Description
Melanotan II 10 mg
Buy Melanotan II 10 mg for laboratory research, supplied as lyophilized powder in one boxed 3 mL vial.
Melanotan II, also called MT-2, is a synthetic cyclic peptide studied in melanocortin research.
Why the cyclic structure matters
The reference Melanotan II structure contains a lactam bridge: a covalent link between amino-acid side chains that closes part of the peptide into a ring. Its structure differs from linear Melanotan I.
PT-141 is related but has different terminal chemistry. Matching a short name or the number of residues is not enough to substitute one ligand for another. Retain the sequence, ring connection and terminal groups when matching the product to a published method.
Reading the structure-activity evidence
A primary cyclic-analog study synthesized seven lactam peptides and compared their responses in frog and lizard skin bioassays. Changes in ring size affected the measured activity, and the two assay systems did not give identical potency relationships.
The useful distinction is between a defined peptide in a defined test and a broad claim about the compound. Relative potency from one bioassay is not a universal property, nor is it a measurement of the purity or content of a commercial batch. Those findings provide research context without establishing a human-use outcome.
Presentation and documentation
This listing is for powder, not a spray or prepared solution. The 10 mg label describes the amount per vial; the container’s 3 mL capacity does not specify a solvent volume or resulting concentration.
Open COA & Documents for available product files and batch reports. Confirm the identity and lot on the record before reviewing analytical results. Compare reported purity and content separately, and use handling and storage information that applies to the actual material and your assay. Published work on another analog or formulation does not verify this lot.
