Tesamorelin long‑term data – does the fat loss stick after you stop?

This is a 52‑week safety and efficacy study of tesamorelin in HIV patients with abdominal fat accumulation. It reports that visceral adipose tissue decreased during treatment but returned to baseline after the drug was stopped, indicating the effect depends on ongoing exposure.

For me this lines up with what I’ve seen using GH secretagogues – you need regular dosing to keep the metabolic shifts, otherwise the body reverts quickly. The study only covers an HIV cohort, so we can’t assume the same durability or safety in healthy people using it off‑label for body recomposition, and it doesn’t touch on longer term risks beyond a year.

Has anyone tried cycling tesamorelin and noticed whether any fat loss persists off‑cycle, or does it all come back fast? Would love to hear real world experiences from those who’ve run it for a few months then taken a break.

• tracker_jade: Here's a thought: I ran tesamorelin for about 10 weeks total, split into two 5-week runs with a 3-week break in between. I did notice the abdominal area looked softer during the on-periods, and I felt a bit leaner overall. But the moment I stopped the second cycle, things softened up pretty quick, within maybe 2 weeks I was back to baseline, same as the study describes. It wasn't a dramatic rebound, just the metabolic shift disappeared pretty fast. I'm curious if anyone else has had a different
• fasted_scientist: That sounds spot on with what I suspected, ngl. The fact that you felt things soften up within 2 weeks of stopping is a bit gutting, but it matches the study's baseline return. I reckon a 5 week run is probably too short to see any lasting change to the metabolism. I wonder if doing a proper 12 to 16 week stretch would make a difference, or if it is just a temporary shift regardless of the duration.
• fasted_scientist: Ngl that matches what I saw with tesamorelin – the belly looked tighter while I was on it, but as soon as I stopped the softness crept back in about ten days later. Feels like the effect needs constant exposure, not just a quick cycle. Anyone tried longer runs to see if it sticks?
