9 Best Workout Supplements To Gain Mass in 2026

With 1,200 calories per two-scoop serving, this weight gainer packs enough energy to support serious bulking when your regular meals just aren’t cutting it. The 50 grams of blended protein, including whey, creatine, glutamine, and BCAAs, gives your muscles the building blocks they need to repair and grow after heavy training. Over 250 grams of carbohydrates help replenish glycogen stores and keep you fueled through long sessions. It’s a straightforward, high-calorie option that works well for anyone who struggles to eat enough whole food to gain size, especially during intense training phases.

The trade-off here is the sheer volume of the shake itself. Two scoops mixed with liquid makes for a hefty drink that can feel like a meal in a glass, which some people find tough to finish. If your goal is simple, calorie-dense mass without fuss, this delivers exactly what the label promises.

At 1,280 calories and 52 grams of protein per scoop, Dymatize Super Mass Gainer is built for anyone who struggles to hit their daily surplus through food alone. That calorie count is a serious head start for hardgainers or athletes burning through energy during heavy training blocks. The blend of whey and casein means your muscles get a quick hit of protein right after your shake, plus a slower release over the next several hours, useful for recovery when you’re not eating again soon. And the added gram of creatine per serving is a nice bonus, saving you a separate scoop if you’re already taking it.

The trade-off here is the carb load: 245 grams per serving is a lot, even for a mass gainer. If you’re someone who watches carb intake or prefers a leaner bulk, this might overshoot your targets in one shake. Just keep in mind you’re getting 8 servings per container, so you’ll need to plan your purchases accordingly.

With 1,230 calories and 50 grams of protein per serving, this mass gainer packs serious nutritional density into a single shake. The formula uses just three ingredients, pea protein, organic rice protein, and organic tapioca maltodextrin, so you know exactly what you’re putting in your body. It’s NSF Certified, meaning the label matches what’s inside, and it skips artificial sweeteners, soy, gluten, and dairy entirely. For anyone following a vegan diet who wants a straightforward, clean way to add mass without mystery additives, this is the obvious choice.

The trade-off is that it comes unflavored, so you’ll need to blend in fruit, cocoa, or a splash of plant milk to make it taste like something you look forward to drinking. That also means you have full control over the final flavor, which some people actually prefer. Compared to something like Optimum Nutrition Serious Mass, which uses whey and a longer ingredient list, Naked Vegan Mass keeps things minimal and plant-based. If you want a mass gainer that’s as transparent as its name suggests and you don’t mind mixing your own shake, this delivers exactly what it promises.

Each serving delivers 770 calories from oat flour, organic tapioca maltodextrin, and sweet potato powder, giving you a calorie-dense base for a surplus. The 53 grams of grass-fed whey protein provides a complete amino acid profile to support muscle repair, while the added 3 grams of creatine monohydrate can aid strength gains directly in your shake. With no artificial sweeteners or preservatives, this is a straightforward option if you want a clean mass gainer.

The trade-off comes down to serving count: 15 servings per container means you will run through it quickly if you are bulking hard. The 110 grams of carbs per scoop might be more than you need if you prefer a lower-carb approach. Compared to the Optimum Nutrition Serious Mass option, which offers a different calorie and protein profile, Transparent Labs keeps its ingredient list simple and transparent. It is a good pick for anyone who values what goes into their shake over sheer volume.

Sixty grams of protein in each serving is the headline here, and it’s a big one for anyone trying to build mass without drinking shakes all day. Each serving delivers 650 calories and more than 80 grams of carbs, which means you’re getting a dense, efficient fuel source for recovery and growth. The sugar stays under 8 grams per serving, so you’re not just loading up on empty sweetness. This is a gainer built for people who want steady, measurable progress without the sugar crash or the need to blend three different powders together.

The trade-off is the tub itself: at over 10 pounds, it’s not something you’ll toss in a gym bag or stash under a desk. You’re committing to a big container, which makes sense if you’re consistent at home but less practical if you travel often. If you want high protein with controlled sugar and don’t mind the size, this is your pick.

With 53 grams of protein and just 6 grams of fat per serving, this product leans heavily toward lean muscle instead of excess fluff. That low-fat count means you get the calories to grow without loading up on saturated fats, which is rare in this category. The blend of fast-digesting whey concentrate and slow-release micellar casein gives you a steady stream of amino acids, supporting recovery long after your shake is finished. If you are the type who wants to add size but keeps a close eye on your macros, this formula makes that balancing act much simpler.

Compared to something like Optimum Nutrition Serious Mass, which packs more calories per scoop, NutraBio keeps the fat lower and the protein quality front and center. That makes it a better fit for someone who wants controlled bulking rather than just shoveling in calories. Just know that the vanilla flavor is your only option straight from the tub, so if variety matters, you may want to plan ahead.

A single serving packs 1,250 calories, 50 grams of protein, and 252 grams of carbs, which makes it a serious tool for anyone who finds it hard to eat enough to gain mass. The ingredient list is short: whey, casein, and organic tapioca maltodextrin, so you know exactly what you’re putting in your body. NSF certification verifies the product meets standards for quality. This is a straightforward formula that suits someone who wants maximum calories without artificial sweeteners, flavors, or colors getting in the way.

This mass gainer is unflavored, so you’ll need to blend it with milk, fruit, or a flavoring of your choice to make it palatable. That also gives you control over the final taste, which some people prefer. Compared to the Optimum Nutrition Serious Mass product, which lists whey protein, creatine, glutamine, BCAAs, and vitamins, Naked Mass keeps things simpler with just three ingredients. If you want a bare-bones, budget-friendly mass gainer that lets you customize the flavor and avoid extras, this one delivers exactly what it promises.

1,100 calories and 56 grams of protein per serving give this gainer a serious head start for anyone trying to add mass without living on a mixer. What sets it apart is the whole-food ingredient list, barley, sweet potato, rolled oats, avocado, coconut oil, flaxseed, pumpkin seed, and sunflower oil. That means you are getting calorie density from real sources, not just a sugar bomb. For someone who wants their weight gainer to feel closer to actual food, this is a refreshing change. The whey isolate, concentrate, and casein blend also delivers a steady release of amino acids, with 26.1 grams of EAAs and 12.2 grams of BCAAs to support recovery.

The Mutant Mass Extreme Gainer delivers 1,100 calories and 56 grams of protein per serving, which supports weight gain and active lifestyles. With 16 servings in a 2.2-pound pouch, you will finish it faster than larger tubs from other brands. This product is designed for someone who wants whole-food ingredients like sweet potato, rolled oats, and avocado in their shake.

With a 6:1 carb-to-protein ratio and over 1,220 calories per serving, this mass gainer is built for serious bulking. The 40 grams of all-whey protein deliver 9 grams of naturally occurring BCAAs per serving. It also includes pure creatine monohydrate. This is a straightforward, calorie-dense fuel to support hard training.

The 250-plus grams of carbohydrates per serving make it a poor fit if you’re watching your carb intake or aiming for leaner gains. The protein comes entirely from whey, which some people digest faster than blended sources. You mix two scoops with about 18 to 20 ounces of liquid. If your goal is straightforward mass and you can handle the carbs, this one earns its spot.
