Tesamorelin peptide is a synthetic analogue of the full 44-amino-acid growth hormone-releasing hormone, with a trans-3-hexenoyl group that protects it from rapid breakdown. Vi Corpus supplies Tesamorelin as a 10 mg lyophilised vial for Australian laboratories researching the GH axis and fat metabolism.
Key research features of Tesamorelin peptide
- Full-length GHRH analogue. It keeps all 44 amino acids of natural GHRH, unlike shorter fragments.
- Stabilised N-terminus. The hexenoyl modification resists enzyme cleavage and extends activity.
- Clinical data set. It was approved by the US FDA in 2010 for reducing abdominal fat in HIV-associated lipodystrophy.
- Physiological GH release. It stimulates the pituitary rather than replacing growth hormone.
- Third-party tested. Results are available through our Lab Tests page.

Research applications
Clinical trials showed Tesamorelin reduced visceral adipose tissue while raising IGF-1 within normal ranges. Consequently, it is a reference compound for studies on visceral fat, liver fat and the metabolic effects of growth hormone. Researchers also compare it with CJC-1295 DAC and Ipamorelin to see how different secretagogues shape GH output. In addition, its long clinical record gives labs published reference values for IGF-1 and body composition, which makes study design and comparison far easier.
Storing Tesamorelin peptide
Keep unopened vials refrigerated at 2–8 °C. After mixing with bacteriostatic water, store the solution cold and protect it from light.
Frequently asked questions
Is Tesamorelin a form of somatropin?
No. Somatropin is recombinant growth hormone. Tesamorelin is a GHRH analogue that tells the pituitary to release GH.

Is Tesamorelin for human use?
Not from Vi Corpus. We sell it strictly for laboratory research.
