Tesamorelin is a 44-amino-acid GHRH analogue carrying a trans-3-hexenoyl group on the N-terminal tyrosine and a C-terminal amide. It is supplied lyophilized, typically as the acetate salt.

Testing and documentation
Every lot of Tesamorelin supplied by Never Enough Labs is analysed by an independent laboratory using High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) to confirm identity and purity before release. The Certificate of Analysis for your lot is attached to this listing and is also searchable by lot number in the COA Library.
If you are new to reading analytical documentation, see our guide on how to read a Certificate of Analysis.
Handling
Lyophilized material should be brought to room temperature before opening to limit condensation. Reconstitute gently — direct the diluent against the vial wall rather than onto the powder, and swirl rather than shake. Record the lot number and reconstitution date; the storage conditions above apply from that point forward.
