What we test, every batch.
Each production lot of Tesamorelin is analysed by an independent laboratory before it ships. Its certificate is not in our published archive yet — we won't link one we don't hold.

What it is
Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone carrying an acyl group attached at the N-terminus. That modification is the point of the molecule: the unmodified N-terminal region of GHRH is where degrading enzymes attack first, and blocking it changes how long the peptide survives in circulation without altering the receptor-binding sequence itself.
The peptide ships as a lyophilised powder in a sealed glass vial, available in 10 mg and 20 mg presentations. Each lot is accompanied by a Certificate of Analysis documenting compound identity and purity. Supplied as a laboratory reference material for research use only, and not for human or veterinary use.
What the research explores
Tesamorelin is used in the literature as a stabilised comparator against native GHRH and shorter analogues. Areas of published study include:
- How N-terminal acylation affects susceptibility to dipeptidyl peptidase-4 degradation
- Receptor binding and cAMP signalling at GHRHR in pituitary-derived cell models
- Pharmacokinetic profiling of modified versus unmodified GHRH sequences in preclinical species
- Structure-activity relationships across the GHRH analogue family
- Analytical method development for separating the intact peptide from its degradation products
These describe scientific questions under investigation. They are not statements of benefit or outcome, and Elements DNA supplies this material for in vitro and preclinical laboratory use only.
Questions
How should the vial be stored?
Keep the sealed vial cool, dry and shielded from light before opening. After reconstitution, store refrigerated and treat the solution as short-lived. Repeated freeze-thaw cycles degrade peptide integrity.
How is the lyophilised powder reconstituted?
Solvent is typically introduced slowly down the inner wall of the vial and dissolved by gentle swirling rather than shaking. Solvent, working concentration and protocol are determined by the researcher. We do not provide dosing or administration guidance of any kind.
What does the Certificate of Analysis cover?
The batch COA documents identity and chromatographic purity for the specific lot shipped, with its lot identifier and test date. It characterises the material as supplied and is not a clinical or regulatory approval.
What arrives in the shipment?
One sealed glass vial of lyophilised powder in the size selected, protectively packaged and labelled with its batch identifier. Reconstitution solvent and laboratory consumables are not included.
