Tesamorelin is a synthetic 44-amino-acid GHRH analogue, carrying a trans-3-hexenoyl group on the N-terminus that distinguishes it from the native GHRH sequence. It is characterized against the GHRH receptor.
HEEZ Research sells tesamorelin in a single 10 mg lyophilized vial. There is no second strength in the current HEEZ catalogue.
Tesamorelin from HEEZ Research is independently tested by an accredited third-party laboratory using HPLC for purity and mass spectrometry for identity. Every peptide we supply is over 99% pure. Certificates of Analysis are published on the product page as testing is completed — review the report before you order. A certificate records the identity, purity and quantity measured for the material supplied, so you can confirm what you received matches what was ordered.
Sealed lyophilized tesamorelin vials are stable at ambient temperature in transit and ship without cold packaging. On arrival, store the sealed vial per the storage conditions on its certificate of analysis.

About Tesamorelin
What is tesamorelin peptide?
Tesamorelin peptide is a synthetic 44-amino-acid GHRH analogue, supplied by HEEZ Research as a lyophilized powder for in vitro laboratory use. Its sequence is the full-length GHRH(1-44) amide with a trans-3-hexenoyl group on the N-terminal tyrosine — that single acylation distinguishes it from native GHRH(1-44) and from the truncated GHRH(1-29) fragments. Because the whole 44-residue sequence is retained, tesamorelin is the closest full-length reference standard in the GHRH-analogue group.
How does tesamorelin work?
In vitro, tesamorelin is characterized as an agonist at the GHRH receptor family, with the N-terminal acyl group conferring resistance to DPP-4 cleavage in assay media. Receptor activity is measured in GHRH-receptor-expressing cell lines.
How HEEZ tests tesamorelin
Solid-phase synthesis, reversed-phase purification, lyophilization. Independent third-party analysis by HPLC for purity and mass spectrometry for identity, lot-specific certificate (/coa/tesamorelin-coa.webp), purity reported as measured.
