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).
- Delicious Chocolate and Vanilla Flavors: Choose from two decadent flavors—Chocolate Glaze Donut and Sweet Vanilla.
- No Artificial Sweeteners, Fillers, or Colors: You won't find any "funny business" with the ingredients we use. Instead of the usual laundry list of artificial additives, Transparent Labs Mass Gainer is naturally-flavored and sweetened with stevia; plus, there are no added sugars.
- Third-Party Tested and Certified for Quality: As part of our commitment to industry-leading transparency and quality, every batch of this product is tested by a third-party lab for purity and potency. You can find all of our test results in the footer of our website. This product is also certified by Informed Choice to meet the highest standards for athletes and consumers.

A.
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.
A.
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.
A.
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).
A.
Generally, mass gainer supplements are well-tolerated, but digestive discomfort and bloating may occur in some instances, depending on your overall diet, gastrointestinal integrity, and inherent ingredient tolerances. We strongly recommend starting with a half-serving of Transparent Labs Mass Gainer for the first week so you can better assess how it affects your body.
A.
Yes, it contains coconut and milk-based ingredients. Do not consume if you have an allergy to tree nuts or dairy.

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. |
Is it OK to 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 Mass Gainer Help Me Build Muscle Mass Even if I Don't Workout? | 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? | Generally, mass gainer supplements are well-tolerated, but digestive discomfort and bloating may occur in some instances, depending on your overall diet, gastrointestinal integrity, and inherent ingredient tolerances. We strongly recommend starting with a half-serving of Transparent Labs Mass Gainer for the first week so you can better assess how it affects your body. |
Does Transparent Labs Mass Gainer Contain Nuts? | Yes, it contains coconut and milk-based ingredients. Do not consume if you have an allergy to tree nuts or dairy. |
Does Transparent Labs Ship to My Country? | Transparent Labs offers worldwide shipping, with a few exceptions due to import restrictions in the EU/UK, and high fraudulent activity in specific countries. Please check our shipping policy for more details. |
When Will My Order Be Shipped Out? | All orders are dispatched the following business day. |
Grass-fed Whey Protein Concentrate | Protein, especially complete protein (i.e. a protein source that provides all nine essential amino acids), is paramount for muscle protein synthesis, which ultimately contributes to muscle growth. Unlike many mass gainers that use low-quality protein sources, Transparent Labs Mass Gainer features grass-fed whey protein concentrate, a clean, easy-to-digest, complete protein well-known to bolster muscle growth [1]. |
Healthy Fats (from MCT Oil and Coconut Milk) | Not all fat is "bad"; in fact, some fats are quite healthy and necessary (especially for weight gain). We've upped the ante by including an ample dose of medium-chain triglycerides (MCTs) from MCT oil and coconut milk. MCTs are a special class of saturated fatty acids that are quickly absorbed and provide unique health benefits, such as increasing high-density lipoprotein (HDL) cholesterol (aka the "good" cholesterol) and fighting inflammation [2]. |
Organic Tapioca Maltodextrin, Oat Flour, and Sweet Potato Powder | The carbohydrates in our weight-gain formula come from real food sources, including organic tapioca, oat flour, and sweet potato. This blend provides a balanced, easy-to-digest supply of fast-acting, long-lasting energy and replenishes muscle glycogen after workouts. |
Tapioca Fiber and VitaFiber® | Fiber intake is essential for maintaining gut health and supporting digestion, especially with a high-protein diet. The prebiotic fiber sources in Transparent Labs Mass Gainer, like VitaFiber®, feed the "friendly" microbes in your gastrointestinal tract, helping them grow and proliferate so you can better digest nutrients and stay “regular”. |
Creatine Monohydrate | Creatine monohydrate has stood the test of time, and then some. It is the most proven athletic supplement, with decades of scientific evidence demonstrating its positive impacts on muscle-building, recovery, and athletic performance [3, 4]. |
