Frequently asked
How long does BPC-157 stay in your system?
With a half-life of ≈ 4–6 h, roughly 97% of a single BPC-157 dose is cleared after five half-lives — about 1 days. Repeated dosing accumulates and takes correspondingly longer to clear.
What does a ≈ 4–6 h half-life mean in practice?
Every 4–6 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 BPC-157 half-life number come from?
PMC9794587 (BPC-157 pharmacokinetic review; PK-PD disconnect noted). We cite a primary source for every half-life we publish and version every change.
