About this lot
What you receive
Melanotan II (MT-2) is a synthetic analogue of the naturally occurring alpha-melanocyte-stimulating hormone (α-MSH). Lyophilised powder, ≥98% HPLC, full third-party CoA supplied.
Melanotan II (MT-2) is a synthetic cyclic heptapeptide analogue of the endogenous α-melanocyte stimulating hormone (α-MSH), studied as a non-selective melanocortin receptor agonist in melanogenesis, pigmentation, MC1R/MC4R signalling and appetite-pathway research. UK Peptides supplies MT-2 10mg lyophilised powder at ≥98% HPLC-UV verified purity with a third-party Certificate of Analysis on every batch.
Melanotan II is a synthetic cyclic analogue of α-MSH developed at the University of Arizona in the 1980s as a more stable, longer-acting research tool for studying the melanocortin receptor system. The peptide acts as a non-selective agonist at MC1R, MC3R, MC4R and MC5R receptors, making it one of the most useful reference compounds for exploring the entire melanocortin signalling network in cell-based and animal-model research.
MC1R agonism drives melanogenesis in melanocytes through cAMP-mediated upregulation of tyrosinase and downstream eumelanin synthesis — the basis of MT-2's well-documented pigmentation effects in research models. MC4R agonism is implicated in central appetite regulation and sexual function research, while MC3R and MC5R agonism are studied in inflammatory and exocrine pathway research. The cyclic structure of MT-2 confers metabolic stability significantly greater than native α-MSH, enabling longer-duration research protocols.
The 10mg vial holds enough material for multi-week experiments at standard reconstitution concentrations. Published research covers:
Store the lyophilised vial at -20°C, sealed and protected from light. Reconstitute with bacteriostatic water (0.9% benzyl alcohol) — typically 1ml or 2ml per 10mg vial. Add solvent down the inside wall of the vial slowly; do not shake. Refrigerate the reconstituted solution at 2–8°C and use within 28 days. Do not refreeze.
Every MT-2 10mg vial is independently tested by Janoshik Analytical or Aspen Bioanalytics to ≥98% HPLC-UV purity with mass-spectrometry identity confirmation against the published molecular weight of 1,024.18 Da. The signed PDF CoA is supplied with every order and matches the vial lot number.
Melanotan II is one of the longest-established research peptides on the grey market, which means counterfeit and under-dosed product is unusually widespread. UK Peptides counters this with mandatory third-party HPLC verification on every batch, UK-stocked inventory, same-day Manchester dispatch and full lot traceability — visible directly on this product page.

Melanotan II (MT-II) is a synthetic cyclic heptapeptide analogue of α-melanocyte-stimulating hormone (α-MSH), first synthesised at the University of Arizona by Hruby and colleagues in the 1980s. It acts as a non-selective agonist at melanocortin receptors MC1R, MC3R, MC4R and MC5R. The UK Medicines and Healthcare products Regulatory Agency has repeatedly warned that unlicensed melanotan products are not authorised for human use.

"Ordered Melanotan II 10mg on behalf of a university research group. Invoicing was clean, the CoA was acceptable to our procurement team without amendment, and the vial passed our internal QC on first inspection."
Dr. K. Sandhu · 2025-05-22
"The vial of Melanotan II 10mg arrived intact, lot number matched the CoA, and reconstitution behaved exactly as expected. The whole experience felt closer to a pharmaceutical supplier than a research-chemical one."
J. Harkness · 2025-05-15
"Honestly the most professional UK peptide source I have used in six years of lab work. The Melanotan II 10mg batch was clean, documentation thorough, and customer service answered an analytical question within hours."
R. Beaumont · 2025-05-08
"Verified the Melanotan II 10mg lot against an external reference standard — identity and purity both within published spec. Same-day dispatch from Manchester, well-packed, no transit damage. Will be reordering."
Dr. S. El-Hadid · 2025-05-01
"Ordering Melanotan II 10mg from UK Peptides is now a routine line item in our monthly research budget. Predictable quality, predictable delivery, predictable documentation. That is exactly what a working lab needs."
T. Vasquez · 2025-04-24
"Good purity on the Melanotan II 10mg lot, fast dispatch, well-packed. Only suggestion would be a slightly larger ice pack for warmer weather deliveries — vial itself was fine either way."
