Mechanism
Melanotan II is a conformationally constrained cyclic lactam heptapeptide. It retains the conserved His-Phe-Arg-Trp core motif, with three engineered modifications relative to the parent linear sequence: substitution of methionine by norleucine, inversion of L-phenylalanine to D-phenylalanine, and a side-chain-to-side-chain lactam bridge (Asp–Lys) that locks the backbone into a defined turn conformation. These changes are associated with reduced susceptibility to enzymatic cleavage in vitro and constrain the bioactive conformation. The constrained scaffold is widely used as a reference ligand for characterizing the binding and selectivity profile of class A (rhodopsin-like) G-protein-coupled receptors in radioligand and structural-biology studies.

Frequently asked questions
What is MT-2?
MT-2 is a synthetic cyclic heptapeptide (cyclic lactam, 7 residues) studied as a conformationally constrained reference ligand in class A GPCR binding, structure-activity chemistry, and structural-biology research.
What sizes does MT-2 come in?
MT-2 is supplied as a lyophilized powder, in 10 mg vials. The 10 mg is in stock.
How is MT-2 tested?
Every lot is tested by Freedom Diagnostics Testing, PLLC in Franklin, Tennessee, an independent laboratory: purity by HPLC and identity by mass spectrometry. A lot goes on sale only after its certificate is published.
Where is the certificate of analysis for MT-2?
Each vial's label carries its lot number, and every lot's certificate is at luvaminos.com/coa/ followed by the lot. The lot on sale now: MTII-10-001.
How do I know your peptides are real?
Every lot is tested by an independent lab, and you can check the result yourself on the lab's own website.
Tap View COA on any product or scan the QR code on your vial. Each certificate has a code you can look up with Freedom Diagnostics Testing, PLLC in Franklin, Tennessee, an independent US lab we don't own. See every certificate.
What purity do you hold every lot to?
99% or higher, tested on every lot.
Each lot's exact result is printed on its certificate, which you can open from the product page or by scanning the QR code on the vial.
