Two-Part Study of the Effects of the X39 Patch on Circulating GHK and GHK-Cu Levels in Healthy Adults

Starting soon · Not applicable · Has a placebo group

Conditions studied: GHK and GHK-Cu Blood Levels

In brief

The goal of this clinical trial is to investigate GHK and GHK-Cu blood levels pre- and post-intervention in healthy adults, and to investigate the efficacy of X39 patch on GHK and GHK-Cu blood levels in healthy adults compared to a placebo. The main questions it aims to answer are: * What is the change in GHK and GHK-Cu levels from baseline to Day 8? * What is the difference in the change in GHK and GHK-Cu levels from baseline to Day 8 between the X39 patch and placebo? Researchers will compare X39 patches to placebo patches to evaluate their effects on circulating blood levels of GHK and GHK-Cu in healthy adults. Participants will be asked to complete a questionnaire and use the X39 patch or placebo patch.
