Consider it. The best protein blend in the bulk tier — six sources, 24 g EAAs — with real oat flour and lower sugar, but maltodextrin-led carbs, no creatine and a higher price per calorie. A six-source protein blend (whey, casein, milk and egg) delivers 50 g protein and 24 g EAAs in a 1,230-calorie shake, with whole oat flour blended into the carbs, 16 g fiber and just 16 g sugar — cleaner than the pure-maltodextrin tubs.

Why It Scores 7.5 — And The Label Line Behind Each Number
Carb ratio & carb quality
30% of scoreThe best carb profile of the high-calorie tubs, though still not whole-food-led. It cuts whole oat flour into the carbohydrate, carries 16 g of fiber and holds sugar to 16 g — noticeably cleaner than the ~26-31 g of the pure-maltodextrin tubs. But the base is still maltodextrin-led despite the oats, which caps it below the whole-food and low-sugar picks above.
Calorie & protein density
25% of scoreSolid — 1,230 calories and 50 g of protein per serving, with the protein squarely in the ideal window. It's a genuine bulk dose, though slightly lower in calories than Dymatize (1,280) and ON (1,250), which is why it scores a notch below them on raw density even as it beats them on protein quality.
- Protein
- 50 g, six-source blend (whey, casein, milk & egg proteins) — 24 g EAAs
Ingredient quality
20% of scoreThe protein is the best in the tier — a six-source blend of whey, casein, milk and egg proteins with 24 g of EAAs and 11 g of naturally occurring BCAAs, plus MCT powder and 16 g of fiber. What holds it to a mid score: the carbs are still maltodextrin-led, and there's no creatine. Great protein, incomplete formula.
Value per calorie
15% of scoreThe weakest axis. At roughly $0.35 per 100 kcal, with fewer calories per serving, it costs more per calorie than ON or Dymatize. You're paying for the superior protein blend and the cleaner carb profile, but on the pure cost-per-calorie metric it's mid-pack, not a value leader.
- Servings
- 15 per 10.38 lb tub
- Price
- $65 / tub ≈ $4.33 per serving ($0.35 / 100 kcal)
Mixability & taste
10% of scoreThe strongest axis and the best mixability score in the bulk tier. The Chocolate Milkshake flavor is well regarded, and the multi-source protein plus MCT powder give it a smoother, more milkshake-like texture than the grainier maltodextrin tubs — a real compliance advantage for a heavy daily shake.

Marketing Claims Vs. Reality
A six-source protein blend delivering 50 g protein and 24 g EAAs.
The label lists a blend of whey, casein, milk and egg proteins totaling 50 g with 24 g of EAAs, verifiable from the panel. It is a genuinely higher-quality, multi-source protein matrix than the concentrate-led rivals, and the figures hold up.
Sustained-release protein.
The blend does include slower-digesting fractions (casein and milk protein) alongside faster whey, which supports a slower, more prolonged amino-acid release, so the descriptor has a real basis. But 'sustained-release' is a marketing framing rather than a measured, guaranteed-timing property, so treat it as directionally accurate, not a precise claim.
Lower sugar with real oat flour in the carbs.
The 16 g of sugar and inclusion of whole oat flour plus 16 g of fiber are label-stated and verifiably lower/cleaner than the ~26-31 g of sugar in the pure-maltodextrin tubs. The oat flour is genuine, though the carb base remains maltodextrin-led.
A premium clean-carb bulk gainer.
The carbs are cleaner than the other bulk tubs — real oats, more fiber, less sugar — but the base is still maltodextrin-led, so 'clean-carb' overstates it. Accurate as 'the cleanest of the maltodextrin tubs,' not as a whole-food carb source like the top two picks.
Supports muscle mass and recovery.
The high-quality protein and 24 g of EAAs genuinely support muscle protein synthesis (Moore 2009, PMID 19056590), but muscle growth still requires a sustained surplus plus resistance training (Slater 2019, PMID 31482093). The recovery/mass claim is well-supported on the protein side, conditional on training and surplus overall.
What Our Test Actually Found
The best protein you can get in a bulk tub
Most gainers cut costs on protein with bargain concentrate. True-Mass 1200 goes the other way with a six-source blend — whey, casein, milk and egg proteins — for 50 g of protein and 24 g of EAAs, plus a slower-digesting profile from the casein and milk fractions. If protein quality is what you care about most in a gainer, this is the standout of the whole list's high-calorie tier.
The cleanest carbs of the maltodextrin tubs — but still maltodextrin-led
It's a genuine step toward clean: whole oat flour cut into the carbohydrate, 16 g of fiber, and sugar held to 16 g — noticeably below the ~26-31 g of ON and Dymatize. The honest limit is that the base is still maltodextrin-led despite the oats, so it's the cleanest of the refined-carb tubs rather than a whole-food formula like the top two picks.
No creatine and pricier per calorie — the two real gaps
The reasons it sits mid-pack rather than higher: there's no creatine (add 3-5 g separately per Kreider 2017), and at roughly $0.35 per 100 kcal with fewer calories per serving it costs more than ON or Dymatize. You're paying for the protein blend and cleaner carbs, not for cheap calories.
It drinks like a milkshake — real compliance advantage
The multi-source protein and added MCT powder give it a smoother, more milkshake-like texture than the grainier maltodextrin tubs, and the Chocolate Milkshake flavor is well regarded. For a heavy 1,230-calorie shake you have to drink daily, being genuinely pleasant to consume matters more than the numbers suggest.

Quick Answers
What makes the protein blend better than ON or Dymatize?
It uses six protein sources — whey, casein, milk and egg proteins — rather than a concentrate-led blend, giving 24 g of EAAs and a slower, more sustained amino-acid release from the casein and milk fractions. For protein quality specifically, it's the best in the high-calorie tier. Whether that's worth the higher price per calorie depends on how much you weight protein quality versus cheap calories.
Is it actually lower in sugar?
Yes — 16 g per serving, versus ~26 g in Dymatize and ~31 g in ON, plus it cuts real oat flour into the carbs and carries 16 g of fiber. It's the cleanest of the maltodextrin-based bulk tubs. It still isn't a whole-food carb source like the top two picks, since the base remains maltodextrin-led, but it's a genuine step cleaner than its direct rivals.
Does it have creatine?
No. If you want creatine, add 3-5 g of monohydrate separately — the effective dose per the ISSN position stand (Kreider 2017). Given that True-Mass already costs more per calorie than the value tubs, factor a cheap creatine tub into the total if creatine matters to you.
Why is it ranked below the cheaper ON and Dymatize?
The ranking weights carb quality (30%) and calorie/protein density (25%) most heavily, and on density True-Mass has slightly fewer calories while costing more per calorie, which drags its value axis down. Its superior protein blend and lower sugar earn it the 'best protein blend' badge, but the price-per-calorie gap and missing creatine keep it a half-step behind on the overall score.

- [1] Moore 2009 PMID 19056590 — Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men. Muscle protein synthesis was near-maximally stimulated around 20 g of high-quality protein per serving. True-Mass's 50 g multi-source blend with 24 g EAAs comfortably clears that per-serving threshold with high-quality protein.
- [2] Morton 2018 PMID 28698222 — A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. Protein supplementation aids gains up to ~1.6 g/kg/day. The 50 g high-quality dose sits in the useful window; the value of this tub is that its protein — not sugar — carries much of the formula.
- [3] Schoenfeld 2018 PMID 29497353 — How much protein can the body use in a single meal for muscle-building? Implications for daily protein distribution. The authors recommend ~0.4 g/kg per meal for optimal muscle protein synthesis. The 50 g dose here covers a per-meal protein target for most users, and the slower casein fraction extends amino-acid delivery.
- [4] Slater 2019 PMID 31482093 — Is an energy surplus required to maximize skeletal muscle hypertrophy associated with resistance training. A modest surplus supports hypertrophy; a large one mainly adds fat. This 1,230 kcal shake supplies a single-serving surplus — the protein blend and lower sugar make it a cleaner way to hit it than the pure-maltodextrin tubs.
