Are peptides legal in Taiwan?

Restricted

Peptides are legal in Taiwan only as TFDA-approved prescription medicines dispensed by licensed physicians (e.g. the weight-loss peptides semaglutide, tirzepatide and liraglutide); unapproved research peptides such as BPC-157 and TB-500 are not registered, cannot be lawfully sold for human use, and importing them requires prior TFDA approval or risks seizure.

Legal status overview

Peptides are restricted in Taiwan and are lawful only when they are TFDA-approved, prescription drugs obtained through the regulated healthcare system. The Taiwan Food and Drug Administration (TFDA), under the Ministry of Health and Welfare, regulates all drugs under the Pharmaceutical Affairs Act, which requires TFDA consent before any drug is imported and market approval before any drug is sold. Only three GLP-1 peptide medicines (semaglutide, tirzepatide and liraglutide) are approved for weight control, and the TFDA has been actively cracking down on unofficial online sales, urging the public to use licensed physicians only.

Key points

  • The Taiwan Food and Drug Administration (TFDA), under the Ministry of Health and Welfare, regulates all drugs (including therapeutic peptides) under Taiwan's Pharmaceutical Affairs Act, which governs drug approval, importation and sale. [9]
  • In Taiwan, no drug may be imported or marketed without TFDA approval, as Article 22 of the Pharmaceutical Affairs Act requires the Administration's consent before drugs may be imported, meaning unapproved research peptides have no lawful commercial pathway. [3]
  • Taiwan has approved only three GLP-1 peptide medications for weight control, tirzepatide, semaglutide and liraglutide, which are available only as physician-prescribed drugs. [4]
  • Travelers may bring prescription/controlled drugs into Taiwan for personal use only with a doctor's prescription or certificate, with the quantity limited to a six-month supply for the traveler's own condition. [5]
  • Importing an unapproved drug into Taiwan for personal use generally requires an advance 'Drug Application for Personal Use' approval from the TFDA, so bringing in unregistered research peptides without such consent is unlawful and risks seizure at customs. [2]
  • Taiwan's FDA is actively enforcing against unofficial peptide sales, urging the public to obtain weight-loss injections such as Wegovy® and Mounjaro® only through licensed physicians and cracking down on illegal online supply. [6]
  • The TFDA asked Meta to remove 1,374 posts advertising the illegal sale of medicines and requested that five suspected scam websites be blocked, warning the public not to buy or self-administer weight-loss injections through unofficial channels. [7]
  • Between Jan. 1, 2023 and Dec. 31, 2025, Taiwan's FDA recorded 21 suspected adverse-reaction cases linked to weight-loss injections, reinforcing its position that these peptide drugs should be used only under medical supervision. [8]

Compound-by-compound status

BPC-157BPC-157 is not a TFDA-approved drug in Taiwan and falls into a legal gray area, with no lawful pathway for sale for human use and importation of the unapproved research peptide likely to be seized at customs. [1]
Semaglutide / Tirzepatide (GLP-1 weight-loss peptides)Semaglutide and tirzepatide are legal in Taiwan but are prescription-only, TFDA-approved medicines for weight control that must be obtained through a licensed physician, not bought over the counter or online. [4]
TB-500 (Thymosin Beta-4)TB-500 is not TFDA-approved in Taiwan and sits in a legal gray area as an unapproved research peptide with no lawful route for human sale or use. [1]
Human Growth Hormone (HGH / somatropin)HGH/somatropin is treated as a prescription drug in Taiwan and would fall under the Pharmaceutical Affairs Act's approval-and-prescription framework, though no Taiwan-specific peptide statute naming it was found; this reflects general inference from the drug-approval framework rather than a peptide-specific source.

Frequently asked questions

Can I buy peptides in Taiwan without a prescription?

No. In Taiwan, therapeutic peptides such as semaglutide and tirzepatide are prescription-only TFDA-approved drugs that must be obtained through a licensed physician, and unapproved research peptides like BPC-157 have no legal over-the-counter or online sales channel. [6]

Can I bring peptides into Taiwan for personal use when I travel?

Only approved prescription peptides, and only with documentation: travelers carrying prescription/controlled drugs into Taiwan must present a doctor's prescription or certificate and are limited to a six-month supply, while importing unapproved research peptides generally requires prior TFDA personal-use approval and otherwise risks seizure. [5]

Is it legal to order weight-loss injections like Wegovy® online in Taiwan?

No, buying weight-loss injections through unofficial online channels is illegal in Taiwan; the TFDA has urged the public to obtain them only through licensed physicians and has asked Meta to remove over 1,300 posts advertising illegal medicine sales. [7]

Which weight-loss peptides are actually approved in Taiwan?

Taiwan has approved only three GLP-1 peptide medications for weight control, tirzepatide, semaglutide and liraglutide, all of which are prescription drugs dispensed under medical supervision. [4]

Are unapproved research peptides like BPC-157 or TB-500 legal in Taiwan?

No, BPC-157 and TB-500 are not TFDA-approved, cannot be lawfully sold for human use in Taiwan, and importing these unapproved research peptides is likely to result in seizure at customs and possible legal consequences. [1]
