Half-life calculator
GHRP-2 half-life calculator
GHRP-2 is a potent growth-hormone-releasing peptide. Its elimination half-life is about 1.5 hours — so a dose largely clears in roughly 8 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 GHRP-2 stay in your system?
A compound is considered essentially cleared after about five half-lives. With GHRP-2's half-life of about 1.5 hours, that's roughly 8 hoursafter your last dose. The calculator's dashed line shows that clearance tail.
GHRP-2 steady state & accumulation
GHRP-2'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 GHRP-2 are approximate — reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
GHRP-2 half-life, answered
What is GHRP-2's half-life?
GHRP-2's elimination half-life is approximately 1.5 hours — 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 GHRP-2 stay in your system?
A compound is essentially cleared after about five half-lives, so GHRP-2 largely clears in roughly 8 hours after your last dose.
How long until GHRP-2 reaches steady state?
With a half-life of 1.5 hours dosed daily, GHRP-2 clears almost completely between doses, so it doesn't meaningfully accumulate — each dose behaves like the first.
Does GHRP-2 accumulate between doses?
Not meaningfully — its half-life is short relative to daily dosing, so it clears between doses (accumulation ≈ 1×).
