Tesamorelin is a synthetic 44-amino acid analogue of growth hormone-releasing hormone (GHRH), identical to native GHRH(1-44) except for a trans-3-hexenoic acid substitution at the N-terminus, which improves stability against dipeptidyl peptidase IV. It is supplied for in vitro neuroendocrine and receptor signalling research and has been studied in published literature. The 5 mg format is suitable for laboratory research programmes. Supplied as lyophilised powder with certificate of analysis. For research use only — not for human or animal consumption.

Every batch is verified at the manufacturer and re-tested when received in the UK. We send batches to a third-party lab where results cannot be manipulated — we do not rely on supplier testing or CoAs alone, so you get what you pay for. Each batch is independently analysed and supplied with a Certificate of Analysis (CoA) detailing purity, identity, and analytical method used. Batch-coded stock ensures full traceability from production to dispatch. Stock is held in laboratory-grade temperature-controlled storage and prepared using controlled thawing before dispatch. See our About page for full details. Additional documentation is available upon request for institutional procurement.
