These were L-NAME responsive/L-arginine responsive, L-NAME responsive/L-arginine non-responsive, L-NAME non-responsive/L-arginine responsive, opposite or parallel, NO-specific (L-NAME and L-arginine counteract each others response), or NO-non-specific (L-NAME and L-arginine do not counteract each others response) (Table 3)

However, the physiological effects (such as changes in inflammation or tissue healing signals) may last longer than the measurable presence of the peptide

Clinically tested

Aging is one reason

Because studies have evaluated GHK-Cu across multiple cell types (including fibroblasts and keratinocytes) and in preclinical models, it is commonly used to support mechanistic work on aging-related tissue changes, repair biology, and copper homeostasisstrictly within controlled research designs

It is widely studied in controlled laboratory environments for its potential role in cellular signalling and regenerative research pathways
