Peptide Storage Guide
Proper storage plays an important role in maintaining the integrity and stability of research peptides. Whether storing peptides in their original lyophilised form or after reconstitution, following good storage practices can help preserve product quality throughout the research process.
All peptides supplied by Global Peptides are provided in lyophilised (freeze-dried) form. Lyophilisation significantly improves stability during storage and transport, helping to protect peptide integrity until the product is ready for reconstitution.
Why Are Peptides Supplied Lyophilised?
Lyophilisation is a freeze-drying process that removes water from the peptide under carefully controlled conditions.
Research suppliers commonly use this method because it:
- Improves long-term stability
- Helps reduce degradation during storage
- Makes transportation safer and more reliable
- Extends shelf life compared to liquid preparations
- Protects peptide integrity prior to reconstitution
This is why all Global Peptides products are supplied as a dry powder rather than as a pre-mixed liquid solution.
Storing Lyophilised Peptides
Lyophilised peptides are generally the most stable form for storage.
Best practices include:
- Store in a cool, dry location
- Keep away from direct sunlight
- Avoid excessive heat exposure
- Keep vials sealed until required
- Minimise exposure to moisture and humidity
For extended storage periods, researchers commonly utilise refrigeration.
Reconstituting Peptides
Before use in research applications, lyophilised peptides are typically reconstituted using a suitable solvent such as bacteriostatic water.

Reconstitution Guide
Storing Reconstituted Peptides
Once reconstituted, peptides generally become more sensitive to environmental conditions.
Researchers commonly follow these storage practices:
- Refrigerate after reconstitution
- Protect from unnecessary light exposure
- Avoid contamination during handling
- Return products to storage promptly after use
Storage requirements may vary between different peptides and research protocols.
Receiving and Handling Peptides
When receiving peptide products:
- Inspect packaging upon arrival
- Store products promptly
- Avoid leaving vials exposed to excessive temperatures
- Follow recommended storage practices as soon as possible
Proper handling from the point of delivery helps maintain product quality throughout storage.
Frequently Asked Questions
Do lyophilised peptides need refrigeration?
No, although this can vary depending on the peptide and expected storage duration. For long-term storage (6 months+) researchers commonly use refrigeration.
Why are peptides supplied as a powder?
Lyophilised peptides generally offer superior stability compared to liquid preparations, making them better suited for storage and transport.
What should I use to reconstitute peptides?
Many researchers utilise bacteriostatic water for peptide reconstitution.
Where can I learn how to reconstitute peptides?

How should peptides be stored after reconstitution?
Researchers commonly store reconstituted peptides under refrigerated conditions and minimise exposure to heat, light, and contamination. Storage requirements may vary depending on the specific peptide and research protocol.
