Frequently asked questions
- Is peptide therapy legal in Canada?
- Authorized peptide drugs are legal with a prescription. Clinics selling unauthorized research peptides for injection are not selling authorized drugs.
- Is peptide therapy legal in Canada?
- Authorized peptide medicines (for example Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda) are legal with a prescription. Unauthorized 'research' peptides cannot legally be sold for human use.
- What does 'peptide therapy' usually mean online?
- Marketing often means unapproved injectables such as BPC-157, TB-500, CJC-1295 or sermorelin. Those products do not have Health Canada authorization or a DIN.
- Can clinics in Toronto or Vancouver offer peptide therapy?
- Licensed clinicians can prescribe authorized drugs. Offering unauthorized peptides for human use falls outside Health Canada's authorized supply. We don't list or rank clinics.
- Does this page say where to buy or how to dose?
- No. We do not publish sourcing, vendors, prices or dosing. We remove those from submissions.
