GHRP-2 (Pralmorelin) is a synthetic hexapeptide that stimulates GH secretion by activating the ghrelin receptor (GHSR-1a) on pituitary somatotrophs. It is one of the most potent GH secretagogues in its class, though less selective than Ipamorelin — it can moderately affect cortisol, prolactin, and appetite signaling in research models.

Compound Overview
GHRP-2 (Pralmorelin) is a synthetic hexapeptide used in GH secretagogue research. In controlled research models, it stimulates GH secretion by activating the ghrelin receptor (GHSR-1a) on pituitary somatotrophs. It is one of the most potent GH secretagogues in its class, though it is less selective than Ipamorelin and can moderately affect cortisol, prolactin, and appetite signaling in research models.
Research Background & Published Literature
GHRP-2 is among the earliest and most studied GH secretagogues. Published pharmacological characterization appears in journals including Endocrinology and Journal of Clinical Endocrinology & Metabolism, and the compound is frequently used as a reference standard in GH secretagogue research.
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:

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 handling time brief 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.
