Important Note Regarding Certificates of Analysis
Due to trademark considerations, we have transitioned our company name from Imperial Peptides to Gold Standard Peptides. As a result, some Certificates of Analysis (particularly for earlier batches) may still display the previous name, Imperial Peptides. All new Certificates of Analysis going forward will reflect our current name, Gold Standard Peptides.
We partner with two independent testing facilities. On occasion, one laboratory may temporarily pause accepting new samples due to high volume and queue capacity. In those instances, we utilize our second accredited facility to maintain timely and reliable testing without interruption.
All products continue to undergo the same rigorous third-party testing standards regardless of which laboratory performs the analysis or which company name appears on the COA.
COAs
Research peptides can’t be judged by appearance. A Certificate of Analysis from a third-party lab is the only reliable way to confirm what’s actually in the vial.
We test every batch for purity and endotoxins so you know the product meets the standards listed on the label — not just the claims on a website.
