A cyclic analogue of α-MSH, often confused with afamelanotide and PT-141, whose evidence does not carry over to it. MT-2 is not approved, and its human record is three small early studies from one group, 1996–2000.

What MT-2 does
MT-2 is a ring-closed copy of the body's alpha-MSH signal that activates the melanocortin receptors broadly rather than selectively. Its human record is three small studies from one University of Arizona group between 1996 and 2000: a three-person phase I study in which 2 of 3 volunteers showed increased pigmentation, and two ten-man double-blind placebo-controlled crossover studies in men with erectile dysfunction, where mean tip rigidity above 80% lasted 38.0 minutes against 3.0 on vehicle in one and 45.3 against 1.9 in the other, with higher self-rated sexual desire in the later study. Its appetite and body-composition effects were measured in rats given the peptide directly into the brain, where it cut caloric intake and produced fat-mass loss that pair-feeding did not reproduce. Nausea, a stretching-and-yawning complex and reduced appetite were more frequent after MT-2 than after placebo in those crossover studies, and what has been published since is largely case reports from unregulated use: melanoma, atypical and eruptive moles, rhabdomyolysis with renal injury, renal infarction, priapism and posterior reversible encephalopathy. Vials sold online have been assayed at 43% to 88% of their labelled peptide content, with vials from two of the three shops also carrying unidentified impurities.

Common areas of interest, not measured results. The findings below are the published data.
In a 1996 single-blind, alternating-day, placebo-controlled pilot phase I study in 3 healthy male volunteers, 2 of the 3 had increased pigmentation of the face, upper body and buttock on both quantitative reflectance and visual assessment, measured one week after two weeks of subcutaneous dosing ended.2
In a 2026 single-patient case report with three months of follow-up, a person who self-injected MT-2 over a 64-day period for tanning had brown pigmentation on the attached gingiva of both arches and on both buccal mucosae; one month after stopping, the buccal pigmentation had nearly disappeared, while at three months the gingival pigmentation persisted at reduced intensity.9
In a 1998 double-blind, placebo-controlled crossover study in 10 men with erectile dysfunction of no known organic cause, RigiScan monitoring across a 6-hour window recorded mean tip rigidity above 80 percent lasting 38.0 minutes after MT-2 versus 3.0 minutes after vehicle placebo (p=0.0045); clinically apparent erections developed in 8 of the 10 men.3
