We don't issue verdicts — we publish the evidence and let it speak. Our automated site audit has verified the vendor's published catalogue and COA surface. So far we have captured no substantiated community reports and no lab documents for Synthesispeptides. That absence is itself information: it does not prove anything is wrong, but it means independent evidence is thin — proceed accordingly.
1 of 25 observed peptides have a COA mapped to them. Latest captured reports are from Nova Labs. We hold 1 older lab document, but none captured within the last 12 months.
