Product description
A synthetic analogue of growth hormone releasing hormone. Supplied lyophilised in a 10mg vial.
Research context
Tesamorelin is used in laboratory receptor binding and signalling studies at the GHRH receptor. Unlike the secretagogues it acts on the releasing hormone receptor rather than the ghrelin receptor, which is the distinction that makes it useful in comparative work. Also referenced as TH9507.
Handling notes
Reconstitute with bacteriostatic water added slowly against the wall of the vial. This is a large peptide and benefits from time rather than agitation. Store frozen and protected from light, aliquot after reconstitution.
Worth knowing
The mechanistic difference from ipamorelin is the reason to hold both in a comparative study, and the reason results between them are not directly interchangeable.
Documentation
This batch ships with its own certificate of analysis showing HPLC purity and mass spectrometry identity confirmation. The batch reference is recorded against your order, so a result generated months from now can be traced back to this specific lot.
Intended use
Supplied strictly for laboratory research use. Not a medicine. Not for human or veterinary consumption, and not for any diagnostic or therapeutic use.
Research background
The short version
A modified version of growth hormone releasing hormone. It acts one step further up the chain than the secretagogues, on a different receptor.
Tesamorelin is a synthetic analogue of growth hormone releasing hormone. It acts at the GHRH receptor rather than the ghrelin receptor, which is the mechanistic distinction that makes it useful alongside compounds like ipamorelin.
Where it came from
Developed by Theratechnologies under the code TH9507 and approved in some jurisdictions as Egrifta for a specific indication.
How it is thought to work
Binds the GHRH receptor on pituitary somatotrophs. A trans-3-hexenoyl modification at the N terminus improves stability relative to native GHRH.
The distinction from ghrelin receptor agonists matters in study design: the two act on different receptors and results are not interchangeable.
What it is studied for
What the published research found, and what it was tested in. We list the model against each one so you can judge how far the findings go.
- GHRH receptor pharmacology Binding and activation at the receptor. What they found Binding and activation at the GHRH receptor confirmed in receptor assays. Tested in Receptor binding assays, cell culture
- Stability studies How the structural modification affects degradation relative to native GHRH. What they found The trans-3-hexenoyl modification at the N terminus improves resistance to enzymatic degradation relative to native GHRH. Tested in In vitro
- Clinical characterisation Approved for a specific indication, so a human dataset exists. What they found Approved for a specific indication in some jurisdictions, so a controlled human dataset exists. That dataset concerns the approved indication only. Tested in Human clinical trials

Questions about this compound
How should Tesamorelin 10mg be stored?
Store the sealed vial at -20C, protected from light. Sealed and held at that condition it carries a shelf life of 24 months from date of manufacture, sealed from the date of manufacture. Once reconstituted, shelf life shortens considerably and the solution should be aliquoted before freezing rather than thawed repeatedly.
How is Tesamorelin 10mg reconstituted?
Soluble in bacteriostatic water. Add the solvent slowly down the inside wall of the vial rather than directly onto the material, then swirl gently to dissolve. Do not shake, vortex or sonicate to speed it up. A cloudy solution that will not clear usually means the wrong solvent rather than a poor batch.
What purity is this batch and how is it verified?
This item is supplied at 99%+ (HPLC), measured by high performance liquid chromatography. Identity is confirmed separately by mass spectrometry. Both results appear on the certificate of analysis for the batch you receive, not for a previous lot.
Can I see the certificate of analysis before ordering?
Yes. It is linked in the documentation section of this page. If no certificate is shown against this listing, ask before ordering rather than after.
Is Tesamorelin 10mg the same as the other names it appears under?
Yes. Tesamorelin 10mg also appears in the literature as Tesamorelin acetate, TH9507, Egrifta. They refer to the same compound, which is worth knowing when searching for prior work because results are split across the names.
Can this be used in humans or animals?
No. This is supplied strictly as a laboratory reagent for in vitro research. It is not a medicine, it is not licensed for human or veterinary use, and it should not be administered to a person or an animal. We do not provide dosing or administration guidance.
