Research Benefits

  • Melanocortin System Research — Melanotan II (MT-II) is a non-selective melanocortin receptor agonist (MC1R-MC5R), making it a versatile tool for studying the full melanocortin system.
  • Melanogenesis Studies — MT-II induces eumelanin production via MC1R activation, enabling research into UV photoprotection and pigmentation biology.
  • Appetite Regulation — MC4R agonism by MT-II reduces food intake in animal models, supporting research into melanocortin-mediated energy homeostasis.
  • Behavioral Neuroscience — MT-II's effects on multiple MCRs provide a broad-spectrum tool for studying melanocortin involvement in social behavior, arousal, and stress responses.

Mechanism of Action

Melanotan II is a synthetic cyclic heptapeptide analog of α-MSH. It is a non-selective agonist at melanocortin receptors MC1R through MC5R.

MC1R (Melanogenesis): Activation stimulates adenylyl cyclase, increasing cAMP and activating MITF transcription factor, which upregulates tyrosinase and melanin synthesis in melanocytes.

MC3R/MC4R (Behavioral/Metabolic): Central agonism reduces appetite (MC4R), modulates sexual behavior (MC3R/MC4R), and influences stress responses through hypothalamic signaling.

MC5R (Exocrine): Activation modulates exocrine gland secretion, including sebaceous gland activity.

Cyclic Structure: The lactam bridge between residues confers proteolytic resistance and enhanced receptor binding affinity compared to linear α-MSH.

Research Protocol

Derived from published research. For research use only.

Reconstitution

Reconstitute in bacteriostatic water. Stock: 1-2 mg/mL.

Research Dosing (from published studies)

  • In vivo (murine, melanogenesis): 0.5-1.0 mg/kg SC daily for 7-14 days.
  • In vivo (feeding studies): 1-10 nmol ICV for acute anorectic response.
  • In vitro: 10 nM - 10 μM for melanocyte stimulation and cAMP assays.

Storage

Lyophilized at -20°C. Reconstituted at 2-8°C, use within 21 days.

Safety & Handling

Research Use Only.

Storage Conditions

  • Lyophilized: -20°C, protected from light
  • Reconstituted: 2-8°C, 21 days

Known Considerations from Literature

  • MT-II's non-selective receptor profile produces multiple concurrent effects (pigmentation, appetite suppression, behavioral changes) that complicate single-pathway studies.
  • Nausea and facial flushing are commonly reported in research settings at higher doses.
  • Potential for melanocyte activation warrants monitoring for atypical pigmentation in chronic studies.
  • MC4R agonism may affect cardiovascular parameters (blood pressure, heart rate).

Handling

Standard PPE. Protect from light during handling and storage.

Frequently Asked Questions

What is Melanotan II?
Melanotan II is a synthetic cyclic heptapeptide that acts as a non-selective agonist at all five melanocortin receptors (MC1R-MC5R). It was originally developed for melanogenesis and photoprotection research.
How does MT-II differ from MT-I?
MT-I (Afamelanotide) is a linear peptide that is relatively selective for MC1R (melanogenesis). MT-II is a cyclic peptide with activity across all MCRs, producing broader effects including appetite, behavioral, and pigmentation changes.
Why is MT-II light-sensitive?
The peptide contains aromatic amino acid residues susceptible to photo-oxidation. Store protected from light and reconstitute in amber vials when possible.
What purity is this product?
BeaCapra Melanotan II is ≥99% pure by HPLC with full COA.

Great product, COA checks out

Ran our own HPLC analysis and confirmed the purity claims. Packaging was secure and discreet. Only minor note — would love to see more size options for some of the newer compounds. Otherwise excellent.

Product FAQ

Questions About MT-2 Melanotan II

Melanotan-1 (afamelanotide) is a linear analog of α-MSH with selective MC1R affinity. Melanotan-2 is a cyclic analog with broader melanocortin receptor activity (MC1R, MC3R, MC4R, MC5R). Published research shows different pharmacological profiles and research applications.
All BeaCapra peptides are independently verified to 99%+ purity via HPLC. The batch-specific Certificate of Analysis is available on this page and ships with your order.
Store lyophilized peptides at -20°C or lower for long-term storage. For short-term use, 2–8°C (refrigerator) is acceptable. Once reconstituted, store at 2–8°C and use within the timeframe on the product documentation. Avoid repeated freeze-thaw cycles.
