GHRP-2 Acetate
GHRP-2 Acetate from the Nexus Growth Hormone Secretagogues catalog, supplied for controlled in-vitro research workflows.
In stock: 5mg is in stock.
For in-vitro research use only. Not for human consumption.
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:

- Pralmorelin (GHRP-2) drug development monograph (Drugs R&D 2004)
Storage, Handling & Stability Guidelines
Store lyophilized GHRP-2 Acetate at -20°C for long-term stability. After reconstitution with sterile diluent, refrigerate at 2–8°C and minimize freeze-thaw cycles by aliquoting working volumes according to your standard operating procedures.
- 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.
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
Orders ship within the United States via USPS; international orders are not accepted. Compounds are supplied as lyophilized research material — follow the storage and reconstitution guidance on the product page and its Certificate of Analysis.
