MT1 — Research Peptide (Melanotan 1) Melanotan 1 (MT-1) is a lab-made version of the natural hormone α-melanocyte stimulating hormone (α-MSH). Melanotan 1 is a synthetic linear α-melanocyte-stimulating hormone (α-MSH) analog (Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH₂) designed to study melanocortin receptor activation, particularly MC1R. It activates cAMP-dependent signaling cascades involved in pigmentation and photoprotective pathways in vitro. Melanotan I is widely used in receptor pharmacology and cell signaling research investigating peptide–GPCR interactions and transcriptional regulation.
Key Details:
Our MT1 5mg is a synthetic peptide that mimics the action of the natural hormone alpha-melanocyte stimulating hormone (α-MSH). It is designed to stimulate the production of melanin in the skin, leading to a darker and more even tan.
Key components and functions:
MT1 activates the melanocortin-1 receptor, leading to increased production of eumelanin, the pigment responsible for skin darkening. This process occurs without the need for prolonged sun exposure, reducing the risk of skin damage.
Common benefits:
MT1 5mg is commonly used for sunless tanning, reducing the risk of sunburn, and as a treatment for individuals with skin conditions that result in depigmentation, such as vitiligo. Additionally, some users report a decrease in appetite and an increase in libido as secondary benefits.
Regulatory and use: Our MT1 5mg is for research use only and is not intended for human consumption. It should be handled with care and stored according to the instructions provided. This peptide should only be used by individuals with an in-depth understanding of peptides and their potential effects.
