Peptide Storing Guide: How to Keep Your Peptides Safe and Effective
At Proto Peptide, we understand the importance of proper peptide storage. Correct handling ensures your peptides remain stable, sterile, and ready for research purposes. This guide provides step-by-step instructions to help you store your peptides safely and maintain their integrity.
1. Shipping and Packaging
All peptides from our store are shipped in freezer-and fridge-safe containers. These containers are designed to:
- Protect the peptide vial from physical damage during transit
- Maintain a contaminant-free environment
- Ensure the vial remains stable and ready for safe storage
By shipping in these specialized containers, we minimize the risk of exposure to temperature fluctuations, moisture, and contamination, keeping your peptides in optimal condition upon arrival.
Tip: Don't throw away the container and use it to hold your peptide vials in the fridge and freezer.
2. Storing Your Peptides
Peptides are sensitive to environmental conditions. Follow these storage tips to preserve their stability:
- Refrigeration: once reconstituted, peptides that are intended for short-term use should be stored in a fridge at 2–8°C (36–46°F). Follow our reconstitution guide and reconstitution calculator for more tips on reconstitution.
- Freezing: For long-term storage, peptides in their powder form (not yet reconstituted, exactly how you receive them) can be put in a freezer at -20°C (-4°F) or lower.
Tip: Avoid repeated freeze-thaw cycles, which can degrade peptide quality over time.
3. Vial Handling and Sterility
Each peptide vial comes with a tamper-proof, sterile lid. It is important to follow these guidelines when handling your vial:
- Once the lid is removed, it cannot be replaced, so care must be taken to maintain sterility.
- Always use alcohol wipes to clean the top of the vial before accessing its contents.
- Wiping the vial ensures that your peptide remains free from contamination, reducing risk during reconstitution or research applications.
Tip: Proper handling protects both the peptide’s integrity and your research results.
4. Reconstitution Guidelines
Before use, peptides must be reconstituted according to the manufacturer’s instructions. To ensure accuracy:
- Follow our Reconstitution Guide carefully
- Use our Reconstitution Calculator to determine the correct volume of bacteriostatic water
- Always handle vials with clean hands and use sterile equipment during reconstitution
Proper reconstitution not only preserves peptide integrity but also ensures accurate dosing for research applications.
5. Summary of Best Practices
- Ship and store peptides in fridge- or freezer-safe containers.
- Wipe the vial top with alcohol every time after removing the lid.
- Store peptides at the recommended temperature (fridge or freezer).
- Avoid repeated freeze-thaw cycles.
- Use our Reconstitution Guide and Calculator for precise preparation.
By following these best practices, you ensure your peptides remain safe, sterile, and effective for all research purposes.
