Short answer
What is Melanotan 2?
Melanotan 2 (melanotan II) is a synthetic cyclic 7-amino-acid analogue of alpha-melanocyte-stimulating hormone that binds melanocortin receptors.
It also appears in the literature as Melanotan-II, MT-II, Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-NH2.
What is in each Melanotan 2 vial?
| STRENGTH | FORM | PRICE | CERTIFICATE |
|---|---|---|---|
| 10mg | Lyophilised powder | A$68 | Pending |
What has research on Melanotan 2 examined?
Melanotan II was studied in small early-phase human trials in the 1990s (skin pigmentation and erectile responses) and in animal models. It has not been approved as a medicine, and recent literature includes case reports of adverse events from unregulated use.
The table lists primary sources by year and model. Findings describe the study subjects, not this research vial.
What adverse events have studies of Melanotan 2 reported?
In a small placebo-controlled crossover study in 20 men with erectile dysfunction, nausea and yawning were frequent, with severe nausea in 12.9% at 0.025 mg/kg (PMID 11035391). Case reports of unlicensed 'melanotan' injection describe acute priapism (PMID 30796078) and melanoma in situ (PMID 22724573).
These findings describe the people or animals in each study. The sources list gives every PubMed record.
How do you reconstitute and store Melanotan 2?
Store the sealed vial frozen (about -20 degrees Celsius), dry and away from light until it is reconstituted.
After reconstitution with a sterile solvent, keep the solution at 2 to 8 degrees Celsius and avoid repeated freezing and thawing. Record the solvent, volume and date on the vial label.
BAC Water is the usual laboratory solvent. Dilute acetic acid is an alternative for peptides that dissolve poorly in water. The reconstitution guide and storage guide cover laboratory handling.
| STATE | TEMPERATURE | NOTES |
|---|---|---|
| Sealed vial | -20 °C | Dry and dark. Keeps to the label date. |
| Reconstituted | 2 to 8 °C | Sterile technique. Avoid repeat freeze and thaw. |
| In transit | Cold pack | Refrigerate or freeze on arrival. |

Case reports of unlicensed 'melanotan' injection describe acute priapism (PMID 30796078) and melanoma in situ (PMID 22724573).
Is melanotan 2 a peptide?
Yes. Melanotan 2 is a peptide of 7 amino acids.
Is melanotan 2 a prescription medicine in Australia?
Melanotan II is listed in Schedule 4 of the Poisons Standard (prescription only). Peptides Collective sells it for laboratory research use only.
Is melanotan 2 banned in sport?
Melanotan 2 is not named on WADA's 2026 Prohibited List. WADA's S0 class covers any substance without government approval for human use, so Sport Integrity Australia is the body to confirm its status.
What is the CAS number for melanotan 2?
The CAS number for Melanotan 2 is 121062-08-6. Its PubChem CID is 92432.
How long does an unopened melanotan 2 vial keep?
A sealed vial of lyophilised powder keeps to the date on its label when stored frozen, dry and dark. Once reconstituted, keep the solution at 2 to 8 degrees Celsius and record the date on the label.
Does every melanotan 2 batch have a certificate?
Yes. Every Melanotan 2 batch is tested by [lab] before it goes on sale, and the certificate is published under the batch number printed on the vial. The current batch certificate is [pending].
