Gonadorelin 2mg (10 Vials / Kit)

Gonadorelin at a glance

Gonadorelin is the synthetic form of gonadotropin-releasing hormone (GnRH), identical in sequence to the natural hypothalamic decapeptide: pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2. It carries none of the amino-acid substitutions found in long-acting GnRH analogues such as leuprolide, so it is broken down quickly. Research material is usually supplied as an acetate or hydrochloride salt in freeze-dried form. Because it matches the native hormone exactly, it serves as a standard reference compound in reproductive endocrinology.

Price and availability

This is SSRBIO‘s kit of 10 vials at 2mg each (20 mg in total), dispatched from China. At $31.50 for the kit, that works out to $1.57 per mg. 3 brands currently sell Gonadorelin here, so compare their listings before ordering. 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

GnRH binds its receptor on gonadotroph cells of the anterior pituitary, triggering release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn regulate the gonads. The pattern of stimulation is critical. Pulsatile exposure, which mimics natural hypothalamic secretion, maintains gonadotropin output, while continuous exposure causes receptor desensitization and suppression of the axis. That contrast underpins much of the research on GnRH and explains why long-acting analogues suppress, rather than stimulate, reproductive hormones.

Research and regulatory status

Gonadorelin has a long clinical record. It has been used as a diagnostic agent for testing pituitary gonadotropin reserve and, in pulsatile form, in specialist fertility medicine, though availability of human products varies by country and some have been discontinued. It is also widely used in veterinary reproductive management, particularly in cattle. Research-grade gonadorelin sold here is not a licensed medicine.

Checking the lab data

A credible report should confirm the decapeptide by mass spectrometry, matching the expected mass with the N-terminal pyroglutamate and C-terminal amide in place. HPLC purity with its chromatogram is essential, and the report should state which salt form is present, since acetate and hydrochloride salts change the peptide content per milligram of powder. Measured content per vial, a white freeze-dried cake and a matching batch number round it out.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

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