Short answer
The label says tesamorelin has a weight-neutral effect, so weight gain is not an expected result, although it lists fluid retention as a warning.[1]
Weight, fluid and lean mass
Fluid retention can occur, which the label says is linked to growth hormone induction and can show up as edema.[1]
A pooled analysis of four trials found lean body mass rose with tesamorelin while trunk fat fell.[2]
In rats and dogs dosed repeatedly, body weight gain was significantly higher in treated animals (animal data).[3]
