GHK-Cu Nasal Spray 50mg delivers fast absorption and a subtle onset to support skin repair, tissue recovery, and immune function from within. It accelerates the healing properties of GHK-Cu throughout the body—cleaner and more comfortable than injections. Use once daily, 1–2 sprays (625mcg - 1250mcg), with up to 80 uses per bottle. Paraben-free, dye-free, and fragrance-free. Usage: Use 1–2 sprays daily (625mcg–1250mcg) into each nostril on a clean, dry nose. The full absorption effect is fast and direct. READ BEFORE USE: Do not spray all the way up the nose. Simply insert the nozzle just inside the nostril. Spray once gently, keeping the nozzle level and avoiding direct upward aim into the sinuses. Inhale slowly through the nose to allow the mist to absorb. It is not a drug or medication. Use at your own discretion.
