Storage & Reconstitution
Store lyophilized Melanotan II at 2-8°C for routine laboratory storage or -20°C for extended preservation. Following reconstitution with Bacteriostatic Water, keep refrigerated and minimize repeated freeze-thaw cycles. Introduce solvent slowly against the vial wall to preserve peptide integrity and reduce foaming.
Every production batch undergoes independent HPLC purity testing and mass spectrometry identity verification before release. View third-party Certificates of Analysis (COAs) on our Lab Results page.
Researcher Inquiries
Melanotan II is a synthetic analogue of alpha-melanocyte-stimulating hormone (α-MSH). Laboratory research primarily investigates its interaction with melanocortin receptors including MC1R, MC3R, MC4R, and MC5R.
Researchers commonly study Melanotan II for melanocortin receptor signaling, pigmentation biology, melanogenesis, photoprotection, and related metabolic pathways within controlled laboratory environments.
Melanotan II is commonly reconstituted using Bacteriostatic Water. Introduce the solvent slowly against the inside wall of the vial and gently swirl until fully dissolved without vigorous shaking.
Store the lyophilized peptide refrigerated until use. After reconstitution, keep the solution refrigerated and protected from excessive heat and light during laboratory storage.
Yes. Every batch of Melanotan II is independently verified by HPLC purity testing and mass spectrometry, with Certificates of Analysis available through our Lab Results page.

New to this so I was really surprised. I literally got a deep tan within a week and a half with barely any sun. Saved me time from having to go to a tanning bed or sun bathing
