Those findings support topical skin-care relevance, but they do not establish GHK-Cu as a treatment for systemic aging
PeRx delivers it as a subcutaneous injection, oral glutathione is largely broken down before it reaches your cells, so injection gives far higher bioavailability
Nobody is suggesting you should overpay for peptides
Collectively, these recent contributions argue that future GSH-centric redox sensing and nanomedical approaches should (i) incorporate organelle targeting (especially mitochondria) to exploit subcellular redox heterogeneity, (ii) embed analyte-responsive activation into both therapeutic and imaging components, (iii) combine biochemical sensing with optical or thermal engineering for spatiotemporal control, and (iv) favor clinically translatable carriers (e.g., PLGA) for delivery
Plus, all the ingredients are organic, so its perfect for anyone whos mindful of what they put into their body
