Are peptides legal? Status by country

Every compound in the database, with its legal category in the United States, the United Kingdom, Australia and Canada. Each one links to a page per country that answers "is it legal?" straight away. It uses the same checked facts as the compound profile.

The four government agencies that decide

United States

FDA

U.S. Food and Drug Administration

Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.

United Kingdom

MHRA

Medicines and Healthcare products Regulatory Agency

Licenses medicines for sale in the UK. A compound without a licence to be sold (a marketing authorisation) is an unlicensed medicine. The law only lets it reach people through a prescriber, under the specials scheme (unlicensed medicines made for one patient's needs). It cannot be sold as a research product.

Australia

TGA

Therapeutic Goods Administration

Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.

Canada

Health Canada

Health Canada, Health Products and Food Branch

Allows a drug to be sold by issuing a Notice of Compliance and a Drug Identification Number (DIN). A compound that is not allowed for sale cannot legally be sold for use in people. Bringing in prescription drugs for your own use is also limited.

One rule holds in all four countries. A vial labeled "for research use only" is not an approved product, and that label does not make it legal to use on people. Where a compound is an approved medicine, you get it with a prescription. Where it is not, no product containing it is allowed for people.

General information, not legal advice. Each compound page shows the date we last checked it. Legal status changes, so confirm it with the agency. Educational use only. This database summarizes published research and is not medical advice. Where a dose appears it is a record of what a trial or clinic ran, or what people describe doing, with its source attached. Nothing here is a recommendation for personal use. Sellers named on the price pages are ranked by certificate tier, then price, and any affiliate income is disclosed there. Naming a seller is not a recommendation to buy or use anything.
