Timing
GHK-Cu can be injected morning or evening. Some users prefer AM to align with the body’s natural repair cycle. Inject subcutaneously in the abdomen, outer thigh, or upper arm fat pad.
Cycling
Run 8 – 12 week cycles followed by a 4 – 8 week break. Cycling helps maintain receptor sensitivity and prevents potential copper accumulation over extended periods.
Stacking
Commonly paired with BPC-157 or TB-500 for enhanced tissue repair. GHK-Cu also complements skin-focused protocols alongside topical retinoids or growth factors.
Storage
Keep unreconstituted vials refrigerated at 2 – 8 °C. After mixing with bacteriostatic water, refrigerate and use within 3 – 4 weeks. Do not freeze the reconstituted solution.
