Tesamorelin
Stabilized GHRH analog (44-mer) · endocrine-pathway research materials
Tesamorelin is a synthetic 44-amino-acid peptide, a stabilized analog of human growth-hormone-releasing hormone (GHRH). It is supplied as a lyophilized powder as a research reference material.
Research context
In published research, GHRH analogs such as tesamorelin are investigated in the context of growth-hormone-axis and metabolic-signaling pathway research using in-vitro and preclinical models. Glow Peptides supplies Tesamorelin strictly as a reference material for such in-vitro and preclinical research. It is not a therapeutic product and is not for human or veterinary use.
Handling & storage
Tesamorelin is supplied lyophilized (freeze-dried). General laboratory handling practice for research materials of this type:
- Sealed vials: store lyophilized powder cold and away from light; long-term storage is typically in a freezer. Sealed, dry vials are stable far longer than reconstituted material.
- Reconstitution: research protocols typically reconstitute with bacteriostatic or sterile water introduced slowly against the vial wall, swirled (not shaken) until dissolved. See our reconstitution & storage guide.
- After reconstitution: keep refrigerated and protected from light; material in solution is less stable than the dry powder.
- Documentation: record the lot number and its Certificate of Analysis for your records.
Quality & testing
Every lot of Tesamorelin we supply is independently tested at a U.S. laboratory and ships with a lot-specific Certificate of Analysis. Testing includes HPLC with UV detection for purity and mass spectrometry for identity, with our purity standard at ≥99%.
You can search any lot and view its documentation on our Quality & COA verification page, and learn what the numbers mean in how to read a Certificate of Analysis. Our published customer rating is 4.5 on Trustpilot.
Tesamorelin is available as an independently tested, ≥99%-purity research reference material with a per-lot Certificate of Analysis.

Is Tesamorelin intended for human use?
No. Tesamorelin is supplied strictly as a reference material for in-vitro laboratory and preclinical research. It is not a drug or supplement and is not for human or veterinary use.
How is Tesamorelin tested for purity?
Each lot is independently tested at a U.S. laboratory by HPLC with UV detection (purity) and mass spectrometry (identity), and ships with a lot-specific Certificate of Analysis. Our purity standard is ≥99%.
How should Tesamorelin be stored?
Sealed lyophilized vials are stored cold and away from light, typically frozen for long-term storage. Once reconstituted for research, material is kept refrigerated and protected from light.
