Tesamorelin

Description

Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone (GHRH), used in laboratory work as a tool compound for studying the somatotropic axis and GHRH receptor signaling. Pure Peptides Canada supplies it as a lyophilized research reagent to a defined specification, shipped domestically to labs and qualified research buyers looking for research peptides in Canada without cross-border customs delays. It is sold strictly for in-vitro laboratory research.

Overview

Each unit is a sealed vial of lyophilized (freeze-dried) Tesamorelin powder, available in 10mg or 20mg fill weights and as single vials or boxes of ten for larger study designs and repeat protocols. The powder is intended for reconstitution in a suitable research solvent chosen by the investigator, at whatever working concentration the assay requires. Freeze-drying is the standard format for peptide reagents because a dry solid is far more stable in transit and storage than a solution, and it lets the end user control the buffer, concentration and aliquoting rather than inheriting someone else’s. Every lot is analyzed by an independent laboratory before release, and the certificate of analysis you receive corresponds to the specific batch in your hands.

What it is known for

Tesamorelin is recognized in the peptide literature as a stabilized GHRH(1-44) analogue — a growth hormone-releasing factor sequence modified at the N-terminus to resist rapid enzymatic degradation, which is what distinguishes it from unmodified GHRH fragments in a research setting. Buyers choose this listing over unverified sources because the purity and identity data comes from a third-party analytical lab rather than the seller’s own claim, and because the batch number on the vial matches the batch number on the COA. It sits in the Growth & Signaling category alongside other secretagogue-class research compounds.

Key features

• Third-party HPLC purity testing (Janoshik) — Purity is verified by an independent analytical lab, not asserted in-house, so your quantitation and dose-response work rests on a number someone outside the transaction stands behind.
• Mass spectrometry identity confirmation — Confirms the molecular mass matches the intended Tesamorelin sequence, ruling out the mislabelled or substituted material that undermines an entire experimental run before it starts.
• Batch-matched certificate of analysis — The COA corresponds to your specific lot, which is what a supervisor, grant auditor or journal reviewer will ask to see when you document reagent provenance.
• Lyophilized powder format — A dry solid tolerates shipping and cold storage far better than a pre-made solution, and lets you select your own solvent, buffer and working concentration.
• Two fill weights — 10mg and 20mg — Match the vial to the scale of the work: smaller fills reduce waste and repeated freeze-thaw on pilot studies, larger fills cut per-milligram handling on extended protocols.
• Single vials or boxes of ten — Ten-packs give you consistent material across a full study arm, so lot-to-lot variation is not a variable you have to control for mid-experiment.
• Cold storage and cold-chain handling — Peptide reagents degrade with heat and humidity; storing and shipping cold protects the specification you paid for until the vial reaches your bench.
• Shipped from Canada, tracked nationwide — No international customs hold, no border seizure risk, and a tracking number so you can plan a reconstitution date around a known arrival.

Benefits

• Independent analytical data means less time spent qualifying an incoming reagent and more confidence that an unexpected result reflects biology, not the vial.
• Documented, batch-traceable provenance supports reproducibility and stands up to internal QA or institutional record-keeping.
• Domestic shipping keeps lead times short and predictable compared with overseas orders.
• Choosing your own solvent and concentration means the reagent fits your assay conditions instead of forcing a compromise.
• Bulk boxes let a multi-arm or long-running study run on a single consistent lot.
• Discreet packaging and tracked delivery for straightforward receipt at a lab, university or business address.

Specifications

Typical applications

• In-vitro investigation of GHRH receptor binding and downstream signaling
• Comparative studies of GHRH analogues and growth hormone secretagogue-class compounds
• Somatotropic axis and endocrine signaling research in cell-based models
• Analytical method development, reference material for HPLC or LC-MS work
• Assay development and dose-response characterization in research settings

Important information

• Research use only. This product is not a drug, supplement, food or cosmetic, is not intended to diagnose, treat, cure or prevent any disease, and is not for human or veterinary use, ingestion or administration.
• Keep vials cold and sealed until use, and protect from light and moisture; lyophilized peptides are hygroscopic and draw water from room air once opened.
• Allow a vial to reach room temperature before breaking the seal, to limit condensation on the cake.
• Reconstitute in a solvent appropriate to your assay and downstream analysis; the reagent is supplied dry so that choice remains yours.
• Aliquot after reconstitution rather than repeatedly freezing and thawing a single vial — freeze-thaw cycling is a common and avoidable cause of peptide degradation.
• Confirm the batch number on the vial matches the certificate of analysis on file for your lot, and retain the COA with your experimental records.
• Handle with standard laboratory PPE and dispose of according to your institution’s protocols.

Common questions

What is Tesamorelin used for in research?

It is a synthetic GHRH analogue used as a tool compound in laboratory studies of growth hormone-releasing hormone receptor signaling and the somatotropic axis. It is supplied for in-vitro research only, with no human or veterinary application.

Can I see the certificate of analysis before I order?

Yes — a batch-matched COA is available, showing HPLC purity and mass spectrometry identity from an independent third-party lab. Ask for the current lot’s documentation and check that the batch number matches the vial you receive.

Who performs the testing?

Analysis is carried out by Janoshik, an independent third-party analytical laboratory, rather than in-house. Purity is assessed by HPLC and identity confirmed by mass spectrometry.

Should I choose 10mg or 20mg vials?

Match the fill to your working scale. A 10mg vial suits pilot work or smaller assay volumes and limits waste once reconstituted; 20mg reduces the number of vials to handle on larger or longer protocols. Boxes of ten are the better choice when a whole study should run on one consistent lot.

How is it shipped and how should I store it?

It ships cold and discreetly from within Canada with nationwide tracking. Store the sealed lyophilized vial cold on arrival; after reconstitution, aliquot and store according to your lab’s peptide handling protocol to avoid repeated freeze-thaw.

Does it come reconstituted or with a solvent?

No. It is supplied as a dry lyophilized powder so you can select the solvent, buffer and concentration your experiment calls for. Reconstitution solvent is not included.

In summary

A lyophilized Tesamorelin reagent with independent HPLC purity and mass-spec identity data behind it, batch-matched paperwork, and cold, tracked shipping within Canada. Choose the fill weight and pack size that fits your study, keep the COA with your records, and use it strictly for in-vitro laboratory research.
