About this peptide
Tesamorelin
Tesamorelin is supplied as a laboratory research material for qualified analytical and in-vitro research environments.
-
01 GHRH analogue
A synthetic 44-residue analogue of human growth-hormone-releasing hormone, GHRH(1-44) amide.
-
02 Stabilised N-terminus
A trans-3-hexenoic acid group on the N-terminal tyrosine resists dipeptidyl peptidase-4 cleavage, the route that degrades native GHRH.
-
03 Characterised sequence
Identity confirmed by mass spectrometry against the published 44-residue sequence; purity by reverse-phase HPLC.
-
04 Research material
Supplied lyophilised at −20°C with a batch certificate of analysis, for analytical and in-vitro use only.
FAQ
Before you order.
Anything not covered here, ask us directly — replies within one working day.
Is a COA included with my order?
Yes. Every vial ships with a certificate of analysis tied to the lot number printed on its label, covering identity by mass spectrometry and purity by HPLC. Retained samples are held so a batch can be re-tested.
How is the product shipped?
Lyophilised powder is stable at ambient temperature in transit and ships in discreet, tracked packaging. UK and EU orders are sent on a priority service; international destinations are quoted at checkout.
How should the vial be stored on arrival?
Keep it sealed at −20°C, protected from light. Lyophilised material is stable for months under those conditions. Once reconstituted, store at 2–8°C and use within the window stated on the certificate of analysis.
Who is this product for?
Qualified researchers and laboratories only. It is supplied strictly as an analytical and in-vitro research material, and is not a medicine, a supplement or a veterinary product.
Why is the half-life so much shorter than the GLP-1 analogues?
Tesamorelin is not acylated for albumin binding. The hexenoyl group protects the N-terminus from enzymatic cleavage but does not extend circulation time the way a fatty-diacid chain does.
