Results from this study2

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

Studies that did not test the peptide alone2

In this study, the peptide 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 the peptide.

  1. 01LabNot a test of GHRP-6 aloneIn vitro (cell-free)Other

    Solid-phase extraction protocols were confirmed effective by analysis of urine samples containing ipamorelin, and GHRP‑6 and its metabolites.
