A 2022 stability analysis published in the Journal of Pharmaceutical Sciences found that lyophilised copper peptides like GHK-Cu form visible aggregates in 1832% of reconstitution attempts when bacteriostatic water exceeds 8C at the time of mixing

Improves Skin Firmness and Reduces Wrinkles Research shows that GHK-Cu enhances dermal remodeling by: Increasing skin density Boosting elasticity Minimizing fine lines and wrinkles These effects are largely due to increased collagen production and reduced breakdown of structural proteins

While very high oral doses (1,000 to 2,000 mcg) can achieve some passive absorption without intrinsic factor roughly 1% of the dose is absorbed passively many clinicians prefer the reliability and rapid correction offered by injections in this population

It depends on the peptide and the goal
