Skin Glow Pen – GHK-Cu 100mg
The Skin Glow Pen contains 100 mg of GHK-Cu (Glycyl-L-Histidyl-L-Lysine Copper) in a convenient 2.6 mL pre-filled peptide pen. GHK-Cu is a naturally occurring copper-peptide complex that has been extensively researched for its potential role in skin health, collagen and elastin synthesis, tissue remodelling and cellular repair.
Designed for precision peptide delivery, the Skin Glow Pen provides 240 clicks and is supplied with 6 sterile needles.

About GHK-Cu
GHK-Cu is a naturally occurring tripeptide-copper complex consisting of glycine, histidine and lysine bound to copper. Research has investigated GHK-Cu for its interaction with pathways involved in extracellular matrix regulation, collagen and elastin production, oxidative stress, inflammatory signalling and skin regeneration.
Its potential applications have made GHK-Cu a popular subject of research relating to skin quality, elasticity, tissue repair and healthy ageing.
Research Dosage Protocol
The following protocol is provided as a manufacturer-supplied research reference only and is not a recommendation or instruction for human use:
- Standard research protocol: 5 mg (12 clicks) once daily
- Higher research protocol: up to 10 mg (24 clicks) once daily, where tolerated
- Frequency: once daily
- Timing: morning, with the supplied protocol specifying administration on an empty stomach
- Cycle: 20 consecutive days followed by 2 weeks off
Click conversion: 1 click ≈ 0.417 mg (417 mcg) GHK-Cu.
Precision Peptide Pen Technology
The Skin Glow Pen uses MSSPT (Molecular Stabilisation and Storage Protection Technology), designed to help maintain formulation stability through controlled environmental factors including pH, light, oxygen and moisture.
The pre-filled format provides consistent click-based dosing and eliminates the need for conventional reconstitution.
Storage & Handling
- Store refrigerated where specified by the manufacturer, or in a cool, dry environment within the recommended temperature range.
- Do not freeze.
- Keep the pen capped and protected from direct light and excessive heat.
- Keep out of reach of children.
- Do not use if the solution is cloudy, discoloured, contains visible particles or appears otherwise abnormal.
- Dispose of expired product appropriately.
