Sermorelin, on this catalog, is a lyophilized GHRH fragment sold for laboratory work. The shop URL is Sermorelin 10mg. This page is the sequence note. The paired comparison is sermorelin versus tesamorelin. Neither page is a method. Price and stock stay on the listing.

Sequence

Human growth hormone-releasing hormone was reported as a 44-residue peptide. Guillemin and colleagues described that hormone from a pancreatic tumour extract in Science in 1982 (PMID 6812220). Sermorelin, as this site's comparison page records, is the N-terminal 29 residues as a C-terminal amide: 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. Twenty-nine residues, no fatty acyl tail, and an amide at the C terminus are the identity marks. A calculated mass for those 29 residues will not match a 44-residue analogue.

Count the residues before you compare a PDF. The string above is the comparison-page record this note repeats so a receiver does not have to reconstruct it from the product name. It is still not a substitute for the mass printed on the lot file. If the report's mass does not fit that amide, hold the vial. Do not "correct" the file by dropping residues until the numbers agree.

The receptor class is the GHRH receptor, not GHSR-1a. The mechanism note is GHRH analogs. The glossary lines are GHRH, secretagogue, sequence, and amidation. Ipamorelin is a different pentapeptide filed under GHSR literature. CJC-1295 without DAC is a different GHRH analogue on its own blend listing. Do not borrow one certificate for another. The blend note is CJC-1295 without DAC and ipamorelin. It is not this 29-residue page.

What a fragment paper is for

Izdebski and colleagues compared analogues against hGH-RH-(1-29)-NH2 in a superfused rat pituitary cell system (PMC41809). This note cites that paper only for the existence of the 29-residue amide as a reference peptide in receptor work. It does not copy potency ratios, and it does not turn a pituitary-cell figure into a catalog claim. The useful laboratory point is the length and the amide.

Tesamorelin keeps a 44-residue frame and adds a trans-3-hexenoyl group. Its note is the tesamorelin laboratory note. Length is the first difference. The acyl group is the second. Kisspeptin-10 is a different decapeptide at a different receptor. The gelation note that mentions tesamorelin and kisspeptin is not a sermorelin sequence card.

Analytical documentation

A catalog name is not an identity test for Sermorelin 10mg. Open how to read a peptide Certificate of Analysis and the purity-versus-mass note. The short version of the same check is the COA verification FAQ. Copy the task identifier from the Janoshik URL on verify.janoshik.com or janoshik.com, the sample name, the date, the mass, the purity figure and its method, and any endotoxin number with its unit. A photograph of a report is not the report. Cap colour and the labeled milligram size are lot-specific. A file for a different size does not document this container.

Chromatographic area percent and mass identity answer different questions. Read chromatogram, mass spectrum, purity versus identity, and molecular weight before you file one number as both answers. Salt form, when the PDF names trifluoroacetate or acetate, is a third line. The glossary entries are TFA salt and acetate salt. This catalog does not publish a house factor that converts a salt weight into a free-base figure. If the report is silent, leave the salt line blank. Net peptide content is recorded only when the PDF states it.

The public certificates library does not currently list a sermorelin row. Open the certificates library and confirm the absence rather than borrowing a tesamorelin, ipamorelin, or CJC blend file. If a sermorelin report is added later, match its sample name and the 10 mg size to the vial in hand. Until that row exists, the absence is part of the receiving log.

The receiving log for this material is ordinary and short. Write the product name, the labeled amount, the cap colour if one is printed, the lot number or batch code, the receipt date, the storage location, the report URL, and whether the sample name matched the container in hand. Quarantine the container when the seal is broken, the solid looks wet, the label does not match the packing list, or the report link will not open. The Burnaby desk can look up an order number. It cannot reconstruct identity from a container that has already been relabeled by hand.

Handling and Canada fulfilment

The solid is stored sealed because residual water can cleave peptide bonds and can collapse a cake. The format primer is lyophilized research peptides. Open the parcel the day it arrives. Do not leave it in a vehicle, an outdoor box, or on a loading dock. Move the closed vial into controlled storage and follow the temperature on the product note. A cake that looks different after a cold Canada Post parcel is not an identity test. Do not heat a very cold vial. The receiving note is peptide storage for Canadian laboratories. This page does not list a diluent volume. If a laboratory SOP calls for a separate diluent, bacteriostatic water and reconstitution diluent are glossary entries for that reagent, not a volume for this vial.

Paid orders ship on Canada Post Xpresspost inside Canada after Interac e-Transfer. The public desk is 4309 Canada Way, Burnaby, BC. The label sender is a Port Moody, B.C. PO Box for the carrier account. Put the order number in the Interac message field so the payment can be matched to the emailed invoice. Tracking is emailed after a scan, typically within one business day of payment. Canada Post does not operate on weekends or statutory holidays, so a Friday payment can sit until the next operating day. Estimates are not guarantees. Those facts are restated on the shipping FAQ and the payment FAQ. The procurement note is Canada laboratory procurement. The shop URL is Sermorelin 10mg.

A research-use-only container is not a clinical-trial drug product and it does not carry a Drug Identification Number. The distinction is on the catalog-versus-trial FAQ. What the research-use-only phrase does and does not do, including the point that the phrase is not by itself a Health Canada authorization, is on the research-use-only FAQ. This page is not legal advice. Domestic Xpresspost keeps the parcel on a Canadian carrier. It does not remove research-use-only limits, and it does not make a catalog solid into an authorized drug.

A tesamorelin report, when the library publishes one, lives at the tesamorelin anchor. That mass includes fifteen further residues and a hexenoyl group. It cannot document this 29-residue amide.

The category index that currently lists this material is the GHS category. The category also lists ipamorelin and the CJC-1295 without DAC blend. Those are different sequences. The menu is not a statement that they share a receptor or a certificate.

Frequently asked questions

How long is the sermorelin sequence on this note?

Twenty-nine residues, the N-terminal portion of the 44-residue human GHRH sequence, written as a C-terminal amide. The comparison with tesamorelin is a separate page. The lot mass still has to be read from the PDF.

Does sermorelin use the same receptor as ipamorelin?

No. This note files sermorelin with GHRH-receptor literature. Ipamorelin is discussed on this site as a GHSR ligand. The receptors are different, and the certificates are different.

Where is the sermorelin shop URL?

The 10 mg listing is /shop/sermorelin-10mg. This article is the laboratory note. Price and stock stay on the listing.

What does research use only mean for this GHRH fragment?

The lyophilized solid is sold for laboratory work. The label is not a Drug Identification Number and this page does not give personal-use steps.
