Mass Gainer

10% off

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.

As advertised

This stuff is a game changer. Great taste, I went with vanilla first and now I've just ordered a second one in Chocolate, pumped to try it.

At first, the serving size seemed outrageous, but I followed the directions and did half the serving size (1 scoop) for the first week, then transitioned to 2 scoops daily.

I've found it best to drink one scoop immediately after workout, then second scoop 1-2 hours after lunch. Very good stuff slowly putting on pounds!

Tastes delicious & finally gaining weight

I was on the milk chocolate protein powder frm TL before which I loved but I didn’t gain any weight. Then I came across this product & read the reviews. Few women left a review that they were underweight & that this helped them gaining weight . I lost almost 20 pds in past 4 years due to PLDS and even with eating 5 meals per day, I didn’t gain weight. Now I am 3 weeks on the mass gainer and gained 2 1/2 kgs!!! I was nervous that I won’t tolerate it as I hv many food sensitivities ( no gluten / no preservatives / no artificial sweeteners). H/e, I am happy to share that this is the best stuff ever! I tolerate it well and I absolutely looove the taste.
I hv daily 2 almond milk shakes ( am/pm) from one serving. Per shake 8 oz almond milk, 1 scoop mass gainer & 1/2 banana . Using a blender. It is absolutely delicious. I do isometric exercises for muscle build up ( TL send a great article on this. Thank you! ) and starting to get a very toned body. My only regret is that I didn’t come across this product few years back .

Great product!

This is a great product, however it does need more calories so it will lasts longer.

Great but..

Love the product and will continue to use it along with other Transparent Labs products. Just wish the shipping was a bit quicker. Still a 5 Star product

Taste good & adds calories

Best tasting mass gainer I've tried so far. I do 1 scoop mid morning and another mid afternoon rather than one thick sludgy drink. I use milk and water, sometimes add heavy creamer for a few more calories. I have a ridiculously high metabolism so all that plus three meals a day is what it takes for me to put a little bit of weight on.

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.
A.
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.
