SAC StudioA 1,250-calorie bulk shake listed at only 5 g of sugar and three ingredients, per the listing — the cleanest-looking of the high-calorie tubs, on numbers we could not verify from a legible panel.
Naked Mass is, on paper, the answer for anyone who wants a genuine 1,250-calorie bulk shake but refuses the 25-35 g of sugar that usually comes with it. The listing's entire formula is three ingredients — grass-fed whey, micellar casein and organic tapioca maltodextrin — delivering 50 g of protein and just 5 g of sugar, the lowest in the high-calorie tier by a wide margin, with no artificial sweeteners, flavors or colors. It's the cleanest-looking of the true bulk tubs on its stated numbers.
The honest qualifiers keeping it at #3 rather than higher: the carbs are still tapioca maltodextrin — unsweetened and clean per the listing, but a refined starch rather than the whole-food oats and sweet potato the two picks above use — the unflavored, roughly seven-scoop serving is thick and plain, with no creatine included, and we could not verify any of these figures against a legible Supplement Facts photo in this listing's gallery — see the label check below. For low-sugar bulk calories on numbers you're trusting from the listing rather than a confirmed panel, it is still a strong pick.
A genuinely mixed result, and the headline number here is unverified. The listing claims only 5 g of sugar in a 1,250-calorie shake — by far the lowest in the high-calorie tier if accurate — but we could not confirm that figure against a legible Supplement Facts panel; no photo in this listing's gallery shows one clearly. The carbohydrate itself is listed as organic tapioca maltodextrin: unsweetened and gluten-free per the listing, yet still a refined, high-glycemic starch rather than the whole-food oats and sweet potato of the two picks above. Credit for the listing's low-sugar claim, held down for the unverified panel and the refined carb source.
A true bulk tub on paper — the listing states 1,250 kcal and 50 g of protein in a single serving, squarely in the ideal 40-55 g protein window and enough calories to create a real surplus in one shake. We could not verify these figures against a legible Supplement Facts panel, so we're crediting the listing's numbers rather than a confirmed label read. It also scores below the leaders because those calories come mostly from refined maltodextrin rather than a denser, higher-quality carbohydrate mix.
Per the listing: three ingredients, NSF-tested for contents, GMO-free, gluten-free and soy-free, with grass-fed whey plus micellar casein and no artificial sweeteners, flavors or colors. We could not verify the ingredient list, the NSF claim or the allergen-free claims against a legible Supplement Facts or certification photo in this listing's gallery, so this is credited as stated rather than confirmed — a meaningful mark down from a directly verified label. The other marks against: 'grass-fed' is a manufacturer sourcing claim, and there's no creatine or added micronutrient panel.
At roughly $0.51 per 100 kcal — using the listing's stated 1,250 kcal, which we could not verify against a legible panel — it's mid-pack: cheaper per calorie than the clean whole-food picks above it, but more expensive than the bulk maltodextrin tubs like ON and Dymatize. You're paying a modest premium over the cheapest calories for the three-ingredient, listing-claimed low-sugar formula, which is a fair trade if those numbers hold up.
The weakest axis. A ~7-scoop, 1,250-calorie serving is genuinely thick, and the unflavored version is bland — you'll likely blend it with fruit or add your own flavoring. It mixes acceptably but the sheer serving size and lack of flavor make it harder to drink daily than a moderate-calorie shake.
“Only 5 g of sugar in a 1,250-calorie shake.”
The listing claims 5 g of sugar per 1,250-calorie serving — by far the lowest sugar in the high-calorie tier if accurate, a fraction of the ~31 g in ON Serious Mass at the same calorie count. This is the product's headline advantage, but we could not verify it against a legible Supplement Facts panel; no photo in this listing's gallery shows one clearly.
“Just three ingredients.”
The listing states the formula is grass-fed whey, micellar casein and organic tapioca maltodextrin — three ingredients, no fillers, flavors or dyes. We could not verify this against a legible Supplement Facts or ingredients photo in this listing's gallery, so we're crediting it as stated rather than confirmed.
“Clean carbs / natural weight gainer.”
The carb source is listed as organic tapioca maltodextrin — unsweetened, gluten-free and free of added sugar per the listing, so 'clean' is fair on the sugar and additive front if the listing is accurate; we could not verify these figures against a legible Supplement Facts panel. But maltodextrin is still a refined, high-glycemic starch, not a whole food, so 'clean' should be read as low-sugar-and-minimally-formulated rather than whole-food carbohydrate.
“NSF-tested / independently third-party tested.”
Naked Nutrition's marketing states independent third-party testing and NSF involvement for contents. We could not verify a certificate or a legible panel photo in this listing's gallery, so we're crediting the brand's claim as stated rather than confirmed. Note this is contents/quality testing, not the athlete-focused 'NSF Certified for Sport' banned-substance tier — a meaningful distinction for tested competitors, so the claim should be read as a brand assertion, not sport certification.
“Grass-fed whey and micellar casein.”
The whey-and-casein blend and 50 g protein dose are stated on the listing, but we could not verify them against a legible Supplement Facts panel — no photo in this listing's gallery shows one clearly. 'Grass-fed' is a manufacturer sourcing claim rather than an independently certified one, so treat the protein amount and blend as listing-stated, not confirmed, and the grass-fed sourcing as a brand assertion.
We checked all 17 gallery images for this ASIN (Sep 7, 2026) and none show a flat, legible Supplement Facts panel — the closest is a partial, angled nutrition-panel shot that doesn't resolve to readable text. We can confirm the product is Naked Nutrition's Naked Mass (Unflavored), sold as an 8 lb / 11-serving tub. We cannot confirm the calorie, protein, sugar, carb or BCAA figures, the three-ingredient claim, the NSF-testing claim, or the grass-fed/micellar-casein sourcing directly from a label photo — every number and claim below is reported as what the listing states, not as a verified label read. We've lowered the criteria that credited label transparency and dose disclosure accordingly, and will re-score if a legible panel photo becomes available.
The whole trick of a bulk gainer is packing 1,250 calories into a shake, and the cheap way to do that is maltodextrin plus a wall of sugar. Naked Mass's listing states it hits the same 1,250 calories with only 5 g of sugar — a fraction of the ~31 g in ON Serious Mass at the identical calorie count. We could not verify that 5 g figure against a legible Supplement Facts panel, but if the listing is accurate, this is the cleanest way to get a genuine single-shake surplus without the sugar-bomb.
This is why it sits at #3 rather than #1. The carbohydrate is listed as organic tapioca maltodextrin: unsweetened, gluten-free and additive-free per the listing, but still a fast, refined starch rather than the whole-food oats and sweet potato in the two picks above. It's a much cleaner maltodextrin than the sugar-laden tubs on paper, but it isn't whole food, and the ranking rewards whole-food carbs.
Grass-fed whey, micellar casein, organic tapioca maltodextrin. That's the entire formula as stated — no artificial sweeteners, flavors or colors, NSF-tested for contents, GMO-free and soy-free. We could not verify this list against a legible Supplement Facts or ingredients photo in this listing's gallery. For anyone who wants to know exactly what they're drinking, the short listing is the selling point, and it's rare in a bulk tub — just note it's unverified rather than confirmed.
The honest downsides: a ~7-scoop, 1,250-calorie serving (per the listing) is genuinely thick, the unflavored version is plain enough that most people blend it with fruit, and there's no creatine in the listed formula (add 3-5 g of monohydrate separately per Kreider 2017). None of that is a dealbreaker, but budget for a blender, some fruit and a separate creatine tub.
If you specifically need a true 1,250-calorie single shake — the kind of surplus the moderate-calorie picks above can't deliver in one serving — but you refuse the 25-35 g of sugar that usually rides along, Naked Mass is the answer on paper. Three ingredients, 50 g of protein, and only 5 g of sugar per the listing, with NSF testing claimed and no artificial anything. Among the bulk tubs, nothing looks cleaner on its stated numbers. It lands at #3 for three honest reasons. First, the carbohydrate is still tapioca maltodextrin — a much cleaner, unsweetened maltodextrin than the sugar-laden tubs on paper, but a refined starch rather than the whole-food oats and sweet potato that the two picks above it use, and this ranking rewards whole food. Second, the seven-scoop serving is thick, the unflavored version is bland, and there's no creatine. Third, and the reason we've marked it 'consider' rather than 'buy': none of the 17 gallery images for this listing show a legible Supplement Facts panel, so the calorie, protein, sugar and certification figures above are the listing's claims, not a confirmed label read. Buy it if your priority is low-sugar bulk calories and you're comfortable trusting those listing numbers — and blend it with fruit and add your own creatine.

The best-overall pick — whole-food carbs, 53 g whey and 3 g creatine, no added sugar. Choose it if you want whole-food carbohydrate and built-in creatine rather than clean maltodextrin.
See it on the list →The same 1,250 kcal and 50 g protein for cheaper per calorie, plus 25 vitamins and 3 g creatine — but with ~31 g of sugar. The pick if value beats sugar for you.
See it on the list →A 1,230-calorie tub with a superior six-source protein blend and some whole oat flour, at 16 g sugar. Choose it if protein quality matters more than absolute-lowest sugar.
See it on the list →A modest energy surplus supports hypertrophy alongside training, while a large surplus mainly adds fat. A 1,250 kcal shake is a big single-serving surplus, so use it to top up a diet you can't otherwise get calories into — not to overshoot.
Protein supplementation aids resistance-training gains up to ~1.6 g/kg/day. The 50 g dose sits in the useful range; the value of this tub is that most of its calories aren't wasted sugar past that ceiling.
The authors suggest ~0.4 g/kg per meal to optimize muscle protein synthesis. The whey-plus-casein blend here supplies 50 g in one serving, comfortably covering a per-meal target, with casein adding a slower-digesting fraction.
