What is GHRP-2?

GHRP-2 is a synthetic hexapeptide active at the ghrelin and growth hormone secretagogue receptor family. It is used in pituitary cell models to characterise receptor pharmacology through calcium flux and second messenger assays, and NuVion stocks it in Australia as a 10mg lyophilised vial.

  • Synthetic hexapeptide active at the ghrelin and GHS receptor family
  • Used to characterise receptor pharmacology in pituitary cell models
  • Applied in calcium flux and second messenger assays
  • Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry

GHRP-2 structure and research use

GHRP-2, also known as pralmorelin, has the sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2. It is one of the growth hormone releasing peptides, synthetic agonists of the ghrelin receptor GHS-R1a, alongside GHRP-6 and ipamorelin. In the laboratory it serves as a reference compound for secretagogue receptor pharmacology in pituitary cell models.

GHRP-2 research applications

  • Competition binding on GHS-R1a membrane preparations or whole cells, ranking affinity against ghrelin, GHRP-6 and hexarelin
  • IP-One HTRF inositol phosphate accumulation and PKC translocation assays that quantify the Gq arm
  • Primary pituitary cell culture, with GH released into the medium quantified by ELISA
  • LC-MS/MS and RP-HPLC method development, where the naphthylalanine residue gives a distinctive fragmentation pattern

Storing and handling GHRP-2

Before reconstitution
Keep the sealed vial cool, dry and out of direct light. General practice for lyophilised peptides.
After reconstitution
Reconstitute with bacteriostatic or sterile water, store at 2 to 8°C and avoid repeated freeze-thaw cycles. No stability-tested shelf life is published for this product.

GHRP-2 questions

Where can I buy GHRP-2 in Australia?
NuVion stocks GHRP-2 in Australia as a 10mg vial of lyophilised powder, posted from Australian stock on a tracked express service. A sample was analysed by Janoshik Analytical on 23 April 2026, with purity of 99.22% by RP-HPLC. Bacteriostatic water is sold separately. GHRP-2 is supplied as a research material only and is not on the Australian Register of Therapeutic Goods.
What is GHRP-2 used for in research?
It is used as a reference agonist at GHS-R1a. Common work includes competition binding, calcium and inositol phosphate assays in receptor-expressing lines, beta-arrestin recruitment assays, and pituitary cell culture in which GH released into the medium is quantified by ELISA.
How does GHRP-2 work at the cell level?
GHS-R1a is a class A GPCR found on pituitary somatotroph cells and on hypothalamic neurons. GHRP-2 binds within the transmembrane pocket and stabilises the active receptor conformation, with binding affinity in the low nanomolar range in competition assays against radiolabelled ghrelin analogues. The GHRP-2 research profile covers the mechanism in full.
How many D-amino acids are in GHRP-2?
Three of the six residues in GHRP-2 are D-enantiomers: D-alanine at position 1, D-2-naphthylalanine at position 2 and D-phenylalanine at position 5. Mammalian aminopeptidases and endopeptidases act on L-configured backbones, which is why the peptide holds up in serum-containing culture medium.
How does GHRP-2 behave on a C18 HPLC column?
GHRP-2 elutes later than GHRP-6 on a C18 column under the same gradient. Its naphthalene and indole rings make it markedly more hydrophobic, and the same rings give useful absorbance around 280 nm for HPLC quantification.
How is GHRP-2 related to hexarelin?
GHRP-2 and hexarelin belong to the same hexapeptide series and differ most at position 2. GHRP-2 carries D-2-naphthylalanine there, while hexarelin carries D-2-methyl-tryptophan. Positions 3, 4 and 6, which are Ala, L-Trp and Lys-NH2, are conserved across the series.
What is the difference between GHRP-2 and GHRP-6?
Both are synthetic hexapeptide agonists of the ghrelin receptor GHS-R1a, with different sequences. GHRP-2 is D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2 and GHRP-6 is His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. NuVion stocks both separately.
