- A reference overview of the four main GHK-Cu formats, their research applications, and key delivery considerations.
- Skin and dermal research: collagen, ECM, wound-healing models
- Absorption through the stratum corneum; depth depends on vehicle, concentration, and formulation
- Serum, cream, solution
- Systemic research, CNS-adjacent models via the olfactory pathway
- May bypass the blood-brain barrier via olfactory/trigeminal nerves; CNS delivery not confirmed for GHK-Cu specifically
- Pre-formulated nasal spray
- Systemic bioavailability research, exploratory
- Subject to enzymatic breakdown in the GI tract; oral bioavailability of intact GHK-Cu not established
- Sublingual or oral tablet
- Systemic and localized delivery research, pharmacokinetics
- Direct delivery to the bloodstream; known, controlled bioavailability
- Lyophilized vial for reconstitution
