How is this different from other similar products online? Our products are tested, verified, and backed by decades of experience in the supplement and ingredient industry. We prioritize quality, consistency, and customer trust. Do you provide Certificates of Analysis (COAs)? Yes. COAs are available upon request. We believe in transparency and provide testing documentation to support product quality and safety. Why do some of your powders have ratios like 4:1 or 10:1? Those numbers show the concentration of a powder extract. A 4:1 extract uses 4 pounds of the raw plant to make 1 pound of extract. Extracts give you a more potent version of the original ingredient. The higher the ratio, the more potent the extract. What does it mean when a powder shows a percentage like 3% or 5%? This means the product is standardized to contain a consistent amount of a specific active compound. For example, 5% indicates that 5% of the powder is the active ingredient and the rest is a base to help with stability and dosing. Is there a reason to choose a standardized extract over a pure ingredient? Pure active ingredients are often too strong or unstable on their own. Standardized extracts offer a reliable, consistent, and more effective way to use them safely and accurately.
