A site visit, whether conducted in person or virtually, remains one of the most informative steps in qualifying a peptide raw material manufacturer, surfacing details that documentation review alone often cannot reveal.

Areas to Observe During a Site Visit

  • General facility organization, cleanliness, and apparent adherence to documented procedures during actual operations
  • Analytical laboratory equipment and whether it appears well-maintained and appropriately calibrated
  • Warehouse and cold storage areas, including temperature monitoring systems for temperature-sensitive materials
  • Document control practices, such as how batch records and SOPs are managed and version-controlled
  • Staff familiarity with quality procedures when asked informal questions during the tour

 

Questions Worth Asking During the Visit

Beyond a scripted tour, buyers benefit from asking open-ended questions of staff at different levels — not just management — about how specific procedures are actually followed day to day, since discrepancies between documented procedure and actual practice are often more visible through informal conversation than formal presentation.

Virtual Audit Considerations

When an in-person visit is not feasible, a well-structured virtual audit using live video walkthroughs of key areas, combined with document review conducted via screen-share, can substitute reasonably well for many qualification purposes, though it is generally more limited in surfacing physical facility issues than an in-person visit.

Documentation to Request During or After the Visit

Buyers should request to review (or receive copies of) relevant SOPs for critical processes, recent internal audit findings if the manufacturer is willing to share them, and any third-party certification audit reports, in addition to what is observed directly during the visit.

Following Up After the Visit

A useful site visit concludes with a written summary of observations and any open items requiring follow-up before final supplier approval, creating a documented record that supports both the initial qualification decision and any future re-audit for comparison.
