How to Use the Peptide Calculator
Peptide calculators are essential tools for researchers and healthcare practitioners to determine precise dosing, especially for injectable formulations.
Basic Calculation Formula:
- Determine peptide concentration: Total peptide amount (mcg) ÷ Volume of solution (mL)
- Calculate required volume for desired dose: Desired dose (mcg) ÷ Concentration (mcg/mL)
Example Calculation:
- If you have 5mg of GHK-Cu (5000mcg) and add 3mL of bacteriostatic water:
- Concentration = 5000mcg ÷ 3mL = 1666.7mcg/mL
- For a 250mcg dose, required volume = 250mcg ÷ 1666.7mcg/mL = 0.15mL (15 units on a standard insulin syringe)
GHK-Cu Dosages and Chart
GHK-Cu can be administered through several routes, each with specific dosage recommendations based on available research and clinical observations.
Here is a simple chart summarizing common GHK-Cu dosage recommendations by method:

| Topical (Hair) | 4% (Scalp) | Apply after washing |
| Injectable (SC) | 1-2 mg | Daily, often cycled (e.g., 4-6 weeks on, 2-4 weeks off) |
| Oral (Liposomal) | 100-200 mcg | Daily (Requires specific liposomal formulation) |
Topical Applications
Topical formulations of GHK-Cu are among the most common and accessible methods of administration, particularly for skin and hair applications.
Concentration Guidelines:
- Standard range: 2% to 10% for skin applications
- Face, neck, and scalp applications: 4% concentration
- Eye area applications: 2% concentration (due to skin sensitivity)
- Typical dosage: One dollop of cream (approximately 50mg of GHK-Cu)
Application Protocols:
- Serums: Apply to clean, dry skin 1-2 times daily without rinsing
- Face creams: Apply morning and night as part of daily skincare routine
- Shampoo/scalp products: Apply after washing hair, massaging deeply into the scalp
For optimal results, consistent application over a period of three months may be necessary to observe noticeable improvements in skin health and rejuvenation.
Injectable Formulations
Injectable GHK-Cu provides a more direct delivery method but requires proper administration techniques and carries additional considerations.
Standard Dosage Recommendations:
- Typical concentration: Available as a 10 mg/mL solution in 5 mL vials
- Daily dosage: 1-2 mg (0.03-0.06ml or 3-6 units) subcutaneously
- Alternative recommendation: 0.2 mL delivered subcutaneously once daily
- Injection concentration range: 0.1% to 1.0%
Administration Schedule:
- Frequency: Daily injections, preferably at the same time each day
- Recommended schedule: Monday through Friday (with weekends off)
- Important note: Injectable GHK-Cu should be administered under professional supervision due to risks associated with self-injection
Oral/Ingestible Options
Oral administration of GHK-Cu requires special formulation to prevent breakdown in the digestive system.
