Melanotan II price comparison

Melanotan II (MT-2) is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). In laboratory research it is described as a non-selective agonist studied at melanocortin receptors. It is one of the most-searched non-GLP research peptides and is supplied strictly for research use only, not for human or veterinary use. This index tracks per-milligram pricing for Melanotan II across research-use-only (RUO) vendors.

▸ Why compare $/mg for Melanotan II?

Per-mg prices for Melanotan II vary widely because vendors differ in synthesis scale, stated HPLC purity, vial fill size (commonly 10 mg), and how testing and shipping overhead are amortized into the unit price. Comparing normalized $/mg across vendors lets a researcher weigh cost against documented purity rather than headline vial prices.

▸ Reading the COA

For Melanotan II, confirm identity by mass spectrometry against the expected monoisotopic mass (~1024 Da for the cyclic heptapeptide, C50H69N15O9) and check that HPLC purity is reported at 98%+ with a dated, batch-specific chromatogram. Watch for linear (non-cyclized) precursor, deletion/truncation sequences, and acetate/TFA counter-ion content that can inflate net peptide mass; the COA lot number should match the vial label. A COA verifies the identity and purity of the material, not any biological outcome.

▸ FAQ

How should lyophilized Melanotan II be stored in a lab setting?
As a lyophilized powder, Melanotan II is generally stored sealed and protected from light, moisture, and heat, and is typically kept frozen for longer-term storage per the vendor's stated conditions. In solution, peptides of this type are generally less stable than the dry powder and degrade faster; researchers should follow the supplier's documented storage guidance for the specific lot. This is storage information for research material only and is not human-use guidance.
What is a COA and what should I check for on a Melanotan II certificate?
A Certificate of Analysis (COA) is a batch-specific document reporting the analytical testing done on a given lot. For Melanotan II, verify the lot number matches the vial, that identity is confirmed by mass spectrometry against the expected mass, and that HPLC purity (typically 98%+) is shown with a dated chromatogram. A COA verifies the identity and purity of the material, not any biological outcome.
Why do per-mg prices for Melanotan II differ so much between vendors?
Differences come from synthesis and purification scale, stated purity grade, vial fill size, counter-ion content affecting net peptide mass, and whether third-party testing and shipping are bundled into the unit cost. Normalizing to $/mg makes these otherwise hidden differences comparable across research-use-only suppliers.
