We source the highest quality amino acids and similar products from pharmaceutical grade production facilities in China as do all leading supplement companies including Optimum Nutrition. To be honest, there are very few amino acid producers outside of China and their product quality and claims do not stack up when researched thoroughly. We only deal with credible and reliable international suppliers with who we have developed a great working relationship with over time. We regularly test our amino acid products to ensure their purity and quality.
