Gonadorelin (GnRH) (10mg) Research Peptide: A Native Decapeptide for Hypothalamic-Pituitary-Gonadal Axis Studies

If your research investigates reproductive endocrinology, the hypothalamic-pituitary-gonadal (HPG) axis, or the molecular mechanisms of fertility regulation, Gonadorelin (GnRH) (10mg) research peptide offers a precisely defined and extensively validated synthetic tool. Gonadorelin is a synthetic decapeptide that is chemically and physiologically identical to the endogenous mammalian gonadotropin‑releasing hormone (GnRH).

As the pivotal central regulator of the HPG axis, it stimulates the synthesis and secretion of luteinising hormone (LH) and follicle‑stimulating hormone (FSH) from the anterior pituitary. Unlike modified GnRH superagonists (e.g., leuprolide, buserelin) that cause receptor downregulation, Gonadorelin retains the native, unmodified decapeptide sequence, making it an essential tool for studying physiological GnRH‑mediated signalling, pulsatile hormone release, and the complex feedback mechanisms governing reproductive health. This makes Gonadorelin (GnRH) (10mg) research peptide a valuable tool for laboratories investigating endocrinology, reproductive biology, and neuroendocrine signalling.

At Chinese Grey Peptides, we supply high‑purity Gonadorelin (GnRH) (10mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to >95% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into the HPG axis, gonadotropin regulation, and reproductive endocrinology begin with uncompromising quality.

What Is Gonadorelin and How Does It Work?

To fully appreciate the research potential of Gonadorelin (GnRH) (10mg) research peptide, it is essential to understand its biochemical structure and the precise mechanism by which it regulates the reproductive axis.

The Native Decapeptide

Gonadorelin is a synthetic decapeptide with the sequence pGlu‑His‑Trp‑Ser‑Tyr‑Gly‑Leu‑Arg‑Pro‑Gly‑NH₂. Its molecular formula is C₅₅H₇₅N₁₇O₁₃, and its molecular weight is approximately 1182.3 g/mol. It has a CAS number of 33515‑09‑2. The peptide is produced naturally by neurons in the septal preoptic area of the hypothalamus and is released into the pituitary portal blood, where it travels to the anterior pituitary gland. The synthetic form is chemically identical to the endogenous hormone, making it a precise tool for studying physiological GnRH‑mediated signalling.

Mechanism of Action: GnRH Receptor Activation and Gonadotropin Release

The biological activity of Gonadorelin (GnRH) (10mg) research peptide is mediated through its interaction with the GnRH receptor, a G‑protein‑coupled receptor (GPCR) located on pituitary gonadotrophs:

• Receptor Binding: Gonadorelin binds specifically to GnRH receptors on the surface of pituitary gonadotroph cells.

• Signal Transduction: This binding activates a signalling cascade involving the phospholipase C pathway, which culminates in the secretion of LH and FSH.

• Gonadotropin Release: The released LH and FSH travel through the bloodstream to the gonads, where they regulate steroidogenesis, gametogenesis, and reproductive function.

• Pulsatile Secretion: Physiological GnRH release is pulsatile, and the frequency and amplitude of these pulses determine the differential release of LH and FSH. Gonadorelin has a plasma half‑life measured in minutes (~4 minutes), making it suitable for studying pulsatile dynamics.

Research Note: Pulsatile vs. Continuous Administration

The mode of administration is critical in GnRH research. Pulsatile administration of Gonadorelin stimulates pituitary LH and FSH secretion, which in men with an intact hypothalamic‑pituitary axis increases testicular Leydig cell stimulation and can raise circulating testosterone. In contrast, continuous administration produces receptor desensitisation and suppression of LH and testosterone. This dual response makes Gonadorelin a versatile tool for studying both the stimulatory and inhibitory aspects of GnRH signalling.

Reconstitution & Handling Protocol for Gonadorelin (GnRH) (10mg)

Proper reconstitution of Gonadorelin (GnRH) (10mg) research peptide is critical for maintaining its structural integrity and biological activity.

Step 1 – Preparation

• Bring the sealed Gonadorelin vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature.

• Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.

Step 2 – Vial Sanitisation

• Wipe the rubber stopper of the Gonadorelin vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.

Step 3 – Reconstitution

• Draw your desired volume of diluent into a sterile syringe. A typical reconstitution uses 1‑2 mL of bacteriostatic water per vial. A 10 mg vial reconstituted with 10 mL bacteriostatic water yields a concentration of 1 mg/mL = 1,000 mcg/mL.

• Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.

• Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously.

Step 4 – Aliquoting & Storage

• Immediately after dissolution, aliquot the reconstituted Gonadorelin into single‑use sterile vials.

• Store aliquots at 2‑8°C. Do not freeze reconstituted solution.

• Once thawed (if stored frozen as aliquots), use within a short period. Reconstituted solution is stable refrigerated for up to 14 days.

Concentration Reference Table for Gonadorelin (GnRH) (10mg)

*Adjust diluent volume based on your experimental requirements. For diagnostic applications, a single IV bolus of 100 mcg (or 2.5 mcg/kg, max 100 mcg) is commonly used. For fertility preservation during TRT, doses of 100‑200 mcg injected 2‑3 times per week are typical.
