Melanotan I is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) Melanotan I should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store Melanotan I?
Proper storage is critical for maintaining Melanotan I's potency and safety. As a Melanocortin-1 receptor (MC1R) agonist, Melanotan I is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized Melanotan I?
Unreconstituted (freeze-dried) Melanotan I: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted Melanotan I?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted Melanotan I. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if Melanotan I Has Gone Bad?
Reconstituted Melanotan I should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With Melanotan I?
Lyophilized Melanotan I can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted Melanotan I is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on Melanotan I Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.

Frequently Asked Questions
What is Melanotan I?
Melanotan I (Afamelanotide) is a Melanocortin-1 receptor (MC1R) agonist. Synthetic α-MSH analog developed to stimulate melanin production through selective MC1R activation. It is researched for skin pigmentation, phototoxicity reduction in EPP patients, UV-free tanning.
What is the recommended Melanotan I dosage?
Common dosages: 16 mg implant (FDA-approved); 0.025-0.3 mg/kg (research dosing) administered every 60 days (implant) or daily (injection) via subcutaneous implant (approved) or subcutaneous injection. Cycle length: 60-day implant cycles; 4-8 weeks injection cycles. Half-life: ~2 hours circulating; implant provides 2-month depot release. Use our peptide calculator for exact reconstitution math.
What are the side effects of Melanotan I?
Milder than Melanotan II: fatigue, headache, facial flushing, nausea, development or darkening of freckles/moles. Slower onset than MT-II (weeks vs days). Generally considered safer.
Is Melanotan I safe?
Melanotan I has shown a preliminary safety profile in research. FDA-approved as Scenesse for EPP only (prescription). Not approved for cosmetic tanning. All research should follow appropriate safety protocols.
