Frequently asked
How long does Thymosin Alpha-1 stay in your system?
With a half-life of ≈ 2 h, roughly 97% of a single Thymosin Alpha-1 dose is cleared after five half-lives — about 0.4 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 2 h half-life mean in practice?
Every 2 h, 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 Thymosin Alpha-1 half-life number come from?
Thymosin α1 SubQ pharmacokinetics (PMID 10027483); elimination half-life ≈ 2 h. We cite a primary source for every half-life we publish and version every change.
