With the new Arnold Iron Mass, advertisers say, you can “become your legacy.”

Part of the new Arnold Schwarzenegger product line from MusclePharm, Arnold Iron Mass is a “revolutionary all-in-one” weight gainer promoting dense muscle gain. It is said to contain a “blend of healthy fats, complex carbohydrates & BCAA nitrates.”

While every bodybuilder most likely wants to look like Arnold, let’s see if this product delivers results.

How Much Does It Cost?

According to the MusclePharm website, its products are available in over 10,000 U.S. retail outlets and more than 100 online channels globally, including,, and

Iron Mass currently retails for $50 for 5 pounds. This is in line with similar products.

What’s Inside Arnold Iron Mass?

A single-scoop serving of Arnold Iron Mass contains 95 g, of which 71.5 g comprises a proprietary blend. A few of the potent ingredients are discussed below:

Creatine Monohydrate. Creatine amplifies the effects of resistance training to enhance strength. It also improves the quality and benefits of intense speed training. During loading stages, a typical creatine dosage is 20-25 g/d. [1]

Sweet Potato Powder. Considered “among the most nutritious foods in the vegetable kingdom,” sweet potato is packed with calcium, potassium, and vitamins A and C. [2]

Branched-Chain Amino Acids (BCAAs). Multiple studies indicate BCAAs alleviate fatigue, increase fat oxidation, and improve aerobic exercise. To achieve this, a dosage of 20 g/d is recommended. [3]

Barley Starch. Barley starch contains a high amount of fiber, which lowers cholesterol and blood pressure. By slowing stomach emptying, barley keeps you feeling full, reducing appetite. A dosage of 3-12 g is a sufficient amount for inducing these effects. [4]

Hydrolyzed Beef Protein. Also known as gelatin, hydrolyzed beef protein contains collagen, which treats arthritis and joint conditions. But, there’s insufficient evidence gelatin strengthens bones/joints or reduces recovery time after exercise and sports-related injury. [5]

Final Word

While a relatively new product, Arnold Iron Mass pulls its weight.

The ingredients appear to be potent enough to fulfill promises and don’t seem to pose any health threat. This makes Arnold Iron Mass a reasonable choice for improved muscle gain.
