About
What it is.
Mass Gainer sits in Transparent Labs' sports nutrition lineup as a high-calorie powder built around grass-fed whey concentrate rather than a generic protein-carb blend. Each scoop combines a substantial protein dose with a large helping of carbohydrate and a moderate amount of fat, positioning it as a meal-replacement option as much as a post-workout shake. Flavors like Sweet Vanilla, Chocolate Glaze Donut, and Chocolate Peanut Butter cover the powder form, mixed into milk or water.
It's built for people who struggle to eat enough through whole food alone and need a dense, mixable supplement to close that gap. The formula favors named, traceable ingredients over filler carbohydrate sources, aligning with buyers who care about sourcing transparency as much as raw calorie counts, and who want something that dissolves cleanly rather than clumping in a shaker.
The verdict
Transparent Labs Mass Gainer earns strong buyer approval for its clean ingredients and smooth mixability, though its premium $80 price point raises questions about long-term value for cost-conscious users. The limited flavor selection and digestibility edge appeal to those prioritizing ingredient quality over convenience.

AI summary of 5 reviews · as of Aug 2026
Reviewers see a clean, well-labeled mass gainer with quality carb and protein sources, though some question its carb formulation and high calorie load per serving.
What they praise
- Clean ingredient list with no artificial sweeteners, colors, or added sugar
- Includes creatine monohydrate as a bonus addition
- Uses whole-food-adjacent carb sources like oat flour and sweet potato powder alongside maltodextrin
- Mixes smoothly and tastes pleasant across flavors
- Detailed, transparent labeling down to individual ingredient weights
What they knock
- Calorie load per full serving is very high, which can be too much for intermediate or advanced lifters
- Primary carb source is still maltodextrin, a cheap filler carbohydrate, despite smaller amounts of whole-food carbs
- Low in overall micronutrients compared to some other mass gainers
- Whey concentrate source lacks clarity on protein yield percentage

Who reviewers think this product is — and isn’t — for
For you if
Look elsewhere if
You need a proven, low-risk mass gainer with broad buyer consensus.
94 reviews with 4.6/5 rating shows strong consensus; Transparent Labs is an established, mature brand with a settled product track record.
You demand top-tier ingredient quality and transparent sourcing in your supplements.
High buyer trust (4.6/5, 94 reviews), best-in-class on ingredient quality & transparency, taste, and digestibility; weak flavor variety is a minor compromise.
You want a mass gainer that mixes easily and works straight out of the bag.
High marks for taste & mixability signal a straightforward, no-fuss product; whey-based formula is a proven, simple category standard.
You prefer established, prestige supplement brands with flagship positioning.
Transparent Labs is a recognized brand with strong reputation, but mass gainers are inherently utilitarian; lacks the luxury positioning of true premium connoisseur picks.
You seek supplements that delight beyond specs—great taste, feel, or design.
While taste & mixability rate high, the product is fundamentally utilitarian; no signals of passionate following or sensory/aesthetic distinction. Consider Naked Mass.
You want solid protein gains without overspending on premium branding.
At ~$80, it's mid-to-high priced for mass gainers; cheaper rivals like Real Gains (~$29) or Super Mass Gainer (~$40–60) deliver comparable basics at lower cost. Consider Real Gains.
