Tesamorelin

Tesamorelin is a synthetic Growth Hormone-Releasing Hormone (GHRH) analog presented as a lyophilized powder for laboratory research use. With a molecular formula of C221H366N72O67S and a molecular weight of approximately 5,135.8 Da, it is a structurally defined peptide verified by High-Performance Liquid Chromatography (HPLC) to a purity of ≥99%. Each vial is manufactured to consistent quality standards, making it a reliable reference compound for endocrinological and biochemical research programs.

Research background

Tesamorelin has been studied extensively in the context of GHRH receptor activation and the downstream stimulation of growth hormone (GH) release from pituitary cell models. In controlled in-vitro settings, it has been investigated as a tool for examining endocrine signaling cascades, with particular reference in the literature to metabolic regulation, lipolysis, and muscle-related signaling pathways. Its structural correspondence to endogenous GHRH makes it a well-characterised reference compound for comparative receptor-binding and functional assay work.

Reconstitution & handling

The lyophilized powder is reconstituted with bacteriostatic water (BAC water). Add an appropriate volume of BAC water directly to the vial, then swirl gently until the powder is fully dissolved — do not shake, as agitation can compromise peptide integrity. All handling should be carried out under aseptic conditions using appropriate laboratory technique. Single-use aliquoting is recommended to minimise freeze-thaw cycling of the reconstituted solution.

Storage & stability

The lyophilized product should be stored refrigerated and protected from light and moisture. For extended preservation prior to reconstitution, storage at or below freezing temperature is advisable. Once reconstituted, the solution should be kept refrigerated and used within a short window to maintain peptide stability and research-grade integrity.
