The Melanotan II market in 2026: who is actually selling it

A close reading of the Melanotan II evidence, without the marketing layer.

The Melanotan II market in 2026: who is actually selling it

Melanotan II is a non-selective melanocortin agonist with a development status of "never approved; research use only". The Institute rates the strength of its published evidence as limited. A non-selective melanocortin agonist that drives melanogenesis, with a well-documented adverse-effect profile and no approval anywhere.

Commercial availability of Melanotan II continues to run ahead of its regulatory status. That is the recurring structural feature of this market: demand arrives when trial data is published, and supply arrives from channels that answer to nobody in particular.

Our position on developments like this is consistent. We report what changed, we test what is being sold, and we decline to speculate about what a regulator will do next.

The Institute has independently tested 3 Melanotan II samples from 2 companies. 100% met their label claims on purity and content. Measured purity ranged from 97% to 97.6%, averaging 97.3%. Every specimen is published in full, including the laboratory that ran it.

The Peptide Institute is an independent research institute. We do not sell products, we do not accept vendor sponsorship, and we publish results that reflect badly on companies as readily as results that do not.
