Exceptional Customer Service

Product is excellent. Customer service even better. In response to a problem with my order, Brandon responded quickly & resolved it right away. Really appreciate the professionalism from this company. Some companies get it & take care of their clients. Nothing but positives to say re Transparent Labs. Thanks

I didn’t like the taste

I didn’t like the taste at all. Gets too foamy when blended.

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.
