Melanotan 2 (10mg)

Alpha-MSH is a linear melanocortin peptide. Melanotan 2 shortens that motif and closes a lactam bridge between aspartic acid and lysine, which is why catalogs call it cyclic.^[1] The Dorr pilot paper writes the clinic compound as Ac-Nle4-Asp5-His6-D-Phe7-Arg8-Trp9-Lys10-NH2 with that bridge in place.

Research suggests the cyclic constraint is the structural fact that separates Melanotan 2 from linear alpha-MSH analogs. Receptor-subtype rankings belong in a binding assay, not in a consumer comparison. This page does not publish Ki values.

Melanotan 2 vs 1 traffic often wants a verdict on which analog tans better. This listing will not give it. The difference that belongs here is structure: cyclic heptapeptide versus linear analog.

The FDA has warned about unapproved melanotan products.^[2] Clinical trials have explored melanotan-II in small clinic pilots. Those pilots do not travel with this SKU as a use label.

Dorr, Lines, Levine, and colleagues ran a pilot phase I evaluation of melanotan-II at the University of Arizona.^[1] Design: three healthy male volunteers, single-blind, alternating-day saline or melanotan-II, clinic-administered. The paper is a first-in-human tolerability look at the cyclic analog, not a catalog protocol.

Cite that study for what it is. Three healthy male volunteers. Alternating-day saline or melanotan-II. A cyclic melanotropic peptide in a supervised University of Arizona setting. It does not set a laboratory reconstitution recipe, and it does not make this 10 mg vial a tanning product.^[1]

Melanotan 2 vs 1 is a backbone question. Melanotan 2 is cyclic. Melanotan 1 is linear, a [Nle4, D-Phe7] style analog of alpha-MSH. Same hormone family, different constraint on the chain.

The linear analog is listed separately as Melanotan 1. Pick the reagent that matches the structure the method names. Do not swap them because a forum thread treated them as two strengths of the same tan.

The vial label and the Certificate of Analysis have to name the same batch. This catalog lists a 10 mg lyophilized research vial. Melanotan 2 price is a vendor field. It does not override the FDA's unapproved-product warnings.^[2]

Melanotan 2 ships lyophilized. Store sealed vials at -20 C. Log diluent lot, concentration, date, and operator against the batch COA.
