GHRP-6 5mg

GHRP-6 at a glance

GHRP-6, short for growth hormone releasing peptide-6, is a synthetic hexapeptide with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. It came out of structure-activity work on modified enkephalin-like peptides, well before its target receptor was cloned and before ghrelin was discovered. The formula is C46H56N12O6 and the molecular weight 873.0 g/mol. Unlike most listings in this catalogue, it is offered as a pre-filled research pen containing 10 mg rather than a vial of freeze-dried powder.

Price and availability

Cyprus Peptides lists this single 5mg vial, shipped from Cyprus. The price is $97.00, or $19.40 per milligram of peptide. Across 10 brands listing GHRP-6 here, the middle half of prices falls between $0.60 and $0.92 per mg; this kit is above the typical range. Checkout goes into escrow first; the funds move to Cyprus Peptides once delivery is confirmed.

What it is studied for

As an agonist at GHS-R1a, GHRP-6 acts on pituitary somatotrophs and on hypothalamic neurons. At the pituitary, receptor signaling raises intracellular calcium and releases growth hormone; in the hypothalamus it is proposed to increase GHRH input and counter somatostatin. The same receptor drives hunger signaling, and GHRP-6 is noted in animal studies for a pronounced orexigenic effect. Modest rises in ACTH, cortisol and prolactin have been reported. Separate work describes binding to the scavenger receptor CD36 in cardiac tissue, examined in cytoprotection models, which may be independent of ghrelin-receptor activity.

Research and regulatory status

GHRP-6 has a long preclinical record in pituitary cell, rodent and larger-animal studies, plus early human pharmacology that helped define the secretagogue concept. It was never developed into an approved therapy, and later compounds with greater selectivity replaced it in most secretagogue research. Cytoprotection and appetite studies continue in academic settings. Research-grade GHRP-6 is sold for laboratory use only, and its quality and fill should be judged from the lab report attached to each listing.

Checking the lab data

For a pen, the report should test the solution itself: mass-spectrometry identity consistent with 873.0 g/mol, HPLC purity, and a measured concentration so the stated 10 mg per pen can be checked. Sterility or bioburden and endotoxin results are relevant for any pre-filled liquid. The report should also list the diluent and any preservative, the pen's lot number, and a test date recent enough to reflect stability in solution.

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.
