Results from this study3

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone3

In this study, Melanotan II was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Melanotan II.

    Summary · context
    A solid-phase extraction (SPE) method has been developed for the isolation of melanotan II from rabbit urine.

    In this study, Melanotan II was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Melanotan II.

    The HPLC method for melanotan II in rabbit urine had a relative standard deviation below 5% for between-day and same-day analyses.

    In plain wordsIn lab tests, the melanotan II assay in rabbit urine gave very similar results from day to day and within one day.
