Description

OVERVIEWProduct overview

Melanotan II is a cyclic analogue of alpha-MSH with activity across several melanocortin receptor subtypes.

It is used as a reference agonist in receptor pharmacology research.

All published work is preclinical or investigational. This material is supplied as a laboratory reference compound and is not authorised as a medicine in Ireland, the UK or the EU.

SUPPLY IN IRELANDMelanotan II Ireland — supplied to research laboratories

Research groups across Ireland buy Melanotan II from Kensington Laboratories as a lyophilised Melanotan II peptide, released only against a batch-matched certificate of analysis. Every vial of high purity Melanotan II is verified by HPLC and LC-MS before it leaves the facility, so laboratories ordering Melanotan II in Ireland receive material with documented purity and identity.

Laboratory Melanotan II is packed for controlled storage and sent by tracked delivery in 3–5 days to Dublin, Cork, Galway, Limerick and the rest of Ireland. Delivery costs €9.90 per order. Teams planning MelanotanII research can review the specifications, certificate of analysis and reference list on this page before ordering.

Institutions searching for Melanotan II peptide suppliers in Ireland typically compare purity, batch documentation and delivery times. Each of those is published here: a 99% HPLC purity specification, a certificate matched to the batch code on your vial, and tracked delivery in 3–5 days.

Melanotan II is supplied strictly for laboratory research use only. It is not a medicine and is not for human or veterinary consumption.

RESEARCHResearch overview

The following summary is provided for educational and scientific context only. It describes what has been observed in published laboratory and animal studies and does not represent established clinical outcomes, medical advice or a claim of efficacy in humans.

Background

Melanotan II is a cyclic analogue of alpha-MSH with activity across several melanocortin receptor subtypes.

It is used as a reference agonist in receptor pharmacology research.

All published work is preclinical or investigational. This material is supplied as a laboratory reference compound and is not authorised as a medicine in Ireland, the UK or the EU.

Current research areas

Published investigation clusters around a small number of biological themes. Each remains experimental and none has been established as a therapeutic effect in humans.

  • MC1R and MC4R binding assays
  • Melanogenesis in cell culture
  • Central melanocortin signalling
  • Receptor selectivity profiling

Scientific context and proposed mechanisms

Non-selective melanocortin receptor agonism is reported, with MC1R engagement linked to melanogenesis and MC4R engagement to central endpoints.

Interpreting the evidence

Most published work in this area uses cell culture or rodent models with small group sizes and short observation windows. Independent replication varies considerably between compounds, and results are sensitive to species, route, dose and endpoint.

There is no regulatory-approved human protocol for this compound. Any laboratory protocol should be defined by the model under study, institutional ethical approval, appropriate controls and predefined endpoints.

    FAQSFrequently asked questions
    What is Melanotan II?
    Melanotan II is cyclic synthetic melanocortin receptor agonist, also referred to in the literature as MT-II. Laboratory interest centres on melanocortin receptor pharmacology models. It is not a licensed medicine and is supplied for research use only.
    What quantity of Melanotan II is supplied?
    Each vial of Melanotan II contains 10 mg of lyophilised powder. Vials are individually sealed, with the batch number and expiry date printed on the label so stock can be matched to its published certificate of analysis.
    What purity is Melanotan II released at?
    Purity is the proportion of material that is the target peptide, with the remainder consisting of truncated sequences, salts and residual solvents from synthesis. It is measured by reverse-phase HPLC, and Melanotan II is released at 99% or higher.
    What does the certificate of analysis for Melanotan II show?
    The certificate reports the identity and purity of the exact batch you receive: the HPLC purity percentage, mass confirmation by LC-MS, the independent testing laboratory, the batch number and the test date. Every batch of Melanotan II is tested before release.
    Is Melanotan II suitable for human use?
    No. Melanotan II is supplied strictly for in-vitro and preclinical laboratory research by qualified professionals. It is not for human or veterinary consumption and is not licensed as a medicine.
    What is Melanotan II studied for in research models?
    Published work using Melanotan II concerns mc1r and mc4r binding assays, melanogenesis in cell culture, central melanocortin signalling. All of this is preclinical, and none of it establishes a therapeutic use in humans.
    Is Melanotan II legal to buy in Ireland?
    Melanotan II may be supplied and purchased as a laboratory reference compound for research use only. It is not an authorised medicine in Ireland, the UK or the EU, and it must not be presented, sold or used as a treatment for any human or animal condition.
    How should Melanotan II be stored?
    Sealed lyophilised vials of Melanotan II are held at 2–8°C for short periods and at −20°C for long-term storage, protected from light. Once reconstituted, solutions are refrigerated and used within a short window; freeze–thaw cycling should be avoided.
    How much bacteriostatic water should be used with Melanotan II?
    There is no single correct volume — the amount of diluent used simply sets the concentration of the resulting solution. Many laboratories choose a round figure such as 2 ml per vial to keep calculations straightforward. Bacteriostatic water is not supplied and is purchased separately.
    How quickly is Melanotan II delivered in Ireland?
    Orders placed before the daily cut-off are dispatched with €9.90 tracked delivery in 3–5 days to Dublin, Cork, Galway, Limerick and addresses nationwide. Packaging is discreet and a tracking number is emailed on dispatch.
