Beef Protein Isolate


Muscle Building Calories







CARNIVOR MASS BIG STEER 1250 is more advanced than the typical mass gainer. The key to a mass building diet is to be able to consume lots of calories and sufficient protein to support muscle growth and increased mass. Where regular foods and typical gainers may be limited in terms of digestibility and speed of absorption, CARNIVOR MASS BIG STEER 1250 excels.

This advanced mass gainer combines clinically tested hydrolyzed Beef Protein Isolate (BPI) with easily digestible micronized carbs and a dual-action insulin signal amplifying technology known as iSpike. The combination of BPI, fast acting carbs and iSpike act in tandem to trigger and anabolism state to help build and repair muscle. CARNIVOR MASS BIG STEER 1250 is a fast, clean and highly anabolic gainer which is ideal for hard gainers who struggle to pack on muscle mass.

CARNIVOR MASS BIG STEER 1250 is a scientifically-developed highly anabolic mass gainer. It’s exclusive combination of clinically tested Carnivor hydrolyzed beef protein isolate, 255G of fast acting, reactive enhanced carbohydrates, insulin optimizers and whopping 1250 calories create the ideal mass building environment for serious gains!


Faster Protein, Faster Carbs and iSpike Trigger Explosive Muscle Growth

It takes more than just calories to gain muscle mass. In order to stimulate muscle growth without accumulating body fat, it takes both calories and improved nutrient partitioning to create a highly anabolic environment. This is best achieved with (1) properly timed, high-speed macronutrient delivery and (2) properly-timed insulin optimization.

1) High-Speed Macronutrient Delivery: Proteins and carbohydrates that are absorbed at high speeds can help spike your blood amino acid and glucose levels. In turn, this stimulates the potential for higher speeds of protein and glycogen synthesis (anabolism), which can result in faster gains in muscle mass.

2) Properly-Timed Insulin Optimization: Insulin is a powerful muscle growth and recovery hormone, so much so that pro bodybuilders and athletes seek to increase their natural product and proclaim amazingly fast gains. Yes, insulin is that anabolic and effectively triggers muscle growth, especially in combination with a fast acting protein.


iSpike Technology - The Key To Building Lean Mass

CARNIVOR MASS reduces the average size of the carbohydrate particles in iSpike while increasing the total number of particles. The result is a significant increase in reactive surface area, increasing the ability for faster absorption. Research suggests that iSpike’s surface area-enhanced carbohydrates, when combined with a fast-acting protein, may promote up to 500% greater insulin spike as compared to eating the protein alone.

Did you know that when you drink calories rather than chew them, you skip the important first step of carbohydrate digestion and bypass carbohydrate-digesting enzymes secreted into your saliva? This fact has been totally neglected by makers of conventional mass gainers. It can result in a delay in absorption and a shorter insulin spike. iSpike addresses this problem with a natural system of amylases to enhance carbohydrate breakdown. This encourages higher insulin spikes.


CARNIVOR MASS BIG STEER 1250 - Ideal times of use

With its clinically tested Beef Protein Isolate, micronized carbs and iSpike Technology, CARNIVOR MASS BIG STEER 1250 allows the advanced bodybuilder to benefit from high-speed macronutrient delivery, improved insulin management and enhanced anabolism in one convenient product. Most importantly, you will be able to reach your caloric and protein requirements with whopping 1250 calories, 50 g protein and 255 g carbohydrates without feeling bloated or having digestive issues. Ideal times to consume CARNIVOR MASS BIG STEER 1250 are:

- Post-workout (to speed recovery and muscle growth).
- Upon awakening in the morning (to suppress catabolism and restore anabolism).
- Any other time throughout the day when several hours have passed since your last meal.

Get bigger

Its the best mass gainer no doubts.. i swear I gained 16kg in 3 months with only 2 scopes a day. Of course the 16kg I gained was not all pure muscles maybe 50% of the weight gained was fat and maybe if u followed a different plan of training and diet u will not gain this much fat. By the end of day I was so happy with it even if gained fat at least I got bigger.. I hope u make another protein powder with less carbs and keep everything else as its especially the insulin stuff which i think is the secret ingredient that made me bigger Best wishes
