Research overview

Tesamorelin is a synthetic 44-amino-acid peptide and a stabilized analog of growth-hormone-releasing hormone (GHRH). Its structure is written as trans-3-hexenoyl-Tyr-hGRF(1-44)-NH2, meaning the hGRF(1-44) sequence carries a trans-3-hexenoyl group on the N-terminal tyrosine and an amidated C-terminus. It is catalogued under CAS 218949-48-5 with the molecular formula C221H366N72O67S. The hexenoyl modification is what sets it apart from unmodified GRF(1-44) at the chemical level. In the scientific literature, Tesamorelin is referenced within metabolic and endocrine research, alongside other GHRH-analog and growth-hormone-releasing peptides. It turns up in structural and comparative studies of this peptide class, and in work on peptide chemistry and growth-hormone-axis endocrinology as a research topic. Each lot is supplied as a lyophilized powder and ships with a third-party certificate of analysis specific to that batch, so identity and purity can be confirmed on a per-lot basis. Tesamorelin is stocked in 5mg and 10mg vials, supplied as a reference standard for laboratory research use only and not for human or veterinary use. Orders ship tracked from our Vancouver facility to research addresses across Canada, which makes it straightforward to buy Tesamorelin in Canada as third-party tested reference material.

Tesamorelin is a stabilized GHRH (growth-hormone-releasing hormone) analog peptide that appears in metabolic and endocrine research literature. It is referenced in structural and comparative studies of growth-hormone-releasing peptides.
