GHRP-2 at a glance

GHRP-2, also known as pralmorelin, is a synthetic hexapeptide from the growth hormone secretagogue family, a group of compounds that emerged before the natural hormone ghrelin was discovered. Its sequence, D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, includes several D-amino acids and an unnatural naphthylalanine residue, features that improve stability. It belongs to the same broad group as GHRP-6, hexarelin and ipamorelin, all of which act on the receptor later identified as the ghrelin receptor.

Price and availability

Sold by Jinlu Peptides and sent from China, this listing is a kit of 30 vials at 5mg each (150 mg in total). $113.40 buys the whole kit, which is $0.756/mg. 7 brands sell GHRP-2 on GLP1 Forum Escrow, with a typical price of $0.70–$1.16 per mg (median $0.756); this listing is inside that range. Checkout goes into escrow first; the funds move to Jinlu Peptides once delivery is confirmed.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

What it is studied for

GHRP-2 binds GHS-R1a, the ghrelin receptor, which is expressed on pituitary somatotrophs and in the hypothalamus. Activation is reported to trigger growth hormone release through calcium-dependent signaling and to counter the inhibitory influence of somatostatin, and the peptide also appears to act at the hypothalamic level on GHRH neurons. Compared with more selective secretagogues, GHRP-2 has been reported to raise cortisol, ACTH and prolactin to some degree and to increase appetite, reflecting the broad distribution of ghrelin receptors.

Research and regulatory status

GHRP-2 has been studied in humans in diagnostic and physiological research, and under the name pralmorelin it has been used in Japan as a diagnostic agent for assessing growth hormone secretion. Beyond that, it is not approved as a medicine in the United States or Europe. Research covers pituitary function, body composition and appetite, mainly in small studies. It is prohibited in sport under the World Anti-Doping Agency list.

Checking the lab data

A credible report should show a mass spectrometry result matching the amidated hexapeptide and HPLC purity with the chromatogram. Because the sequence relies on D-amino acids and naphthylalanine, stereochemistry matters; mass alone cannot rule out an incorrect isomer, so chiral analysis or clear synthesis documentation adds weight. Measured content per vial, a white freeze-dried cake, and the testing lab and batch number should be stated.

No independent report is attached to this listing yet. You can compare brands that publish one on the marketplace or browse the lab reports directory.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 5 mg vial dissolved in 2 mL gives 2.5 mg/mL, or 5 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

How does GHRP-2 differ from ipamorelin?

Both act on the ghrelin receptor and both are synthetic, but ipamorelin is a pentapeptide described in animal studies as more selective for growth hormone release. GHRP-2 is a hexapeptide that has been reported to produce stronger accompanying changes in cortisol, prolactin and appetite. Researchers choose between them depending on which effects they want to isolate.

What does the name growth hormone-releasing peptide mean?

The name dates from the period when these synthetic peptides were known to release growth hormone through an unidentified receptor. Later work identified that receptor and its natural ligand, ghrelin. The GHRP label stayed in use, so GHRP-2 and GHRP-6 are best understood as early synthetic ghrelin-receptor agonists.

How much GHRP-2 is in this listing?

30 vials of 5mg each — 150 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does Jinlu Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
