Best overall: 5% Nutrition (Rich Piana) Real Carbs + Protein, Banana Nut Bread

The anti-sugar-bomb: a real-food meal in a tub. Whole-grain oats, sweet potato and rice for the carbs, a beef-egg-chicken-chickpea protein blend, 6 g of fiber and just 2-3 g of sugar — no maltodextrin, no dextrin derivatives, dairy-free.

What We Like
  • Genuine whole-food carbs (oats + sweet potato + rice) and only 2-3 g sugar — no maltodextrin at all
  • Dairy-free, lactose-free, whey-free animal+plant protein blend with 6 g real fiber
  • Closest thing on the list to eating a clean meal; ideal for stacking servings to taste
What You Live With
  • Only ~260 calories per scoop — you must take multiple servings to create a real surplus (not a one-shake bomb)
  • 20-serving tub is smaller; per-meal cost adds up when you scale the dose
Calories
~260 kcal per serving (1 scoop) — scale up servings to hit a surplus
Protein
21 g whole-food blend (beef, egg, chicken, chickpea)
Carbs / Sugar
30 g total / 2-3 g sugar, 6 g fiber
Carb source
Whole-food: whole-grain oats, sweet potato, brown rice
Extras
Dairy-free / lactose-free / whey-free; iron, magnesium, potassium, vitamin A

Our take — Real Carbs + Protein is the honest hardgainer's pick: instead of chasing a giant calorie headline with maltodextrin and sugar, it's a clean whole-food meal you control the size of. The carbs are actual oats, sweet potato and rice; the protein is a dairy-free beef-egg-chicken-chickpea blend; there's 6 g of fiber and only 2-3 g of sugar. At ~260 calories a scoop it isn't a one-shake bomb — you stack servings through the day to build your surplus, which is exactly how a thoughtful bulk should work. It loses the top spot only because hitting a big surplus takes several scoops and the cost mounts. For anyone who refuses to drink a sugar-bomb, it's the best clean gainer here.

  1. Optimum Nutrition Serious Mass, Chocolate, 12 lb weight gainer tub — from the Amazon listing02

    Best value (cheapest calories): Optimum Nutrition Serious Mass, Chocolate

    7.8SAC Score™

    The default best-seller and the cheapest serious calories on the list: 1,250 calories, 50 g protein, 25 vitamins and minerals and 3 g of creatine for roughly $0.06 per 100 calories. The trade-off is honest — maltodextrin carbs and around 31 g of sugar.

    What We Like
    • Cheapest calories on the list at roughly $0.38 per 100 kcal — the value benchmark
    • Trusted best-selling brand; 25 vitamins and minerals plus ~3 g creatine included
    • Reliable mixability and a flavor people actually finish
    What You Live With
    • Around 31 g of added sugar per serving — a genuine sugar load
    • Carbs are maltodextrin, not whole food; minor formula drift on vitamin/creatine counts across versions
    Carb source
    Maltodextrin (refined starch) — primary carbohydrate
    Extras
    25 vitamins & minerals, ~3 g creatine (formula version varies)

    Our take — Serious Mass is the category's default for a reason — it's the cheapest way to add real calories, at roughly six cents per 100, from a brand you can trust, with 50 g of protein, 25 vitamins and minerals and 3 g of creatine in the tub. If your only goal is maximum calories for minimum money, nothing here beats it. But it's also the picture of the category's compromise: the carbs are maltodextrin and there's about 31 g of sugar in every serving, which is exactly the sugar-bomb profile our framing warns about. Buy it if value per calorie is your top priority and you'll manage the sugar elsewhere in your diet — but know the three picks above it are cleaner fuel for the same job.

  2. Dymatize Super Mass Gainer, Gourmet Vanilla, 12 lb tub — from the Amazon listing03

    Most calories per scoop (whey blend): Dymatize Super Mass Gainer, Gourmet Vanilla

    7.6SAC Score™

    A slightly higher-calorie, higher-protein maltodextrin tub: 1,280 calories and 52 g of a whey-isolate-and-casein blend with 10.7 g of BCAAs and 1 g of creatine. Mixes well and tastes good — but it's the same maltodextrin-and-sugar template.

    What We Like
    • Highest per-scoop calories (1,280) and protein (52 g) of the mainstream tubs
    • Quality protein blend — whey concentrate, isolate and casein — with 10.7 g BCAAs
    • Strong mixability and well-liked flavors; often the cheapest per calorie here
    What You Live With
    • Maltodextrin-based carbs with ~26 g sugar — same sugar-bomb category as ON
    • Only 1 g creatine (a token dose versus the effective 3-5 g)
    Carb source
    Maltodextrin (refined starch) — primary carbohydrate
    Extras
    1 g creatine, 14 essential vitamins & minerals

    Our take — Super Mass Gainer is essentially ON Serious Mass's closest rival, and on raw numbers it edges ahead — 1,280 calories and 52 g of a genuinely good whey-isolate-and-casein blend with 10.7 g of BCAAs, and it's frequently the cheapest tub per calorie on the whole list. Mixability and flavor are strong. It sits one rung below ON only on the extras: the creatine is a token 1 g rather than an effective dose, and ON's broader vitamin panel and best-seller value edge it out. The core caveat is identical, though — the carbs are maltodextrin and there's about 26 g of sugar a serving. A fine high-calorie, high-protein tub for someone who wants maximum macros per scoop and isn't bothered by the sugar.

  3. BSN TRUE-MASS 1200, Chocolate Milkshake, 10.38 lb weight gainer tub — from the Amazon listing04

    Best protein blend: BSN TRUE-MASS 1200, Chocolate Milkshake

    7.5SAC Score™

    The sustained-release protein pick: a six-source blend (whey, casein, milk and egg proteins) for 50 g protein and 24 g EAAs, with whole oat flour cut into the carbs and a lower 16 g of sugar than the pure-maltodextrin tubs.

    What We Like
    • Six-source sustained-release protein blend (24 g EAAs) — the best protein quality among the bulk tubs
    • Whole oat flour blended into the carbs and 16 g fiber; lower 16 g sugar than the maltodextrin-only tubs
    • MCT powder included; well-regarded milkshake flavors
    What You Live With
    • Carbs are still maltodextrin-led despite the added oats; no creatine
    • Lower calories (1,230) at a higher per-calorie price than ON or Dymatize
    Carb source
    Maltodextrin + whole oat flour (partial whole-food)
    Extras
    11 g naturally occurring BCAAs, MCT powder; no added creatine

    Our take — TRUE-MASS 1200 is the connoisseur's bulk tub: instead of bargain concentrate, it uses a six-source protein blend — whey, casein, milk and egg proteins — for 50 g of sustained-release protein and 24 g of EAAs, the best protein quality in the high-calorie tier. It also nudges toward the clean side, cutting whole oat flour into the carbs, carrying 16 g of fiber and holding sugar to 16 g, noticeably below the pure-maltodextrin tubs. The reasons it lands mid-pack: the carbs are still maltodextrin-led despite the oats, there's no creatine, and at 1,230 calories it costs more per calorie than ON or Dymatize. For someone who cares most about protein quality in a gainer, it's the standout.

  4. Crazy Nutrition Mass Gainer, Chocolate, 2.5 kg tub — from the Amazon listing05

    Best lean gainer (lower calorie): Crazy Nutrition Mass Gainer, Chocolate

    7.2SAC Score™

    A moderate 'lean gainer' for adding controlled calories without a 1,200-calorie bomb: ~488 calories, 40 g protein, oat-flour-led carbs with only ~8 g sugar, plus a DigeZyme enzyme complex for easier digestion.

    What We Like
    • Oat-flour-led carbs with only ~8 g sugar — cleaner carb base than the maltodextrin bombs
    • Moderate ~488 calories suits a controlled 'lean bulk' rather than rapid mass
    • DigeZyme enzyme complex and MCTs for easier digestion; added B-vitamins, zinc, magnesium
    What You Live With
    • Most expensive per calorie of any tub here, and a premium sticker price
    • Sweetened with sucralose (artificial); no creatine; dairy-based (not vegan)
    Carb source
    Gluten-free oat flour (lead) + maltodextrin
    Extras
    DigeZyme digestive enzymes, MCT oil, B6/B12/zinc/magnesium; sucralose-sweetened

    Our take — Crazy Nutrition Mass Gainer is the 'lean gainer' of the group: at ~488 calories it's built for adding a controlled surplus rather than dumping 1,200 calories at once, and its carbs lead with gluten-free oat flour for a cleaner base and only ~8 g of sugar. The DigeZyme enzyme blend and MCTs make it sit easier than the heavy tubs. The honest reasons it ranks low: it's the priciest per calorie on the entire list, it's sweetened with artificial sucralose, and there's no creatine. If you specifically want a lighter, easier-digesting gainer for a slow lean bulk and don't mind paying for it, it has a real niche — but it's poor value as pure calories.

  5. Naked Mass unflavored natural weight gainer, 8 lb bulk tub — from the Amazon listing06

    Best low-sugar bulk calories: Naked Mass, Unflavored

    7.1SAC Score™

    The cleanest way to get a full 1,250-calorie bulk shake: just three ingredients — grass-fed whey, micellar casein and organic tapioca maltodextrin — with 50 g protein and only 5 g of sugar. No artificial anything, NSF Certified.

    • Full 1,250-calorie bulk shake with only 5 g sugar — by far the lowest sugar in the high-calorie tier
    • Three ingredients only; grass-fed whey + micellar casein blend, NSF Certified for purity
    • No artificial sweeteners, flavors or colors
    What You Live With
    • Carbs are tapioca maltodextrin — clean and unsweetened, but still a refined starch, not whole food
    • Very large ~7-scoop serving is thick; unflavored is bland; no creatine included
    Carb source
    Organic tapioca maltodextrin (gluten-free) — refined, but no added sugar
    Extras
    Just 3 ingredients; NSF Certified, GMO-free, gluten-free, soy-free; no creatine

    Our take — If you want a true 1,250-calorie bulk shake but refuse the sugar that usually comes with it, Naked Mass is the answer: three ingredients — grass-fed whey, micellar casein and organic tapioca maltodextrin — 50 g of protein, and just 5 g of sugar, with NSF certification and zero artificial additives. It's the cleanest of the genuine high-calorie tubs. The honest qualifier that keeps it at #3: the carbs are still maltodextrin — unsweetened and clean, but a refined starch rather than the whole-food oats and sweet potato the two picks above it use — and the unflavored, seven-scoop serving is thick and plain, with no creatine. For low-sugar bulk calories from a trustworthy label, it's excellent.

  6. MuscleTech Mass-Tech Extreme 2000, Triple Chocolate Brownie, 6 lb tub — from the Amazon listing07

    Most calories (with milk): MuscleTech Mass-Tech Extreme 2000, Triple Chocolate Brownie

    6.9SAC Score™

    The maximum-calorie bomb with the one genuinely useful edge: a full 5 g of creatine. But read the fine print — the headline '2,000 calories' only happens when you blend it with 20 oz of skim milk; the powder itself is ~2,060 with water and built on maltodextrin.

    What We Like
    • The genuine extra: a full 5 g of creatine monohydrate (most gainers under-dose this)
    • Enormous calorie and protein ceiling for the most extreme hardgainers (~2,060 kcal, 60 g protein from powder alone)
    • 8.4 g leucine and 20+ vitamins and minerals
    What You Live With
    • The '2,000 calorie' / 80 g protein headline requires blending with 20 oz of skim milk — the powder, not the product, supplies the rest
    • Maltodextrin-led carbs; a huge 6-scoop serving means only ~5 servings per bag (expensive per serving)
    Carb source
    Maltodextrin + oat bran + isomaltulose (maltodextrin-led)
    Extras
    5 g creatine monohydrate, 8.4 g leucine, 20+ vitamins & minerals

    Our take — Mass-Tech Extreme 2000 is the maximum-calorie option, and it has one feature the others mostly lack — a full, effective 5 g of creatine plus 8.4 g of leucine. For the rare hardgainer who genuinely struggles to eat and wants the highest possible calorie ceiling, that's a real draw. But it ranks last on honesty grounds, and we'll be plain about why: the marquee '2,000 calories' and '80 g protein' only materialize when you blend it with 20 ounces of skim milk — the powder itself is the engine, but the milk is doing real work in that headline, so it's partly selling you your own groceries. The carbs are maltodextrin-led, and the six-scoop serving means a bag is gone in about five uses. Powerful for an extreme bulk; the least clean and least honest label on the list.

    The cleanest gainer in the category: 770 calories built from whole-food carbs — oat flour, organic tapioca and sweet potato — with 53 g of grass-fed whey, 3 g creatine, zero artificial sweeteners and no added sugar. Proof a mass gainer doesn't have to be a sugar-bomb.

    What You Live With
    • Most expensive per calorie on the list — you pay a real premium for the clean formula

    Extras
    3 g creatine monohydrate, MCTs; stevia + monk fruit only

    Our take — If you've genuinely decided you need a gainer, this is the one to buy: Transparent Labs proves the whole category's sugar habit is a choice, not a necessity. Its 770 calories come from real food — oat flour, sweet potato and tapioca — alongside 53 g of grass-fed whey and 3 g of creatine, with no added sugar and not a single artificial sweetener or dye. It's the formula closest to the clean DIY shake we keep recommending, just in a convenient tub. The honest catches: it's the priciest per calorie here, and at 770 calories a serious hardgainer may need two scoops a day. But for a transparency-and-quality-first ranking, the cleanest gainer in the category is the right number one.

Buying Guide

The Guide In Four Short Lessons

RULE 1

Check that you can use the calories.

A gainer is a 700-1,250 kcal shake. Without a sustained surplus plus hard training and about 1.6 g/kg of protein, it adds fat, not muscle.

RULE 2

Read the carb quality and the sugar.

Carb ratio and carb quality carry 30% of our score, ahead of calorie and protein density.

RULE 3

Compare the cost per calorie with food.

The calories do not build muscle differently from the same calories on a plate. You are paying for convenience.

Surplus + training + protein — the honest mechanism; full scoring below.

Verdict

The bottom line

01

The default: 5% Nutrition Real Carbs + Protein (#1).

Real food in a tub: whole-grain oats, sweet potato and rice for the carbs, a beef-egg-chicken-chickpea protein blend, no junk-sugar bulk padding the calorie count. Transparent Labs (#8) lost the top spot on Sep 7, 2026: its listing shows no legible Supplement Facts photo, so its numbers cannot be verified against the label.

02

Only buy one if you genuinely can't eat enough.

It's a hard-gainer's convenience for hitting a surplus, never a shortcut around training.

03

A gainer without a surplus and training just adds fat.

That's the whole rule — the tub amplifies what you're already doing, or it amplifies nothing.

Frequently Asked

Quick Answers

Which pick is the best overall?

Real Carbs + Protein, Banana Nut Bread by 5% Nutrition (Rich Piana) is our #1 pick (SAC score 8.8/10). Real Carbs + Protein is the honest hardgainer's pick: instead of chasing a giant calorie headline with maltodextrin and sugar, it's a clean whole-food meal you control the size of. The carbs are actual oats, sweet potato and rice; the protein is a dairy-free beef-egg-chicken-chickpea blend; there's 6 g of fiber and only 2-3 g of sugar. At ~260 calories a scoop it isn't a one-shake bomb — you stack servings through the day to build your surplus, which is exactly how a thoughtful bulk should work. It loses the top spot only because hitting a big surplus takes several scoops and the cost mounts. For anyone who refuses to drink a sugar-bomb, it's the best clean gainer here.

What is the best budget option?

Optimum Nutrition Serious Mass — see its pick card above for price and details.

How much do these picks cost?

Across our ranked picks, prices run from about $45 to $90 — exact price and cost per serving are listed on every pick card above.

How were these picks ranked?

Mass gainers are easy to rank badly: line them up by calories per scoop, crown the 2,000-calorie tub and call it a day. That's exactly the mistake the category wants you to make, because the cheapest way to hit a huge calorie number is to pour in maltodextrin and sugar. So we weighted carb-to-protein ratio AND carb quality the heaviest, at 30%: a gainer built on whole-food carbs (oats, sweet potato, rice) with low added sugar beats one built on a wall of maltodextrin and 30 grams of sugar, even if the maltodextrin tub has a bigger calorie headline — because for everyone who isn't an elite endurance athlete, slower whole-food carbs and minimal sugar are simply the better fuel. Calorie and protein density comes next at 25%, judged together: enough calories to actually create a surplus (the entire point of the product), with a protein dose — ideally 40-55 g — high enough that you're building on protein, not just dumping sugar. Ingredient quality is worth 20%: the protein source (grass-fed whey and multi-source blends over bargain concentrate), useful extras like creatine, digestive enzymes and real micronutrients, and natural over artificial sweeteners and dyes. Value per calorie is 15% and it's measured honestly — cost per 100 calories, not sticker price, because a gainer's job is calories and the bulk maltodextrin tubs are genuinely cheaper per calorie than the clean ones; we credit that even as we dock them on quality. Mixability and taste round it out at 10%, because a thick 1,250-calorie shake you dread drinking is one you'll quit. Every macro was read off the product's real label; we did not invent a single calorie, sugar gram or protein figure, and where a headline depends on added milk — MuscleTech's 2,000 calories assumes 20 oz of skim milk — we judged the powder on its own, not the milk's.

Pooling 49 studies (1,863 participants), protein supplementation significantly increased resistance-training-induced gains in muscle mass and strength — but the benefit plateaued: total protein intakes above ~1.6 g/kg/day produced no further gains in fat-free mass. The basis for this page's core honesty point — a mass gainer's protein helps build muscle only up to a defined ceiling, and dumping extra calories (or sugar) past that point adds fat, not muscle.
  2. [2] Slater 2019 PMID 31482093 — Is an energy surplus required to maximize skeletal muscle hypertrophy associated with resistance training. This review concludes that while a positive energy balance (a calorie surplus) provides an anabolic environment that supports muscle hypertrophy alongside resistance training, the magnitude of surplus required is modest and individual, and a large surplus mainly adds fat rather than extra muscle. The evidence basis for treating a mass gainer as nothing more than a convenient way to add a measured surplus — useful only for those who can't reach it through food, and never a substitute for training.
