Melanotan I （10mg10vials）

Melanotan I (also known as MT-1 or afamelanotide) is a synthetic 13-amino-acid peptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It binds primarily to the melanocortin-1 receptor (MC1R) to stimulate the production of eumelanin, the dark pigment in human skin.

Approved Drug vs. Gray-Market Product

• Approved Medication (Afamelanotide / Scenesse): The exact same molecule is FDA-approved as a controlled-release subcutaneous implant called Scenesse. It is strictly prescribed and administered under medical supervision for erythropoietic protoporphyria (EPP), a rare genetic disorder that causes severe, painful light and sun sensitivity.

• Gray-Market / Research Tanning Peptides: "Melanotan I" is frequently sold online as an unregulated, self-injected powder or "research chemical" marketed for cosmetic tanning. These gray-market vials are not FDA-approved as tanning products, lack quality control, and do not carry the safety, sterility, or purity assurance of regulated pharmaceuticals.

How It Works

• Receptor Selectivity: MT-1 is more selective for the MC1R pigment receptor than Melanotan II, meaning it focuses more heavily on melanin production and typically has a narrower range of systemic side effects than its broader counterpart.

• Eumelanin Production: It triggers the skin to synthesize eumelanin, which provides a degree of natural photoprotection against ultraviolet (UV) radiation.

Risks and Side Effects

• Common Side Effects: Nausea, gastrointestinal upset, fatigue, dizziness, headaches, and facial flushing.

• Skin and Cancer Risks: Unregulated tanning peptides accelerate the darkening, growth, and appearance of moles and sunspots. This can make it difficult for dermatologists or individuals to spot early signs of melanoma or other skin cancers.
