Ignite Anabolism: Faster Protein, Faster Carbs and iSpike Promote Explosive Muscle Growth!*

It takes more than just calories to gain muscle mass. In order to stimulate rapid muscle growth (and not fat) it takes both calories and precise nutrient partitioning to create a highly anabolic environment.


CARNIVOR MASS is the epitome of an anabolic support supplement and is more advanced than any typical mass gainer.* Where regular foods and typical gainers are limited in terms of speed of absorption, CARNIVOR MASS excels. It combines a unique best-of-breed hydrolyzed beef protein isolate (BPI) with iSpike™. BPI and iSpike act in tandem to support maximum muscle anabolism while helping minimize fat storage.* CARNIVOR MASS is an extremely fast, clean and highly anabolic gainer.* Welcome to a new era in mass building supplementation with CARNIVOR MASS, the fast, clean, highly anabolic mass gainer!*

Beef Protein Isolate – Backed By Research To Build Muscle! Beef has proven itself as a favorite anabolic protein source for many athletes and champion bodybuilders. Now MuscleMeds is the first to provide bodybuilders with a highly advanced weight gainer supplement containing the CARNIVOR Beef Protein Isolate (BPI). The use of BPI in CARNIVOR MASS provides spikes in blood amino acid levels at speeds comparable to whey, providing fast muscle building action.* In addition, the anabolic actions of CARNIVOR Beef Protein Isolate are backed by science!

MuscleMeds advanced hydrolyzed CARNIVOR Beef Protein Isolate provides the power of beef at the speed of whey, delivering rapid absorption of high concentrations of amino acids without the lactose, allergens, fat, cholesterol and other problems associated with dairy products.* This pure beef protein isolate is also 350% more concentrated in amino acids than steak and more concentrated than whey. Plus CARNIVOR MASS is enhanced with 5 grams of creatine and additional BCAAs for even greater anabolic power!*


With its Beef Protein Isolate and iSpike Technology, CARNIVOR MASS allows the advanced bodybuilder to achieve high-speed macronutrient delivery in one convenient product.* CARNIVOR MASS is ideal for consumption:

  • Post-workout (to maximize recovery and muscle growth).*
  • Upon awakening in the morning (to suppress catabolism and promote anabolism).*
  • Any other time when several hours have passed since your last meal.

It’s hard to find mass protein without having sugar in it. This product has 0 sugar with is really good. I see people complaining about the taste I see it tastes fine we don’t need sugar to like it taste perfect. The taste is totally acceptable.

Alright. So I've read a lot of comments. Mostly positive. Some users wrote that they have IBS (Irritable Bowel Syndrome) and they have no problem at all with this product. Others wrote that after drinking it they need to frequently visit the toilet. I guess some people are sensitive to specific ingredients. I never ever tried a mass gainer in my life. Been training for 7 years (ye, only now I thought it's time to get a little bigger) and I thought I'd give this a try due to no dairy, no sugar. I have IBD (Inflammatory Bowel Disease) which is much worse than IBS. I have NO issues with this at all and I got a very sensitive gut. I am drinking this for 2 weeks now, gained 4 pounds in the first week. Clearly Muscle. Ordered Vanilla Caramel, it tastes great! My first thought was cappuccino. Although a full serving in 16 oz water was too creamy so I do half servings and it's just right for me. This weight gainer was the missing chain for me. Otherwise, I eat a very healthy & clean diet. Some people might ask why I just don't eat more. Well, I can't! It's just too much food! This I can manage though, saves a ton of time too. I also don't feel bloated after drinking it even if it's after a regular meal. I could probably think of more reasons why this is great but I'll end it here. 10/10 for me in all aspects. Good luck to you all.

I've bought this product 2 times and it has been one of the best choices. The flavour is obviously very different from any whey protein, for me it isnt that bad, is just that everyone is used to the same taste from whey. The first time i bought it, i went around 10 pounds in about 2 months, following a good diet and good excercise. 2nd time, went up about 10 pounds again but in less time since i divide the serving (4 scoops) into 2 shakes with 2 scoops (half serving) each. I add some milk, oats and almods too boost up the calories taken and it has been working great for me since ive always had trouble gaining weight.

Have you ever ate *** before? Well that’s what it taste like. I ordered this product for the first time, tasted it and spilled all that was in my blender down the drain. It taste like ****, and it says mix 4 scoops in 16oz of water, and drink 1-2 times daily. It’s hard to drink because it’ so thick and taste awful. I didn’t even get a chance to see if it works, so I wouldn’t be able to tell you guys if it works or not. That’s my opinion about this product, taste nasty. Others might like it but I don’t. I even tried vanilla caramel and taste nasty to me also.

I was initially deciding between this and vegetable protein (allergic to whey) and after trying both, this by far blew out vegetable protein especially considering this is also a mass gainer. The flavor is the closest I’ve ever had to chocolate milk and am able to drink a serving very easily even if I have just eaten. I feel no bloating at all and i will continue to use this product!

It's not made from real meat. This product is made from other parts of the cow like the ears, skin,anus and whatever else. You're not getting what you think your getting.

I love the product I really must say two scoops 10 ounces of water is all I need after my work out another two scoops in 10 ounces of water when I mix shake well then I refrigerate because of my schedule I mix both bottles two scoops in each I shake very well I enjoy my shakes gives me plenty of energy and I work like a beast in the gym I’m over 55 years old and I see great changes I recommend to shake chocolate when you let it set it gives it a chance to go ahead and dissolved which gives the ultimate taste

A little chalky taste with water but still not bad. Good with milk as well. DO NOT take on an empty stomach. The product itself was great! I took it for almost two months and after a month I started to see results in which my weight today is slightly lower than 2 months ago but my body looks bigger.

This gainer has been helpful to me when used in moderation with whole foods and controlled sodium. It is high in iodized salt and vitamin b12 which is best to avoid with other supplements that promote focus. This mix taste very different than whey and personally, I think it is good tasting. My use of it is not for mass gaines and more business stamina. This product has replaced caffine and stimulates your drive in a similar way. "Dont share it at work". Continue defeating.

This supplement honestly works. I have used this in the past and saw results but I lost those gains. I have a hard time gaining weight and do not like the taste of any protein shake except this one. I am currently using this again and after a cycle of using it, I have gained about 5 pounds which was my goal. This is honestly the only shake I drink because the taste is so tolerable that you do not even know it is a protein shake. Directions: I personally do not take the recommended dose at once. I split it up in to 2 scoops with 8 oz of water twice a day.
