Is Stack made with pharmaceutical-grade ingredients?

Stack is thoughtfully formulated using pharmaceutical-grade ingredients to offer you an exceptional level of purity and quality. Pharmaceutical grade ingredients must meet or exceed the standards set by pharmacopoeias (like the USP - United States Pharmacopeia or EP - European Pharmacopeia). While many supplements on the market are made with food-grade ingredients, we've taken an extra step to ensure that every dose meets the highest pharmaceutical standards. Each ingredient undergoes thorough testing for consistency and effectiveness, so you can feel confident that you're making a choice designed for optimal safety and performance.
