What Transparent Labs says
Overview Transparent Labs Mass Gainer formula offers whole food-based, muscle-building nutrients in a delicious, easily digestible powder form—perfect as a meal replacement shake and for post-workout recovery during a bulking phase. Unlike many weight-gainer powders, we prioritize high-quality, natural ingredients to help you gain serious mass while supporting overall health and longevity. Key Features: Quality Source of Muscle-Building Protein : Eating plenty of protein is key to building muscle, and each serving of Transparent Labs Mass Gainer provides 50+ grams of rapidly digesting protein from Grass-Fed Whey Protein Concentrate. Easy Calorie Boost : No more excuses for falling short of your calorie-intake goal; Transparent Labs Mass Gainer packs 750 calories per serving to help you achieve your weight-gain goals and pack on lean muscle mass. Added Creatine Monohydrate: If you had to pick one supplement to take for reaping the most benefits of weight training, it's tough to do better than creatine monohydrate. This is why we included 3 grams of pure creatine monohydrate in each serving of Transparent Labs Mass Gainer. Clean Carbs and Healthy Fats : With over 100 grams of slow- and fast-digesting carbohydrates from wholesome sources like non-GMO tapioca maltodextrin, sweet potato flour, and VitaFiber®, plus 14 grams of healthy fats (medium-chain triglycerides) per serving, Transparent Labs Mass Gainer is the ultimate muscle-building "meal in a shaker cup" (especially for individuals who struggle to eat enough for muscle growth throughout the day).

Frequently Asked Questions (from the seller's page)
Is a Mass Gainer the same as a protein powder? No. While mass gainers contain protein, they are not the same as protein powders. A protein powder typically contains just protein (with small/trace amounts of fat and carbs), whereas a weight (mass) gainer is formulated with protein plus carbs and fats; hence, weight gainers have considerably more calories than protein powders, and are better suited for muscle-building and weight gain. Can I use a mass gainer every day? Yes, you can use Transparent Labs Mass Gainer daily. However, it's important to use it as a supplement to other calorie-contributing foods and not as your primary source of nutrients. Will a mass gainer help me build muscle even if I don’t work out? No. Your muscles need a stimulus for hypertrophy to occur, and resistance training is the best (natural) way to provide that stimulus. Nutrients, especially protein, help your muscles rebuild after you've "damaged" them from exercise. If you remove exercise from the equation but continue eating a surplus of calories, you will gain mostly body fat (which may be beneficial and necessary if you're severely underweight). Are there side effects of taking a mass gainer? Mass-gainer supplements are typically well-tolerated, but digestive discomfort and bloating may sometimes occur, depending on your overall diet, gastrointestinal integrity, and inherent ingredient tolerances.
