Each product is supplied with a Certificate of Analysis (COA) from an independent laboratory. You can find COAs on the product page or on the dedicated COA resource page, or request the COA for your batch.
Some details on public COAs are redacted to protect supplier and batch information — this is normal. Specifically, supplier names, unique identifier codes, and specific manufacturer details are hidden. However, the core analytical results remain unredacted, including purity levels, peptide content, and identity confirmation. These details ensure customers can verify the quality and authenticity of the products.
To confirm the COA for the specific batch you received, email [email protected] with your order number (LAZ####) and we'll help you verify it.
