About Tesa (tesamorelin)
Tesamorelin is the full 44-amino-acid GHRH with a trans-3-hexenoyl group added. It’s FDA-approved as Egrifta for reducing abdominal fat in HIV-associated lipodystrophy.
It raises GH and IGF-1.
How Tesa acts in the lab
Tesamorelin binds the GHRH receptor and raises growth hormone and IGF-1. The hexenoyl group on the front end stops DPP-4 from cutting it, which makes it far more stable than natural GHRH.
Its best-documented effect is on visceral fat, the fat around the organs, which is what the Egrifta approval was based on.

How to reconstitute Tesa 5mg
The volume of water you add sets the concentration. For a vial holding 5mg:
- 1ml of bacteriostatic water gives 5mg/ml
- 2ml of bacteriostatic water gives 2.5mg/ml
- 3ml of bacteriostatic water gives 1.67mg/ml
Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.
Most labs use bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll it gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
Storing Tesa 5mg
The dry powder keeps best cold: 2 to 8°C in the fridge, or -20°C for long-term storage. After reconstitution, store it in the fridge and finish it within roughly four weeks.
