Certificate of Analysis & Lot Testing

Independent Testing

Every product lot is independently analyzed by a third-party laboratory accredited to ISO/IEC 17025. Optimized Performance Inc. does not perform its own release testing — verification is external so the analytical record is independent of the supplier.

What Each Lot Is Tested For

• Identity & purity — confirmation of the reference compound and percent purity.
• Quantity / content — verification of stated content per vial.
• Sterility (USP 71) and endotoxin screening, where applicable to the format.
• Heavy metals.
• Vial-to-vial variance characterization across the lot.

Oral-solution and small-molecule reference materials are tested under the analytical panel appropriate to their format (identity, purity, content, and microbial/residual-solvent screening as applicable).

Accessing a Certificate of Analysis

Each vial label carries a lot number and a scannable QR code. Scanning the code — or visiting /coa/{sku}/{lot} — resolves to the lot-specific Certificate of Analysis for that exact production lot. Product pages also link to the current lot's Certificate of Analysis.

If a lot's full certificate is still in process, the page indicates that preliminary results are pending and the final certificate will be posted on receipt.

What a Certificate Shows

Each certificate identifies the product, the lot number, the testing laboratory, the analytical methods used, and the measured results for the panel above. Certificates are provided for analytical reference and documentation purposes.
