Storage Instructions

Handling and Storage Tips:

  • Keep peptides cold and away from light once received.
  • For short-term use (days to weeks), refrigeration at 4°C (39°F) is acceptable.
  • Lyophilized peptides are typically stable at room temperature for several weeks, making it suitable for moderate-term storage.
  • For long-term storage (months to years), it’s best to freeze peptides at -80°C (-112°F). Freezing optimally preserves peptide stability for extended periods.
