GHK-Cu has a reported half-life of about 2 hours. Under a daily dosing schedule, steady state is reached at roughly 4.3 half-lives — about 9 hours — and accumulation is essentially negligible: each daily dose clears almost fully before the next.
The blue line plots concentration as a percentage of the first-dose peak. The dashed reference line marks the steady-state peak. After the last dose, concentration drops below 1 % of the peak after about 14 hours — seven half-lives.
GHK-Cu is a copper-binding tripeptide studied for skin repair, collagen synthesis, and anti-inflammatory effects. Typical daily doses range from 1 to 4 mg. The very short half-life means each dose is independent, with no meaningful carry-over to the following day.
