Janoshik Analytical report #109945 · sample submitted as Tesamorelin 5 mg.
Tesamorelin is a GHRH(1-44) analog bearing a trans-3-hexenoyl group on the N-terminal tyrosine. The acylation is the defining structural feature and the reason it appears in literature concerned with protease-resistant GHRH scaffolds.
Binds and activates the GHRH receptor with potency comparable to native hormone. The hexenoyl modification blocks N-terminal DPP-4 attack, extending in vitro and in vivo stability while preserving receptor recognition.
Listed fields describe where this sequence appears in published in vitro and preclinical literature. They are not indications, applications, or claims of effect.
Allow the vial to reach room temperature before opening to prevent condensation on the lyophilized cake. Add sterile or bacteriostatic water slowly down the inner wall of the vial, then let the powder dissolve without agitation; swirl gently if needed. Do not shake or vortex — shear forces denature peptide secondary structure and cause foaming that traps material on the stopper.
As a sealed lyophilized powder the material is stable for extended periods at -20 °C when kept desiccated and protected from light. Once in solution, stability shortens considerably: aqueous stocks are normally held at 2-8 °C for short term work or aliquoted and frozen for longer storage. Repeated freeze-thaw cycling is the most common cause of measurable potency loss.
Single sequence per vial, sealed under inert gas in USP Type I borosilicate glass with a butyl rubber stopper and crimped aluminium overseal. Each vial carries a printed PRIMEGEN LABS label with product name, strength, lot number, manufacture and retest dates, storage temperature and a QR code linking to the lot record. Vials ship in a rigid foam insert inside a protective mailer at ambient temperature.
