Cheapest Mass Gainer for Hard Gainers (2026)
If you cannot eat enough food to gain weight, a mass gainer is the tool. The problem is most mass gainers are absurdly expensive when you do the math by calorie. A 7lb tub of a name-brand mass gainer can run $60-80 for what is essentially whey protein, maltodextrin, and oat flour. You can buy the same calories from oats and milk for half the price; you are paying for portability.
This guide ranks every mass gainer in our live catalog by cost per 1000 calories (the only honest benchmark for a high-calorie product) and by Value Score. We also explain when a mass gainer beats whole food, and the cheap DIY recipe that beats every commercial gainer on price. Pricing is from US retailers as of mid-May 2026 and subject to change.
Quick answer: Nutricost Mass Gainer 6lb at $34.99 on Amazon is the cheapest mass gainer in 2026, with about 11,000 calories per tub ($3.18 per 1000 calories). MuscleTech Mass-Tech Extreme 7lb at $44.99 is the value pick if you want a name brand. Naked Mass 8lb at $79.99 is the premium clean-label option (just oat flour, whey, casein) at roughly $4.84 per 1000 calories.
How We Rank Mass Gainers
Three metrics matter for a mass gainer, in this order:
- Cost per 1000 calories. This is the only honest benchmark for a calorie-delivery product. A cheap product per scoop can still be expensive per calorie if the scoops are small.
- Protein-to-calorie ratio. A mass gainer should deliver at least 20g of protein per 500 calories. Below that, you are basically buying flavored carbohydrates with a sprinkle of protein.
- Ingredient quality. Look for actual carb sources (oat flour, sweet potato, maltodextrin) rather than mystery "carbohydrate blends" that turn out to be 90% dextrose and corn syrup solids.
Value Score on ProteinPrice combines these factors with retailer reliability and third-party testing data. Above 25 is good for the mass gainer category, where prices are inherently high.
The Best Value Mass Gainers in 2026
| # | Product | Best Price | $/1000 cal | Protein/serving | Score |
|---|---|---|---|---|---|
| 1 | Nutricost Mass Gainer 6lb | $34.99 (Amazon) | $3.18 | 60g | 30 |
| 2 | MuscleTech Mass-Tech Extreme 7lb | $44.99 (Amazon) | $3.21 | 63g | 23 |
| 3 | BSN True Mass 1200 5.82lb | $54.99 (Walmart) | $4.58 | 50g | 16 |
| 4 | Naked Mass 8lb (Chocolate) | $79.99 (Amazon) | $4.84 | 50g | 18 |
| 5 | Naked Mass 8lb (Vanilla) | $89.99 (Amazon) | $5.46 | 50g | 28 |
1. Nutricost Mass Gainer (Best Value Overall)
The cheap-mass-gainer floor. Nutricost applies the same no-frills budget formula to mass gainers that has made their whey and casein lines value champions. The 6lb tub at $34.99 delivers about 11,000 calories total, putting it at the lowest cost per calorie of any name-brand mass gainer we track. The chocolate flavor is acceptable, mixability is what you would expect from a high-carb product (thick, slow to dissolve in cold milk), and the protein-to-calorie ratio is solid at 60g per ~700 cal.
If you are a true hard gainer trying to push 4000+ calories per day, this is the lowest-friction way to get there. Two half-scoops add 700 calories per day at $1.16 in cost. That is hard to beat with food unless you have free access to leftover restaurant rice.
2. MuscleTech Mass-Tech Extreme 2000 (Best Name Brand)
The middle-tier pick. MuscleTech's Mass-Tech Extreme runs roughly $0.03 more per 1000 calories than Nutricost but adds a wider retailer footprint (you can grab it at GNC the same day if you run out) and slightly better flavor consistency. Each 227g scoop hits about 1000 calories with 63g of protein, which is enough to functionally replace a small meal.
The catch: the "Extreme 2000" branding refers to two scoops at 2000 calories per serving, which is too much for almost anyone to drink in one sitting. Treat it as a 1000-cal product and you get 14 servings per tub, exactly $3.21 per 1000 calories.
3. BSN True Mass 1200 (Best Premium Taste)
The taste pick. BSN True Mass has had a cult flavor reputation since 2008. Vanilla Ice Cream and Chocolate Milkshake both drink like dessert protein, which matters because hard gainers often run into flavor fatigue when they have to drink shakes daily for months. You will pay about 45% more per calorie than Nutricost, but if it keeps you actually drinking the shakes, the math works.
4. Naked Mass (Premium Clean Label)
For lifters who do not want maltodextrin and artificial sweeteners, Naked Mass is one of the few clean-label mass gainers on the market. The ingredient panel is short: organic oat flour, organic maltodextrin, grass-fed whey, casein. No flavoring, no sweeteners, no fillers. You pay a 50% premium per calorie over the cheap tier in exchange for that clarity.
The DIY Mass Gainer That Beats Every Commercial Tub
If you are price-sensitive, the math on mass gainers gets ugly fast. Here is the recipe that has been a hard-gainer staple for two decades:
The Classic Hard-Gainer Shake (~1050 cal, 50g protein)
1 cup whole milk (150 cal) + 1 scoop whey concentrate, e.g. Nutricost 25g protein (130 cal) + 1 cup rolled oats (300 cal) + 2 tbsp peanut butter (200 cal) + 1 banana (110 cal) + 1 tbsp honey (60 cal) + ice. Blend.
Cost breakdown at Walmart prices: oats $0.20, milk $0.40, peanut butter $0.40, banana $0.25, honey $0.10, whey scoop $0.50. Total per shake: $1.85. That is $1.76 per 1000 calories, beating every commercial mass gainer in our catalog by 40%+ and with a vastly better micronutrient profile.
For a base whey scoop, see the rankings in our cheapest whey 2026 guide or browse the whey protein hub. The cheap concentrate tier is exactly what you want for this recipe; you do not need isolate.
When to Buy a Commercial Mass Gainer Anyway
Despite the DIY math, commercial mass gainers still make sense in three situations:
- Travel. You can dump a scoop into a shaker bottle in a hotel room. Blending oats is not happening at a Marriott.
- Recovery from illness or surgery. When eating volume is the limiter, commercial gainers are easier than DIY shakes because you don't have to blend.
- Time-constrained life chapters. Parents of newborns, residents working 16-hour shifts, college students between classes. The 90 seconds it takes to scoop, shake, and drink matters when minutes are scarce.
If you fit any of those, picking Nutricost or MuscleTech is rational. If you don't, the DIY shake is the right answer.

FAQ
What is a mass gainer and how is it different from regular protein?
A mass gainer is a high-calorie protein powder formulated to deliver 600-1200 calories per serving, compared to 100-150 calories from regular whey. The calorie boost comes from added carbohydrates (usually maltodextrin or oats), with protein still hitting 30-60g per serving. The goal is making it physically easier to eat a calorie surplus without cooking three extra meals a day.
How much cheaper is a mass gainer than buying protein and carbs separately?
Usually about the same, sometimes worse. A pound of oats at Walmart costs $1.50 and delivers 1600 calories. Nutricost Mass Gainer at $34.99 for 6lb delivers 11,000 calories, which works out to about $3.17 per 1000 calories. Oats and whey together hit about $2.50 per 1000 calories. Mass gainers win on convenience, not on raw price.
Is a mass gainer better than just eating more food?
For most people, no. Real food has more micronutrients, more fiber, and a better satiety profile. Mass gainers exist for people who genuinely cannot eat enough food, typically classic hard gainers, athletes in high-volume training cycles, or recovery patients trying to regain lost weight. If you can fit the calories from food, do that first.
What is the cheapest mass gainer in 2026?
Nutricost Mass Gainer 6lb at $34.99 on Amazon is the cheapest by total dollars, delivering about 11,000 calories for $35. Per 1000 calories that is $3.18, the lowest in our catalog. MuscleTech Mass-Tech Extreme 7lb at $44.99 is a close second per calorie.
How many calories should a mass gainer have per serving?
Most mass gainers run 600-1300 calories per scoop. For a hard gainer adding 500 calories to baseline, a single scoop is usually too much in one sitting. A half-scoop twice a day works better for digestion and consistency. The goal is sustainable surplus, not maximum calories per shake.
Should I add anything to a mass gainer shake?
Yes, usually. Adding a banana, two tablespoons of peanut butter and a cup of whole milk to a half-scoop of mass gainer takes a 500-calorie shake to roughly 1000 calories with better satiety, more potassium and the addition of real fats. This is also how you stretch a tub: half-scoop with added food doubles your servings.
