Tesamorelin 5mg

Tesamorelin is a 44-amino-acid analogue of growth hormone-releasing hormone (GHRH), modified at the N-terminus with a trans-3-hexenoyl group for added stability. It is a reference compound for GHRH-receptor research and is supplied as a lyophilised powder in a 5mg vial.

Research context

Tesamorelin binds the GHRH receptor and is used in research on growth hormone secretion and the GH/IGF-1 axis. Its N-terminal modification protects it from breakdown by the enzyme DPP-4, which is why it is more stable than native GHRH. It is often compared with shorter GHRH analogues such as CJC-1295.

FAQs

What purity is this batch?
The current batch of Tesamorelin tested at 99.06% by HPLC, with identity confirmed by mass spectrometry. The full certificate of analysis, number 026-T82-TSX, is shown below and can be downloaded.

How is Tesamorelin different from native GHRH?
It carries a trans-3-hexenoyl group on its N-terminus, which protects it from enzymatic breakdown and makes it more stable in the lab.

How should it be stored?
Keep the sealed vial at 2–8°C for short-term storage or at −20°C for long-term storage, away from light and moisture. Let a cold vial reach room temperature before opening it.

Is this the same as Tesamorelin acetate?
Yes. Tesamorelin is also written or searched for as Tesamorelin acetate, TH9507 or Tesamorelin peptide. All of these names refer to this GHRH analogue.
