About GHK-Cu
GHK-Cu is a naturally occurring copper tripeptide found in human plasma, and its concentration falls sharply with age — roughly a two-thirds decline between your twenties and your sixties. That decline is what made it interesting to researchers in the first place, and it has since accumulated one of the deepest research literatures of any peptide in cosmetics, covering collagen and elastin synthesis, skin remodelling, hair follicles and wound healing.
It is the compound behind both the GLOW and KLOW stacks and behind our topical serum, and this 100mg vial is the raw material form. At R450 for 100mg it is also the best value per milligram in the skin category by a wide margin, which is why people running longer protocols buy it here rather than as part of a stack.
What it’s researched for
Research context, not medical advice. Everything we sell is supplied for research purposes.
Collagen and elastin
The core of the GHK-Cu literature: signalling skin cells to build rather than adding structural protein directly, which is what separates it from a collagen supplement.
Skin remodelling
Studied for texture, fine lines and scarring — the same wound-healing pathways, applied to skin that is not injured.
Hair follicles
A well-documented research interest and a common reason people choose GHK-Cu over other skin compounds.
Antioxidant activity
Researched for antioxidant and anti-inflammatory properties, which is the argument for it in reactive skin that tolerates retinoids and acids poorly.
Reconstitution and storage
A 100mg vial is the largest peptide load in the skin category, so give it room: 2 to 3 mL of bacteriostatic water, added slowly down the glass. At 3 mL that is roughly 33mg/mL. GHK-Cu solution is a distinct blue — that is the copper, and it means the peptide-copper complex is intact rather than that anything has gone wrong. Unopened vials are stable at room temperature in transit but belong in a fridge once they arrive, and out of a parked car in a Highveld summer.
