Solid-state evidence
Temperature, moisture, light, container closure and duration matter.
FORMULATION-SPECIFIC EVIDENCE
Storage + Stability
Separate common handling practices from validated stability data.
STORAGE + STABILITY DATABASE
“Keep refrigerated” is not a stability study.
Solution evidence
Vehicle, pH, concentration, temperature and analytical endpoint matter.
Beyond-use evidence
Chemical stability and microbial suitability are different questions.
Handling evidence
Do not invent a universal freeze-thaw rule where compound-specific data are absent.
RESEARCH REBEL RULE
No universal 14-day or 30-day beyond-use period is assigned across peptides.
