Half-life calculator
Cagrilintide half-life calculator
Cagrilintide is a long-acting amylin analog, often paired with a GLP-1. Its elimination half-life is about 6.6 days, so a dose largely clears in roughly 33 days. See how it rises as it absorbs, peaks, and falls below.

Solid = while you're dosing; dashed = projected clearance after the last dose. The curve rises as each dose absorbs, then falls — and climbs over the first several doses until it settles into a steady peak-and-trough.
How long does Cagrilintide stay in your system?
A compound is considered essentially cleared after about five half-lives. With Cagrilintide's half-life of about 6.6 days, that's roughly 33 days after your last dose. The calculator's dashed line shows that clearance tail.
Cagrilintide steady state & accumulation
Dosed weekly, each Cagrilintide dose is given before the previous one fully clears, so levels climb over the first several doses and settle into a steady peak-and-trough pattern in about 5 weeks, building to about 1.93× a single dose. That accumulation is why the early weeks can feel different from later on, and why a gradual titration gives your body time to adjust.
Questions
Cagrilintide half-life, answered
What is Cagrilintide's half-life?
Cagrilintide's elimination half-life is approximately 6.6 days, the time for its level in the body to fall by half. This is an approximate figure for illustration; reported values vary.
How long does Cagrilintide stay in your system?
A compound is essentially cleared after about five half-lives, so Cagrilintide largely clears in roughly 33 days after your last dose.
How long until Cagrilintide reaches steady state?
Dosed weekly, Cagrilintide climbs over the first several doses and reaches a steady peak-and-trough pattern in about 5 weeks, building to about 1.93× a single dose.
Does Cagrilintide accumulate between doses?
Yes. At weekly dosing the model shows roughly 1.93× accumulation at steady state, because each dose is given before the previous one has fully cleared.
