Melanotan II
Non-selective melanocortin agonist for pigmentation and appetite research.
Class
Cyclic α-MSH analogue
Half-life
~2 h
Studied in
Pigmentation and appetite pathway studies.
What it is
Melanotan II is a cyclic α-MSH analogue with broad melanocortin receptor activity (MC1R/MC3R/MC4R) used in pigmentation and central appetite-pathway research.
Mechanism studied
Non-selective melanocortin receptor agonist (MC1R/MC3R/MC4R).
Research notes
- Receptor non-selectivity yields multi-axis effects in research models.
Before sourcing any material
- Confirm a lot-matched third-party certificate of analysis (HPLC purity and mass-spectrometry identity).
- Check the stated peptide content per vial, not just the gross vial mass.
- Plan reconstitution volumes first so the vial size matches your protocol.
- Verify what is lawful in your jurisdiction — these are in-vitro research reagents, not medicines.
