The catalogue carries the releasing-hormone analogue and the hormone itself, and they are not the same thing

Published 26 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Tesamorelin is a 44-residue analogue of growth hormone-releasing hormone with a modified amino terminus that resists degradation; it acts on the pituitary to release the body own growth hormone in its natural pulsatile pattern, subject to somatostatin and IGF-1 feedback. Somatropin is the 191-residue hormone itself; it acts directly on receptors in liver, muscle, fat and bone, bypassing the pituitary and its feedback. The two are different molecules, different mechanisms and different research questions, which is why the catalogue carries both.

What tesamorelin is

The releasing hormone with a trans-3-hexenoyl group on its first residue, which protects it from the enzyme that inactivates the natural peptide within minutes. It binds the releasing-hormone receptor on somatotrophs. Its effect depends on a functioning pituitary and is limited by the feedback loops, so growth hormone released in response stays within a physiological pattern. It is an approved medicine for one indication and is in this catalogue as a research peptide.

The Tesamorelin 20 mg pack is the catalogue entry.

What somatropin is

The hormone. It needs no pituitary and is subject to no release feedback — the amount present is the amount introduced. It acts on the growth hormone receptor wherever it is expressed. Its pharmacology is that of a replacement, not a stimulus.

The 24 mg pack is the catalogue entry.

Why the distinction matters in research

A question about the pituitary, about pulsatility or about the releasing-hormone receptor is a tesamorelin question. A question about the hormone acting on a tissue, or about the receptor and its signalling, is a somatropin question. The literature on each is distinct and the pages for each product cite its own.
