Get StartedGHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It plays a central role in tissue remodeling, collagen production, and DNA repair. Levels decline sharply with age, which researchers believe contributes to slower healing and visible skin aging.
GHK-Cu may support collagen and elastin production for firmer skin, accelerated wound healing, reduced appearance of fine lines and wrinkles, hair follicle health, and activation of over 4,000 genes associated with tissue regeneration. All benefits are based on published research and individual results may vary.
GHK-Cu is administered as a simple subcutaneous injection. Typical dosing includes one injection per day on a provider-determined schedule. PeRx ships it fully reconstituted and ready to use. No mixing required. Insulin syringes and a step-by-step guide are included.

Rebuild from the inside out. No cream can do this.
Your body makes a small copper peptide called GHK-Cu. It tells cells to build collagen, repair damaged DNA, and remodel tissue. By your 60s, levels have dropped roughly 60% from their peak.
That decline shows up as thinner skin, slower healing, and wrinkles that no topical can reach. Serums and creams barely penetrate the outer layer. An injection delivers GHK-Cu systemically, reaching every tissue that needs it. Replacing what's been lost gives your body back the repair signals it's been missing.
Why do people explore GHK-Cu therapy?
May stimulate collagen and elastin production for visibly firmer, more resilient skin. GHK-Cu outperformed vitamin C and retinoic acid in a controlled trial.
May reduce the appearance of fine lines and wrinkles by reactivating the structural proteins your skin needs to maintain its architecture.
May accelerate wound healing and post-procedure recovery. GHK-Cu supports tissue remodeling across skin, bone, and connective tissue.
May support hair follicle health and thickness. Studies show GHK-Cu can enlarge hair follicles and extend the growth phase of the hair cycle.
May shift gene expression patterns toward regeneration. Researchers found GHK-Cu modulates over 4,000 human genes, including 47 involved in DNA repair.

GHK-Cu vs. Epitalon
Both target aging, but from different angles. Here's how they compare.
GHK-Cu
Skin rejuvenation
| GHK-Cu | Epitalon | |
|---|---|---|
| Best For | Skin rejuvenation, collagen, wound healing | Cellular longevity, telomere protection |
| How It Works | Activates collagen/elastin production + DNA repair | Activates telomerase to maintain telomere length |
| Scope | Skin, connective tissue, hair, wound repair | Cellular aging, DNA protection, melatonin regulation |
| Ideal If You Want | Visible skin improvements, faster healing | Longevity-focused anti-aging at the DNA level |
| Can Combine? | Yes, pairs well with Epitalon | Yes, pairs well with GHK-Cu |

What to Expect: Your GHK-Cu Timeline
Every body is different, but here's the typical progression.
What you may notice:
Skin may feel slightly more hydrated and wounds or blemishes may begin healing faster. Some people notice a subtle improvement in skin texture within the first week.
What's happening:
GHK-Cu is activating fibroblasts and signaling your body to ramp up collagen and elastin production. DNA repair genes are switching on.
What you may notice:
Skin starts to look firmer and smoother. Fine lines may appear softer. Any post-procedure or injury healing is noticeably faster.
What's happening:
New collagen and elastin are being laid down in the skin matrix. Over 4,000 genes are shifting toward regenerative expression patterns.
What you may notice:
Skin elasticity and firmness continue improving. Hair may feel thicker. People around you start commenting on how well your skin looks.
What's happening:
Structural proteins are maturing and strengthening. The cumulative effect of weeks of gene expression remodeling is producing measurable tissue changes.
What you may notice:
Peak results in skin quality, firmness, and elasticity. Scars and blemishes have faded significantly. Skin looks and feels years younger.
What's happening:
The full regenerative program is established. Your provider may adjust to a maintenance protocol to sustain results long-term.

Real experiences. Individual results may vary.
My skin looks better than it has in a decade
“I spent thousands on serums and facials. Six weeks of GHK-Cu did more than all of them combined. My aesthetician noticed the difference before I even told her what I was doing.”
Jennifer L.
GHK-Cu
Healed from surgery remarkably fast
“Had a knee surgery and started GHK-Cu during recovery. My surgeon said my tissue healing was ahead of schedule. The scar is barely visible three months later.”
Mark S.
GHK-Cu
Fine lines around my eyes actually improved
“I was skeptical that anything could improve my crow's feet. By week four the lines were visibly softer. By week eight I stopped wearing concealer around my eyes.”
Diana R.
GHK-Cu
Professional process, real results
“PeRx made the whole thing feel like a legitimate medical process. Provider reviewed everything carefully, medication arrived the next day, and I could see the results within weeks.”
David K.
GHK-Cu
My hair is noticeably thicker
“Started GHK-Cu for skin but noticed my hair getting thicker around week five. My hairstylist asked what I was doing differently. This was the best surprise benefit.”

GHK-Cu Injection
GHK-Cu (glycyl-L-histidyl-L-lysine copper) is a naturally occurring tripeptide found in human plasma, saliva, and urine. It was first identified in the 1970s and has been studied extensively for its role in tissue remodeling, collagen production, wound healing, and gene expression. Levels decline approximately 60% between age 20 and 60.
The most commonly reported side effect is mild redness or irritation at the injection site, which typically resolves within a day. GHK-Cu is a naturally occurring peptide in human plasma and has a well-documented safety profile across decades of research.
GHK-Cu is not recommended for people with Wilson's disease or other copper metabolism disorders, those who are pregnant or breastfeeding, or anyone with an active cancer diagnosis. Always disclose your full medical history during screening.
Most patients notice initial improvements in skin texture and hydration within 1-2 weeks. Visible firmness and fine line reduction typically appear by weeks 2-4, with peak results by weeks 8-12. Results vary based on age, skin condition, and individual biology.
PeRx ships GHK-Cu fully reconstituted and ready to use. Store refrigerated at 36-46 degrees F (2-8 degrees C). Do not freeze. Keep the vial upright and away from direct light.
GHK-Cu is not FDA-approved for any specific condition. It is available as a compounded medication prescribed by licensed providers and prepared at FDA-registered 503A pharmacies.
No. The entire process is done online. Complete a health screening, a licensed provider reviews your profile remotely, and your medication ships directly to your door via FedEx Overnight.
Every order includes a provider evaluation and prescription, pharmacy-grade GHK-Cu from an FDA-registered 503A pharmacy, insulin syringes, alcohol swabs, a step-by-step injection guide, and FedEx Overnight shipping.
Yes. GHK-Cu pairs well with Epitalon (cellular longevity + telomere protection), BPC-157 (tissue repair), and NAD+ (cellular energy). We also offer a GHK-Cu/Epitalon combo vial for comprehensive anti-aging support. Your provider can advise on combinations.
Topical copper peptide serums only penetrate the outer layers of skin. Injectable GHK-Cu delivers a full therapeutic dose systemically, reaching skin, gut, bone, and connective tissue throughout the body. The difference in concentration and reach is significant.
