Are peptides legal in Singapore?
Sourced guide to the legal status of peptides in Singapore, refreshed automatically from live research.
Overall Status: Restricted
Short answer: Peptides such as BPC-157, TB-500, and GLP-1 weight-loss peptides are restricted in Singapore: they are treated as prescription-only medicines or unregistered therapeutic products by the Health Sciences Authority (HSA), so they cannot be legally bought, sold, advertised, or imported without a doctor's prescription and, in many cases, prior HSA approval.

Overview
Peptides are restricted in Singapore rather than freely legal or outright criminalized for the individual user: Singapore's Health Sciences Authority (HSA) regulates therapeutic peptides as prescription-only medicines or unregistered health products under the Health Products Act 2007 and the Poisons Act 1938, meaning lawful use generally requires a doctor's prescription and, for many products, formal HSA registration. Popular research peptides like BPC-157 and TB-500 are not registered with HSA for human use and are sold illegally when marketed online for weight loss or muscle gain, while GLP-1 drugs such as semaglutide (Wegovy) are HSA-approved but strictly prescription-only, with advertising to the public banned. Personal importation of any peptide-containing medicine without a valid prescription and, where required, HSA approval, is not permitted and can lead to enforcement action.
Key Points
- Singapore's Health Sciences Authority (HSA) has publicly warned that injectable peptides sold online for weight loss and muscle gain without medical supervision are illegal because they are classified as prescription-only medicines. [1]
- In Singapore, pharmaceutical and biologic drugs that were previously regulated under the Medicines Act 1975 and the Poisons Act 1938 are now regulated as "therapeutic products" under the Health Products Act 2007, which the Health Sciences Authority administers. [2]
- Singapore's Ministry of Health and HSA jointly stated that advertisements for prescription-only medicines, including weight-loss injectables such as GLP-1 receptor agonists, are not allowed in any form of media, including social media and telehealth platforms. [3]
- The HSA approved semaglutide (marketed as Wegovy) for weight management use in Singapore in 2023, making it a legally prescribable but prescription-only medicine rather than an over-the-counter product. [4]
- Travelers bringing personal medications into Singapore may import up to three months' supply of non-prohibited prescription medicine without prior HSA approval, provided they carry a valid prescription or doctor's letter, but they remain responsible for verifying that the medicine does not contain a prohibited or controlled substance. [5]
- Selling or supplying unregistered health products, including illegal injectable peptides, in Singapore can result in prosecution, with penalties for sellers and suppliers including imprisonment of up to 2 years and/or fines of up to S$10,000 under enforcement actions cited by HSA. [6]
- Bringing peptide-based research chemicals like BPC-157 or TB-500 into Singapore for personal use without a prescription and any required HSA approval is not lawful, since these compounds are not HSA-registered for human use and HSA actively monitors online sales and imports. [7]
- The Health Sciences Authority and the Central Narcotics Bureau jointly regulate the import, export, and transhipment of controlled drugs and substances into Singapore, requiring an HSA license for such activities. [8]
Peptide-by-peptide status in Singapore
| BPC-157 | BPC-157 is not approved or registered for human use in Singapore and is treated as an unauthorized/banned research peptide, so selling, advertising, or importing it for personal use without HSA clearance is illegal. [9] |
|---|
| TB-500 (Thymosin Beta-4) | TB-500 is not HSA-registered for human use in Singapore and, like BPC-157, is subject to enforcement action when sold online for recovery or performance purposes without a prescription. [1] |
|---|
| Semaglutide / GLP-1 class (Wegovy, Ozempic) | Semaglutide-class GLP-1 medicines are legally available in Singapore only as prescription-only medicines, with Wegovy specifically HSA-approved for weight management since 2023 and public advertising of such drugs prohibited. [4] |
|---|
| Human Growth Hormone (HGH/somatropin) | Injectable HGH is treated in Singapore as a prescription-only therapeutic product outside the general health-supplement category, so obtaining it without a doctor's prescription for an approved medical condition is not permitted, though no HSA-specific primary source on HGH enforcement was found in this research. |

Frequently asked questions
No, you cannot legally buy injectable peptides in Singapore without a prescription, because the HSA classifies them as prescription-only medicines and has warned that online sellers offering them for weight loss or muscle gain without medical supervision are acting illegally.
[1]
You may bring up to three months' supply of a non-prohibited prescription medicine into Singapore without prior HSA approval if you carry a valid prescription or doctor's letter, but unregistered research peptides like BPC-157 or TB-500 are not treated as approved personal medications and importing them can trigger confiscation or enforcement action.
[5]
Yes, a licensed Singapore doctor can prescribe HSA-approved GLP-1 medicines such as Wegovy for eligible patients, but MOH and HSA have stated that these prescription-only medicines cannot be advertised to the public on any platform, including telehealth websites and social media.
[3]
Sellers and suppliers of unregistered health products in Singapore, including illegal injectable peptides, are liable to prosecution and, if convicted, can face imprisonment of up to 2 years and/or a fine of up to S$10,000, based on HSA enforcement actions against sellers of adulterated or unregistered products.
[6]
No, BPC-157 is not registered with Singapore's HSA for human use, and it is grouped among the injectable peptides that HSA has warned against, meaning it cannot be lawfully sold or supplied for personal or bodybuilding use in Singapore.
