How to store Melanotan-1 (MT-1)
Practical storage protocol for Melanotan-1 (MT-1): temperature, light, reconstitution timing, and shelf life in a research setting.
Lyophilised (freeze-dried) storage
Unreconstituted Melanotan-1 (MT-1), like most research peptides, is stable when stored in its original sealed vial at -20°C for long-term storage. For short-term use (under 3 months), refrigeration at 2-8°C is acceptable. The vial must be protected from direct light and moisture.
Peptify dispatches Melanotan-1 (MT-1) in temperature-tolerant packaging from the UK, usually arriving within 24-48 hours of dispatch.
After reconstitution
Once Melanotan-1 (MT-1) is reconstituted with bacteriostatic water (BAC water, 0.9% benzyl alcohol), the solution should be stored at 2-8°C (refrigerated) and used within 28 days. Bacteriostatic water's preservative system inhibits microbial growth for roughly four weeks after first puncture — significantly longer than sterile water, which must be used immediately.
Avoid freeze-thaw cycles. Never leave the vial at room temperature for extended periods, and keep it in its original rubber-stoppered vial to minimise contamination risk.
Shelf life and quality verification
Peptify publishes a batch-specific expiry date on every Melanotan-1 (MT-1) COA, alongside HPLC chromatogram data and mass spectrometry confirmation. The full Certificate of Analysis for your specific batch is downloadable from the product page.

Frequently asked questions
What is the difference between MT-1 and MT-2?
MT-1 is a linear analogue of alpha-MSH that primarily targets MC1R for melanogenesis. MT-2 is a cyclic analogue with broader receptor activity.
