Product Introduction & Core Mechanism
Melanotan 2 Acetate (MT-2) is a synthetic cyclic melanocortin peptide derived from natural alpha-melanocyte-stimulating hormone (α-MSH). It acts as a potent non-selective agonist targeting MC1R, MC3R, MC4R and MC5R melanocortin receptors, while avoiding activation of MC2R to prevent excess cortisol production. Its stable cyclic peptide structure delivers stronger receptor binding affinity and longer bioavailability than native α-MSH, widely applied in pigmentation, neuroendocrine and dermatology laboratory research.
Core research functions:
- Stimulate melanogenesis & boost skin pigmentation
Activates MC1R on melanocytes to upregulate tyrosinase, the key enzyme for melanin synthesis. It accelerates natural skin tanning without overexposure to UV radiation, commonly used for sunless pigmentation and UV photoprotection studies. - Neuroendocrine pathway research via MC4R activation
Modulates central nervous system melanocortin signaling to regulate libido, appetite and energy balance; extensively studied in reproductive physiology and metabolic appetite regulation models. - Anti-inflammatory & tissue protective effects
Suppresses pro-inflammatory cytokine release and reduces oxidative stress in skin and peripheral nerve tissue, applied in research on inflammatory skin lesions and nerve injury recovery. - UV damage defense research
Elevated melanin levels provide natural UV shielding capacity, reducing DNA photodamage caused by ultraviolet radiation in preclinical dermatology trials.
Our Melanotan 2 Acetate Product Competitive Advantages
- Ultra-high purity ≥99%
Every batch passes HPLC full purity testing and LC-MS mass spectrum identification. Complete COA, HPLC chromatogram, heavy metal and low-endotoxin test reports are provided for all bulk orders; no truncated peptide fragments or oxidation impurities. - Advanced vacuum freeze-drying technology
Full moisture removed without preservatives to lock complete peptide biological activity. Lyophilized solid powder resists hydrolysis and oxidation during long-distance cross-border air & sea shipping, maintaining stable potency with a 24-month shelf life under proper storage. - GMP clean-room sterile production
Individually sealed single vial packaging to avoid cross-contamination. Custom private labels, bottle sizes and bulk packing service available for global lab resellers and research suppliers. - Excellent water solubility
Rapidly dissolves in sterile bacteriostatic water to form clear, sediment-free transparent solution, ideal for precise low-dose preparation for in vitro and in vivo laboratory experiments. - Complete professional technical support
We supply detailed reconstitution guide, temperature storage rules, laboratory dosage reference data and full batch traceability documents for all distributors.
Storage & Reconstitution Instructions
- Unopened lyophilized powder: Long-term storage at -20°C away from light and humidity, shelf life up to 24 months; short transit storage at 2–8°C is acceptable.
- Recommended solvent: Sterile bacteriostatic water
- Operation tip: Let the vial equilibrate to room temperature before opening; slowly inject solvent along the inner vial wall and swirl gently. Violent shaking triggers peptide aggregation and irreversible activity loss.
- Reconstituted liquid: Seal tightly and refrigerate at 2–8°C, finish all usage within 14 days; avoid repeated freeze-thaw cycles.
Global Wholesale Cooperation Support
- Flexible minimum order quantity & tiered large-volume discount for stable VIP long-term partners
- Low-risk dedicated shipping lines for USA, EU, Brazil, Australia with reduced customs detention probability
- Exclusive one-on-one VIP account manager, fast working-hour response and professional reshipping solutions for logistics issues
