Frequently asked
How long does Tesamorelin stay in your system?
With a half-life of ≈ 26–38 min, roughly 97% of a single Tesamorelin dose is cleared after five half-lives — about 0.1 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 26–38 min half-life mean in practice?
Every 26–38 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 Tesamorelin half-life number come from?
FDA label: Egrifta (tesamorelin) prescribing information (SC t½ ≈ 38 min). We cite a primary source for every half-life we publish and version every change.
