Are Peptides Legal in Thailand?
Thailand has become a popular destination for peptide tourism, with clinics openly offering peptide therapy including BPC-157, TB-500, and GLP-1 agonists. Clinic-administered peptides are widely available and the Thai FDA takes a relaxed approach to peptide therapies offered through licensed clinics. Approved medications like semaglutide are available by prescription. Purchasing peptides through established clinics is straightforward, though importing them yourself is a greyer area.
