Ipamorelin is a ghrelin receptor agonist (gh secretagogue) with a development status of "discontinued clinical development". The Institute rates the strength of its published evidence as emerging. A selective growth-hormone secretagogue studied for GH release with minimal effect on cortisol and prolactin.
Commercial availability of Ipamorelin 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.
The practical consequence for buyers is that a headline about promising results tends to be followed within weeks by a wave of new sellers, and the quality of that wave is not correlated with the quality of the science that prompted it.
The Institute has independently tested 7 Ipamorelin samples from 5 companies. 100% met their label claims on purity and content. Measured purity ranged from 94.2% to 99.2%, averaging 97.5%. 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.
