Research Background
Tesamorelin is a 44-amino-acid GHRH analogue: the full-length GHRH(1-44) sequence with a trans-3-hexenoyl modification at the N-terminus that increases resistance to DPP-IV cleavage. That stability difference is the reason it is used in GH-axis research where a longer-acting GHRH-receptor stimulus is required, as distinct from the shorter GHRH(1-29) analogue Sermorelin.

FAQ
What is Tesamorelin?
Tesamorelin (CAS 218949-48-5) is a stabilised GHRH(1-44) analogue used as a research reagent in growth-hormone-axis studies.
How does it differ from Sermorelin?
Sermorelin is GHRH(1-29); Tesamorelin is the full-length GHRH(1-44) with an N-terminal modification that slows enzymatic degradation, so research designs differ in the duration of receptor stimulation.
Which kit sizes are available?
5 mg, 10 mg and 20 mg × 10-vial kits — the widest configuration range in our GH-axis portfolio.
Do you supply research documentation?
Yes: batch-specific COA, and MS/HPLC data on request. Our documentation is analytical, not regulatory — these are research reagents.
All products are manufactured for laboratory research purposes only. Tesamorelin is labeled FOR LABORATORY RESEARCH USE ONLY. Not for human or veterinary use, diagnosis, treatment, prophylaxis or any clinical, cosmetic, dietary or household application.
