Ipamorelin: A Selective Secretagogue With Modest but Consistent Data
Ipamorelin is the most searched growth-category peptide in our library, largely because it is described as selective. That selectivity claim is worth examining rather than assuming.

What selectivity means here
Ipamorelin is a pentapeptide ghrelin-receptor agonist studied for growth hormone release with comparatively little effect on cortisol and prolactin in early studies — the basis of the selectivity claim.
Our index tracks around 88 referencing studies. The signal is consistent but the human dataset is small, so we grade the evidence as Moderate.
Why it is usually discussed alongside CJC-1295
Secretagogues and GHRH analogues act through different receptors, which is why research protocols frequently pair them. Vendors market the combination heavily; the underlying combination research is thinner than the marketing suggests.
Pricing
5mg vials typically run £12 to £22, making ipamorelin one of the cheaper compounds we track. Low cost also means low margin for third-party testing, so certificate coverage is patchier in this category than in metabolic peptides.
What to verify
Check for a batch-matched HPLC result and confirm the mass spectrometry figure matches the expected molecular weight for the pentapeptide sequence.
Vendors that test cheap products as thoroughly as expensive ones are, in our experience, the most reliable across the whole catalogue.
Frequently asked
How strong is the human evidence?
Limited. Early human studies are consistent with the mechanism, but the controlled outcome data is small in scale.
Does the low price mean low quality?
Not automatically, but cheap products are tested less often. Judge the certificate, not the price.
