Melanotan I (MT1)
Melanotan I (MT1), also known as Afamelanotide, is a high-purity synthetic peptide analog of the endogenous alpha-melanocyte-stimulating hormone ($\alpha$-MSH). Composed of 13 amino acids, MT1 is a non-selective agonist of the Melanocortin receptors (primarily MC1R). In the field of photobiology and dermatological research, MT1 is distinguished by its ability to stimulate eumelanin production—the photoprotective pigment—independently of UV radiation exposure. This provides researchers with a sophisticated experimental model to investigate systemic photoprotection, the mechanisms of DNA repair in skin cells, and the mitigation of phototoxicity in research models of erythropoietic protoporphyria (EPP).
Our Melanotan I is synthesized in an ISO 9001:2015 certified and GMP-grade manufacturing environment. Utilizing advanced Solid-Phase Peptide Synthesis (SPPS) and high-resolution HPLC purification, we achieve an ultra-high chemical purity of ≥99%. This meticulous production standard ensures the peptide is free from truncated sequences and residual synthesis reagents, guaranteeing the consistency and structural fidelity required for high-stakes studies into melanocortin signaling and pigmentary homeostasis.

Key Features & Quality Assurance
Pharmaceutical-Grade Lyophilization
Our proprietary vacuum-sealing process ensures the Melanotan I powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid, clear reconstitution and protects the sensitive peptide sequence from oxidative degradation during long-term storage.
Structural Fidelity & Stability
Every batch undergoes strict Mass Spectrometry (MS) to confirm the 13-amino acid sequence, ensuring maximal receptor binding affinity and reproducible results in laboratory assays.
Reconstitution & Storage
Reconstitution Guide
-
Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the MT1 cake is at the base.
-
Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.
-
Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.
Storage Protocols
-
Long-term: Store at -20°C (Maintains potency for up to 24 months).
-
Short-term: Stable at 2–8°C for up to 3 months.
