Ipamorelin
Ipamorelin from the Nexus Growth Hormone Secretagogues catalog, supplied for controlled in-vitro research workflows.
In stock: 2mg is in stock.
For in-vitro research use only. Not for human consumption.
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.

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.
Researchers reviewing the literature around this compound can use the peer-reviewed resources below for additional context on mechanism of action, signaling pathways, and controlled laboratory research applications:

- Venkova et al. (2009) — J Pharmacol Exp Ther
- Andersen et al. (2001) — Growth Horm IGF Res
Storage, Handling & Stability Guidelines
Lyophilized Ipamorelin is highly stable due to its small molecular size (pentapeptide). Store at -20°C. Reconstituted solutions should be kept at 2–8°C and used within 21 days.
- 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.
Lab Verification
Nexus maintains batch-level verification records for research compounds in the Lab Verified archive, including HPLC purity review and Mass Spectrometry identity confirmation where current lot data is available.
Shipping

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.
Independently verified Nexus Laboratory batches ship with a Certificate of Analysis documenting HPLC purity (target ≥98%), mass spectrometry identity (expected versus observed mass), and endotoxin context where applicable — verified by independent third-party laboratories and publicly archived; lots awaiting final documentation are labeled certificate pending instead of showing assay values.
