GHK-Cu, a naturally occurring copper peptide, has gained attention for its potential benefits in skin health, wound healing, and anti-aging. Understanding the correct dosage is essential to maximize its effects safely. This post explores GHK-Cu dosage, how it works, and practical guidance for its use.
GHK-Cu stands for glycyl-L-histidyl-L-lysine copper complex. It is a small peptide that binds copper ions and plays a role in tissue repair and regeneration. Research shows it can stimulate collagen production, reduce inflammation, and promote skin healing.

How GHK-Cu Works in the Body
GHK-Cu naturally occurs in human plasma, but its levels decline with age. It acts as a signaling molecule that activates genes involved in tissue repair and anti-inflammatory responses. When applied topically or injected, it can:
Stimulate collagen and elastin synthesis
Promote wound healing
Reduce fine lines and wrinkles
Improve skin firmness and elasticity
These effects make GHK-Cu popular in skincare products and clinical treatments.
Typical Dosage Forms of GHK-Cu
GHK-Cu is available in several forms, including:
Topical serums and creams: Concentrations usually range from 0.01% to 0.05%
Injectable solutions: Used in clinical settings, doses vary based on treatment goals
Supplements: Oral forms exist but have limited bioavailability
The dosage depends on the delivery method and intended use.
Recommended Dosage for Skin Care
For topical use, most products contain GHK-Cu at concentrations between 0.01% and 0.05%. This range balances effectiveness and safety. Applying a serum with 0.02% GHK-Cu once or twice daily can support skin rejuvenation.
When using topical GHK-Cu:
Cleanse skin before application
Apply a small amount to target areas
Follow with moisturizer and sunscreen during the day
Consistency over weeks or months is key to seeing results.
Injectable GHK-Cu Dosage Guidelines
In medical or cosmetic procedures, GHK-Cu injections may be used to accelerate wound healing or improve skin texture. Dosages vary but typically range from 2 to 5 mg per injection session.
Injection protocols often include:
Multiple sessions spaced 1 to 2 weeks apart
Injection into the dermis or subcutaneous tissue
Combination with other treatments like microneedling
These procedures should be performed by trained professionals to ensure safety.
Safety and Side Effects
GHK-Cu is generally well tolerated. Side effects are rare but may include:
Mild skin irritation or redness with topical use
Temporary swelling or bruising at injection sites
Avoid using GHK-Cu on broken or infected skin. People with copper allergies should consult a healthcare provider before use.
Practical Tips for Using GHK-Cu
Start with lower concentrations to assess skin tolerance
Use products from reputable brands with clear ingredient lists
Store GHK-Cu serums in cool, dark places to maintain stability
Combine GHK-Cu with other skin-supporting ingredients like vitamin C or hyaluronic acid for enhanced effects

Summary of Key Points
GHK-Cu dosage depends on the form and purpose:
Topical serums: 0.01% to 0.05%, applied daily
Injectable forms: 2 to 5 mg per session, administered by professionals
Oral supplements: less common, with uncertain absorption
Using the right dosage supports skin repair and anti-aging benefits while minimizing risks. Always follow product instructions and consult experts when considering injections.
