Ibutamoren

An orally active, non-peptide growth hormone secretagogue. It is not a peptide, but it is sold and discussed alongside them.

Ibutamoren is classified as a non-peptide ghrelin receptor agonist. Its current development status is: discontinued clinical development. Human trial data exists but is limited in size, duration or independence; conclusions should be held loosely.

The Peptide Institute tracks Ibutamoren because it is actively sold through research-compound and telehealth channels. Our interest is narrow and specific: what is actually in the vial, whether the label is accurate, and whether the sellers of it can document what they claim. We take no position on whether anyone should use it.
