Sermorelin Price in Costa Rica
Sermorelin is available in a single 10mg vial at Peptides Costa Rica:
- Sermorelin 10mg — ₡68,172 (₡6,817.20 per mg)
With the 15% bulk discount on 5+ vials of the same product, the per-vial cost drops to ₡58,650 — a saving of ₡51,750 on a five-vial order (₡345,000 down to ₡293,250). Sermorelin is frequently paired with Ipamorelin in research protocols — combining a GHRH analog (Sermorelin) with a GHRP (Ipamorelin) produces synergistic GH release through dual-receptor pathway stimulation. Ordering both together in one order qualifies for free Costa Rica shipping.

How Sermorelin Is Identified
Accurate identification matters more than anything else on this page. Here is exactly what Sermorelin is, how to check it, and what comes with every vial.
Sequence
Sermorelin is a chain of 29 amino acids: Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-Gly-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-NH2. The chain ends in an amide group rather than a free acid, which is written as NH2 at the end.
Formula, Weight and CAS Number
The molecular formula is C149H246N44O42S, for a molecular weight of about 3,358 g/mol. The CAS number is 86168-78-7. Sermorelin is often supplied as its acetate salt, so check which form the certificate of analysis states for your batch.
Relationship to Human GHRH
Human GHRH is 44 amino acids long. Sermorelin is its first 29, the shortest section of the natural sequence that has been widely studied as a stand-alone peptide. Later research peptides were built from the same hormone: CJC-1295 from this 29-residue section, and Tesamorelin from the full 44-residue chain, each with changes of its own.
Batch Documentation
Every vial ships with the certificate of analysis for its batch, showing the batch number, the purity result, the test method and the test date. We can send it before you order.

Sermorelin Research Overview
Sermorelin’s story starts with the discovery of GHRH itself. In 1982, two research groups independently isolated and sequenced human GHRH, a 44-amino-acid peptide. Soon after, researchers found that shorter synthetic fragments of the chain could be made and studied on their own. The 1-29 fragment, with an amide at the end, became the best known of these. That fragment is Sermorelin.
Because Sermorelin is the shortest well-studied section of GHRH, it became a reference point for later work. Other research peptides in our catalog were designed from the same hormone. CJC-1295 starts from this same 29-residue section and swaps out individual amino acids, and Tesamorelin starts from the full 44-residue chain and adds a chemical group to one end. If you’re comparing these compounds, the sequence is the place to start. Their structures differ in specific, checkable ways, and our product pages for each one set out those differences.
The published literature on Sermorelin covers more than four decades. We don’t summarize study findings on this page, and nothing here describes what Sermorelin does in the body. For the literature, go to the primary sources: peer-reviewed journals and reference databases such as PubChem and PubMed. For this batch, start with its certificate of analysis.

Frequently Asked Questions
Sermorelin is a synthetic peptide made of 29 amino acids. Its sequence matches the first 29 residues of human growth hormone-releasing hormone (GHRH), with an amide group at the end of the chain. The molecular formula is C149H246N44O42S and the CAS number is 86168-78-7. We supply it in Costa Rica as a 10 mg freeze-dried powder, independently tested for every batch, for laboratory research only.
Sermorelin is priced at ₡68,172 per 10mg vial at Peptides Costa Rica, in USD. With a 15% bulk discount on orders of five or more vials, the per-vial cost drops to ₡58,650 — a saving of ₡51,750 on a five-vial order. A single Sermorelin vial qualifies for free Costa Rica shipping when paired with BAC Water or another product to cross the ₡92,000 threshold.
Both are built on the same 29-amino-acid section of human GHRH, but they are different molecules. Sermorelin is that section unchanged, with an amide at the end. CJC-1295 without DAC (also called modified GRF 1-29) swaps four of those 29 amino acids for different ones. CJC-1295 with DAC goes further and adds an extra lysine carrying a reactive chemical group to the end of the chain, which makes it a larger molecule with a different formula and weight. Because the structures differ, each one has its own formula and identification details, and each needs its own certificate of analysis. We supply all three, and each product page lists its own details. We don't compare how they perform.
They are different kinds of molecule. Sermorelin is a 29-amino-acid chain based on human GHRH. Ipamorelin is a much smaller synthetic peptide of five amino acids, belonging to a separate group of compounds known as growth hormone secretagogues, which are not based on the GHRH sequence at all. They have different formulas, weights and CAS numbers. We supply both, each with its own batch certificate, and each product page lists its identification details.
HGH (somatropin) is a protein of 191 amino acids, the full growth hormone molecule, and is registered as a prescription medicine in many countries. Sermorelin is a synthetic peptide of 29 amino acids based on a different hormone, GHRH. The two differ in size, structure, formula and regulatory status. Sermorelin is not registered with Costa Rica's Ministerio de Salud as a pharmaceutical product, and we supply it for laboratory research only. We don't compare what the two compounds do.
Sermorelin has been studied since the early 1980s, soon after human GHRH was first isolated and sequenced in 1982. It is one of the longest-studied fragments of that hormone, and later work on related peptides, including CJC-1295, builds on its sequence. The published record now spans more than four decades of peer-reviewed work. We don't summarize study findings on this page. For the literature itself, reference databases such as PubMed are the place to start, and for this product, the batch certificate is the place to start.
Unreconstituted Sermorelin vials should be stored refrigerated at 2–8°C in lyophilized (powder) form, protected from light and moisture. Freezing is suitable for long-term storage. Once reconstituted with bacteriostatic water, keep the solution refrigerated and use within the timeframe outlined in your research protocol. Avoid repeated freeze-thaw cycles, which can degrade peptide stability.
Orders inside Costa Rica are typically delivered within 2–4 business days. You'll receive tracking once shipped — no customs delays or import fees.
