What Is Tesamorelin?

Last reviewed: 17 August 2026

Tesamorelin lyophilised reference material vial

Tesamorelin is a synthetic analogue of human GHRH(1-44) carrying a trans-3-hexenoyl modification at the N-terminus that improves stability against enzymatic breakdown. It is studied as a receptor-level tool for probing endogenous growth-hormone release.

How is tesamorelin classified?

A full-length GHRH analogue — longer than the GHRH(1-29) fragments used elsewhere in this class — grouped with secretagogue-adjacent compounds that act upstream of the pituitary rather than supplying exogenous growth hormone.

How is its mechanism studied?

  • GHRH receptor binding and cAMP signalling in pituitary cell models.
  • Endogenous GH pulse characteristics, studied as a physiological readout.
  • IGF-1 response as a downstream endpoint in study designs.

What kind of research exists?

Tesamorelin has more human clinical literature than most peptides in this library, alongside the standard receptor-pharmacology base. That relative depth is why it is often used as a reference analogue when comparing newer GHRH constructs.

What is it studied alongside?

Sermorelin, CJC-1295 and ipamorelin, typically in comparisons of upstream GH-axis inputs.

How does Neo Labs supply and handle it?

Lyophilised powder, sealed vial, batch COA available against the lot. Cold, light-protected storage.

Primary literature

We link live PubMed searches rather than a fixed citation list, so you always land on the current indexed record — including papers published after this page was reviewed.

The indexed literature for these compounds is predominantly preclinical. Citations are provided for scientific reference and do not imply any human-use indication.
