What is Melanotan-2?
Melanotan-2 is a cyclic lactam analogue of alpha-melanocyte-stimulating hormone that binds several melanocortin receptors rather than one. That lack of selectivity is precisely why it is used in receptor-mapping research, and why its effects are harder to attribute to a single receptor. Pepstral supplies it as a lyophilized powder for in-vitro laboratory research only.
What is Melanotan-2 studied for?
- Melanocortin receptor selectivity mapping
- MC1R, MC3R and MC4R binding assays
- Pigmentation research
- Comparisons against selective analogues
All applications above are in-vitro or preclinical research contexts. Melanotan-2 is sold for laboratory research only and is not for human or animal use.
What does the certificate for lot MEL-2609-Y show?
Every lot of Melanotan-2 is tested by an independent US laboratory before it is listed. The report for lot MEL-2609-Y is in the COA library and the lot number printed on the vial matches it. The current results:
| Test | Method | Lot MEL-2609-Y result |
|---|---|---|
| Identity | LC-MS | Matches the calculated mass for the sequence |
| Purity | HPLC-UV, 220 nm | 99.0% |
| Net peptide content | Amino acid analysis | Stated per vial on the certificate |
| Endotoxin | LAL, chromogenic | < 0.5 EU/mg |
| Sterility | USP <71> | Pass |
How is Melanotan-2 handled and stored?
Sealed vials are stored at -20°C away from light and keep for 24 months. To reconstitute, add bacteriostatic water slowly down the inside wall of the vial and swirl until clear; never shake. Once in solution, keep at 2 to 8°C and use within the 28-day window on the certificate. The reconstitution guide covers volumes and syringe units and the concentration table gives the numbers for this vial.
Frequently asked questions
Why is melanotan-2 non-selective?
The cyclic lactam structure retains affinity across several melanocortin receptors instead of narrowing to MC1R.
Which receptors does it engage?
It is described as active at MC1R, MC3R, MC4R and MC5R, which is why an observed effect cannot be attributed to one receptor without controls.
Is Melanotan-2 for human use?
No. Every product on this site is sold for in-vitro laboratory research only and is not for human or animal consumption, diagnostic or therapeutic use.
