Storage & handling

Before reconstitution

• Store lyophilized (freeze-dried) peptides in a freezer at -20°C (-4°F) for long-term storage.
• If you plan to use a vial within a few weeks, refrigeration at 2–8°C (36–46°F) is sufficient.
• Keep vials in their original packaging, away from direct light and moisture.

After reconstitution

• Refrigerate reconstituted peptides at 2–8°C at all times.
• Most reconstituted peptides remain stable for roughly 2–4 weeks under refrigeration, though stability varies by compound — check the product page for specifics.
• Avoid repeated freeze-thaw cycles, which can degrade peptide structure.
• Do not leave reconstituted vials at room temperature for extended periods.

General handling

• Always use sterile technique when drawing from or injecting into a vial.
• Avoid exposing vials to direct sunlight, heat, or vibration.
• Do not shake vials — swirl gently instead.
• Keep all products out of reach of children and animals.
• Dispose of needles and sharps in an approved sharps container.
