Are peptides legal in Costa Rica?
Sourced guide to the legal status of peptides in Costa Rica, refreshed automatically from live research.
Overall Status: Restricted
Short answer: Peptides are restricted in Costa Rica: unregistered research peptides such as BPC-157, TB-500, and GHK-Cu have no sanitary registration and the Ministry of Health has declared their sale illegal, while GLP-1-class drugs like Ozempic and Saxenda are legal only as prescription-only, sanitary-registered pharmaceuticals.

Overview
Peptides in Costa Rica are restricted rather than outright banned as a class: the Ministerio de Salud (Ministry of Health) requires every medicine to hold a 'registro sanitario' before it can be legally sold, and research/biohacking peptides like BPC-157 and TB-500 do not have one, making their commercial sale illegal. Approved peptide drugs such as semaglutide (Ozempic), liraglutide (Saxenda) and tirzepatida (Mounjaro) are legal but strictly prescription-only once registered. Compounded ('preparación magistral') peptide products can only be made by an authorized pharmacy for a specific patient with an individual prescription, not for stock or mass sale. Unregistered products, whether GLP-1 analogues or research chemicals, sit in a regulatory gray/illegal zone that the Ministry has been actively flagging with sanitary alerts in 2025-2026.
Key Points
- Costa Rica's Ministerio de Salud stated directly that BPC-157 and TB-500 'no cuentan con registro sanitario en Costa Rica y su venta es, por lo tanto, ilegal' (do not have sanitary registration and their sale is therefore illegal). [1]
- The Ley General de Salud (General Health Law) of Costa Rica prohibits the commercialization of medicines and therapeutic products without a sanitary registration issued by the Ministry of Health. [1]
- The Ministerio de Salud has publicly named retatrutide, tesamorelin, BPC-157, TB-500 and GHK-Cu as peptides being marketed in Costa Rica for muscle gain, weight loss, and anti-aging without the required sanitary permits. [2]
- If the Ministerio de Salud detects an unregistered peptide product on the market in Costa Rica, it can order immediate seizure, temporary or permanent closure of the selling business, and mandatory removal of inventory from shelves and warehouses. [1]
- Compounded peptide preparations in Costa Rica may only be legally made by an authorized pharmacy for one specific patient under an individual medical prescription, and cannot be manufactured to hold as stock or marketed to the public en masse. [4]
- Travelers may personally bring medicines, including peptide drugs, into Costa Rica in their original packaging with an accompanying prescription in quantities consistent with personal treatment, while importing an unregistered peptide for personal medical use beyond that requires prior authorization from the Ministerio de Salud. [7]
- Costa Rica's Ley General de Salud No. 5395, Article 117, allows the Ministerio de Salud to authorize importation of unregistered medicines primarily for the Caja Costarricense de Seguro Social (CCSS) and other state health entities, generally on a case-by-case or emergency basis rather than for general public retail. [11]
- The Ministerio de Salud confirmed that Ozempic (semaglutide), Saxenda (liraglutide) and Mounjaro KwikPen (tirzepatida) were evaluated for quality, safety and efficacy and are authorized in Costa Rica strictly as prescription medicines. [4]
Peptide-by-peptide status in Costa Rica
| BPC-157 | BPC-157 is illegal to sell in Costa Rica because the Ministerio de Salud has confirmed it holds no sanitary registration and lacks the human clinical trials required for approval. [1] |
|---|
| TB-500 | TB-500 is unregistered and its commercial sale is illegal in Costa Rica according to the Ministerio de Salud, which lists it among peptides promoted for muscle recovery without required authorization. [2] |
|---|
| Semaglutide / Tirzepatide (GLP-1 class) | Semaglutide is legal in Costa Rica only as the prescription-only, sanitary-registered product Ozempic for diabetes, while unregistered semaglutide, liraglutide, and tirzepatide products sold outside authorized pharmacies are flagged by the Ministry as lacking sanitary registration or still being in clinical investigation phase. [4] |
|---|
| Tirzepatide (Mounjaro/Zepbound) | Tirzepatide is not registered with Costa Rica's Ministerio de Salud and is therefore absent from the legal market, meaning it cannot be commercially sold and would require personal-import authorization from the Ministry to obtain lawfully. [7] |
|---|
| Human Growth Hormone (HGH) / growth-hormone secretagogues (CJC-1295, ipamorelin, MK-677) | Research-use HGH-related secretagogues such as CJC-1295, ipamorelin, and MK-677 have no sanitary registration or approval as medicines in Costa Rica and fall outside the legal pharmaceutical framework, unlike registered somatropin products which would require a medical prescription under the same registro sanitario regime that governs all peptide drugs.

Frequently asked questions
No — buying BPC-157 or TB-500 in Costa Rica is not a lawful retail transaction regardless of prescription, because the Ministerio de Salud has stated these peptides lack sanitary registration and their sale is illegal.
[1]
Yes, within limits: travelers can bring registered peptide medicines into Costa Rica in original packaging with a valid prescription in quantities matching personal treatment need, but bringing in larger amounts of an unregistered peptide requires prior authorization from the Ministerio de Salud.
[7]
Only registered products can be lawfully prescribed in Costa Rica, and currently only semaglutide is registered there as Ozempic for diabetes, so a telehealth prescription for weight-loss semaglutide, liraglutide, or tirzepatide use is limited to what the Ministerio de Salud has actually authorized and reminds must be used only under medical evaluation and follow-up.
[4]
A store in Costa Rica caught selling unregistered peptides can face immediate seizure of the product, temporary or definitive closure of the business, and a sanitary order requiring removal of all inventory from shelves and warehouses.
[1]
It is only legal if the compounded peptide preparation is made by a pharmacy authorized by Costa Rica's Ministerio de Salud for one named patient under an individual prescription; mass-produced or stockpiled compounded peptides marketed to walk-in clinic clients are not permitted.
