Tesamorelin in Research
Tesamorelin is a synthetic GHRH analog stabilized with a trans-3-hexenoic acid modification at its N-terminus, giving it improved resistance to DPP-4 cleavage relative to native GHRH. It is among the most clinically documented molecules in the GHRH class, and in preclinical settings it serves as a stabilized reference agonist for sustained GHRH-receptor studies.
Supplied lyophilized at 5mg and ≥99% chromatographic purity, each lot verified by independent HPLC and mass-spectrometry testing with a published certificate of analysis.

Quality & Testing
Every Tesamorelin batch is verified by independent third-party HPLC and mass-spectrometry testing, with a batch-specific certificate of analysis available on the COA page.
Laboratory Handling & Storage
Lyophilized peptides are supplied as a freeze-dried powder and are most stable stored cold (2–8°C), protected from light and moisture, in the original sealed vial. Under these conditions the research literature generally reports multi-year integrity for dry peptide material.
Once reconstituted in a laboratory setting, solutions are typically stored refrigerated and used within the window appropriate to the diluent and compound; repeated freeze–thaw cycles are avoided because they can promote aggregation. See our research overview on reconstitution and lyophilization for the underlying formulation science.
Frequently Asked Questions
What is Tesamorelin?
Tesamorelin is a 44-amino-acid GHRH analog carrying a trans-3-hexenoic acid modification that improves enzymatic stability. In research settings it is used as a stabilized GHRH-receptor agonist reference.
How does Tesamorelin compare with CJC-1295?
Both are stabilized GHRH analogs, but they achieve longevity differently: Tesamorelin through an N-terminal fatty-acid modification, CJC-1295 (with DAC) through covalent albumin binding. Their half-life profiles differ accordingly in the animal literature.
Is Tesamorelin for human use?
No. The material sold here is a laboratory reference compound for research use only — it is not a pharmaceutical product and not for human administration.
