Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH), consisting of 44 amino acids with a molecular formula of C₂₂₁H₃₆₆N₇₂O₆₇S and a molecular weight of 5,135.9 g/mol. It is also known by the research designation TH9507. The compound is identified by CAS number 218949-48-5.

Structurally, tesamorelin is identical to the first 44 amino acids of naturally occurring human GHRH (which is itself 44 amino acids long), but with one modification: a trans-3-hexenoic acid group is attached to the tyrosine at position 1. This chemical addition was designed to increase the molecule’s stability and resistance to enzymatic breakdown. The compound is classified as a GHRH analog — a synthetic version of a naturally occurring signaling peptide. It is supplied as a lyophilized white to off-white powder, soluble in water, and requires refrigeration after reconstitution.
