Half-life calculator
GHK-Cu half-life calculator
GHK-Cu is the copper peptide, used for skin and recovery. Its elimination half-life is about 2 hours, so a dose largely clears in roughly 10 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 GHK-Cu stay in your system?
A compound is considered essentially cleared after about five half-lives. With GHK-Cu's half-life of about 2 hours, that's roughly 10 hours after your last dose. The calculator's dashed line shows that clearance tail.
GHK-Cu steady state & accumulation
GHK-Cu'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 GHK-Cu are approximate: reported values vary and absorption is especially uncertain. Use this as an illustration, not a precise pharmacokinetic profile.
Questions
GHK-Cu half-life, answered
What is GHK-Cu's half-life?
GHK-Cu's elimination half-life is approximately 2 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 GHK-Cu stay in your system?
A compound is essentially cleared after about five half-lives, so GHK-Cu largely clears in roughly 10 hours after your last dose.
How long until GHK-Cu reaches steady state?
With a half-life of 2 hours dosed daily, GHK-Cu clears almost completely between doses, so it doesn't meaningfully accumulate; each dose behaves like the first.
Does GHK-Cu accumulate between doses?
Not meaningfully. Its half-life is short relative to daily dosing, so it clears between doses (accumulation ≈ 1×).
