If you’re a hardgainer, we have the supplement for you. 

Struggling to meet your daily calorie intake? If you’re a hardgainer, you know the challenge isn’t losing weight—it’s gaining it. For bodybuilders and lifters looking to build mass, the obstacle often lies in consuming enough calories to fuel muscle growth. Eating large, calorie-dense meals day after day can be exhausting and repetitive. That’s where ultra-high-calorie weight gainers come in. These supplements provide the calories and nutrients needed to help you gain weight and build muscle effectively.

Typically available in shakes or pills, weight gainers offer a more convenient alternative to eating endless plates of food. Packed with macronutrients like carbohydrates and proteins, they deliver the energy and materials your body needs to build lean muscle (1).

If you aim to pack on lean muscle mass, an ultra-high-calorie weight gainer could be the solution. However, it’s crucial to choose a product with high-quality ingredients that promote muscle growth—not just an increase in the number on the scale. One standout product is MuscleMeds Carnivor Mass, a weight gainer that checks all the right boxes. Below, we’ll dive into why this supplement is a game-changer for anyone looking to build serious muscle.

Ultra-high-calorie weight gainers are supplements that are high in calories. Athletes can use them to increase their weight and build muscle mass. They contain macronutrients like proteins, carbohydrates, vitamins, minerals, and all essential nutrients. These combined help improve your performance, build your immune system, and improve your health. Below, we list the benefits of MuscleMeds Carnivor Mass as a high-calorie weight gainer.

MuscleMeds Carnivor Mass Benefits

  1. It’s a good substitute for enormous meals.
  2. Carnivor Mass provides many calories to perform rigorous tasks and improve your performance.
  3. It’s perfect for bodybuilders because they help you increase your weight and build lean muscle.

  5. They positively impact your health because they contain other essential vitamins and minerals the body needs to function correctly.   

Carnivore Mass from MuscleMeds is also known as the “anabolic superfood.” It’s the perfect mass-gainer for bodybuilders because it’s easily absorbed compared to regular foods and other mass-gainers. MuscleMeds has been a leader in sports nutrition for over fifteen years. Using the latest well-researched ingredients, its unique approach breaks the bounds of sports performance and enhancements.

MuscleMeds Carnivor Mass is an ultra-high-calorie weight gainer that provides immense calories and the proper nutrients to create the perfect anabolic environment. It promotes ultrahigh-speed macronutrient absorption, spiking glucose, and blood amino acid levels. This can stimulate protein synthesis, also known as anabolism, leading to impressive and faster gains in muscle mass.

MuscleMeds Carnivor Mass also contains Beef Protein Isolate (BPI), which combines with their iSpike (insulin signal amplifying technology) to give you adequately timed insulin optimization. This study shows that combining carbohydrates with proteins can help increase insulin levels (2). This increase in insulin plays a key role in muscle growth and recovery.

Additionally, Carnivor Mass combines the mass-building effects of meat with the speed of whey protein, which is USDA-approved. This combination is free of the side effects of cholesterol, fats, lactose, allergies, and other challenges associated with products. It also contains increased anabolic power and is 350% stronger in amino acids than meat. 

Ingredients

iSpike Technology

The iSpike tech facilitates carbohydrates in the Carnivor Mass supplement, which enhances muscle growth. These include microparticulate maltodextrin, amylase, microparticulate waxy maize, and glucoamylase. 

Insulin-Signal-Amplifying System

The insulin signal amplifying system in MuscleMeds Carnivor Mass is a network of nutrients that increases the insulin signal in different cells. These include d-pinitol, hydroxy isoleucine, chromium picolinate, and agaricus blazei.

  • D-Pinitol: Helps with inflammation, regulates insulin, and improves insulin sensitivity. It also reduces blood glucose levels in people with type-1 and type-2 diabetes.
  • 4-Hydroxyisoleucine: This compound increases glucose-induced insulin release (3). 
  • Chromium Picolinate: It combines picolinic acid and chromium to improve insulin function and help with muscle building.
  • Agaricus Blazei: It also affects insulin levels and is used to treat diabetes.

Carnivor Mass BI Blend

The MuscleMeD Carnivor Mass BI Blend includes l-glutamine, hydrolyzed beef protein isolate, creatine monohydrate, BCAAs (l-valine, l-leucine, and l-isoleucine), Anabolic Nitrogen Retention Technology Intermediates (GKG.OKG, KIC. AKG), acesulfame, potassium, silicone, hydrolyzed beef gelatin, MCTs, sucralose, cocoa, salt, gum blend, partially defatted peanut flour, antifoam, natural and artificial flavors. 

  • L-glutamine: A protein-building block that benefits the immune system and gut health. It also helps with recovery by decreasing muscle soreness after intense training (4).
  • Hydrolyzed Beef Protein Isolate: This highly absorbable protein source can help muscle growth and recovery. It’s high in essential amino acids and low in carbohydrates and fats. This lactose-free ingredient contains collagen and gelatin, suitable for joint health and skin elasticity.
  • Creatine Monohydrate: This increases and improves muscle performance. It also helps muscles recover quickly, especially after intense exercises. 
  • BCAAs: These include l-valine, l-leucine, and l-isoleucine. They help regulate protein metabolism and build muscle.
  • Hydrolyzed Beef Gelatin: Hydrolyzed beef gelatin contains several amino acids and is a high source of protein. It promotes an increase in muscle mass while also supporting joint health, digestion, and bone health.
  • MCTs: A type of saturated fat used to treat various conditions and food absorption irregularities, such as liver disease and diarrhea.

*Note: MuscleMeds Carnivor Mass also contains peanuts.

Pricing

MuscleMeds Carnivor Mass comes in a 6-lb container (2674g) with 720 calories of 50g hydrolyzed beef protein isolate, 125g carbs, and low fat. You get all these benefits for just $62.00. The 6 lbs container gives you 14 servings and comes in five distinct flavors:

  • Strawberry
  • Chocolate Fudge
  • Chocolate Peanut Butter
  • Vanilla Caramel

How to Take MuscleMeds Carnivor Mass

Pour 16 oz. (450 ml) of water into a bottle, container, or blender. Then, add four scoops of MuscleMeds Carnivor Mass. Blend or mix until the shake reaches your preferred texture before drinking. If you want a thicker shake, add less water; if you want a thinner shake, add more water. MuscleMeds says this shake can be taken at any time of the day.
