Half-life calculator
Tesamorelin half-life calculator
Tesamorelin is a stabilized GHRH analog (Egrifta). Its elimination half-life is about 36 minutes, so a dose largely clears in roughly 3 hours. 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 Tesamorelin stay in your system?
A compound is considered essentially cleared after about five half-lives. With Tesamorelin's half-life of about 36 minutes, that's roughly 3 hours after your last dose. The calculator's dashed line shows that clearance tail.
Tesamorelin steady state & accumulation
Tesamorelin's half-life is short relative to daily dosing, so it clears almost completely between doses and doesn't meaningfully accumulate (about 1×). Each dose behaves much like the first; the chart shows a clean spike that returns to baseline before the next one.
Half-life figures for Tesamorelin are approximate: reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
Tesamorelin half-life, answered
What is Tesamorelin's half-life?
Tesamorelin's elimination half-life is approximately 36 minutes, 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 Tesamorelin stay in your system?
A compound is essentially cleared after about five half-lives, so Tesamorelin largely clears in roughly 3 hours after your last dose.
How long until Tesamorelin reaches steady state?
With a half-life of 36 minutes dosed daily, Tesamorelin clears almost completely between doses, so it doesn't meaningfully accumulate; each dose behaves like the first.
Does Tesamorelin accumulate between doses?
Not meaningfully. Its half-life is short relative to daily dosing, so it clears between doses (accumulation ≈ 1×).
