Storing peptides correctly is essential for maintaining their quality and ensuring the best results. With proper storage habits, you can prevent early breakdown, avoid contamination, and keep your peptides reliable from the moment they arrive to the final dose. Follow the steps below to maintain the best possible quality and optimal shelf life.

Storing Freeze-Dried Peptides

During Shipping
Pantheon Peptides are freeze-dried (lyophilized) and can safely handle short periods at room temperature, so standard shipping times do not affect their quality. Each order is packaged with cold packs and insulated materials to reduce heat exposure and keep the peptides in excellent condition during delivery.

Short Term Storage
For short periods under 1 month, store peptides in the refrigerator at 2 to 8 °C. This keeps them cool and stable while preventing early breakdown, making it ideal when you plan to use them soon.

Long Term Storage
If you need to store peptides for many months or even years, place them in the freezer at minus 20 °C or colder. Freezing slows natural degradation and helps maintain their potency for up to two years.

Avoid Repeated Freeze Thaw Cycles
Avoid thawing and refreezing peptides over and over. Each cycle can cause condensation inside the vial, which weakens the peptide and shortens its shelf life.

Additional Storage Tips
Always keep vials sealed tightly, standing upright, and stored away from light and moisture. A tight seal prevents contamination and evaporation, while an upright position reduces the chance of leaks or pressure changes affecting the solution.

Storing Reconstituted Peptides

Only Reconstiture with BAC Water
Bacteriostatic water (BAC) contains a small amount of benzyl alcohol that helps prevent bacterial growth, keeping the peptide stable and reducing the risk of contamination.

Do Not Shake the Vial
Shaking can break down the delicate peptide chains, so gently swirl or tilt the vial instead of shaking it.

Refrigerate Immediately
Place the peptide in the refrigerator at 2 to 8 °C immediately after reconstitution to protect it from breaking down and to keep the solution stable. Do not leave reconstituted peptides at room temperature for more than one hour since warmth speeds up degradation and lowers effectiveness.

Use Within 30 to 45 Days.
Peptides slowly lose potency after mixing, so it is best to use them within this timeframe for consistent and reliable results.

Do Not Freeze Reconstituted Peptides.
Freezing can make the mixture unstable. It may cause separation or form ice crystals that can damage the peptide and reduce its overall stability.

Label the vial.
Label the vial with the date of reconstitution and the concentration to track storage time and ensure accurate dosing.

Additional Storage Tips
Always keep vials sealed tightly, standing upright, and stored away from light and moisture. A tight seal prevents contamination and evaporation, while an upright position reduces the chance of leaks or pressure changes affecting the solution.

Conclusion

By following these storage guidelines, you can keep your peptides fresh, stable, and effective for as long as possible. A little care goes a long way in protecting their quality. We hope this guide helps you feel confident in handling your products, and we wish you the best on your wellness journey.
