What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial investigates whether the X39 patch, worn daily on the neck or belly, can change blood levels of GHK and GHK-Cu — peptides involved in tissue repair and aging. Healthy adults aged 35 and older will use either the X39 patch or a placebo patch for about a week. Researchers will measure peptide levels before and after use to see if the patch has any effect.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a wearable patch applied to acupuncture points on the neck or belly
What this could lead to
If the patch measurably raises GHK or GHK-Cu levels, it could point toward a non-invasive way to influence these peptides, which are linked to tissue repair and aging.
What could go wrong
This is a small, early-stage study in healthy people, so results may not show a clear effect or translate to any health benefit. The patch's mechanism is unproven.
