What Is Melanotan II?
Melanotan II is a melanocortin peptide supplied by Peptegrity for research and educational purposes. This page provides a factual educational overview of Melanotan II, including its classification, biological target, research background, terminology and published study context. It is not a product page and does not provide dosing instructions, treatment recommendations or personal-use guidance.
Type of compound
Melanotan II is a synthetic cyclic heptapeptide analog of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH). It is classified as a melanocortin receptor agonist that binds to multiple melanocortin receptors.
Biological target and mechanism
Melanotan II functions as a non-selective agonist at melanocortin receptors, particularly MC1R, MC3R, MC4R, and MC5R. In research models, the activation of these receptors is studied for its role in modulating melanogenesis and signaling pathways associated with sexual function [2].
Research background
Initial research into Melanotan II focused on its potential to induce skin pigmentation through the stimulation of melanocytes [1]. Subsequent investigations expanded to examine its neurological and physiological effects, including its influence on erectile function and potential systemic responses in preclinical and clinical environments [1][2].
Current research and development status
Melanotan II is currently an investigational research chemical and is not an approved medication. Multiple clinical trials were historically conducted, but it has not received regulatory approval for human therapeutic use [1][2].
Published research context
Published literature covers a range of study areas, including its pharmacodynamic effects on pigmentation and erectile response [1][2]. Recent reports have shifted to documenting observations of systemic toxicity, rhabdomyolysis, and renal concerns associated with its use in uncontrolled settings [3][4][5].
Relevant terminology
Melanocortin receptors are a family of G-protein-coupled receptors involved in various physiological processes. Melanogenesis refers to the biological process of producing melanin, the pigment responsible for skin and hair coloration.
Storage and handling terminology
Research peptides should typically be stored in a cool, dry environment, often at -20°C or lower for long-term stability once lyophilized. Handling requires aseptic techniques in a laboratory setting to maintain compound integrity and prevent contamination.
Testing and Certificate of Analysis (COA)
A Certificate of Analysis (COA) is a document issued by a laboratory that confirms the purity, identity, and composition of a chemical batch. Researchers typically rely on COAs to verify that the Melanotan II sample meets required standards for experimental consistency.
Regulatory status
Melanotan II is not approved by the FDA, TGA, or other regulatory bodies for human use. It is strictly limited to research and development purposes in authorized laboratory environments.
