Mechanism of action
Gonadorelin is a GnRH analog that stimulates pituitary GnRH receptors, supporting LH and FSH release when administered in appropriate pulse-style contexts.
Half-life & pharmacokinetics
Half-life: Very short acting.
GnRH analogs are short acting and physiologically pulse-dependent. Continuous exposure can differ markedly from pulsatile signaling.
Research dosing reference
100-250 mcg daily or pulse-style research exposure depending on endocrine objective.
Dose interpretation (U-100 units)
| Target dose | U-100 units |
|---|---|
| 100 mcg | 10 units |
| 250 mcg | 25 units |
Units are concentration-specific - confirm against your actual reconstitution volume.
Reconstitution & concentration
| Vial | Preferred reconstitution | Final concentration |
|---|---|---|
| 2 mg | 2 mL BAC Water | 0.010 mg/unit |
Injection timing
Pulse timing is biologically important; avoid interpreting continuous exposure as equivalent to physiologic pulsatility.
Beginner escalation
Start conservatively and use lab-guided interpretation where possible.
Side-effect mitigation
Monitor headache, flushing, mood/libido changes, and endocrine-axis shifts.
Stack compatibility
Avoid combining with other HPG-axis agents without hormone-marker context.
Storage & stability
Lyophilized: refrigerated or controlled cool storage. Reconstituted: refrigerated, protected from heat/light, and handled aseptically.
Protocol duration & reassessment
Use objective-driven, marker-aware courses. Reassess endocrine, mood, libido, blood-pressure, or target-symptom response before repeating or escalating.
Frequently asked questions
What is Gonadorelin and how does it work?
Gonadorelin is a GnRH analog that stimulates pituitary GnRH receptors, supporting LH and FSH release when administered in appropriate pulse-style contexts.
What is the half-life of Gonadorelin?
Gonadorelin: Very short acting. GnRH analogs are short acting and physiologically pulse-dependent. Continuous exposure can differ markedly from pulsatile signaling.
How is Gonadorelin reconstituted for research?
Preferred reconstitution for the 2 mg vial is 2 mL BAC Water, giving 0.010 mg/unit. Always confirm concentration math before any use. Research use only.
Is Gonadorelin FDA approved?
No. Gonadorelin is an investigational research-use-only compound - not for human or animal consumption and not FDA approved.
