Frequently asked
How long does Gonadorelin stay in your system?
With a half-life of ≈ 10–40 min, roughly 97% of a single Gonadorelin dose is cleared after five half-lives — about 0.1 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 10–40 min half-life mean in practice?
Every 10–40 min, the remaining amount halves: 100% → 50% → 25% → 12.5%, and so on. The curve above plots exactly this decay for a single dose.
Where does this Gonadorelin half-life number come from?
GnRH pharmacology (Belchetz 1978, PMID 100883); terminal half-life 10–40 min. We cite a primary source for every half-life we publish and version every change.
