Tesamorelin research overview
Tesamorelin is a synthetic analogue of full-length human growth-hormone-releasing hormone, GHRH(1-44), carrying a trans-3-hexenoyl group at its N-terminus — a structural modification that increases resistance to enzymatic degradation. TrueBond Labs stocks tesamorelin as a 10 mg lyophilized powder in a 3 mL vial intended for laboratory research. Third-party HPLC testing confirms no less than 99% purity, and mass spectrometry validates identity, before the lot enters inventory.
In published work, tesamorelin is used in laboratory investigations of GHRH-receptor pharmacology and has been studied in preclinical research examining growth-hormone-axis signaling. Because of its stabilized structure, it also features in peptide-chemistry studies comparing degradation behavior among GRF analogues. None of this constitutes a claim of effect; researchers who buy tesamorelin from TrueBond Labs do so under research-use-only terms, for in-vitro applications conducted by qualified professionals.
Every tesamorelin batch ships with lot-level documentation viewable at /lab-reports, pairing an HPLC purity result with an MS identity confirmation. Stability guidance mirrors our other lyophilized research peptides: −20°C storage supports 24+ months, and reconstituted solutions are held at 2–8°C for around 30 days. For lot TB-TES-001, the paired figures read 99.6% purity and a confirmed 10.15 mg net fill.

Tesamorelin — frequently asked questions
What is tesamorelin?+
Tesamorelin is a stabilized synthetic version of the complete 44-amino-acid human GHRH sequence, distinguished by a trans-3-hexenoyl modification at the N-terminus that slows enzymatic breakdown. It appears in laboratory research on GHRH-receptor signaling. TrueBond Labs supplies it purely as a research peptide for in-vitro study, with no instructions provided or implied.
How does tesamorelin differ from sermorelin?+
The distinction is structural. Sermorelin reproduces only the first 29 amino acids of GHRH — the GRF(1-29) fragment — while tesamorelin spans the full 44-residue sequence and adds an N-terminal hexenoyl group for enzymatic stability. Both are catalogued here as separate research peptides, each with its own lot-level COA published at /lab-reports.
Is tesamorelin from TrueBond Labs third-party tested?+
Yes. An independent third-party laboratory analyzes each tesamorelin lot before release, running HPLC to verify purity of 99% or higher and mass spectrometry to confirm the molecule's identity. That certificate is published openly at /lab-reports; look up your vial's lot code there to see the exact report for your batch.
What storage conditions does tesamorelin require?+
Hold lyophilized tesamorelin at −20°C for long-term stability of 24+ months, keeping it away from light. Once reconstituted for laboratory procedures, transfer the vial to 2–8°C refrigeration and use the solution within roughly 30 days. Repeated freezing and thawing should be avoided to protect the verified material.
