How to Store Your Peptides (Before and After Reconstitution)

Proper storage is essential to preserving the integrity of your peptides throughout your research journey.

Let’s break it down into two parts—how to store them before and after reconstitution.

Before reconstitution:
When your peptides arrive, they’re in a lyophilized (freeze-dried) powder form. While some choose to store them at room temperature short term, we recommend keeping them refrigerated (36–46°F or 2–8°C) to maximize stability.

If you’re not planning to use a peptide for several weeks or months, it’s best to store it in the freezer—just make sure to avoid frequent thaw-and-freeze cycles.

After reconstitution:
Once you’ve added bacteriostatic water to your peptide, it must be refrigerated. This helps maintain stability and minimizes the risk of bacterial contamination.

Use a clean, labeled vial and make sure it’s stored upright, away from the back of the fridge where freezing can occur.

Quick tips:

• Never store peptides in direct sunlight or humid areas
• Always use sterile supplies when handling
• Don’t shake the vial—gently swirl or roll if needed
• Travel with an insulated cooler if you're taking peptides on the go
• When in doubt, refer back to your peptide’s resource PDF or reach out to our support team. Safe handling protects your investment—and your research.

Top Recommended Supplies

Needles:

• 31G 0.5cc 5/16-inch – Ideal for doses up to 25 units (most common).
• 31G 1cc 5/16-inch – Better for 25–100 unit injections.

If these links don’t work in your region, search for “EZ Touch insulin syringes 31G” through a local supplier or pharmacy.

Travel Case:

• Insulated travel case – Keeps your peptides cool, discreet, and TSA-compliant while on the go.
