Its especially effective when inflammation is a barrier to recovery

Copper in excess is genuinely toxic, and in a zebrafish model free copper caused heart toxicity (Hsiao et al., 2020) though in that same study the GHK peptide chelated copper and reduced the harm, so GHK-Cu is not equivalent to free copper

The pen packaging clearly protects against temperature fluctuations during transit

Copper Peptides, particularly GHK-Cu (glycyl-L-histidyl-L-lysine bound to copper), are naturally occurring complexes that have been widely studied in preclinical research for their potential role in cellular signaling and tissue-related processes
