What is Triptorelin?

Triptorelin is a synthetic decapeptide agonist of gonadotropin-releasing hormone (GnRH), with D-Trp substitution at position 6 conferring greater GnRH receptor affinity and proteolytic resistance compared to native GnRH. Continuous or high-frequency exposure produces receptor downregulation and pituitary desensitisation, suppressing LH/FSH secretion and downstream gonadal steroidogenesis. Used as a pharmacological HPG axis suppression tool and GnRH receptor pharmacology reference compound. Research use only.

Research Applications

HPG Axis Suppression

LH/FSH downregulation, pituitary desensitisation, gonadotropin washout kinetics

Pituitary Sensitivity Reset

Post-anabolic/post-HRT HPG axis reactivation studies using single-dose protocols

Prostate & Hormone-Sensitive Cancer Models

Androgen deprivation, castration-resistant transition, tumour growth modelling

Frequently Asked Questions

How do I reconstitute Triptorelin?
Add 1 mL bacteriostatic water to the lyophilized vial, directing liquid down the inner wall. Swirl gently — the 2mg peptide dissolves within 30 seconds. Working concentrations are typically 100–500 mcg/mL.
How should Triptorelin be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 4 weeks. Triptorelin is stable due to its D-Trp6 modification which confers peptidase resistance.
What is the difference between triptorelin and native GnRH?
Native GnRH (Gln-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH₂) has a plasma half-life of 2–4 minutes. Triptorelin replaces Gly6 with D-Trp6, increasing GnRH receptor affinity ~100× and plasma half-life to ~3 hours, enabling sustained receptor engagement and consistent HPG axis suppression in research protocols.
