What is Ipamorelin?

Ipamorelin is a five-amino-acid peptide (Aib-His-D-2Nal-D-Phe-Lys-NH2) designed as a ghrelin mimetic. It is frequently cited in the growth-hormone secretagogue literature as one of the more receptor-selective compounds in its class, distinguishing it from older, broader-acting growth hormone-releasing peptides (GHRPs).

How it is understood to work

Ipamorelin binds the growth hormone secretagogue receptor (GHS-R1a) in the pituitary and hypothalamus, triggering calcium-mediated release of growth hormone from somatotroph cells. Research comparing it with earlier secretagogues reports that it produces this GH release with comparatively little accompanying rise in cortisol, prolactin, or ACTH, attributed to its more selective receptor engagement.

Research status

Ipamorelin is studied in growth-hormone pulsatility research, often alongside a GHRH analogue, as well as in models of body composition, bone density, gastrointestinal motility, and post-surgical recovery. The bulk of this evidence comes from cell-based and animal studies; while GHS-R1a pharmacology is well established, ipamorelin itself has not completed human clinical development as an approved medicine.

Concentration check: adding 2 ml of bacteriostatic water to one 10 mg vial gives 5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How does Ipamorelin differ from other GH secretagogue peptides like GHRP-2 or GHRP-6?

All act on the ghrelin receptor, but ipamorelin is reported to be more selective for GH release with less associated cortisol, prolactin, or appetite stimulation in comparative studies.

Why are 5mg and 10mg pack sizes both offered?

Both contain the identical ipamorelin peptide at the same purity specification; the sizes simply differ in total mass per vial for different study-scale needs.

How much Ipamorelin is in this kit?

10 vials of 10 mg each, so 100 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
