Worst tasting protein powder I’ve ever had. Don’t buy it. Straight up vomit flavor. Don’t waste your money.

Maltodextrin Like the Rest

The primary ingredient in this is maltodextrin, which is really bad for your gut.

Ironically, this brand does a great job at selling itself as a healthy product yet they are not using quality ingredients as they claim, otherwise, the primary ingredient would not be maltodextrin

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.
