Tesamorelin research guide · Updated 24 Oct 2026

What is Tesamorelin?

Tesamorelin is a synthetic analog of growth hormone releasing hormone (GHRH). It contains all 44 amino acids of human GHRH, with a trans-3-hexenoyl group added to the first amino acid, a change that makes it more stable than natural GHRH. It is studied in growth hormone research. It is supplied as a lyophilized powder for in vitro and preclinical laboratory research only.

Full specifications

Sequence: 44-residue GHRH(1-44) analog: trans-3-hexenoyl-Tyr1 N-terminal acylation
Length: 44 amino acids
CAS number: 218949-48-5
Molecular formula: C221H366N72O67S
Molecular weight: 5135.9 g/mol
Form: Lyophilized powder in a glass vial
Purity standard: 98% or higher (brand listing)
Storage: Minus 20 °C long term. 2 to 8 °C once reconstituted, use within 30 days.

How Tesamorelin is tested

A good Tesamorelin listing comes with a lab report for the exact lot in the vial. These are the results to look for:

Purity (HPLC)
How much of the sample is the compound
Identity (MS or LCMS)
Confirms it is the right molecule
Net content
The real mg in the vial versus the label
Endotoxin (LAL)
Bacterial residue, reported in EU
Sterility
Confirms nothing is growing in the vial
Heavy metals (ICP-MS)
Arsenic, cadmium, lead and mercury

Storage and handling

Lyophilized Tesamorelin is stable at room temperature while it ships. For long term storage keep vials at minus 20 °C. Once reconstituted for laboratory use, store at 2 to 8 °C and use within 30 days.

Tesamorelin vs sermorelin

Both are GHRH analogs. Tesamorelin uses the full 44 amino acid GHRH sequence with a stabilizing group. Sermorelin is the first 29 amino acids of GHRH. Tesamorelin is also sold in a blend with ipamorelin.
