[25] During times of low cellular stress, a complex forms through direct proteinprotein interactions between GSTP and the C -terminus of JNK, effectively preventing the action of JNK and thus its induction of the JNK pathway
Using copper peptides alongside strong acids, vitamin C, or retinoids may reduce topical GHK-Cu peptide benefits for skin rejuvenation or increase irritation
