Overview
Gonadorelin acetate is the synthetic decapeptide form of GnRH (gonadotropin-releasing hormone), used to probe pituitary LH/FSH release in fertility research. Pulsatile versus continuous administration produces opposite endocrine effects in clinical study designs. Synthetic GnRH decapeptide for pulsatile fertility and diagnostic stimulation research.
Structure & identity
Decapeptide GnRH — pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2
- Sequence / structure
- Decapeptide GnRH — pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2
Mechanism
Synthetic GnRH stimulates pituitary LH and FSH in a pulsatile-dependent manner. LH/FSH release is pulse-frequency dependent — continuous vs pulsatile infusion literature differs.

Literature highlights
- Synthetic GnRH stimulates pituitary LH and FSH in pulsatile-infusion fertility research.
- Diagnostic stimulation tests measure gonadotropin response curves.
- Very short half-life requires precise infusion timing in reproductive endocrinology models.

Stability & storage phases
| Phase | Condition | Guidance |
|---|---|---|
| Lyophilized | Sealed vial, refrigerated (2–8 °C) | Intact lyophilized cake or powder is typically stable for months to years per published stability data; protect from moisture, light, and repeated freeze-thaw of the dry vial. |
| Reconstituted | Bacteriostatic water (0.9% benzyl alcohol), refrigerated | Most aqueous peptide solutions remain usable for approximately 2–4 weeks refrigerated; verify published stability data and label with reconstitution date. |
| Working aliquots | Pre-drawn syringes or microtubes, frozen (−20 °C) | Aliquot promptly after mixing to limit freeze-thaw cycles on the main vial; thaw once and use to reduce protease-mediated degradation. |
Stability windows are formulation-dependent — verify published data and your lab SOP.
Reconstitution reference table
| Vial (mg) | Diluent (mL) | mcg/mL | Units @ 100 mcg | Units @ 250 mcg | Units @ 500 mcg |
|---|---|---|---|---|---|
| 2 | 2 | 1000.0 | 10 | 25 | 50 |
| 5 | 2 | 2500.0 | 4 | 10 | 20 |
U-100 insulin syringe scale (100 units = 1 mL). Illustrative only — not dosing guidance.
Reconstitution steps
- Allow vial to reach room temperature (15–30 min)
- Swab rubber stopper with alcohol prep pad
- Draw calculated bacteriostatic water into syringe
- Inject diluent slowly down vial wall — do not spray directly onto cake
- Gently swirl until fully dissolved — do not shake vigorously
- Label with date, concentration, and diluent volume
- Refrigerate and use within your lab stability window
Typically reconstituted with 1–2 mL bacteriostatic water.
