International Protein

The renowned brand, International Protein, boasts an impressive range of sports supplements that have earned them a place as a local Australian success story. The brand was founded by Christine Envall, a professional bodybuilder, and her partner Troy, who is a food scientist.

International Protein's supplement range is built on a solid foundation of nutritional science, ensuring it delivers the best results for bodybuilding and sports performance. At the core of their offerings is the original protein supplement, Synergy5, known for its multi-release and high-purity protein formula, which was hailed as the best available in its time.

Over time, the International Protein range has expanded significantly, introducing a variety of top-notch products to meet the diverse needs of athletes and fitness enthusiasts. These include the high-calorie weight gainer, Extreme Mass, the premium Superior Whey, the energy-boosting Extreme Carbs, the muscle-building WPI, and the fat-burning protein, Iso-Cuts.

For athletes and fitness enthusiasts seeking high-quality protein and optimal sports supplements at the best prices, International Protein stands as a reliable choice, backed by their commitment to scientific excellence and performance-driven formulations.
