What makes it blue?
The copper ion gives reconstituted GHK-Cu a characteristic blue color. Color alone cannot confirm identity or rule out contamination.
Research areas
- Collagen and elastin signaling in fibroblast models
- Wound-model studies
- Hair follicle interest in cosmetic research
Blends
Our GLOW and KLOW blends combine GHK-Cu with other peptides for labs studying multi-compound skin models.
