FAQ

Quick answers about The Peptide Dex and how to use it.

What is The Peptide Dex?

A free, plain-language directory of peptides across skin care, hair, wellness, fitness, gut, and research topics. No account required.

Is this medical advice?

No. Everything here is educational. Talk to a doctor, dermatologist, or pharmacist for personal recommendations—especially for prescription GLP-1 drugs or injectable peptides.

How do I find an ingredient from my label?

Search the INCI name or marketing nickname on your slice homepage, browse A–Z, or check our Also Known As index for aliases like Ozempic or Matrixyl.

Why are there different subdomains?

Each vertical (skin, hair, wellness, etc.) has its own focused guide at a subdomain—so hair peptides do not clutter a skin-care search.

Do you sell peptides?

No. We link to retail skin-care products where available; we do not sell research chemicals or prescription drugs.

How often is data updated?

Peptide entries are curated and refreshed from public databases (PubChem, OpenFDA) and our editorial seeds. Ingredient lists on real products change—always read the bottle.
