Product description
Lyophilized Tesamorelin peptide, supplied in 10mg and 20mg vial sizes, HPLC-verified purity with mass spectrometry identity confirmation. Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), engineered with a modified N-terminus for enhanced stability in laboratory applications compared to native GHRH.
In research settings, tesamorelin is studied for its role in growth hormone signaling pathways, specifically its interaction with GHRH receptors and downstream effects on the GH/IGF-1 axis. Researchers investigating endocrine regulation, body composition, and metabolic research models use this compound to better understand growth hormone secretagogue mechanisms. Its relevance extends to research on visceral fat metabolism and lipid regulation pathways within laboratory models.
Each vial is supplied in lyophilized (freeze-dried) powder form to preserve peptide stability during shipping and storage. After reconstitution with an appropriate diluent, solutions should be stored refrigerated and used according to your laboratory's standard handling protocols. See our Reconstitution Guide for detailed instructions.
This product is supplied strictly for laboratory research use only (RUO). It is not a drug, dietary supplement, or cosmetic, and is not intended for human or animal consumption, diagnosis, treatment, cure, or prevention of any disease. Purchasers must be qualified researchers, laboratories, or institutions acquiring this product for legitimate scientific research purposes only, in full accordance with our Terms of Service and RUO Disclaimer.

Tesamorelin reference information
Vial and presentation
Each Tesamorelin vial is supplied as lyophilized powder at 10mg / vial, sealed and labelled with catalogue code TSM-041. Vials are inspected before release and shipped in insulated packaging.
Purity and testing
Identity and purity are confirmed by third-party HPLC and mass spectrometry, with the result stated as ≥ 99% (HPLC). The full Certificate of Analysis for this lot is viewable on this page.
Storage
Store lyophilized material at -20 °C, protected from light and moisture. Once reconstituted for laboratory work, keep at 2–8 °C and avoid repeated freeze-thaw cycles.
Reconstitution
Reconstitution for laboratory work is performed with bacteriostatic water or another suitable diluent, added slowly against the vial wall and swirled rather than shaken. Record the volume used so concentrations remain traceable. Supplied for research use only; not for human or veterinary use.
