    50g protein  (yellow pea protein, organic brown rice protein)
    248g carbohydrates
    4g fat
  • Type: Powder
  • Ingredients: Organic Tapioca Maltodextrin, Pea Protein, Rice Protein
  • Number of servings: 14
  • Size: 8 LBS (3.63KG)
✅ Massive amount of calories, protein, and carbohydrates❌ Rather-limited flavor choices- Chocolate and Vanilla flavors have more than 50g of sugar per serving
✅ Supplies all 9 Essential Amino Acids
✅ Specifically tailored for vegans 

If you are looking for serious, lactose-free mass-gaining nutrition, Vegan Naked Mass is up for the job. 

Looking at the numbers, this vegan weight gainer looks more than ready to boost your daily caloric intake. Each serving supplies your body with a whopping 1230 calories – roughly the same amount you get with most dairy-based mass gainer supplements.

Vegan Naked Mass also packs a lot of protein per serving, giving you 50g of plant-based protein in each serving. This is quite impressive for a dairy-free mass gainer. It features a combination of yellow pea protein and brown rice protein, giving you all 9 Essential Amino Acids that are needed for lean muscle growth and recovery.

Vegan Naked Mass contains 252g of carbohydrates per serving. It uses organic maltodextrin, a complex carbohydrate that is absorbed in a slower rate. This makes Vegan Naked Mass a good mass gainer to take before bedtime or for those moments when you won’t be able to eat a full meal for a couple of hours.

The Chocolate and Vanilla variants have 52g and 54g of sugar (organic tapioca maltodextrin) per serving. If you are trying to minimize your sugar intake, you might want to go for the Unflavored version, which only has 24g of sugar per serving. 

On its label, it says that you need 4 scoops to fix up 1 serving. There are some users, however, who say that you need more than just 4 scoops to get all 1230 calories in place.


On paper, Vegan Naked Mass looks well-built to support muscle growth and lean gains for vegans and lactose-intolerant people. With 1230 calories, 50g of protein, and 252g of complex carbohydrates per serving, this plant-based weight gain shake is no push-over. Just be mindful of its rather high sugar content for the Chocolate and Vanilla versions.


MuscleMeds Carnivor Mass
  • Nutrition per serving:
    710 calories
    50g protein  (hydrolyzed beef protein isolate)
    125g carbohydrates
    2g fat
  • Type: Powder
  • Number of servings: 25
✅ Great source of muscle-building protein❌ Some users report it to be too frothy or hard to mix
✅ Contains creatine monohydrate and Medium Chain Triglycerides
✅ Zero sugar
✅ Uses quick-digesting carbs for fast nutrient delivery
✅ Available in 4 flavors (Chocolate Fudge, Chocolate Peanut Butter, Strawberry, Vanilla Caramel)

If you are on the lookout for a mass gainer that can also support exercise performance, Carnivor Mass by MuscleMeds can help.

Each serving of Carnivor Mass delivers a decent 720 calories per serving – and it does so without loading up your body with too much fat or sugar. It is marketed to have zero sugar content, which sounds good if you are trying to watch your sugar intake. Each serving has 3g of fat, which is also a bit lower than what most mass gainers have (around 4g to 7g).

Unlike typical mass gainers that rely on dairy for their protein content, Carnivor Mass uses hydrolyzed beef protein isolate. Just like whey protein, beef protein isolate supplies your body with all the Essential Amino Acids required for building and repairing lean muscle tissue. Each serving delivers 50g of beef protein isolate, which is impressive for a weight gain shake.

Carnivor Mass bets on High-Speed Macronutrient Delivery and Properly-Timed Insulin Optimization for speeding up protein and glycogen synthesis. Each serving has 125g of carbohydrates in the form of microparticulated maltodextrin and microparticulated waxy maize. These are supposed to be quickly absorbed and digested by the body, making way for faster muscle gains.

Carnivor Mass takes it a step further by adding 5g of creatine monohydrate to its formula. Creatine monohydrate may help buffer the buildup of lactic acid while you work out, allowing you to complete more reps and lift heavier weights for longer periods. Creatine also drives more water to your muscle cells, making your muscles appear larger and more volumized.

The serving size requires 4 scoops added to 16 fl.oz of water. Some users report having issues with the shake being too frothy or lumpy, so it might be a good idea to mix the powder with warm water first to achieve a smoother consistency.


While it does not look to provide the most calories per serving, Carnivor Mass looks to be a good mass gainer choice for people who have digestive issues with lactose and dairy. Its blend of hydrolyzed beef protein and quick-absorbing carbs sounds like a good combo for building mass – not to mention that it includes 5g of creatine monohydrate to help you maximize your workout performance.
