Melanotan-2
Melanotan-2 (MT-2) is a cyclic heptapeptide analogue of alpha-melanocyte-stimulating hormone.odisiac/libido effects. It is one of the few research peptides where the legal status in the EU has been explicitly addressed in multiple countries — and it is not always the same answer.
Potency loss over time
Estimated potency retained (%) per storage condition. Hover the chart for details.
⚠ Computed from molecular properties (sequence length, cyclisation, residues prone to oxidation or deamidation, light sensitivity), per compound. Indicative only — not lab-measured per batch.
Time in body
How much of a single dose remains over time, modelled from the terminal half-life. Illustrative — not a dosing tool.
Half-life ~45 min (literature estimate) · effectively cleared (~97%) after ~3.8 h (5 half-lives).
