Oinge Pep utilizes Krause Analytical LLC for independent analytical testing. Their testing services follow the expectations of the ISO/IEC 17025 standard, helping provide objective evaluation through laboratory-based analytical methods.
Understanding Certificates of Analysis.
A Certificate of Analysis, commonly called a COA, provides laboratory documentation tied to a specific product batch. Depending on the product and testing performed, a COA may include:
- Batch or lot number
- Product identification
- Analytical purity
- Testing method
- Date of analysis
- Laboratory information
Quality should be verified, not assumed.
Rather than relying solely on manufacturer-provided information, Oinge Pep uses independent analytical testing as an additional layer of review. We believe researchers deserve access to clear information, honest communication, and documentation that supports informed purchasing decisions.
