Copper peptides & blends research peptides
GHK-Cu and the multi-component blends built on it. Vial masses ten times larger than a repair peptide, which makes per-milligram pricing the only comparison that means anything here.
3 compounds, 4 vial sizes, from $0.58/mg to $1.29/mg. The cheapest per milligram here is GHK-Cu.

What is in this category
GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, also designated copper tripeptide-1. At around 401.9 g/mol it is very small by peptide standards, it is simple to synthesise, and it ships in 50mg and 100mg vials while a repair peptide ships in 5mg and 10mg.
The blends here - GLOW and KLOW - are built on a large GHK-Cu base with smaller masses of repair peptides added. That is why a GLOW vial is 70mg and a KLOW vial is 80mg while a Wolverine vial is 10mg or 20mg.
The per-milligram trap in this category
GHK-Cu and BPC-157 use very different vial masses and synthesis routes. Their $/mg figures answer different questions. Compare a copper peptide with another copper peptide at a matched mass.
Blends add another wrinkle. A 70mg GLOW vial can produce an attractive $/mg, but that figure is conceptually empty because 50mg of it is a cheap tripeptide and 20mg is not. The comparison that means something is the blend against the single vials covering the same masses, which is on the stack page.
What to check
The copper is part of the molecule, not an additive. Material sold as GHK without the copper is a different item and should be priced and certificated as one. The complex is also visibly distinctive - a deep blue. Color is not an assay, but a vial of GHK-Cu that is not blue warrants a question before anything else.
