Why storage matters

Peptide stability can be affected by temperature, light, agitation, and repeated contamination risk during handling. Product-specific instructions always take priority.

Temperature control basics

  • Follow label-defined temperature ranges exactly when available.
  • Avoid repeated warm/cold cycling when possible.
  • Do not assume all lyophilized or reconstituted products share the same stability window.

Light and moisture protection

  • Many sensitive compounds are stored in original containers to reduce light exposure.
  • Keep stoppers/caps clean and dry; moisture intrusion can increase degradation risk.

Contamination prevention during handling

  • Use aseptic technique for every vial access.
  • Disinfect stoppers before puncture and use new sterile supplies each time.
  • Minimize unnecessary punctures and handling events.

Labeling and tracking best practices

  • Write reconstitution date/time and concentration on the vial.
  • Track lot numbers and source details.
  • Discard material with unexpected cloudiness, particles, or labeling uncertainty.

Travel and transport notes

  • Use temperature-aware transport (insulated options + validated cold packs as needed).
  • Avoid leaving temperature-sensitive products in parked vehicles.
  • Document time out of range if excursions occur.
