Topical vs Systemic

What it's actually good for

Recovery

Research Supported

Strong evidence for skin and tissue repair, particularly in wound healing and post-procedure contexts.

Longevity

Weak Evidence

Promising gene modulation data exists, but long-term human longevity outcomes are currently unproven.

How it works

GHK-Cu is a naturally occurring tripeptide-copper complex extensively studied for its role in skin regeneration, wound healing, and gene modulation. While topical efficacy for anti-aging is well-documented in human trials, systemic benefits for internal repair and longevity are largely supported by animal models and mechanistic data.

It acts as a copper carrier and modulates the expression of over 4,000 human genes, promoting collagen synthesis and antioxidant enzyme activity while suppressing inflammatory cytokines.

Safety

  • Injection site pain and burning are extremely common side effects.
  • May cause copper/zinc imbalance if used systemically without zinc supplementation.
  • Topical overuse can lead to skin irritation or the 'copper flush' effect.
