Peptide Research Documentation: GLP Compliance, Record Keeping, and Audit Trail Requirements
Protocol Guide | 2026-08-10 | 10 min read
Essential guide to peptide research documentation. Learn GLP requirements, record keeping best practices, audit trail maintenance, and documentation systems for regulatory compliance.
Introduction to Research Documentation
Documentation is the foundation of defensible, reproducible peptide research. Whether conducting GLP-regulated studies or exploratory research, proper documentation ensures data integrity, enables audit trails, and supports regulatory compliance. This guide addresses documentation requirements, best practices, and systems for maintaining comprehensive research records.
GLP Documentation Principles
Good Laboratory Practice Fundamentals
Core Principles:
- **Contemporaneous Recording:** Document activities at the time of performance
- **Original Data:** Record directly from source; no transcription
- **Indelible Records:** Permanent entries; no erasure
- **Attribution:** Clear identification of responsible personnel
- **Traceability:** Complete record of all activities
ALCOA+ Principles
Modern data integrity follows ALCOA+ standards:
| Principle | Requirement | |-----------|-------------| | Attributable | Who performed the action | | Legible | Clear, readable records | | Contemporaneous | Documented at time of performance | | Original | First recording of data | | Accurate | Truthful, complete reflection | | Complete | All data including repeats and failures | | Consistent | Standardized format and timing | | Enduring | Maintained throughout retention period | | Available | Accessible for review/inspection |
