Description
Melanotan II 10mg is a 10mg vial of Melanotan II, a cyclic melanocortin agonist, supplied by Blue Sky Peptide as freeze-dried powder. This batch tested at 99.51% purity. It’s for in-vitro and lab research only.
About Melanotan II
Melanotan 2 (Melanotan II) is a cyclic seven-amino-acid peptide based on alpha-melanocyte stimulating hormone. A ring structure makes it far more stable than the natural hormone.
It acts on several melanocortin receptors at once, MC1R through MC5R. MC1R controls skin pigment, which is why it’s studied for tanning, and its effects on MC4R led to the development of PT-141.
How Melanotan II works
Melanotan 2 activates MC1R on pigment cells, which drives eumelanin production and darker pigmentation. Unlike Melanotan 1, it also acts strongly on MC3R and MC4R in the brain.
That brain activity explains the effects on appetite and sexual function seen in early studies, and it’s the reason PT-141 was developed from it.

Melanotan II research
It was developed at the University of Arizona in the late 1980s and 90s, by a team including Mac Hadley and Victor Hruby, as a way to tan skin without UV exposure. Early human studies confirmed the tanning effect.
It was never approved, and several health agencies have warned against unlicensed use. It’s sold here strictly for research.

How Melanotan II compares
Labs choosing Melanotan II 10mg usually weigh it against a few close relatives. Melanotan II is a cyclic alpha-MSH analog that drives melanin production, while:
- GHK-Cu is the copper-binding tripeptide studied for collagen and skin repair
- SNAP-8 is an eight-amino-acid cosmetic peptide studied for expression lines
- Glutathione is the cell’s main antioxidant tripeptide
These cover the three main lines of skin research: repair and collagen, expression lines and pigmentation. See them all on our skin and tanning peptides page.
How to reconstitute Melanotan II 10mg
Concentration is the amount in the vial divided by the liquid you add. With 10mg in this vial:
- 1mL of water gives 10mg/mL
- 2mL of water gives 5mg/mL
- 3mL of water gives 3.33mg/mL
Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.
Use sterile bacteriostatic water. Warm the sealed vial to room temperature first so no condensation gets in, add the water slowly along the glass wall, and swirl gently until it’s clear. Never shake it.
Melanotan II 10mg storage and shelf life
The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.
A 10-slot vial case keeps open and sealed vials upright and apart, which makes the fridge shelf a lot easier to manage. For transport, the Blue Sky hard storage box is the sturdier option.
Melanotan II 10mg quality and batch records
Purity for this batch of Melanotan II 10mg came back at 99.51% by HPLC and mass spectrometry. That’s the figure for the batch currently in stock.
Note the batch number on the label when the vial arrives. That’s what the certificate of analysis is filed under, and we’ll send you a copy on request.
If a result looks off, check the batch number first, then your handling notes. Most problems with Melanotan II come from storage or mixing, not the material.
