Overview
GHRP-2 (pralmorelin) is a synthetic hexapeptide growth-hormone secretagogue with the sequence D-Ala-D-2-naphthylalanine-Ala-Trp-D-Phe-Lys-NH2. It acts as an agonist at the ghrelin receptor (GHS-R1a), the same receptor engaged by the endogenous peptide ghrelin, and stimulates growth-hormone release from the pituitary in research models.
In endocrine research it is used as a tool compound to probe GHS-R1a signaling and pituitary growth-hormone secretion, frequently alongside GHRH analogues to dissect the two complementary arms of the growth-hormone axis. It is often compared with related secretagogues such as GHRP-6 and ipamorelin, which differ in sequence and off-target receptor profile. Findings from cell and animal studies are preclinical and should be reported as such.
BioTech Pharma supplies GHRP-2 as a lyophilized powder for laboratory research use only. Lot-specific analytical documentation may be available and should be confirmed for the applicable material. Bulk and custom-fill quantities are available by quote.

Analytical Data
Lot-specific documentation may be available for the applicable material and must be confirmed per enquiry. Where available, it may include:
- HPLC purity result
- LC-MS identity confirmation
- Appearance
- Net content
Request the records you need with your quote and we will confirm availability for your batch.
Procurement Details
Availability, lead time, salt / content basis, and cold-chain requirements depend on the specific lot and quantity, so we confirm them per enquiry rather than publishing fixed figures. Request confirmation for your requirements with your quote and our team will respond with details for the applicable batch.
Storage & Handling
Lyophilized: store desiccated at −20 °C, protected from light. Reconstituted: keep at 2–8 °C and determine working-solution stability empirically per lot, as prepared-solution stability depends on diluent, concentration, and handling.
