Effective price per mg uses an active dated override first, then the row-level historical discount, then the vendor default from the same Git revision. Aggregate chart points include exact-comparability offers only. Missing observations remain gaps; the series does not interpolate across unavailable offers or absent snapshots.

What GHK-Cu is

GHK-Cu is a copper-binding tripeptide often discussed in skin-care, hair-care, and wound-signaling contexts. It is one of the better-known examples of how the peptide category extends beyond injectables and metabolic drugs into cosmetic and topical discussions.

Why it matters

On a peptide site, GHK-Cu helps broaden the picture. Not every peptide profile is about body composition or medicalized GLP-1 use. Some peptides are tracked because they show up in dermal, regenerative, or cosmetic product discussions.

Regulatory context

GHK-Cu is not an FDA-approved peptide drug indication in the sense that semaglutide or tesamorelin are. Readers should distinguish between cosmetic ingredient use, research discussion, and regulated therapeutic claims.

Practical reading note

When GHK-Cu is marketed aggressively, the main issue is usually not whether the peptide exists, but whether the seller is overstating what cosmetic or regenerative signaling research can prove.
