Gonadorelin is a synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH) produced by the hypothalamus. The protocol explains that, when administered in brief, pulsatile fashion, it binds GnRH receptors on pituitary gonadotroph cells and triggers secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH then supports testosterone production via Leydig-cell stimulation in males and is also involved in ovulatory signaling in females, while FSH contributes to spermatogenesis and ovarian follicle development. A key mechanistic distinction emphasized is dosing pattern: continuous GnRH agonist exposure can desensitize pituitary receptors and suppress gonadotropin output, whereas intermittent micro-dosing is intended to preserve receptor responsiveness and mimic physiologic GnRH pulses. In short, gonadorelin works by restoring upstream GnRH signaling to drive LH/FSH release and downstream reproductive endocrine function.

Transient flushing
  • Use aseptic technique: wipe vial stopper with alcohol; use new sterile syringe/needle
  • Add diluent slowly down the vial wall to minimize foaming
  • Gently swirl/roll until fully dissolved (do not shake)
  • Label vial with reconstitution date and concentration; protect from light
  • Refrigerate after reconstitution (commonly 2–8 °C) unless protocol states otherwise
  • Avoid repeated freeze–thaw cycles
  • Bacteriostatic Water for Injection contains benzyl alcohol preservative (multi-dose); follow protocol for beyond-use (many peptide protocols use ~28 days after mixing)
  • Avoid benzyl-alcohol-containing diluents in neonates/infants (safety warning for benzyl alcohol)
