Arnold Schwarzenegger teamed up with MusclePharmŪ scientists and together they created a revolutionary weight gainer. In order to stimulate rapid muscle growth (and do this without spurring fat development) it takes both calories and precise nutrient partitioning to create the muscle building environment an athlete needs. As a whole new kind of all-in-one Mass Gainer, this supplement addresses every angle of muscle building. It utilizes a 5-stage Mass Delivery System, comprised of advanced protein technology, elite complex carbs, healthy fats, cutting-edge performance ingredients and a balanced digestive blend—plus it's low in sugar and tastes delicious!*

Iron Mass™ includes the cutting-edge Muscle Plasma Protein Technology. This potent combination of hydrolyzed beef protein and lactoferrin protein contains more bioactive protein and peptides with MORE THAN THREE TIMES the growth factor levels of whey protein. Its blend of EFA's (healthy fats), MCT's and saturated fats are essential for the body's hormone production. By increasing your healthy fat intake, you support testosterone production, which creates more lean muscle and, ultimately, gains in strength.*

The elite carbohydrate performance and glycogen-loading system delivers high-energy complex carbs. Working with the advanced fat blend, it allows for quicker recovery and muscle building while also ensuring your glycogen levels don't spill out into body fat. This Elite blend of complex carbs also helps "pull" water into muscles to support fullness, pump and hardness to give your muscles that round, substantial, skin splitting look. Our performance blend of creatine and BCAA nitrates assists with promoting muscular strength, size, and endurance. Lastly, our special dietary fiber blend aids with the digestion of the added protein, carbs and fat needed for getting big—and staying big!*

Supplement Facts

As a dietary supplement for supporting explosive muscle growth and recovery, mix one serving (2 scoops) of Iron Mass™ with 12-16 fl. oz. of cold water. Consume 1 to 3 times a day. Vary the amount of water to achieve your desired consistency and taste. To increase your protein intake per serving and achieve a delicious milkshake taste, instead of water use skim or low fat milk, or almond milk.

Our protein supplement guide will help you excel on the court, in the gym, or on the road
If you take your workouts seriously, nutrition should be top of mind too. Protein is a great place to start, and focusing on getting the right types of protein, in the right amounts, and at the right times is key. Our protein supplement guide will help you meet your wellness goals, potentially improving your performance on the court, in the gym, or on the road.

What type?


Whey protein is quick to digest and provides all of the protein building blocks - the amino acids. Our bodies cannot make some amino acids, and whey is ideal for meeting essential amino acid needs. Whey also supplies branched-chain amino acids (BCAA), and some research supports that they aid muscle recovery after hard workouts.


Compared with whey, casein is slower to digest, and results in a lower, yet more prolonged rise in blood amino acid levels, which may provide a particular advantage for body builders. At least one study supports that casein outshines whey in terms of promoting strength and lean body mass gains in people following a structured weight-training plan.


Rice protein is less likely to create allergic reactions than other proteins, and it comes from a plant, making it appropriate for vegetarians. Another potential advantage is that rice protein contains a high proportion of arginine, an amino acid that can dilate blood vessels, possibly enhancing blood flow to muscles. Rice is not a "complete" protein however; it doesn't supply all of the essential amino acids. Some products combine rice protein with proteins from sources like soy or milk to make it complete.


Egg protein is ideal for people who are looking to build new muscle. It has a very high protein efficiency ratio (PER), which is one measure of how well our bodies can use any particular form of protein. The higher the PER, the more efficiently our bodies can use that protein when we eat it. Egg is off the charts in terms of PER. Egg protein also is a complete protein, and is a good source of essential and branched chain amino acids. Egg protein powder is made from egg whites, and comes in a convenient, pasteurized powder form.


Soy protein is a high-quality plant protein that provides all essential amino acids, making it a good option for vegetarians. For the body to best utilize soy protein, vegetarians should also eat grain or dairy within a few days. Soy protein comes in two basic forms: soy protein isolate and soy protein concentrate. Soy protein isolate is the most highly purified form, and has a minimum protein content of 90%. Soy protein concentrate contains more carbohydrates, and has a protein content of approximately 70%. Concentrates tend to cost a little less, but if you find soy protein concentrate doesn't agree with you, try isolate, which is easier for some people to digest.

How much?

With protein, as with many nutrients, more is not always better. According to Dr. Doug Paddon-Jones, Associate Professor at the University of Texas Medical Branch and Director of Exercise Studies, "30 grams of protein appears to stimulate maximum muscle synthesis. For athletes, each meal and snack is a chance to hit the 30 gram mark, giving your body several opportunities each day to maximize muscle growth and repair."

Another reason to spread protein evenly through the day is simple efficiency. "Given that your body won't use much beyond 30 grams of protein at a time, it doesn't make sense to load up with more than this," says Paddon-Jones.


  • Breakfast-To support muscle building first thing in the morning, try trading traditional carb-heavy breakfast foods for more protein-rich options, such as a powder protein supplement mixed with milk and cereal.
  • If you're heading into a long strength-training session-Sipping a casein-based protein supplement prior to and during your workout will give muscles sustained access to amino acids. If taken in the evening, casein can provide a steady supply of amino acids while you're sleeping.
  • Immediately pre- or post-workout-Especially if your workout includes aerobic or circuit training, protein manufacturers recommend a whey protein-based liquid or powder supplement.

Comments about MusclePharm® Arnold Schwarzenegger™ Series IRON MASS™ - Chocolate Malt:

I purchased this product because I wanted to gain a specific nominal amount of lean mass without excessive fat (I started out at 4.2% Body fat composition and after 8 weeks ended up at roughly 5% and yes, I understand that this can fluctuate with the time of day, accuracy/validity of testing protocol, etc.). I should also state that I am 5'9" and started out at approximately 154 lbs. when I started using this product. At the end of my 8 weeks, I ended up at 161 lbs.

As part of my goal for 8 weeks, my daily nutrient intake was very clean (vegetables, lean meats, sweet potatoes, poly & mono fats from nuts/seeds/flax seed, small portions of fruit, dark leafy greens, and around 1.75 gallons of water. I used this product mainly to supplement my daily intake due to caloric deficits (because of a very clean intake and cost effectiveness) and to aide with increasing lean muscle mass. My workouts were an accurate reflection of my goals as I lifted for power & strength over an 8 week period.

I used this product daily, in fact, most days 2X's daily. I mixed this product with a combination of unsweetened almond milk, unsweetened coconut milk, and water. The product does not mix well even in only water! However, if you can get past this, the taste was more than satisfying!

In conclusion, this product definitely assisted me in achieving my very specific 8 week goals (gain lean muscle mass without excess fat). First and foremost, find out what your SPECIFIC goals are when looking at mass gainers or any sport & fitness supplement. If your goals are centered around gaining lean mass without excess fat, and you do so in a very specific, very clean way, then this product can assist you!

I also might add to those of you looking at the ingredients and seeing a higher number of grams of fat per serving than most other comparable products, keep in mind that in order to gain lean mass, a good amount of fat is necessary to obtain the results you seek (fat, cholesterol, testosterone = higher anabolic state which in turn, = >lean muscle mass)!
