Semaglutide
Semaglutide is a 31-residue GLP-1 receptor agonist, molecular weight about 4,114, CAS 910463-68-2, first developed by Novo Nordisk. It is the active ingredient in several approved prescription medicines. Buy research-grade Semaglutide in Costa Rica starting at $220 for a 10mg vial, with 20mg and 30mg options available for ongoing research. Transparent USD pricing, no customs fees, 2–4 day local delivery, and an automatic 15% discount when you order five or more vials of the same size.
Buy Semaglutide in Costa Rica: Lab-Tested & Locally Stocked
Semaglutide is a modified version of GLP-1, a hormone the gut releases after eating. The natural hormone is broken down within minutes. Semaglutide was engineered to last much longer, through two changes: one amino acid swap that protects it from the enzyme DPP-4, and a fatty side chain that lets it bind to albumin, the main protein in blood.
It’s also an approved medicine. Novo Nordisk sells semaglutide under the names Ozempic, Wegovy and Rybelsus. This product is not any of those. It is research material, sold by vial size, with no approval anywhere.
At Peptides Costa Rica it comes in three sizes, 10 mg, 20 mg and 30 mg, each as a lyophilized powder with a Certificate of Analysis for your batch. Delivery takes 2–4 business days from stock held inside Costa Rica, with no customs and no import fees
Semaglutide Price List in Costa Rica
Semaglutide pricing scales by vial size, and the cost per milligram drops significantly with the larger options. Here’s the full breakdown in USD:
- Semaglutide 10mg — $220 ($22.00 per mg)
- Semaglutide 20mg — $275 ($13.75 per mg)
- Semaglutide 30mg — $300 ($10.00 per mg)
The 30mg vial offers the strongest per-milligram value at less than half the cost per mg of the 10mg option. Combined with the 15% bulk discount on 5+ vials of the same size, a buyer ordering five 30mg vials would pay approximately $255 per vial — bringing the effective per-mg cost down to roughly $8.50.
Semaglutide Research Overview
Few molecules have a larger published record than semaglutide. It went through a large clinical development program at Novo Nordisk and was first approved by the US FDA in 2017. Since then it has been the subject of a very large clinical and pharmacological literature.
That literature describes the approved medicines, which are made under pharmaceutical manufacturing controls, prescribed by physicians and dispensed in finished, labeled form. It does not describe research material sold by vial size, and nothing on this page should be read as describing those medicines.
What this product offers a laboratory is a well-characterized reference peptide for work on the GLP-1 receptor, with a published structure and a batch certificate.
This product holds no registro sanitario with Costa Rica’s Ministerio de Salud. It is supplied as a research material and nothing else.
Why Researchers Choose Semaglutide
Semaglutide is one of the best-characterized peptides in existence, with a published structure, a single defined receptor and a clearly stated regulatory position.
01
Defined Structure
31 residues, molecular weight about 4,114, CAS 910463-68-2, confirmed on every batch certificate.
02
Single Receptor
Binds the GLP-1 receptor, a class B G protein-coupled receptor.
03
Engineered Stability
Resists DPP-4 and binds albumin, two well-documented design choices.
04
Reliable Availablity

Questions about Semaglutide pricing, vial sizes, batch documentation, storage, or delivery inside Costa Rica? Our team can confirm current stock, bulk pricing and what the Certificate of Analysis covers before you order.
What the Certificate of Analysis Covers
Semaglutide is a synthetic peptide with one sequence and one molecular weight, so it's tested the standard way. HPLC reports purity as a percentage of the main peak, and mass spectrometry confirms identity against the expected mass of about 4,114. One detail matters here. Because semaglutide carries a fatty side chain, a molecule missing that chain or carrying it in the wrong place would still look similar on a quick check. A good certificate should confirm the full, intact molecule by mass. The certificate also records appearance, water content and the batch number printed on the vial. Ask us for it before ordering.

Frequently Asked Questions
Semaglutide at Peptides Costa Rica is priced at $220 for a 10mg vial, $275 for a 20mg vial, and $300 for a 30mg vial. All prices are in USD and include local delivery in Costa Rica for any order over $200 — which means even a single 10mg vial qualifies for free shipping.
Yes. Order five or more vials of the same size in one order and a 15% discount applies automatically at checkout. Mixed sizes don't count toward the five.
Stock levels vary by vial size and update in real time on each product page. If a size shows as out of stock, you can reach our team directly to ask about expected restock timing or to be added to a notification list for your preferred size.
Yes — any order over $200 ships free anywhere in Costa Rica, which includes every Semaglutide vial size we offer. Delivery typically takes 2 to 4 business days, with no customs fees since all orders are fulfilled domestically.
They act on different receptors. Semaglutide binds only the GLP-1 receptor. Tirzepatide binds both the GLP-1 receptor and the GIP receptor, which responds to a second gut hormone. Both are long-acting modified peptides, and both are the active ingredients of approved medicines. Both are stocked here. See the Tirzepatide page for its own specifications.
Sealed vials are stored refrigerated at 2–8°C in lyophilized form, away from light and moisture. Freezing works for longer-term storage of the sealed powder. Once reconstituted, keep the solution refrigerated and avoid repeated freeze-thaw cycles. Storage conditions for your batch are printed on its Certificate of Analysis.
We accept SINPE Móvil, Zelle, and cash on delivery within Costa Rica. All prices on the site are listed in USD, but you can switch the currency toggle in the top corner to view amounts in Costa Rican colones (CRC).
Orders inside Costa Rica are typically delivered within 2–4 business days from the order date. You'll receive tracking once your package ships, and because everything is fulfilled locally, there are no customs delays or import fees.
