Peptide therapy for women

"Peptide therapy for women" is not a single, defined treatment. It is an umbrella phrase, and what it means depends entirely on the goal. For weight, it usually points to a licensed GLP-1 medicine. For skin, it points to cosmetic peptides. For joints and hair, it often means collagen. These sit in completely different UK regulatory categories, so the useful first step is to separate them.

The categories behind the phrase

• · Weight management: GLP-1 medicines (semaglutide, tirzepatide), licensed prescription-only, prescriber decides.
• · Skin: cosmetic peptides (copper peptides, Matrixyl), topical general-sale skincare.
• · Joints, hair, nails: collagen peptides, ingestible food supplements.
• · Recovery / growth-hormone support: research peptides, sold research use only, no human trials for these uses.

Why the distinction matters

A licensed GLP-1 medicine and a research-use-only peptide are not interchangeable, even though both are "peptides". One is a regulated medicine accessed through a prescriber; the other is sold under research-use-only wording that does not authorise human treatment. PeptideClear sets out which category a product sits in so the right route is clear; we do not recommend a specific product for a specific person.
