Dex Pharma GHK-Cu Skin Rejuvenate 100mg/3mL Pen
The Dex Pharma GHK-Cu Skin Rejuvenate 100mg/3ml GHK-Cu pen is a high-concentration copper peptide known for its profound effects on skin regeneration, collagen synthesis, and tissue repair. Because this pen is highly concentrated, it is designed for consistent, daily subcutaneous use to maintain optimal copper levels for cellular healing.
Key Benefits
- Anti-Aging & Skin Radiance: Dramatically increases collagen and elastin production to reduce fine lines and improve skin thickness.
- Enhanced Wound Healing: Accelerates the repair of skin, tendons, and even nerve tissue through its role in the body's natural "remodeling" phase.
- Hair Follicle Support: Research suggests it can enlarge hair follicle size and stimulate growth by improving scalp vascularization.
- Anti-Inflammatory: Acts as a powerful antioxidant, reducing DNA damage and calming systemic inflammation.
Dosing & Protocol
For a 100mg/3ml pen, the concentration is approx 3.33mg per 0.1ml (10 units).
- Standard Research Dose: 1.5mg to 3mg injected once daily.
- Titration: Start at 1-2mg daily to assess tolerance. Side effects like injection site redness or a metallic taste are common and usually fade.
- No Cycling Needed: Unlike many peptides, GHK-Cu can be used indefinitely without breaks, though many users run it for 8-12 weeks for specific skin or hair goals.
GHK-Cu (Copper Peptide) 100mg/3ml FAQ
1. What is GHK-Cu and how does it work? GHK-Cu is a naturally occurring copper complex that acts as a regenerative signal for your cells. It works by "resetting" genes to a more youthful state, specifically those responsible for collagen production and tissue repair.
2. Why use a pen instead of topical creams? While topical GHK-Cu is great for surface skin, subcutaneous injection allows the peptide to work systemically, reaching the deep dermis, hair follicles, and internal tissues for much more profound results.
3. What is the recommended daily dose? Standard research suggests a range of 1.5mg to 3mg per day. Using a 100mg/3ml pen, this is usually a very small volume (approx. 5–10 units) injected once daily.
4. Does it sting or cause redness? Yes, GHK-Cu is known as a "stingy" peptide. It is common to experience localized redness, warmth, or a small welt at the injection site that typically subsides within 30–60 minutes.
5. Do I need to cycle GHK-Cu? No. GHK-Cu does not require a mandatory "off" period or tapering. It can be used consistently, though many users choose 8–12 week cycles to align with their skin or hair goals.
6. Can it help with hair loss? Yes. Research indicates that GHK-Cu can stimulate hair follicles, increase follicle size, and improve the "grip" of the hair, making it a popular choice for thinning hair.
7. Why do I need to take Zinc with it? Consistent copper supplementation can deplete your body's zinc levels. Taking 20–30mg of Zinc daily is highly recommended to maintain a healthy mineral balance.
8. How long until I see skin improvements? Skin texture and glow often improve within 4 weeks, but deep structural changes like reduced fine lines and increased thickness typically take 8–12 weeks of daily use.
9. Can it be used for injury recovery? While not as potent as BPC-157 for acute tears, GHK-Cu is excellent for systemic tissue remodeling and can be a great secondary support for long-term joint and tendon health.
10. What is the "metallic taste" side effect? Some users report a brief metallic taste in their mouth shortly after injection. This is a harmless, transient side effect of the copper entering the system.
11. Is it okay to use while on other peptides? Yes, it stacks exceptionally well with BPC-157 or TB-500 for enhanced healing, or with GH secretagogues for a total anti-aging protocol.
12. When is the best time to inject? Timing is flexible. Most users choose the morning to keep a consistent 24-hour schedule, but it does not affect sleep or energy levels.
13. Does it need to be refrigerated? Yes. To maintain the stability of the copper-peptide bond and prevent degradation, the pen must be stored in the refrigerator.
14. Can I use it for post-surgery healing? GHK-Cu is widely researched for its ability to accelerate wound healing and reduce scar tissue formation. Always consult a provider post-surgery before starting new protocols.
15. How long does a 100mg pen last? At a standard dose of 2mg per day, a 100mg pen provides a 50-day supply. It should be used within 60 days of the first injection for maximum potency.
Research
GHK-Cu, also known as copper tripeptide-1, is a naturally occurring copper-binding peptide made from the amino acids glycine, histidine, and lysine. It has been studied mainly for skin repair, collagen support, wound-healing pathways, tissue remodelling, antioxidant activity, and anti-inflammatory effects. Most published human research has focused on topical GHK-Cu, while injectable use remains less formally studied.
GHK-Cu is currently being researched and is not registered as an approved treatment, but early studies and review literature have shown promising potential in skin and tissue-repair research.
1. Skin repair and anti-aging research — collagen, elasticity, and skin density
A review published on PubMed Central summarised several studies on GHK-Cu and skin ageing. It reported that GHK-Cu has been associated with improved skin appearance, elasticity, firmness, and collagen-related markers. The review also notes that a GHK-Cu facial cream was studied over 12 weeks in women with photoaged skin, where improvements were reported in skin laxity, clarity, fine lines, wrinkle depth, skin density, and thickness.

2. Diabetic wound-healing study — topical GHK-Cu and ulcer repair
A multicentre, randomised, evaluator-blinded, placebo-controlled clinical study looked at glycyl-L-histidyl-L-lysine copper, also known as GHK-Cu, in people with diabetic neuropathic ulcers. The study was published in Wound Repair and Regeneration and evaluated topical GHK-Cu gel as part of wound-care research. This is one of the more commonly cited human wound-healing studies involving GHK-Cu.

3. Tissue remodelling and extracellular matrix research
GHK-Cu has been studied for its effects on the extracellular matrix, which is the structural support network around cells. Research has linked GHK-Cu with stimulation of collagen, elastin, glycosaminoglycans, dermatan sulphate, and chondroitin sulphate, all of which are involved in skin structure, firmness, hydration, and tissue repair. This is one of the main reasons GHK-Cu is frequently discussed in regenerative skin and wound-healing research.

4. Oxidative stress and protective research
A review published in Oxidative Medicine and Cellular Longevity discussed GHK-Cu in relation to oxidative stress, tissue protection, wound healing, and anti-aging skin-care research. The paper describes GHK-Cu as a naturally occurring human peptide with a long history of use in skin-care and wound-healing research, and highlights its potential antioxidant and tissue-protective actions.

5. Anti-inflammatory and regenerative potential
A 2020 review titled “The potential of GHK as an anti-aging peptide” summarised research suggesting that GHK-Cu may support skin remodelling, wound healing, regeneration, and antioxidant/anti-inflammatory pathways. The authors describe GHK-Cu as a peptide of interest for further anti-aging and tissue-repair research, while also making clear that more high-quality studies are needed.

6. Wound biology and glycosaminoglycan research
A study published in the Journal of Investigative Dermatology examined how the tripeptide-copper complex GHK-Cu may modulate glycosaminoglycans and small proteoglycans in wound environments. These molecules are important because they help regulate tissue structure, hydration, and repair signalling during wound healing.

Quick Research Summary
Current research suggests that GHK-Cu may have promising potential in skin repair, collagen support, extracellular matrix remodelling, wound-healing pathways, and anti-inflammatory research. The strongest human evidence is mainly from topical skin and wound-healing studies, while injectable use is far less established in formal clinical research.
