What is tesamorelin?
Tesamorelin is a synthetic analogue of human growth hormone-releasing hormone (GHRH). It contains all 44 amino acids of natural GHRH with a trans-3-hexenoyl group added at the start, which protects it from breakdown by enzymes. It acts on the GHRH receptor in the pituitary gland.

Regulatory status
Tesamorelin is the active ingredient of a prescription medicine approved in the US (Egrifta). This product is research material, not that medicine, and is sold for laboratory research use only. GHRH analogues are prohibited at all times in competitive sport by the World Anti-Doping Agency.
Available sizes: 5mg, 10mg and 20mg
Tesamorelin is offered in three vial sizes: 5mg, 10mg and 20mg. All contain the same peptide. The figure is the total amount of peptide in the vial, supplied as a dry (lyophilised) powder; it is not a concentration, so a larger vial is not “stronger”, it simply holds more material.
