Tesamorelin, on this catalog, is a lyophilized GHRH analogue sold for laboratory work. The shop URL is Tesamorelin 10mg. This page is the structure note. It is not a finished-product label and it is not a method. Price and stock stay on the listing.

Structure

Tesamorelin keeps the 44-residue human GHRH frame and adds chemistry at the N terminus. Ferdinandi and colleagues discussed the analogue TH9507 in Basic and Clinical Pharmacology and Toxicology in 2007 (PMID 17214611). This page uses that citation for the structure already stated on the comparison page: a trans-3-hexenoyl group on tyrosine-1 of GHRH(1-44) amide. The extra fifteen residues beyond sermorelin are Gln-Gln-Gly-Glu-Ser-Asn-Gln-Glu-Arg-Gly-Ala-Arg-Ala-Arg-Leu. The hexenoyl group shifts the mass again. Length alone is enough to keep the certificates apart.

Falutz and colleagues, in the New England Journal of Medicine in 2007, name tesamorelin as a synthetic GHRH(1-44) analogue with a trans-3-hexenoyl group added at the N terminus (PMID 18057338). This note cites that sentence for chemical identity. It does not restate the trial's endpoints, and it does not assign the catalog vial the role of the material dispensed in that study. A research-use-only solid is not a clinical-trial drug product.

Two checks follow from that structure. First, a 29-residue calculation will not match. Second, an unmodified 44-residue calculation that omits the hexenoyl group will not match either. The lot file has to carry the mass the laboratory actually measured. This page does not publish a house dalton figure for the acyl group. If the PDF is silent, record the silence. Do not fill the blank from a secondary blog.

Receptor class and the gelation note

The receptor class is the GHRH receptor. Read GHRH analogs and the GHRH glossary. N-terminus is the glossary line for the end that carries the hexenoyl group. Sermorelin is the 29-residue amide without that tail. Its note is the sermorelin laboratory note. A separate page, why sequences can gel, records a physical-chemistry observation about wetting. That page is not a preparation method and it does not replace the mass on the lot file. Kisspeptin-10 can appear on that gelation page. It is a different sequence, documented on the kisspeptin-10 laboratory note.

Analytical documentation

A catalog name is not an identity test for Tesamorelin 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 library row for a published tesamorelin lot is Tesamorelin 10mg in the certificates library. Match the sample name and the 10 mg size. A sermorelin file would not document this analogue even if the library later adds one, because the length and the acyl group differ.

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 Tesamorelin 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.

Ipamorelin and the CJC-1295 without DAC blend are GHS-menu neighbours. They are not this 44-residue acyl analogue. Keep their reports on their own sample names.

The category index that currently lists this material is the GHS category. Interac message-field matching and Xpresspost transit expectations stay on the procurement note already linked above. The category name is not a receptor assignment.

Frequently asked questions

What structural mark separates tesamorelin from sermorelin?

Tesamorelin keeps a 44-residue GHRH frame and adds a trans-3-hexenoyl group on the N-terminal tyrosine. Sermorelin is the 29-residue amide without that acyl group. The two masses are not interchangeable.

Is the catalog tesamorelin vial the finished product studied in the 2007 paper?

No. The paper names the analogue. The BlueNex Labs listing is a lyophilized research solid with its own lot file. It is not a clinical-trial supply and it is not an authorized drug.

Which handling note covers a tesamorelin gel observation?

The separate page on tesamorelin and kisspeptin gelation records a physical-chemistry observation. It is not a preparation method, and it does not replace this sequence note.

How is a tesamorelin order paid and shipped?

Interac e-Transfer to the address on the invoice, with the order number in the message field, then Canada Post Xpresspost inside Canada. The public desk is in Burnaby.
