Tesamorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of the first 44 amino acids of human GHRH with a trans-3-hexenoic acid modification at the N-terminus. This structural modification increases resistance to enzymatic degradation by dipeptidyl peptidase IV (DPP-IV), extending the compound's effective half-life in research models.
As a GHRH receptor agonist, tesamorelin acts directly on pituitary somatotroph cells to stimulate the synthesis and secretion of growth hormone. Unlike synthetic GH itself, tesamorelin preserves the natural pulsatile pattern of GH release, making it valuable for studying physiological GH axis signaling.
For detailed molecular mechanisms, see our Tesamorelin Research Peptide Guide.
Tesamorelin is widely used in growth hormone research for several key reasons:

Tesamorelin is studied as a GHRH analog that stimulates pulsatile growth hormone release from pituitary somatotrophs. Research applications include GH/IGF-1 axis signaling and metabolic pathway investigation.
Tesamorelin is a modified GHRH(1-44) analog that directly activates GHRH receptors. Unlike ghrelin receptor agonists like ipamorelin, it works through the GHRH pathway. See our CJC-1295 vs Tesamorelin comparison.
Research-grade tesamorelin should have ≥98% HPLC purity with mass spectrometry confirmation. PeptidesATX provides 99%+ purity with batch-specific COAs.
Store lyophilized tesamorelin at -20°C or below. Once reconstituted with bacteriostatic water, store at 2-8°C and use within 3-4 weeks. See our storage guide.
