Manufacturer supply-chain test
These results come from an independent third-party laboratory that tested a sample of the manufacturing lot during supply-chain distribution, before GPC labelling. GPC matches the report to this catalog fill and lot and publishes a summary of what the laboratory reported: the laboratory, the report date and the analytical results.
The original third-party COA is issued to the manufacturer that submitted the sample, so GPC does not republish the document, batch and report identifiers. GPC always encourages our research customers to conduct their own third-party testing. Refer to the GPC Verification Program for more details on how GPC can help cover some of the testing fees involved.
- Source of the Data
- These values are transcribed from the certificate for the production batch behind this GPC lot. The manufacturer commissioned the analysis; GPC did not. Testing for this lot was conducted by Horizon Analytical.
- What the Results Cover
- The tested sample from this production batch at the time of analysis. They are not a direct test of every vial after shipping, storage or handling. Match the lot number on your vial to the lot number shown above.
- How GPC Uses the Results
- GPC reviews the reported results when selecting inventory. Inventory testing is held to a 99.00% acceptance standard for the purity reported on the batch certificate. A batch with no publishable results is not offered for sale.
For more detail on how GPC selects inventory and publishes evidence, read the Quality Standard (opens in a new tab) and the Certificate of Analysis Policy (opens in a new tab). To test a vial you received, get written pre-approval under the GPC Verification Program Terms (opens in a new tab). The program covers one vial per SKU from a member kit requested within 60 days of delivery; public single vials are not eligible. Approved account credit includes the price paid for that vial and eligible identity, net-content and purity laboratory fees, up to the amount approved in writing.
