What Tesamorelin is
Tesamorelin keeps all 44 residues of human GHRH and adds a trans-3-hexenoyl group to the N-terminus, which slows enzymatic breakdown.
That makes it structurally different from CJC-1295, a shortened 29-residue GHRH fragment. Researchers use tesamorelin as the approved benchmark when comparing GHRH analogues.
What the research literature studies
- GHRH-receptor binding and cAMP signalling
- Effect of N-terminal modification on enzymatic stability
- Comparison of full-length and truncated GHRH analogues
Evidence rating: 5/5
Approved drug, phase 3 trials. Approved medicine backed by phase 3 trials in its labelled indication. See our methodology for how levels are assigned.
- Approval covers one indication and is not evidence for any other use.
- Long peptides are harder to synthesise cleanly, so intact-mass confirmation matters.
Regulatory status
Tesamorelin is FDA-approved as a prescription medicine for one indication. That approval covers one use in one region. Research-grade material is not that medicine and must not be used in people or animals.

Tesamorelin FAQ
How does tesamorelin differ from CJC-1295?
Tesamorelin is the full 44-residue GHRH sequence with an N-terminal hexenoyl group. CJC-1295 is based on the first 29 residues. Both act on the GHRH receptor. See the comparison page.
Where can I buy Tesamorelin for research?
Nordapep does not currently list Tesamorelin. You can ask Nordapep about availability, or compare related compounds that are in stock.
Is Tesamorelin approved?
