What is tesamorelin?
Tesamorelin is a synthetic 44-amino-acid peptide analogue of human growth hormone-releasing hormone (GHRH). In the laboratory it is used in in-vitro receptor-signalling assays and peptide stability studies.
How does tesamorelin differ from native GHRH?
It has the same 44 amino acids as human GHRH(1-44), with a C-terminal amide, plus a trans-3-hexenoyl group on the N-terminal tyrosine. This modification is reported to make it more resistant to cleavage by dipeptidyl peptidase-4 (DPP-4).
