Do peptides work for skin, hair or libido?
They are three different questions with three different states of evidence, and grouping them confuses more than it helps.
For skin, GHK-Cu is the compound with the oldest literature in the catalog: it was described in the 1970s and has been studied on collagen synthesis and extracellular matrix remodeling, including work with topical application. It is also the one that appears most in commercial cosmetic formulations, which are a different product from the lyophilized reagent on this page.
For hair, the evidence is considerably thinner and comes mostly from cellular models. For sexual function, PT-141 has a real clinical program —it was studied in phase 3 trials— but that makes it a molecule with data, not a product approved to be sold here.
What is sold on this page is a laboratory reagent labeled RUO: it has no sanitary registration, it is not intended for human or veterinary consumption, and that is why it comes with no dosing schedules or promises of results. If your interest is a treatment and not an experiment, the right conversation is with a doctor, not with a reagent supplier.
