ISO 100 is simply muscle-building fuel. If your goal is gaining muscle size and strength, then ISO 100 is your perfect workout partner. Loaded with muscle-building amino acids, ISO100 can support even the most serious resistance training programs. The protein in ISO100 is a combination of hydrolyzed and whey protein isolates, without any fillers or added supplements. The hydrolyzed whey protein isolate has been partially broken down into smaller proteins and peptides, ensuring rapid and easy digestion for optimal absorption of muscle-building amino acids. ISO 100 is formulated using cross-flow microfiltration, multi-step purification process that preserves important muscle-building protein fractions while removing excess carbohydrates, fat, lactose and cholesterol.
