His eyes are still blue. That’s the first thing you notice. Everything else changed.

This man, identified on forums as a chronic Melanotan II user, documented for years the cumulative effect of injecting himself with a synthetic hormone analogous to melanocortin, a substance not approved by any health agency and obtained through gray markets on the internet. The drug stimulates the production of melanin in the skin. The visible result in the photos: a dark, even, and progressive pigmentation that irreversibly transformed his skin tone. In his latest entry, he noted “30 years old” and “47 mg” in front of the camera, as if he were keeping a clinical diary of his own experiment.

What is most unsettling is not the change itself, but that he did it deliberately, consistently, and in a documented way. Doctors who have analyzed similar cases warn that Melanotan II can also activate moles, accelerate the growth of melanomas, and alter the endocrine system. But he kept going. The photos speak for themselves.
