What is Sermorelin, and what is it used for?
Sermorelin is also listed and searched as Sermorelin Acetate, Sermorelin peptide, GRF 1-29. They all mean the same compound. Supplier lists write it as Sermorelin peptides or peptide Sermorelin as well; every one of those is this record. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C149H246N44O42S, average mass 3357.9 g/mol (PubChem CID 16132413). This product is the acetate salt, so a lot certificate reports the salt rather than the free peptide figures above.
A man-made peptide matching the first 29 building blocks of growth-hormone-releasing hormone.
It works on the GHRH receptor. Those first 29 building blocks are the shortest piece of the natural hormone that still works on the receptor, which is why the class is built on that particular cut.
An older clinical and hormone-research record exists, mostly about how the GHRH receptor behaves and about using the peptide as a diagnostic tool.
What is sold here is a research chemical, not a drug product. Sermorelin, CJC-1295 and Mod GRF(1-29) are close relatives and get mixed up constantly in commercial listings, so check the certificate for which molecule is actually in the vial.

Where to buy Sermorelin: what to check before you order from anyone
Where to get Sermorelin, and how to buy Sermorelin online
Sermorelin for sale, or Sermorelin peptide for sale, means this page: one record, 2 sizes. You can buy Sermorelin online here with guest checkout, and purchase Sermorelin or order Sermorelin in any size below; verified in-stock orders placed before 12 PM Pacific are dispatched the same day. If the question is where to get Sermorelin or how to get Sermorelin, the answer for a US laboratory is a supplier who publishes the certificate before you pay, which is the first of the five checks that follow.
Before ordering Sermorelin from anyone, us included, run the 5 checks on verifying a certificate; the first is that the report resolves on the laboratory's own site, and a seller who cannot pass them is asking for the trust a certificate exists to replace.
Sermorelin Acetate reviews
No customer review of Sermorelin Acetate has been published yet, so there is no star rating here; when real ones exist the number will be the arithmetic of what people wrote. Ordered this record? Leave a review. A person reads every one before it appears.
Sermorelin capsules, sublingual or oral form? What this vial is, and is not
Search results for Sermorelin also show capsules, sublingual, oral form products, under listing titles such as sermorelin tablets, sermorelin nasal spray, oral sermorelin, sermorelin pills, sermorelin oral, sermorelin sublingual. Those are finished consumer goods made and marketed by other companies, and none of them is what this page sells. This record is freeze-dried Sermorelin in a sealed glass vial, 5mg and 10mg, with a lot certificate, supplied for laboratory work. Its certificate describes that powder, not a capsule, spray or cream, which carry other ingredients and sit under different rules.
Sermorelin vs Ipamorelin and CJC-1295 (no DAC): different molecules, separate records
Sermorelin vs Ipamorelin, or Ipamorelin vs Sermorelin, is the comparison people search most, with CJC-1295 (no DAC) close behind, and they are not the same thing. Each is a different molecule with a different formula, mass and research record, and each has its own certificate here. Sermorelin ipamorelin blend is searched too; no such blend is sold here, each is its own record with its own certificate, and a certificate for a blend from anyone else reports on the mixture, not on either compound alone.

The Sermorelin certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. The figure usually quoted for Sermorelin is 3,357.9 g/mol for C149H246N44O42S, from PubChem CID 16132413, and it does not describe what is in this vial. This product is the acetate salt, so a lot certificate reports the salt rather than the free peptide figures above. So the mass on the lot certificate is the one to read; a listing that quotes the published figure for this material is quoting the wrong molecule.
Listings elsewhere describe Sermorelin Acetate as an acetate, an arginate salt or an N-acetyl form. Those are different chemical forms with different masses, and a certificate identifies which one was actually tested. The form of the lot on this page is whatever its certificate states; it is not assumed from a listing name, ours included.
Sermorelin Acetate certificates post here and in the certificate index when Kovera Labs reports on the lot.
Is Sermorelin legal? FDA status, and what this listing is
FDA status, and what this listing is Not an FDA-approved drug product
The FDA has not approved this compound for anything, and nothing in this catalog is a medicine.
Status verified 2026-08-25. Check the primary source before relying on this summary.
Whether Sermorelin is legal depends on what it is being used for and where. It is sold as laboratory material under the research-use restriction below. Being listed is not an approval, and not a claim that it is safe, effective or right for any purpose. LabFirst is not a pharmacy or a compounding facility, this vial is not a compounded medicine, and no prescription is involved, because it is not sold for use in anyone. Sports bodies keep their own prohibited lists; whether a substance is banned in competition is a question for the relevant anti-doping authority, not for a supplier.
Sermorelin research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
Sermorelin is the first twenty-nine building blocks of human growth-hormone-releasing hormone. That piece was found to be the shortest one that still triggers growth hormone release in full, which is why the whole class is built on it rather than on the complete 44-building-block hormone. It works on the GHRH receptor on the pituitary, so like tesamorelin it acts one step early and leaves the gland’s own feedback in place.
Its defining practical problem is that it falls apart fast: the DPP-4 enzyme cuts it near one end, and it survives in the blood for minutes. Every other GHRH copy in this catalog is an attempt to fix that one problem. Tesamorelin adds a chemical group to the vulnerable end. CJC-1295 swaps out the fragile building blocks and adds a part that grips albumin. Sermorelin is the plain starting point all of them were built from.
| Reported observation | Model | Source |
|---|---|---|
| Three modified versions of the 29-building-block peptide held up better against the DPP-4 enzyme in the test tube than the plain peptide did, and the best of them produced four times as much growth hormone over two hours as the unmodified version. That comparison is the clearest published measure of what the fragile parent sequence costs. | in vitro DPP-IV stability, cultured rat anterior pituitary cells, and subcutaneous administration to Sprague Dawley rats | Jette and colleagues, Human growth hormone-releasing factor (hGRF)1-29-albumin bioconjugates activate the GRF receptor on the anterior pituitary in rats: identification of CJC-1295 as a long-lasting GRF analog, Endocrinology (2005) |
| Given into a vein in human volunteers, the peptide produced a quick rise in growth hormone, but also a small short-lived rise in prolactin, and it amplified the TSH response to a separate hormone beyond what that hormone produced on its own. The authors conclude the fragment has moderate prolactin-releasing activity alongside its growth-hormone-releasing activity. | human volunteers, combined anterior pituitary provocation testing | Looij and colleagues, The interaction of growth hormone releasing hormone with other hypothalamic hormones on the release of anterior pituitary hormones, Clinical Endocrinology (1986)Worth reading against the common claim that this compound acts only on growth hormone. |
Open questions. Sermorelin is often described as acting on growth hormone only. The 1986 human work above found moderate prolactin release and amplification of TSH release, so that description is an approximation rather than an established fact, and it is exactly the sort of caveat that vanishes from supplier copy. The compound was approved and sold as Geref and has since been withdrawn, so there is no current official reference product behind the name. Most of the primary human work dates from the 1980s and 1990s, before modern trial standards.
Anyone comparing this with the longer-lasting relatives should keep the timing in view: the parent sequence is cleared in minutes, and that is a property of the molecule, not a packaging problem a supplier can fix.
Each row above describes an observation in the stated model. None of it describes what Sermorelin Acetate would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store Sermorelin: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the Sermorelin Acetate sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
