- Different storage approaches produce measurably different shelf life outcomes for Melanotan-1 vials. The table below compares four common storage methods across stability duration, potency retention at endpoint, and practical limitations.
- Lyophilised vial at -20°C (unopened)
- 6–12 months
- 95–98%
- Freeze-thaw cycles during shipping
- Optimal for long-term storage; requires freezer access
- Reconstituted vial at 2–8°C (refrigerated, light-protected)
- 28 days
- 90–95%
- Hydrolysis and temperature fluctuations
- Standard protocol; requires consistent refrigeration
- Reconstituted vial at 2–8°C (refrigerated, clear glass, ambient light)
- 14–21 days
- 80–88%
- Photodegradation plus hydrolysis
- Light exposure accelerates loss; easily preventable
- Reconstituted vial at 20–25°C (room temperature)
- 3–5 days
- 60–75%
- Rapid hydrolysis
- Unacceptable for multi-dose use; degrades too quickly
- The clearest takeaway: temperature control is non-negotiable, but light protection is nearly as critical for reconstituted vials. A vial stored in a standard home refrigerator in clear glass under interior lighting loses 10–15% more potency over 28 days than an identical vial wrapped in foil or stored in amber glass. That's the difference between a vial that remains therapeutically effective at day 28 and one that's dropped below minimum effective concentration.
