Ibutamoren is a non-peptide ghrelin receptor agonist with a development status of "discontinued clinical development". The Institute rates the strength of its published evidence as moderate. An orally active, non-peptide growth hormone secretagogue. It is not a peptide, but it is sold and discussed alongside them.
Commercial availability of Ibutamoren continues to run ahead of its regulatory status. That is the recurring structural feature of this market: demand arrives when trial data is published, and supply arrives from channels that answer to nobody in particular.
Our position on developments like this is consistent. We report what changed, we test what is being sold, and we decline to speculate about what a regulator will do next.
The Institute has independently tested 1 Ibutamoren sample from 1 company. 100% met their label claims on purity and content. Measured purity ranged from 96.9% to 96.9%, averaging 96.9%. Every specimen is published in full, including the laboratory that ran it.
The Peptide Institute is an independent research institute. We do not sell products, we do not accept vendor sponsorship, and we publish results that reflect badly on companies as readily as results that do not.
