Reported ranges by source
| Reported range | Source type | Evidence strength |
|---|---|---|
| 1–2 mg daily | Practitioner protocols | Practitioner protocol (not a clinical trial) |
| 1–3 mg daily | Dr. Trevor reports | Practitioner report (not a clinical trial) |
| No injectable dose from a human trial | Human trial (published study) | No human-trial evidence found in the PeptideWhiz study library |
Amounts are shown as each source reports them. Where sources disagree, the table lists each one; there is no single agreed amount.
Published human trials
No human-trial evidence found in the PeptideWhiz study library for GHK-Cu. The amounts above come from practitioner protocols and Dr. Trevor reports only, so the evidence level is low. See the GHK-Cu research overview for the studies we index.
FAQ
What GHK-Cu dosage is reported in research?
Reported in research: 1–2 mg daily in practitioner protocols, and 1–3 mg daily in Dr. Trevor reports. No human-trial dose is reported in our study library. Sources vary.
Is there human-trial evidence for GHK-Cu dosing?
No. No human-trial evidence found in the PeptideWhiz study library for GHK-Cu; the amounts listed come from practitioner protocols and Dr. Trevor reports.
Why do the reported GHK-Cu amounts differ?
Each source studied or described a different group, form, goal and time frame, so reported amounts vary between sources. PeptideWhiz lists each one with its source type instead of picking a single amount.
Where can I convert a GHK-Cu amount into syringe units?
The PeptideWhiz calculator for GHK-Cu converts a vial amount, water volume and target amount into mL and syringe units. It does not suggest an amount.
