British Dragon Ipamorelin is a lyophilized pentapeptide presented at 5 mg per vial for laboratory research. It is a selective agonist at the ghrelin receptor, GHS-R1a, and published work uses it as a reference compound in growth hormone release assays because it activates that receptor with little effect on cortisol or prolactin. Buy ipamorelin as a sealed vial for reconstitution, or compare it with the other GHRP and GHRH standards in the catalogue before a study is designed.
Ipamorelin binds the ghrelin receptor on pituitary somatotrophs and triggers the same signalling cascade the body's own ghrelin uses, which is why it is grouped with the growth hormone secretagogues rather than the GHRH analogues. The peptide is short, so its active window in plasma is measured in hours rather than days, and that is why published protocols use it for pulsatile release models instead of steady-state work. Selectivity is the property most often tested. The Axiolabs Ipamorelin and Generic Peptides Ipamorelin pages describe the same molecule from other suppliers.
The vial ships as a lyophilized cake and is reconstituted with bacteriostatic water, added gently against the glass wall so the peptide is not denatured by shearing. Working solutions are kept cold, while unopened vials stay at room temperature away from light, with 2 to 8 degrees or lower as the reference practice. A GHRH-class standard for pituitary work is Sermorelin, and the longer-acting analogue CJC-1295 is described separately. Each batch is GMP-manufactured, HPLC-tested and shipped with a Certificate of Analysis on file.

Before you ask
It is a lyophilized pentapeptide supplied at 5 mg per sealed vial for laboratory research. Ipamorelin is a selective agonist at the ghrelin receptor, GHS-R1a, which places it in the growth hormone secretagogue family rather than among the GHRH analogues. It is bought as a reference standard for release assays, not as a finished medicine.
The lyophilized cake is dissolved in bacteriostatic water, added slowly against the wall of the vial so the peptide is not damaged by foaming or shearing. The vial is then swirled rather than shaken until the solution is clear. Working solutions are kept cold and used within the period noted in the study protocol, because peptides in solution degrade faster than the dry powder.
The peptide is short and cleared quickly, with a reported plasma half-life of about two hours in clinical pharmacokinetic data, far shorter than an esterified GHRH analogue such as CJC-1295 with DAC. That short window is exactly why it appears in pulsatility and acute release designs, where a spike profile is wanted, rather than in work that needs a flat, sustained level across many hours.
Published work reports that the compound was selected for selectivity, so it shows little of the cortisol, prolactin or appetite response that earlier secretagogues produce at comparable release levels. Reported observations are still limited to a small number of studies. Anyone handling the powder should treat it as a research chemical, use gloves and work in a ventilated space.
They act on different receptors. Ipamorelin is a ghrelin receptor agonist, while sermorelin is a GHRH analogue that works through the GHRH receptor on the same pituitary cells. A study can use the two together to compare signalling routes, and the Sermorelin page covers the GHRH side of that comparison in more detail.
