How to Store Melanotan II

Proper storage of Melanotan II is critical for preserving peptide stability and ensuring consistent research results over time.

Lyophilized (Pre-Reconstitution)

Unreconstituted Melanotan II should be stored at -20°C for long-term storage or 2-8°C for short-term storage. Keep away from light and moisture. Lyophilized peptides are generally stable for 24+ months when stored properly.

Reconstituted

After reconstitution with bacteriostatic water, Melanotan II should be refrigerated at 2-8°C and used within 4-6 weeks. Avoid repeated freeze-thaw cycles as this can degrade the peptide.

General Guidelines

• Keep in original sealed vial until ready for use
• Protect from direct light exposure
• Maintain consistent temperature — avoid temperature fluctuations
• Use sterile technique when accessing reconstituted vials
