Tesamorelin is a lab-made copy of GHRH, the natural hormone that tells your body to release growth hormone, with a small tweak that makes it last longer. It was developed by Theratechnologies, a Montreal company, and it’s one of the best-studied peptides we carry. It comes as a freeze-dried powder in a 10 mg vial.

Tesamorelin — compound background
Full-length 44-residue GHRH analogue with trans-3-hexenoic acid modification
Tesamorelin is the complete 44-amino-acid sequence of human growth hormone-releasing hormone with a trans-3-hexenoic acid group attached at the N-terminus. That modification exists for one reason: native GHRH is cleaved almost immediately by dipeptidyl peptidase-4 at the N-terminal end, and the hexenoyl group blocks that cleavage.
Solubility & reconstitution
At 44 residues this is one of the longest chains in the catalogue and behaves accordingly — dissolution is slower than for short peptides and the material benefits from patience rather than agitation. The N-terminal acyl group adds modest hydrophobicity, so gentle swirling over several minutes is the correct approach.
Storage
Sealed at -20 °C. Longer chains generally have less thermal margin than short peptides; minimise ambient exposure. Refrigerate at 2–8 °C. Longer peptides have more potential degradation sites simply by virtue of length.
Commonly worked with for 2–3 weeks at 2–8 °C.
Stability
Do not freeze reconstituted material. At this chain length, interfacial aggregation during freezing is a real risk.
Reading the Certificate of Analysis
Confirm the mass near 5135 Da, and specifically confirm the N-terminal modification is present — a des-hexenoyl species would be 96 Da lighter and represents material lacking the entire stability rationale of the molecule. For a synthesis this long, review the chromatogram for closely eluting deletion sequences.
