Peptides for anti-ageing

The anti-ageing label is used loosely across cosmetic topicals, growth-hormone-related peptides, and investigational longevity compounds. The regulatory category matters far more than the marketing label.

Regulation note: Most peptides marketed under "anti-ageing" are not approved Australian medicines for that indication. Some adjacent products (e.g. registered growth-hormone medicines) have specific, narrow approved uses that do not include general anti-ageing.
