Tesamorelin research peptide: product overview

Lyophilized Tesamorelin research 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.

Frequently Asked Questions

What is Tesamorelin used for in research?
Tesamorelin is a synthetic growth hormone-releasing hormone (GHRH) analogue consisting of a 44-amino acid sequence with a trans-3-hexenoic acid modification. In laboratory research, it is studied for its mechanisms regarding endogenous GH stimulation, cellular metabolism, and adipose tissue pathways.

How should research Tesamorelin be reconstituted and handled?
For research handling, slowly add sterile bacteriostatic water down the inside glass vial wall. Gently roll or swirl the vial until dissolved; never shake vigorously, as mechanical shear can disrupt peptide conformation. Once reconstituted, maintain refrigeration at 2°C to 8°C.

Are batch-specific COAs available before I buy Tesamorelin?
Yes. Downloadable Certificates of Analysis (COAs) for Tesamorelin are accessible on this page. They list the HPLC purity and mass spectrometry results for the tested lot.

Choosing and documenting your research material

Select the 10mg or 20mg option using the size selector above before adding the product to your cart. Review the price shown for your selected variation and confirm the vial size in your order details. Keeping the product name and selected size together in your purchasing records helps distinguish this material from other compounds or quantities used by your laboratory.

The product specifications, analytical report, and research background serve different purposes. Specifications describe the listed material, while the certificate provides the results for the sample identified by the laboratory. The linked research overview gives scientific context. Read the source documents alongside the product summary when deciding whether the available information meets your laboratory’s procurement requirements.

Finding the certificate and supporting information

The certificate button above opens the published Tesamorelin PDF directly. Keep a copy with your laboratory records and use reference 210665 when discussing that report. The separate verification link takes you to the testing laboratory’s certificate verification page. These links make it easier to locate the original documentation rather than relying only on a short product summary.

For questions about available documentation or a particular order, use our contact page. Include the product name, selected vial size, and the report reference where relevant so your question can be matched to the appropriate information.
