Hexarelin 5mg (10 Vials / Kit)

Hexarelin at a glance

Hexarelin is a synthetic hexapeptide from the growth hormone-releasing peptide (GHRP) family, closely related in structure to GHRP-6. Its sequence is His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2; the methyl group on the D-tryptophan was added to improve stability and potency. It was developed in Europe before the endogenous ligand ghrelin had been discovered, and it remains a reference compound in secretagogue research. Supplies are typically a white lyophilized powder.

Price and availability

This is SSRBIO‘s kit of 10 vials at 5mg each (50 mg in total), dispatched from China. The price is $85.80, or $1.72 per milligram of peptide. Across 5 brands listing Hexarelin here, the middle half of prices falls between $1.57 and $1.75 per mg; this kit is inside that range. Your payment waits in escrow until you confirm the parcel arrived, and only then is it released to the brand.

What it is studied for

Hexarelin is an agonist of the growth hormone secretagogue receptor type 1a, the receptor later identified as the target of ghrelin. Activation in the pituitary and hypothalamus triggers robust growth hormone release, and studies also report rises in prolactin, ACTH and cortisol, a broader endocrine footprint than more selective secretagogues show. Separately, hexarelin binds the scavenger receptor CD36, which is expressed in heart and blood vessels; this interaction has been proposed to explain cardiac effects seen in animal models independent of growth hormone. Prolonged exposure is reported to blunt the GH response, a phenomenon described as desensitization.

Research and regulatory status

Human studies in the 1990s and early 2000s examined hexarelin's endocrine effects in healthy volunteers, older adults and people with growth hormone deficiency, and small studies explored cardiac function. Animal work on ischemia, cardiomyopathy and cardiac fibrosis followed. It never progressed to regulatory approval, and as a growth hormone secretagogue it falls under anti-doping prohibitions. Current research interest centers on its CD36 activity and cardiovascular mechanisms.

Checking the lab data

Mass spectrometry should match the expected mass of the six-residue sequence including the methylated D-tryptophan, which distinguishes hexarelin from GHRP-6 and other close relatives. HPLC purity should be reported with a chromatogram, ideally using a method able to separate stereoisomer impurities, since two residues are D-amino acids. Batch number, test date and laboratory name should be present. Expect a white lyophilized cake.

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.
