Ipamorelin is a selective growth hormone secretagogue that stimulates the pituitary gland through ghrelin receptor (GHSR-1a) activation. Unlike other GHS compounds such as GHRP-6 or Hexarelin, Ipamorelin demonstrates high selectivity for GH release without significantly affecting cortisol, prolactin, or ACTH levels in research models.

The dossier.
Compound Overview
Ipamorelin is a selective growth hormone secretagogue used in research models to evaluate ghrelin receptor (GHSR-1a) activation and downstream pituitary GH release signaling. In published experimental contexts, Ipamorelin is distinguished from GHS compounds such as GHRP-6 or Hexarelin by its high selectivity for GH release without significant effects on cortisol, prolactin, or ACTH levels in research models.
Research Background & Published Literature
Ipamorelin has a focused literature base as a selective GH secretagogue. Raun et al., published in the European Journal of Endocrinology, characterized the compound's selectivity profile, and the peptide is frequently evaluated with GHRH analogs such as CJC-1295 in combination research designed to study synergistic GH signaling.

Storage, Handling & Stability Guidelines
Use the applicable lot/source record for storage of unopened material. Any diluent selection, preparation, temperature, aliquoting, or post-reconstitution hold conditions must be established by a qualified laboratory under a validated SOP; this page does not establish a stability window.
- Keep ambient-temperature exposure brief during handling to help preserve compound integrity.
- Reseal vials promptly after each withdrawal to reduce moisture exposure.
- Use appropriate personal protective equipment and follow institutional chemical safety protocols at all times.
- For traceability, label all aliquots with compound name, concentration, reconstitution date, and operator initials.
Quality Assurance & Lab Verification
A finalized public Certificate of Analysis is available for this catalog item. Review the public COA for the applicable lot. Lot-specific identifiers, assay values, and methods are maintained in that record and are not repeated in this product dossier.
Shipping
Orders ship within the United States via USPS; international orders are not accepted. Laboratories should follow their validated SOP together with any handling fields published for the represented product or lot; no universal prepared-solution condition is inferred here.

Research context.
Ipamorelin has been studied extensively as a selective GH secretagogue. Published research by Raun et al. in the European Journal of Endocrinology characterized its selectivity profile. It is frequently used in combination research with GHRH analogs such as CJC-1295 to study synergistic GH signaling.
Verification standard.
Certificate information is lot-specific. A finalized public record shows only the methods, fields, and results present for that named lot. A pending certificate state exposes no assay values and must not be interpreted as analytical verification. Review Nexus lab verification.
