Melanotan II 10MG

Product Overview

Melanotan II 10MG is a synthetic cyclic melanocortin-receptor agonist research material, supplied as white to off-white lyophilised powder in a 10mg catalogue presentation (SKU ML10). This page describes the stated research identity and batch-oriented catalogue specification; it does not provide an administration protocol.

Melanotan II research examines melanocortin-receptor pharmacology, pigmentation pathways and centrally mediated behavioural responses. Study findings do not justify consumer or cosmetic use.

Research Context

The following themes summarise published research on the named molecule or components. They are research contexts, not claims about the supplied ExtolX batch.

Areas of Research

• melanocortin-receptor selectivity
• melanogenesis and pigmentation signalling
• central melanocortin pathways
• cyclic-peptide structure-function research

Evidence Quality and Limitations

Published research includes animal and limited human exposure data, but MHRA information highlights the absence of quality, safety and efficacy safeguards for unauthorised Melanotan II products.

Regulatory Context

MHRA information describes Melanotan II products as unauthorised medicines and warns that their contents and quality are not assured. ExtolX supplies this material strictly for laboratory research, not personal or cosmetic use.

Storage and Handling

Before reconstitution: Keep the lyophilised vial sealed, dry and protected from light at −20°C or below, subject to the batch-specific supplier documentation. Published Melanotan II reference-material data support frozen storage, but the counter-ion and formulation of this ExtolX batch have not been confirmed. Allow a cold vial to reach room temperature before opening to reduce condensation.

After reconstitution: Stability depends on the exact salt or formulation, solvent, concentration, pH and container. Prepare only what the validated method requires. If that method supports frozen storage, use single-use aliquots and avoid repeated freeze–thaw cycles. Use clean laboratory technique, avoid vigorous agitation, and record the preparation and storage history. No numerical solution shelf life has been verified for this ExtolX batch.

Compatibility Limitations

Do not infer solubility or stability from another peptide, blend, amount or pharmaceutical formulation. Use small-scale method development and appropriate analytical controls before committing valuable material.

Laboratory Safety

Handle only in an appropriately equipped laboratory by trained personnel. Use a task-specific risk assessment, suitable personal protective equipment and applicable safety documentation. Avoid ingestion, inhalation, skin contact and environmental release, and dispose of waste in accordance with local requirements.
