What this family has in common
- Copper peptides: GHK-Cu (copper-linked glycyl-histidyl-lysine tripeptide), studied for the extracellular matrix and skin remodeling, and AHK-Cu, studied for the hair follicle.
- KPV: tripeptide derived from the end of alpha-MSH, studied for inflammation.
- IGF-1 LR3: long-life analogue of IGF-1.
- Melanocortins: MT-1, MT-2 and PT-141 (bremelanotide), melanocortin receptor agonists.
- Cosmetic: SNAP-8 (octapeptide), hyaluronic acid serum + GHK-Cu + SNAP-8 ready to use, Lemon Bottle.
- Blends: Wolverine Stack (BPC-157 + TB-500) and KLOW (GHK-Cu, BPC-157, TB-500, KPV).

Frequently Asked Questions
What is the difference between GHK-Cu in a bottle and GHK-Cu serum?
The 50 mg vial is a lyophilized powder intended for research purposes and must be reconstituted. The 60 ml serum is a ready-to-use cosmetic product combining hyaluronic acid, GHK-Cu, and SNAP-8.
Why is GHK-Cu blue?
The blue color comes from copper bound to the peptide: a blue powder or solution is normal. The "GHK-Cu Blue" guide explains how the copper content is measured and how to store the bottle.
GHK-Cu or AHK-Cu: which one to choose?
Both are copper peptides. GHK-Cu is primarily studied for its effects on the skin and extracellular matrix, while AHK-Cu is studied for its effects on the hair follicle. The PeptiLine comparison details their differences.
