How long to keep peptide procurement records: a retention schedule

The trigger matters as much as the number of years

Retention rules rarely say 'keep for 3 years from the purchase date'. They start the clock at an event: submission of a financial report, completion of a study, final disposition of equipment. Two records about the same peptide lot can therefore expire years apart. Write the trigger event next to each record type and the date it happened.

The rules below are the ones we found that can reach a lab buying research peptides. Your institution, funder or contract may set longer periods, and those win. Nothing here replaces your sponsored-programs office or records manager.

Rules that may apply

Federal awards: 2 CFR 200.334 requires recipients to keep award records for 3 years from submission of the final financial report, or from the quarterly or annual report for awards renewed that way. Records must be kept until resolution if litigation, a claim or an audit starts before the period ends, and agencies may extend the period in writing. Property and equipment records run 3 years from final disposition. [1] The NIH Grants Policy Statement, revised March 2026, applies the 3-year period from submission of the annual Federal Financial Report and says scanned images must be full, complete and accurate representations of the original. [2]

GLP studies: 21 CFR 58.195 sets the shortest of three periods: 2 years after FDA approves the application the study supports, 5 years after the results are submitted to FDA, or, if no application results, 2 years after the study is completed, terminated or discontinued. Samples of test articles need only be kept while their quality permits evaluation. [3]

Workplace safety: OSHA's records rule treats safety data sheets indicating that a material may pose a health hazard as employee exposure records, which are kept for 30 years. SDSs need not be kept for any set period if some record of the chemical's identity, where it was used and when, is kept for 30 years. [4] The OSHA laboratory standard requires labs to keep SDSs received with incoming shipments and make them readily accessible. [5]

GMP manufacturers, for comparison only: ICH Q7 asks for production, control and distribution records to be kept at least 1 year after the batch's expiry date, or at least 3 years after complete distribution for materials with a retest date. [6] This binds manufacturers, not research buyers, but shows what a supplier with a GMP system should be able to produce later.

Schedule by record type

The minimum column applies the rules above. Where no rule applies, we suggest a lab default of keeping records until the lot is fully used or disposed of, plus any open claim or corrective-action period. That default is our suggestion, not a requirement.

Worked example

A fictional lab buys two lots of a research peptide on an NIH award in 2026 and uses them only in exploratory laboratory work, not a GLP study. The award's annual financial report covering the purchase is submitted on 2027-01-29.

Invoices, quotes, certificates and receiving records: keep until at least 2030-01-29, 3 years from that report, unless an audit begins first, in which case keep them until it closes. [1] [2] Safety data sheets: the lab may keep the SDSs themselves, or keep a record of the chemical's name, the rooms where it was used and the dates of use; whichever record the lab relies on must last 30 years, to 2056. [4] Freezer logs: no GLP clock applies, so the lab's own policy governs.

If one lot had been used in a GLP study, its certificate, receipt record and characterization data would also follow 21 CFR 58.195, which could run to 5 years after the results are submitted to FDA. [3] Keep the longer of the two periods.

Holds, transfers and destruction

A hold stops the clock. Under 2 CFR 200.334, litigation, claims or audit findings that begin before the period ends keep the records alive until resolved. [1] Mark held records clearly so routine clean-ups skip them.

Under the GLP rule, if a testing facility goes out of business its raw data and documentation transfer to the sponsor's archive and FDA must be notified in writing. [3] The GLP archive rule also expects one person responsible for the archive, controlled access and indexing for prompt retrieval. [7] A small lab can copy those habits: one owner for the procurement archive and an index by supplier and lot.

When records reach the end of their period, record what was destroyed, when and on whose approval. That destruction log is the evidence that a missing record was disposed of on schedule rather than lost.

Checklist

Use this once a year, or when an award closes.

• List each funding source for peptide purchases and the date of each financial report.
• Flag any lot used in a GLP or regulated study and note the study completion and submission dates.
• Confirm SDSs, or a 30-year identity record of chemical, place and dates of use, are held for every hazardous chemical received.
• Check for open audits, claims or disputes before destroying anything.
• Ask your institution's records office whether its schedule is longer than the federal minimum.
• Record every destruction with date and approver.
