Tessamorelin

What is Tesamorelin?

Tesamorelin is a synthetic peptide analogue of human growth hormone-releasing hormone (GHRH), comprising the full 44-amino-acid sequence with a trans-3-hexenoic acid moiety attached to the N-terminus to enhance stability. It acts on pituitary somatotroph cells to stimulate the pulsatile secretion of endogenous growth hormone, preserving the physiological feedback mechanisms of the GH/IGF-1 axis.

Research Context

Tesamorelin has been extensively characterized in clinical and preclinical research. Studies have documented its ability to increase IGF-1 levels, reduce visceral adipose tissue accumulation, and improve body composition metrics. Unlike direct GH administration, Tesamorelin maintains pulsatile GH release rather than producing supraphysiological spikes, making it a subject of sustained interest in metabolic and endocrine research.

Research Applications

• GH/IGF-1 axis modulation studies
• Visceral adipose tissue reduction research
• Lipid metabolism and body composition studies
• Pituitary function research
• Cognitive and neuroprotective research models

For research use only. Not for human or animal consumption.

This compound's precise mechanism continues to be characterized through ongoing preclinical research. Investigators have proposed interactions with growth factor signaling pathways, receptor modulation, and cellular repair cascades. Consult current peer-reviewed literature for the most up-to-date mechanistic hypotheses.

Store lyophilized powder at −20°C for up to 24 months. Once reconstituted with bacteriostatic water, store at 4°C and use within 28 days. Protect from light, moisture, and repeated freeze-thaw cycles. Handle in a clean laboratory environment with appropriate PPE. For research use only — not for human or animal administration.

Use our Peptide Reconstitution Calculator to determine the exact volume of bacteriostatic water to add. Allow the solvent to run down the inside of the vial slowly — do not inject directly onto the lyophilized cake. Swirl gently; do not shake. The solution should appear clear to slightly opalescent.
