Mechanism of Action

Triptorelin is a synthetic decapeptide analog of gonadotropin-releasing hormone (GnRH/LHRH). It acts as a potent GnRH agonist that initially stimulates, then downregulates, the pituitary-gonadal axis through receptor desensitization. This leads to a dramatic reduction in luteinizing hormone (LH), follicle-stimulating hormone (FSH), and subsequently sex steroids. In research contexts, it is studied for its ability to reset the hypothalamic-pituitary-gonadal (HPG) axis.

Primary Benefits

  • HPG axis reset and recovery
  • Restoration of natural testosterone production
  • Reduction of excess estrogen levels
  • Normalization of LH and FSH pulsatility
  • Research applications in reproductive biology

Common Uses

  • Post-cycle therapy (PCT) protocols
  • HPG axis restart after prolonged suppression
  • Hormonal balance restoration
  • Reproductive function research

Side Effects

  • Temporary hormonal flare (first 1-2 weeks)
  • Hot flashes
  • Mood changes
  • Injection site reactions
  • Temporary decrease in libido during flare phase

Contraindications

  • Hormone-sensitive cancers
  • Pregnancy and breastfeeding
  • Known hypersensitivity to GnRH analogs
  • Osteoporosis (long-term use)
