Two copper peptides at 100mg
GHK-Cu is glycyl-L-histidyl-L-lysine bound to copper, listed as a 100mg lyophilized vial. AHK-Cu is alanine-histidine-lysine bound to copper, also a 100mg lyophilized vial. Both sit in Skin & appearance. They're separate SKUs. We don't treat AHK-Cu as a size of GHK-Cu, or GHK-Cu as a larger AHK-Cu.
Single-compound notes: What is GHK-Cu? and What is AHK-Cu?. This page puts the two listings next to each other. Appearance-focused research framing.
What each page emphasizes
The GHK-Cu page frames copper-peptide research angles people usually open that listing for: collagen, skin firmness, hair appearance, and scar repair. The AHK-Cu page frames a different copper peptide around collagen, hair appearance, and skin repair, including scalp and follicle appearance. Those lines explain why two copper-peptide cards sit in the same group. They're research framing, not clinic instructions.
The names on the vials are the first catalog difference shoppers notice: GHK vs AHK. Same listed size (100mg). Different sequence. Buying one is not buying the other.
Choosing a page
Open GHK-Cu when you want the glycyl-histidyl-lysine copper listing. Open AHK-Cu when you want the alanine-histidine-lysine copper listing.
