Are Peptides Legal in Mexico?
Mexico is one of the most popular destinations for peptide tourism. Many pharmacies sell medications including GLP-1 drugs like semaglutide without a prescription, and clinics in cities like Tijuana and Cancun openly offer peptide therapies. Research peptides are widely available with minimal oversight from COFEPRIS, the national regulator. Travelers should be cautious about quality control and be aware that bringing large quantities back across the US border may trigger customs scrutiny.
