The melanocortin system is one of the most closely studied signalling families in receptor pharmacology. Five G-protein-coupled melanocortin receptors (MC1R through MC5R) sit at the centre of laboratory work on pigmentation, energy-balance signalling and central neural pathways, with the MC4R subtype drawing particular attention in in-vitro and preclinical models. This category collects the melanocortin-class reference compounds we supply for that research.
Every item here is intended strictly for in-vitro and laboratory research: characterising receptor-binding behaviour, developing assays and comparing structure to activity in a controlled setting. Nothing in this category is a supplement, medicine or product for human or animal consumption, and we make no dosing, therapeutic or before-and-after claims of any kind.
Each compound is supplied lyophilised, manufactured to a ≥99% purity target. Orders ship tracked from inside Europe, which means shipments to European destinations. Independent testing by Janoshik Analytical is published per product as each is tested; read how we approach it on our testing-standard page.
141 Peptide is the catalogue name for bremelanotide, also identified as PT-141 in scientific literature. It is a synthetic cyclic peptide that acts at melanocortin receptors. See the 141 Peptide identity and research evidence for compound-specific documentation.
No. Bremelanotide activates several melanocortin receptor subtypes; MC1R and MC4R are particularly relevant in its pharmacology. Describing research as MC4R-focused does not mean the compound acts only at MC4R. The prescribing information, section 12.1, also states that the mechanism of its clinical effect is unknown. That medicine documentation does not establish equivalence with a laboratory vial.
MT2 is another melanocortin research compound. In a mouse study of signalling in the nucleus accumbens, researchers observed reduced food consumption and motivation to obtain food, without a measured change in metabolic rate under the tested conditions. This is evidence from a specific animal model, not proof of a human weight-loss benefit or a result that can be assumed for 141 Peptide. See MT2 research documentation and the metabolic research category for related context.
Melanocortin laboratory peptides are laboratory reference compounds that act on the melanocortin family of G-protein-coupled receptors (MC1R–MC5R). Much current in-vitro work focuses on the MC4R subtype and central signalling pathways. In this catalogue they are supplied strictly as reference material for laboratory investigation: receptor-binding assays, structure-activity comparison and method development.
No. Every product in this category is supplied for in-vitro and laboratory research use only. Nothing here is a supplement, medicine or product for human or animal consumption, and we make no dosing, therapeutic or outcome claims of any kind.
