The Verdict
Naked Mass edges Transparent Labs on our rubric, 87 to 84 on our 0-100 execution score, and in our view it is the pick when a clean deck is the priority: it is NSF Certified, uses organic tapioca maltodextrin rather than standard maltodextrin, and delivers 1,250 calories with only 5g of sugar. Transparent Labs is answering a different question. Its 770 calorie serving with oat flour and sweet potato carbohydrates plus the 3g creatine monohydrate dose suits a moderate lean bulk better, and it outscores Naked on our value pillar (21 vs 18) and our transparency pillar (24 vs 23).
The trade-off we see is certification depth: Naked carries NSF Certification, while Transparent Labs' third-party testing runs through its own internal program with published COAs rather than NSF or Informed Sport. In our view, take Naked Mass for the cleanest label and the bigger calorie load, and Transparent Labs if you want a meal-shaped macro split with creatine included.

Why This Comparison Matters
Naked Mass and Transparent Labs Mass Gainer are the two highest-scoring products in our mass gainer review, and they answer the same goal in very different ways. Naked Mass is a three-ingredient, 1,250 calorie powder built on grass-fed whey concentrate, micellar casein, and organic tapioca maltodextrin. Transparent Labs runs the lean-gainer format instead: 770 calories per scoop, carbohydrates from oat flour and sweet potato, and a full 3g dose of creatine monohydrate already in the tub.
The number that decides most of this matchup is cost per calorie rather than cost per scoop. Our data puts Naked Mass at roughly $0.51 per 100 calories ($6.36 per serving) and Transparent Labs at roughly $0.43 per 100 calories ($3.33 per serving), so the two are closer than the sticker prices suggest once you normalize for what you are actually buying.
We scored both on the same four-factor rubric: dosing and form, purity verification, value, and label transparency. Here is where each one earns and loses points.
Detailed Score Breakdown
Naked Mass
Naked Nutrition
1,250 calories per 4-scoop serving with 50g protein (grass-fed whey concentrate + micellar casein) and 252g carbohydrate from organic tapioca maltodextrin; only 5g sugar - notable for the category
NSF Certified - rare in the mass gainer category; no artificial sweeteners, flavors, or colors; soy-free and gluten-free; no rBGH/rBST; the cleanest ingredient deck in this comparison
Roughly $0.51 per 100 kcal at the current $69.99 Buy Box for the 8 lb size ($6.36/serving) - meaningfully more expensive than commodity mass gainers; the certification and clean-label sourcing justify the premium for users who want them
Three-ingredient label (organic tapioca maltodextrin, whey protein, casein protein) - effectively no proprietary blends; full macro disclosure; among the most transparent products in any supplement category
The cleanest formula in the category by a clear margin: NSF Certified, organic tapioca maltodextrin instead of standard maltodextrin/dextrose, no artificial sweeteners or flavors, no creatine or vitamin window dressing. Also the only product here that delivers a 1,250 kcal serving with just 5g of added sugar. The right pick for anyone who wants the clean-label version of this category.
Mass Gainer
Transparent Labs
760-770 calories per serving with 53g grass-fed whey concentrate, 109g carbohydrate from oat flour, organic tapioca, and sweet potato, plus 12g fat and 3g creatine monohydrate - a closer-to-meal-shaped macro split for lean bulking
Third-party tested with COAs published; not currently NSF or Informed Sport certified despite the brand's transparency emphasis; grass-fed sourcing on the whey
Roughly $0.43 per 100 kcal at the current $49.99 Buy Box ($3.33/serving) - a -29% drop that may be promotional, putting it mid-pack per calorie despite the whole-food carbohydrate sources, grass-fed whey, and included clinical creatine dose
Full label disclosure, every ingredient quantified, no proprietary blends; the brand publishes ingredient sourcing detail beyond what most competitors offer
The 'lean gainer' format: roughly half the calories of a typical mass gainer, with carbohydrates from oat flour and sweet potato instead of pure maltodextrin, and a real 3g creatine monohydrate dose. Best for moderate hardgainers who want a meal-replacement-shaped macro profile rather than a 1,250 kcal liquid bomb. Drops a tier on quality because the third-party testing is internal rather than NSF or Informed Sport.
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.

Frequently Asked Questions
Which mass gainer has more calories per serving, Naked Mass or Transparent Labs?
Naked Mass delivers 1,250 calories per 4-scoop serving (50g protein, 252g carbohydrate, 5g sugar, 2g fat). Transparent Labs Mass Gainer delivers roughly 770 calories per single scoop (53g protein, 109g carbohydrate, 12g fat, 6g sugar). Naked is the higher-calorie option per serving; Transparent Labs delivers slightly more protein in a much smaller calorie envelope.
Does either mass gainer carry a third-party certification?
Naked Mass is NSF Certified, which is uncommon in this category. Transparent Labs states its product is third-party tested through its own internal program with COAs published, but it is not currently NSF Certified or Informed Sport certified. If you compete in a tested sport, that distinction is the one worth weighing.
Is Naked Mass worth the higher price?
That depends on whether the clean-label features matter to you. In our view the premium buys three things: NSF Certification, organic tapioca maltodextrin instead of standard maltodextrin or dextrose, and only 5g of sugar inside a 1,250 calorie serving. On pure cost per calorie our data has Naked at about $0.51 per 100 calories against Transparent Labs at about $0.43, so the gap is real but modest.
