TESAMORELIN
Compound Overview
Tesamorelin is a synthetic 44-amino acid growth hormone-releasing hormone (GHRH) analog engineered to closely resemble endogenous human GHRH while incorporating structural modifications that enhance resistance to enzymatic degradation. By selectively binding to the growth hormone-releasing hormone receptor (GHRH-R), Tesamorelin has become an important investigational peptide for studying endocrine physiology, receptor pharmacology, peptide stability, and intracellular signaling mechanisms.
Researchers utilize Tesamorelin in laboratory settings to investigate growth hormone axis regulation, peptide-receptor interactions, pharmacokinetics, and molecular signaling pathways associated with GHRH receptor activation. Its high structural similarity to native GHRH, combined with improved stability, provides a valuable model for examining endocrine signaling and peptide engineering.
As an investigational peptide, Tesamorelin supports laboratory research involving molecular endocrinology, receptor biology, peptide pharmacology, and structure-activity relationship studies in controlled experimental models.

Product Documentation
Every batch of TESAMORELIN is independently tested and assigned its own lot number. When you request documentation, include the product name and lot number printed on your vial so we can send the COA, HPLC, and MS data specific to the batch in your hand — not a generic reference sample.

Laboratory Handling
Store refrigerated immediately upon receipt to preserve peptide stability. For extended laboratory storage, freezing at −20°C or below is recommended. Protect the lyophilized peptide from moisture, excessive heat, and direct light. Avoid repeated freeze-thaw cycles following reconstitution, as these may reduce peptide stability and biological activity. Allow the vial to equilibrate to room temperature before opening to minimize condensation, and always use sterile laboratory equipment together with appropriate aseptic laboratory techniques. This product is intended for use only by qualified research personnel operating in controlled laboratory environments.
