GHK-Cu side effects and results in studies
Absence of a reported effect in a small study is not evidence of safety. Each statement is tied to the study that reported it. None of the cited abstracts states a tolerability finding for GHK-Cu.
Adverse events reported
The cited abstracts do not list adverse events.
Outcomes measured
No outcome data are tabulated yet.
What the studies don't show
Results hold for the setting studied and no further. Purity data confirms what is in the vial and says nothing about whether a compound works.
