Arnold Iron Mass is an elite muscle-building and weight-gain supplement designed to fuel serious mass gains while maintaining lean muscle. Developed in partnership with bodybuilding icon Arnold Schwarzenegger, this scientifically formulated product includes a unique 5-stage protein blend, performance fats (including MCTs), and complex carbohydrates for sustained energy and muscle support.

Unlike traditional gainers that are overloaded with simple sugars, Iron Mass uses a smarter nutrient profile to promote clean gains without excessive fat storage. It’s ideal for athletes, bodybuilders, or hard gainers looking to boost their calorie intake while focusing on quality muscle development and recovery.

Key benefits include:

• Supports lean mass & strength

• Enhances muscle recovery

• Balanced macronutrients for clean bulking

• Backed by the Arnold Schwarzenegger Series
