Melanotan 2 (MT2) is a synthetic cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone (α-MSH). It is supplied as a lyophilised research material for controlled studies of melanocortin-receptor activity, receptor selectivity and pigmentation signalling.
Research material only
This material is not supplied as an authorised medicine, treatment, cosmetic, tanning product, supplement or consumer product. It is not for human or veterinary use, consumption or administration, and is not intended to diagnose, treat, cure or prevent any disease.
Compound overview
Research context
Melanotan 2 is a lactam-bridged cyclic analogue derived from the central melanocortin sequence of α-MSH. Published studies commonly describe it as a potent, non-selective melanocortin-receptor agonist and have examined receptor binding, cyclic-AMP-associated signalling and pigmentation responses in experimental models.
Research has also used MT2 to investigate other melanocortin receptor subtypes and biological systems. Those observations reflect the particular materials, doses and experimental conditions used by the cited authors. They do not establish the identity, purity, performance or suitability of the material supplied on this page and must not be interpreted as consumer or clinical claims.
Batch documentation
Independent analytical documentation is published where available for specific batches and variations. A result indicator appears only when a published record is available. Match the product, stated mass and batch identifier to the corresponding report before relying on any result.

Supply and laboratory handling
- Supplied in the vial size selected above.
- Keep the sealed lyophilised vial dry and protected from direct light.
- A cool, dry place, refrigerator or freezer may be used according to the intended storage duration and your laboratory’s validated procedure.
- Use clean laboratory technique and equipment appropriate to the intended analytical method.
- Follow the lot-specific documentation and your laboratory’s validated handling and storage procedures.
- Avoid repeated temperature cycling and unnecessary exposure to moisture.
Where a batch document or supplier specification gives different instructions, the lot-specific document takes precedence.
Frequently asked questions
What is Melanotan 2?
Melanotan 2 is a synthetic lactam-bridged cyclic heptapeptide derived from an α-MSH sequence. It is studied as a non-selective melanocortin-receptor agonist in receptor-signalling and pigmentation models.
Is Melanotan 2 the same as Melanotan 1?
No. Melanotan 2 is a cyclic heptapeptide with broader melanocortin-receptor activity. Melanotan 1, also known as afamelanotide, is a different linear 13-amino-acid analogue.
Is this product an authorised medicine or tanning product?
No. It is supplied only as a laboratory research material and is not an authorised medicine, cosmetic or tanning product. It is not for human or veterinary use, consumption or administration.
Which vial sizes are available?
Current vial sizes, stock, pre-order status, pricing and any batch-documentation indicators are shown in the variation selector above.
Does every vial size have a published laboratory result?
No. Results are available only for the selected batches and variations marked with a result indicator. Always check that the product, stated mass and batch identifier match the report.
How should the material be stored?
Keep the sealed lyophilised material dry and protected from light. A cool, dry place, refrigerator or freezer may be used according to the intended storage duration and your laboratory’s validated procedure. Avoid repeated temperature cycling and moisture exposure. No universal shelf-life is stated unless it is supported by batch documentation.
