What is elimination half-life?

The time for the plasma concentration to fall by half. After roughly 4–5 half-lives, less than 5% of a single dose remains.

Where do the half-life values come from?

They are approximate research-literature values and vary with route of administration, individual, and compound quality. Use them as reference only.

What is steady-state accumulation?

With repeated doses before full elimination, the level builds to a plateau. The factor estimates that multiple relative to a single dose's peak.

Peptide half-life & decay

Visualise how a single dose decays from the compound's reported half-life and estimate steady-state accumulation with repeated dosing. Reference values, for research use only.

Pick a compound to load its reported half-life, or enter one manually. The curve shows the remaining fraction of a single dose; the accumulation factor estimates buildup at a fixed dosing interval.
