What is Gonadorelin?
Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It is studied for its role in stimulating the pituitary to release luteinizing hormone and follicle-stimulating hormone in a pulsatile pattern.
How Gonadorelin works (research mechanism)
Gonadorelin research focuses on pulsatile GnRH-receptor activation - the natural rhythm matters, so frequent administration is modeled to mimic endogenous pulses.
Primary research applications
Reproductive-hormone research
Studied for LH/FSH stimulation endpoints.
Pulsatile-signaling research
Examined for the importance of pulse frequency in models.
Hormone-axis maintenance research
Studied in models of endogenous hormone production.
Research dosing reference
Research references commonly cite 100-200 mcg two to three times daily in pulsatile designs. Reference values only.
Reconstitution & handling
Gonadorelin ships as a lyophilized (freeze-dried) powder and must be reconstituted before use in any liquid research model. Allow the vial to reach room temperature, swab the stopper, then add bacteriostatic water slowly down the inside wall of the vial - never spray it directly onto the powder. Swirl gently until dissolved; do not shake, as shaking foams the solution and stresses the peptide. The volume of water you add sets the concentration: a 5 mg vial reconstituted with 2 mL yields 2,500 mcg/mL, so 0.1 mL measures 250 mcg. A correctly reconstituted Gonadorelin solution is clear; discard if it is cloudy or shows particulate.
Storage & stability
Store un-reconstituted Gonadorelin vials refrigerated and protected from light for long-term stability; the lyophilized form is robust and tolerates shipping. After reconstitution, refrigerate at 2-8C, keep away from light, and use within the typical research window of roughly two to four weeks. The benzyl alcohol in bacteriostatic water helps inhibit microbial growth across that period. Always label reconstituted vials with the concentration and date.
Common research pairings
Generally studied as a standalone GnRH peptide.
How Gonadorelin compares
Gonadorelin is GnRH itself; Kisspeptin acts upstream of it, and HCG mimics LH downstream - three distinct points in the hormone axis.
Safety & research considerations
Supplied for research use only; an advanced compound requiring frequent administration in models. Not for human consumption.
Sourcing, purity & Certificate of Analysis
Every lot of Gonadorelin sold by Peptides Factory Direct is third-party tested to a 99%+ purity target, with identity confirmed by mass spectrometry and purity quantified by HPLC. A Certificate of Analysis (COA) documenting these results is available on request and ties each vial to a tracked lot. Material ships nationwide to all 50 US states with cold-chain handling where appropriate and fast domestic dispatch. This documentation is what separates research-grade Gonadorelin from unverified material - quality is established before the vial ever reaches your lab.
How to order Gonadorelin for research
Gonadorelin can be ordered through the Peptides Factory Direct research portal as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months). Checkout requires confirming you are 21 or older, purchasing for laboratory research only, and that the product is not for human or animal consumption. Bulk and standing-order pricing is available - note it in your order. Open the order portal to view current research sizes and pricing.
