ghk-cu hair growth study randomized GHK Peptide Clinical Trial (2016) — Research Summary GHK-Cu Hair Growth Guide: Protocols

This structure gives GHK-Cu a characteristic blue hue in solution, with an absorption peak at 610630 nm

A finished capsule or spray should be evaluated using testing metrics that confirm both the identity of the peptide and the amount of peptide present in the final formulation

Expect the reconstituted solution to carry a blue to blue-violet tint contributed by the Cu(II) centre of the GHK-Cu component

Approach marketing claims accordingly and expect gradual, modest changes over months rather than rapid transformation

Do not mix separate-vial peptides in one syringe they have different stability and pH requirements
