A note before we start. This article is editorial science about copper peptides (GHK-Cu). It is not medical advice, and injectable or unregulated peptide products carry real risks — don’t use them without medical supervision. LifeWave X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina. It contains no copper peptides or GHK-Cu, makes no GHK-Cu claim, and is not a skincare product.
You know copper peptides from skincare. What does the science actually say?
If you’ve looked at premium skincare lately, you’ve seen “copper peptides” on the label. The ingredient is GHK-Cu, a small copper-binding peptide that also occurs naturally in the body. Topical GHK-Cu has been studied for skin quality and wound healing, with some encouraging results.
Beyond skincare, GHK-Cu is interesting to ageing researchers because levels appear considerably lower in older adults, and lab studies suggest it interacts with many repair-related processes. But that’s where honest science has to slow down: much of the “whole-body” story comes from lab and computer-based gene-expression studies, not proven benefits in people.
I’m Dave, founder of Simply Younger. Here’s a grounded look at what’s known and what isn’t.
Key takeaways
- GHK-Cu is a naturally occurring copper-binding tripeptide.
- Levels in plasma appear considerably lower in older adults than in young ones.
- Topical copper peptides have the most direct human evidence, for skin.
- Gene-expression findings are mostly from lab and computer-based analyses — not proof of benefit in people.
- There’s no well-validated oral GHK-Cu supplement, and injectable use sits in a regulatory grey area.
- The proven basics — training, sleep, food, sun protection — remain the priority.
What does GHK-Cu do beyond the skin?
Research led by Dr Loren Pickart and later bioinformatics analyses suggest GHK-Cu can shift the activity of many genes in lab settings, in directions associated with tissue repair and lower inflammation. Areas researchers have explored include:
Inflammation. Lab studies suggest GHK-Cu may dampen some pro-inflammatory pathways — relevant to inflammaging, but not yet shown as a human treatment.
Tissue remodelling. It appears to influence enzymes that break down and rebuild collagen, which matters for scar quality and connective tissue.
Stem cell environment. Researchers have explored its role in the stem cell niche; see GHK-Cu and stem cells.
The honest summary: biologically interesting, early-stage in humans.
Why doesn’t a face cream solve everything?
Topical copper peptides act mainly on the skin where they’re applied. The age-related decline researchers talk about is in circulating levels, and whether restoring them would help the rest of the body is unknown. It’s fair to say GHK-Cu belongs in the wider conversation about ageing alongside NAD+ and stem cell exhaustion — but as a research question, not a product promise.

There’s no well-validated oral GHK-Cu supplement, and injectable peptides sit in a regulatory grey area with real risks. Copper from food (shellfish, nuts, seeds, whole grains) provides the mineral, though dietary copper isn’t the same as the peptide — and too much copper is harmful.
What you can do is look after the repair systems in general: resistance training, sleep, a good diet, sun protection and not smoking. My own basics are lifting every second day, 10,000+ steps a day, ten PerfectAmino tablets and 10g of creatine daily, omega-3 and vitamin D, and a monthly Hume Body Pod scan.
Where does X39 fit? Not in this story. X39 contains no copper peptides or GHK-Cu, and no claim is made that it affects GHK-Cu. Separately, I wear an X39 patch daily as a general-wellness habit. LifeWave X39 is a non-transdermal, general-wellness phototherapy patch that gently stimulates the skin with light to support the body’s natural energy flow for strength and stamina. It is not a treatment for any condition.
As an authorised LifeWave Brand Partner I have a financial interest in promoting it.

Frequently asked questions
What are copper peptides?
Usually GHK-Cu — a naturally occurring tripeptide that binds copper and is used in some skincare.
Do copper peptide serums work?
There’s some evidence for skin quality from topical use. Results vary by product and formulation.
How much GHK-Cu do you lose with age?
Studies report substantially lower plasma levels in older adults than in young adults.
Can you take GHK-Cu as a supplement?
Oral products lack solid human evidence, and injectable use is unregulated in many places. Talk to a doctor before using any peptide.
Is GHK-Cu the same as collagen supplements?
No. Collagen supplements provide amino acids; GHK-Cu is a signalling peptide studied for its role in tissue repair.
Does X39 contain or raise GHK-Cu?
No. X39 contains no copper peptides or GHK-Cu, and no claim is made that it affects GHK-Cu. It is a non-transdermal, general-wellness phototherapy patch and is not intended to diagnose, treat, cure or prevent any disease.
