Ipamorelin
5mg
Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist pentapeptide. Research has shown it stimulates growth hormone release without significantly affecting cortisol or prolactin, making it one of the most selective GH secretagogues available. Often paired with CJC-1295 in synergistic research. One of the most studied compounds in endocrinology. Supplied as lyophilised powder, third-party tested, lab certificate published on this page.
Published research on Ipamorelin is indexed on PubMed. See our full UK buyer's guide for Research Peptides.

Product Specifications
Research Overview
Ipamorelin is a synthetic pentapeptide and highly selective growth hormone secretagogue (GHS). It acts by mimicking the endogenous hormone ghrelin and binding to the growth hormone secretagogue receptor type 1a (GHS-R1a) in the anterior pituitary gland. Ipamorelin is distinguished from other growth hormone releasing peptides (GHRPs) such as GHRP-2 and GHRP-6 by its exceptional selectivity, it stimulates growth hormone release without significantly elevating cortisol, prolactin, or adrenocorticotropic hormone (ACTH) levels. This selectivity makes Ipamorelin the most specific GHS available for endocrine research, minimising confounding hormonal variables in experimental designs. In current research practice, Ipamorelin is frequently studied in combination with CJC-1295 (modified GRF 1-29) for synergistic growth hormone secretion, Ipamorelin acting at the GHS receptor and CJC-1295 acting at the GHRH receptor to produce amplified pulsatile GH release through complementary receptor pathways.
The primary reference is Raun and colleagues (Eur J Endocrinol, 1998), the paper that introduced the molecule and established the property it is known for. They described it as the first growth hormone releasing peptide with a selectivity approaching that of GHRH itself, reporting growth hormone release without the accompanying ACTH and cortisol elevation characteristic of GHRP-6 and hexarelin. Structurally it is a pentapeptide with a C-terminal amide and two D-amino acids, both features contributing to protease resistance.
It was developed as a research compound under the code NNC 26-0161 and taken into a discontinued clinical study, so despite reaching human trials Ipamorelin holds no marketing authorisation in any jurisdiction. It is supplied here as a lyophilised research chemical for in-vitro laboratory use only.

Laboratory Handling
- Store lyophilised vials at -20°C. Reconstituted Ipamorelin should be refrigerated at 2-8°C and used within 4 weeks.
- Reconstitute with bacteriostatic water. Direct the stream of water down the side of the vial and swirl gently.
- Handle under aseptic conditions using sterile syringes. Wipe vial stopper with an alcohol swab before each use.
- Avoid repeated freeze-thaw cycles. Prepare single-use aliquots where possible to maintain peptide integrity.
Frequently Asked Questions
What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide and highly selective growth hormone secretagogue (GHS) that mimics ghrelin and binds to the growth hormone secretagogue receptor type 1a (GHS-R1a) in the anterior pituitary. Unlike GHRP-2 or GHRP-6, Ipamorelin stimulates GH release without significantly elevating cortisol, prolactin, or ACTH. Supplied as lyophilised powder for in-vitro research use only.
Ipamorelin Research Applications
Ipamorelin is studied in endocrine research focused on selective GH secretion, GHS-R1a receptor pharmacology, and pulsatile GH release kinetics. It is frequently combined with CJC-1295 (a GHRH analogue) to study synergistic GH release through complementary GHS and GHRH receptor pathways.
Reconstitution Guide
Allow vials to reach room temperature, then sterilise the rubber stopper of both the peptide vial and the bacteriostatic water vial with an alcohol swab. Slowly draw your bacteriostatic water into a sterile insulin syringe, then inject it gently down the inner glass wall of the peptide vial, never directly onto the lyophilised powder. Once added, gently swirl the vial in a slow circular motion until fully dissolved. Never shake or vortex. The solution should be clear and colourless. Label the vial with the reconstitution date and store immediately.
See our full peptide reconstitution guide and reconstitution calculator for step-by-step protocol.
Storage Instructions
Lyophilised vials should be stored at -20°C, protected from light and moisture, and remain stable for up to 24 months. Once reconstituted with bacteriostatic water, store the solution at 2-8°C (standard refrigerator) and use within approximately 3 months. For storage beyond that, prepare single-use aliquots at -20°C, where reconstituted peptide remains stable for up to 6 months. Avoid repeated freeze-thaw cycles and always handle under sterile laboratory conditions.
