How to Buy Melanotan I

Melanotan I (MT1) is a synthetic analogue of the melanocyte-stimulating hormone (α-MSH) studied for its effects on skin pigmentation and photoprotection.

Unlike Melanotan II, MT1 is selective for the MC1R receptor, which means it primarily affects melanin production without the broader pharmacological effects associated with MT2.

At Omrena, Melanotan I is available in 10 mg and 50 mg lyophilised vials.

Melanotan I acts through a single, specific receptor:

→MC1R activation — selectively stimulates melanin synthesis in melanocytes, promoting skin pigmentation independently of UV exposure.

→Photoprotection — the increased melanin production has been shown in clinical studies to provide a degree of natural protection against UV-induced skin damage.

This receptor selectivity makes MT1 a cleaner model for studying pigmentation biology than the multi-receptor MT2.

Every Melanotan I batch is independently tested for purity (≥99% HPLC) and shipped lyophilised in sealed vials.
