density without resorting to junk food fillers.

With up to 1,270 calories per serving, this is a serious tool for anyone who struggles to pack on weight. But that much fuel in one scoop can feel heavy if your appetite isn’t already dialed in. It delivers 46 grams of protein from a multi-source blend, which supports muscle recovery after workouts. If you prefer a mass gainer with more flavor variety, you might look elsewhere, but for the person who needs pure, high-calorie support in a single shake, this gets the job done.

A single serving delivers 60g of protein and 1,500 calories, making this one of the densest mass gainers you can buy. That HPLC-tested creatine monohydrate is a smart addition for anyone serious about packing on strength alongside size, since creatine helps replenish ATP stores for better performance in the gym. It suits lifters who want a complete bulking shake with extra muscle-fueling ingredients like 6.3g of L-leucine and over 13g of BCAAs.

The serving size is the catch: six scoops per shake means you are committing to a big drink and a lot of carbs (304g). If you prefer a mass gainer with fewer carbs, Dymatize Super Mass Gainer provides 1,280 calories and 245g carbs per serving.

With over 1,220 calories, more than 250 grams of carbohydrates, and 40 grams of all-whey protein per serving, this mass gainer is designed for anyone who needs a straightforward way to add serious calories. The 6:1 carb-to-protein ratio delivers a heavy energy load to fuel intense training sessions, while the added pure creatine monohydrate supports strength without requiring a separate supplement. It takes the guesswork out of hitting a calorie surplus, making it a practical option for those focused on aggressive mass gain rather than lean maintenance.

That carb count can feel overwhelming if your metabolism isn’t already running hot. Compared to something like Dymatize Super Mass Gainer, which lands at 245g carbs per serving, Rule 1 sits at the higher end of the spectrum. That means it works best when your goal is aggressive mass gain, not lean maintenance. Mixing two scoops with 18-20 ounces of liquid also makes for a hefty shake, so plan on a bigger glass or a blender if you want to add fruit.

With 1260 calories and 50 grams of protein per serving, this tub provides a high-calorie, high-protein option for those looking to gain mass. The carbohydrate blend includes oats, yams, and sweet potatoes, as listed on the label, offering a natural carb source. The 12-pound tub contains at least 16 servings, which reduces how often you need to reorder compared to smaller containers.

Each shake requires four scoops, so mixing takes a bit more effort and the carb count at 250g per serving may feel heavy for anyone who prefers a leaner ratio. Compared to Dymatize Super Mass Gainer, which offers 1,280 calories per serving in a 6-pound tub, this Forzagen option provides a larger total volume for those who want to buy in bulk. It suits someone who knows they want a big, calorie-dense shake and values buying in bulk over variety in flavors.

Twenty grams of protein per scoop means this whey gives you a solid, clean hit of muscle fuel without loading up on extra carbs or sugar. It’s built for steady lean growth and recovery, with over 4.6 grams of naturally occurring BCAAs to help repair tissue after a tough session. If your goal is to add quality mass without a calorie bomb, this fits right into a balanced bulking plan where you control the rest of your food intake.

With 20 grams of protein per scoop and only 1 gram of sugar, this whey protein is designed for lean muscle support rather than rapid weight gain. Unlike mass gainers such as Dymatize Super Mass Gainer, which pack 52 grams of protein and 245g of carbs per serving, this formula keeps calories lower. That way you can control your total intake while still getting a quality protein boost. Reviewers find it works well for pre- and post-workout recovery without the heavy carb load.

At 50 grams of protein from beef isolate per serving, this mass gainer delivers a concentrated amino acid profile that’s 350% more concentrated in amino acids than steak, according to the manufacturer, and it’s lactose free. That makes it a smart choice if dairy bothers your stomach but you still want serious calorie support for bulking. With over 700 calories and zero fat or sugar, you get 125g of carbs per serving for energy without the dairy that some blends contain.

The carb count of 125g per scoop is on the higher side, so if you’re watching carb intake or prefer a leaner gainer, you might look at something like Transparent Labs Mass Gainer with 110g carbs. But for anyone who needs a lactose-free option that still packs a dense protein punch, this beef-based formula is one of the few mass gainers that avoids dairy entirely.
