Frequently asked

How long does CJC-1295 stay in your system?

With a half-life of ≈ 8 days, roughly 97% of a single CJC-1295 dose is cleared after five half-lives — about 40 days. Repeated dosing accumulates and takes correspondingly longer to clear.

What does a ≈ 8 days half-life mean in practice?

Every 8 days, 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 CJC-1295 half-life number come from?

CJC-1295 (DAC) half-life studies (see monograph; no-DAC differs sharply). We cite a primary source for every half-life we publish and version every change.
