Lab Results

Lab results on GoPeptides show third-party purity and content checks for research peptide batches. Open a product report to view measured values and, when available, scan images of the Certificate of Analysis. Reports support laboratory documentation — not medical advice.

Why choose GoPeptides

Lab testing

On this page you'll find the Certificates of Analysis (CoA) for all our research peptides, published separately per product batch. Every batch we supply is independently tested via HPLC (high-performance liquid chromatography) for purity, supplemented by mass spectrometry to confirm molecular identity.

This lets you check, before using the product in your research, exactly which purity percentage and identity confirmation belong to the lot number on your packaging. Why choose GoPeptides: we publish batch-specific reports rather than generic specifications, so you never have to take a purity claim on trust.

Each batch report states the testing laboratory, the test date, and the methodology used. Lab testing: HPLC analysis determines the purity percentage based on the peak area of the main product relative to any by-products, while mass spectrometry confirms the exact molecular mass against the theoretical value.

This combination of techniques ensures that both the purity and identity of each peptide are established independently before the product is supplied to laboratories.
