Storing Peptides

The stability of each peptide is fairly unique and largely dependent on its sequence. Peptides are susceptible to degradation when exposed to improper conditions. They can be affected by sunlight, oxygen, and time.

All of our peptides are in lyophilized form and should be stored in a dry environment. Lyophilized peptides are standard form for preservation and work well for shipping environments. Short-term temperature changes that occur during shipping should not affect product life or efficacy.

For maximum stability, peptides should be stored in a freezer at -20 degrees C and away from bright light. Most peptides are stable for at least 12-18 months in these conditions. Try to avoid using a frost-free freezer because repeated changes in moisture and temperature may affect stability. Bear in mind peptides that go through repeated freeze-thaw cycles are also susceptible to degradation.

Keep peptides away from sunlight. Dark storage keeps them viable longer. Keep a secure lid on the vial to avoid oxidation.

Allow any frozen peptides to reach room temperature before reconstitution to maintain best quality. Store any remaining lyophilized peptide in the freezer at -20 degrees C.

It is not recommended to store excess peptide in solution for any extended period of time. The shelf life of peptides in solution is very limited, especially for certain types of peptides.

Evolution goes to great measures to make sure your peptides are pure and ship under the right circumstances so they arrive ready to go. Make sure you are prepared to keep them that way. Peptides that have been destroyed as a result of improper storage will not be eligible for refund or exchange.
