GHK-Cu Dosage Guide: Protocols, Timing & How Much to Take (2026)

Dosage Protocols

No FDA-approved dosing guidelines exist for GHK-Cu. The following protocols are derived from preclinical research and community reports:

For subcutaneous injection, conservative dosage starts at 0.5 mg once daily. Note: to date, human studies use topical administration, not subcutaneous. All injectable dosing is extrapolated from preclinical data and community use.

Cycling is sometimes recommended to prevent receptor desensitization. An example cycle consists of 4-8 weeks of daily administration followed by 2-4 week breaks. Some users extend cycles to 12 weeks for significant wound healing or hair restoration.

  • Starting dose: 0.5 mg once daily subcutaneously
  • Standard dose: 0.5-1 mg once daily
  • Localized concerns: 0.5 mg daily, combined with topical application to target areas
  • Anti-aging skin protocol: Some practitioners recommend 2-3 times weekly rather than daily

Begin with the minimum effective dose and adjust based on observed results and tolerance. Individual responses vary.

Frequently Asked Questions

While not strictly required, cycling is recommended to prevent potential receptor desensitization. Common protocols include 4-8 weeks on followed by 2-4 weeks off.
