Not perfect but better than most. COA was batch specific, chromatogram included. Support answered a question about storage within a day. Minor packaging ding on the second order but peptide itself seemed fine in our QC checks.

💡 First order was great. Second batch COA took a few days to show up on the site even though the vial shipped. Purity was still ok when it posted but the lag was annoying for our notebook records.

💡 Documentation quality varies by SKU on Apex Peptides. Some peptides ship with full third-party reports, others with a generic spec sheet until you email support. Usable for RUO but not set-and-forget.
