α-MSH is a peptide hormone known for its high affinity for the melanocortin-1 receptor (MC1R), a receptor that plays an essential role in determining pigment production in biological systems. In addition to MC1R, α-MSH interacts with melanocortin receptors MC3R, MC4R, and MC5R, contributing to a wide spectrum of physiological effects. MT-1 was engineered to improve the stability and receptor-selectivity profile of α-MSH. With one amino acid substitution, MT-1 maintains strong binding to MC1R, which makes it especially valuable in pigmentation-centered research models. Its improved resistance to degradation also supports studies requiring peptide stability over extended observation periods.
In laboratory research models, Melanotan-1 is used to investigate melanocortin receptor activity and intracellular signaling pathways associated with pigment cell regulation. Experimental studies examine how receptor activation influences cellular signaling responses in controlled research environments.

Licensed Peptides provides research-grade MT-1 with strict adherence to quality, purity, and handling standards. Our MT-1 (10 mg) undergoes controlled manufacturing and packaging processes to ensure the consistency required for credible laboratory work.
Key reasons research facilities prefer Licensed Peptides include:
Important: MT-1 from Licensed Peptides is intended for laboratory research only. It is not a drug, cosmetic ingredient, therapeutic substance, or product for human or animal use.
(For Research Purposes Only – Not for Human or Animal Use)
MT-1 is examined in studies involving melanogenesis, ultraviolet response, pigmentation pathways, and cellular photobiology.
MT-1 is studied primarily for targeted pigmentation effects, while MT-2 is associated with broader systemic receptor interactions. MT-1 research typically focuses on MC1R-driven pathways.
MT-1 should be stored in a cool, dark environment. For extended periods, freezing is commonly recommended to maintain peptide stability for research analysis.
Some laboratories examine interactions between multiple peptides, but MT-1 is frequently studied independently to isolate effects and maintain data clarity.
An LPS-free peptide indicates that the MT-1 has been processed to minimize lipopolysaccharide contamination, which is critical for laboratory experiments where endotoxins could interfere with cellular signaling, receptor assays, or biochemical readouts.
An endotoxin-free peptide helps ensure that experimental observations are attributable to MT-1 itself rather than confounding inflammatory or stress responses caused by endotoxin contamination, particularly in sensitive in-vitro research systems.
Yes. Research-grade MT-1 is supplied as a research peptide endotoxin tested, providing additional confidence in its suitability for controlled laboratory studies requiring strict quality and purity standards.

Storage Instructions:
All of our products are manufactured using the Lyophilization (Freeze Drying) process, which ensures that our products remain 100% stable for shipping for up to 3-4 months.
Once the peptides are reconstituted (mixed with bacteriostatic water), they must be stored in the fridge to maintain stability. After reconstitution, the peptides will remain stable for up to 30 days.
Lyophilization is a unique dehydration process, also known as cryodesiccation, where the peptides are frozen and then subjected to low pressure. This causes the water in the peptide vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure known as lyophilized peptide. The puffy white powder can be stored at room temperature until you’re ready to reconstitute it with bacteriostatic water.
Once peptides have been received, it is imperative that they are kept cold and away from light. If the peptides will be used immediately, or in the next several days, weeks or months, short-term refrigeration under 4C (39F) is generally acceptable. Lyophilized peptides are usually stable at room temperatures for several weeks or more, so if they will be utilized within weeks or months such storage is typically adequate.
However, for longer term storage (several months to years) it is more preferable to store peptides in a freezer at -80C (-112F). When storing peptides for months or even years, freezing is optimal in order to preserve the peptide’s stability.
