\nMelanotan II is a synthetic heptapeptide analogue of the endogenous hormone alpha\u2011melanocyte\u2011stimulating hormone (\u03b1\u2011MSH). Its sequence, Ac\u2011Ser\u2011Tyr\u2011Ser\u2011Norleu\u2011Glu\u2011His\u2011D\u2011Phe\u2011Arg\u2011Trp\u2011Gly\u2011Lys\u2011Pro\u2011Val\u2011NH\u2082 (cyclized via a lactam bridge between Asp and Lys residues), confers high affinity for several melanocortin receptors, particularly MC1R, MC3R, MC4R and MC5R. In laboratory settings, this compound is widely utilized to investigate melanogenesis, pigmentation signalling cascades, and receptor pharmacology. Researchers employ it in cell\u2011based assays, tissue explants, and preclinical animal models to study UV\u2011independent melanin synthesis and related endocrine pathways. The peptide is supplied as a lyophilized powder, typically accompanied by a certificate of analysis confirming identity, purity, and peptide content. Because Melanotan II is strictly a research chemical, it is not formulated, approved, or intended for any diagnostic, therapeutic, or veterinary application; all handling must comply with institutional guidelines for investigational compounds.\n<\/p>\n
\nThe wholesale price per gram of Melanotan II varies considerably, driven by several interconnected factors that research buyers must evaluate when sourcing material.\n<\/p>\n
\nPurity, typically assessed by reverse\u2011phase HPLC and confirmed by mass spectrometry, is the most direct cost driver. Peptide lots with a purity of \u226598%<\/strong> often command a premium, as achieving this level requires additional purification steps (e.g., multiple preparative HPLC runs), stricter quality control, and often results in lower overall yield from the synthesis. Material labelled \u226595%<\/strong> may be priced lower and is sometimes acceptable for preliminary binding studies, but researchers should align purity with the sensitivity of their experimental endpoints.\n<\/p>\n \nEconomies of scale are pronounced in peptide manufacturing. Synthesis of a single batch at the multi\u2011gram scale amortizes fixed costs \u2013 resin, reagents, solvent, labour, and equipment time \u2013 across a larger product mass. Consequently, per\u2011gram wholesale pricing drops markedly as order volume increases.\n<\/p>\n \nEstablished vendors that invest in ISO\u2011certified facilities, comprehensive analytical testing (including amino acid analysis, residual solvent analysis, and endotoxin quantification), and robust batch\u2011to\u2011batch consistency often set higher list prices. The added cost reflects the reliability of the documentation package and the lower risk of receiving degraded or misidentified material. Buyers who require third\u2011party verification or additional characterisation (e.g., circular dichroism, bioactivity assays) will see those services reflected in the quotation.\n<\/p>\n \nThe global research peptide market is sensitive to raw material availability (protected amino acids, resins), shipping constraints for temperature\u2011sensitive lyophilizates, and evolving regulatory requirements. Sudden increases in demand from academic consortia or pharmaceutical screening programs can tighten supply, while export restrictions, customs clearance delays, or fluctuations in air\u2011freight costs can push per\u2011gram prices upward. Suppliers also adjust margins based on regional competition and the presence of intermediary distributors.\n<\/p>\n \nBecause the market for Melanotan II is unregulated (no official pharmacopoeia monograph exists), there is no fixed price list. Observed per\u2011gram wholesale figures generally span a broad interval. Small purchases of 1\u20135 grams, where handling, aliquoting, and documentation overhead are high relative to mass, may attract per\u2011gram costs in the upper part of the spectrum. Orders in the 10\u201325 gram<\/strong> range commonly see a step\u2011down in unit price, while volumes exceeding 50 grams<\/strong> can reduce the per\u2011gram rate by 30\u201150% compared to smaller lots.\n<\/p>\n \nActual quotations are influenced by the purity tier (e.g., 95\u201198%<\/strong> ou \u226598%<\/strong>), whether the peptide is salt\u2011form (acetate or trifluoroacetate salt, with residual TFA content declared), and the inclusion of expedited cold\u2011chain shipping. Researchers are advised to request quotes from multiple reputable suppliers, specifying identical technical requirements (peptide sequence, purity, counterion, packaging) to enable meaningful comparison. The lyophilized powder is most commonly supplied in sterile, septum\u2011capped glass vials under argon or vacuum; alternative presentations (bulk jar, pre\u2011weighed aliquots) can affect unit cost as well.\n<\/p>\n \nVirtually all wholesale suppliers structure pricing in tiers that reward larger purchases. A typical framework might include:\n<\/p>\n \nMinimum order quantities (MOQs) are frequently applied at the lower tiers. For example, a supplier may require a minimum of 5 grams to access the \u201cwholesale\u201d bracket, with smaller amounts priced at a premium. Institutions planning longitudinal studies often consolidate projected annual usage into a single bulk order (assuming validated long\u2011term storage at \u201320\u202f\u00b0C with desiccation) to capture the lower per\u2011gram rate. It is critical to confirm that packaging preserves peptide integrity during multi\u2011year storage; vacuum\u2011sealed aliquots minimise freeze\u2011thaw cycles and moisture uptake.\n<\/p>\n \nThorough due diligence protects research programs from consuming time and resources on material of unknown integrity. Key steps include:\n<\/p>\n \nMelanotan II exists in a niche regulatory space; it is not approved by the U.S. Food and Drug Administration, the European Medicines Agency, or any analogous body for human or veterinary clinical applications, and it remains exclusively a laboratory research tool. Researchers and procurement officers must navigate several compliance dimensions:\n<\/p>\n \nWholesale pricing for Melanotan II per gram reflects a confluence of purity, volume, supplier capability, and market conditions. A methodical approach to sourcing \u2013 requesting detailed analytical documentation, comparing structured quotes, and evaluating the supplier\u2019s long\u2011term reliability \u2013 enables research programmes to secure material that meets experimental requirements without overspending. Cost should never eclipse considerations of quality, regulatory compliance, and supply\u2011chain integrity. In every instance, Melanotan II must be employed strictly within the bounds of its intended laboratory research application, in accordance with all applicable laws and institutional policies.\n<\/p>\n \u00c0 usage exclusivement scientifique :<\/strong> This article describes Melanotan II exclusively as a research chemical for laboratory investigation.
