Description
A growth-hormone-releasing hormone (GHRH) analog studied for its ability to stimulate the pituitary’s natural growth hormone output, with particular research interest in fat metabolism.
Tesamorelin is full-length GHRH(1-44) carrying a small hexenoyl group on the N-terminus. At 44 residues and over 5100 Da it is the largest single peptide in this catalogue, and the acyl group is what protects the otherwise vulnerable N-terminal region from cleavage.

Tesamorelin is supplied for laboratory research use only. It is not a drug, food or cosmetic, and it is not for human or veterinary use.
| Reconstitution | Bacteriostatic water or sterile water. |
|---|---|
| Storage, lyophilised | -20 °C, sealed and desiccated, protected from light. |
| Storage, reconstituted | 2-8 °C, protected from light. Use within 2-4 weeks, or freeze single-use aliquots at -20 °C for longer holds. |
| Shipping | Shipped at ambient temperature. Lyophilised material tolerates transit without a cold chain; move it to the freezer on arrival. |
Working notes
- Let a vial come to room temperature before opening it. Opening a cold vial draws in moist air, and lyophilised powder takes up water quickly.
- Add the diluent slowly down the inside wall of the vial rather than directly onto the powder cake, and let it dissolve on its own. Shaking a peptide solution is the fastest way to denature it.
- Wipe the stopper with alcohol before every draw, and keep solutions out of direct light.
- Repeated freeze-thaw cycles cost you more purity than time in the fridge does. If a vial will be used over weeks, aliquot it once and freeze the aliquots.
