Can you bring peptides to Singapore?

Short answer
Depends on specifics

The official rule for Singapore below names peptides. The same rule also covers the other medicines it lists, so read the conditions carefully.

  • Peptides

    depends on specifics

    Only if a doctor prescribed it to you. HSA lets travellers bring up to 3 months' supply of a medicine without prior approval when it was lawfully prescribed to you in your country of residence, you carry a copy of the prescription or a doctor's letter, and it stays in its original container labelled by the dispensing pharmacy. More than 3 months' supply is not allowed. Peptide vials bought online without a prescription don't meet these conditions.

    HSA says retatrutide and cagrilintide are unapproved injectable peptides still in clinical development, and that no regulator, including HSA, has approved them as medicines. It also says labels such as "research use only" or "not for human consumption" should be treated as a warning sign. Approved GLP-1 medicines such as semaglutide and tirzepatide are a different case: see the injectable medication entry, which also covers bringing pens, needles and syringes.

    If you're only changing planes here Not if you stay airside

    You don't need HSA approval for personal medication if you stay in the airport transit zone and don't clear immigration. Prohibited medicines are still not allowed, even in transit.
