Specification and laboratory information
Tesamorelin 10mg is supplied as a lyophilised research peptide in a sealed vial. Review the compound specification below and confirm the document for the batch you require before ordering.
Laboratory and analytical research only. Not for human consumption. Orders restricted to adults aged 18 or over.
Tesamorelin is a fully synthetic 44-residue peptide amide corresponding to the GHRH(1–44) sequence, distinguished by a trans-3-hexenoyl group acylated onto the α-amino group of the N-terminal tyrosine. That lipophilic N-terminal modification is the structural feature defining it as a discrete entity within the GHRH analogue family, and it's the feature most often referenced in analytical method development and stability profiling.
At 5136 g/mol across 44 residues, this is the largest peptide on our catalogue. Supplied as a lyophilised powder in a sealed single-use vial.

Storage and handling
Store sealed at −20°C, protected from light and moisture. Equilibrate to ambient temperature before opening. Larger peptides are generally more sensitive to freeze-thaw cycling than short chains — avoid repeated temperature excursions. Refer to the lot COA for batch-specific data.
